-----------------------------------------------------------------------------
-
-1. NOTE 
-This software has been successfully in alpha and beta test and is part of
-the standard kernel since kernel 1.1.8x since December 1994. It works with
-AZTECH CDA268-01A, ORCHID CDS-3110, ORCHID/WEARNES CDD110 and CONRAD TXC 
-(Nr.99 31 23 -series 04) and has proven to be stable with kernel 
-versions 1.0.9 and newer. But with any software there still may be bugs in it. 
-So if you encounter problems, you are invited to help us improve this software. 
-Please send me a detailed bug report (see chapter BUG REPORTS). You are also 
-invited in helping us to increase the number of drives, which are supported.
-
-Please read the README-files carefully and always keep a backup copy of your 
-old kernel, in order to reboot if something goes wrong!
-
-2. INSTALLATION
-The driver consists of a header file 'aztcd.h', which normally should reside 
-in /usr/src/linux/drivers/cdrom and the source code 'aztcd.c', which normally 
-resides in the same place. It uses /dev/aztcd (/dev/aztcd0 in some distri-
-butions), which must be a valid block device with major number 29 and reside 
-in directory /dev. To mount a CD-ROM, your kernel needs to have the ISO9660-
-filesystem support included.
-
-PLEASE NOTE: aztcd.c has been developed in parallel to the linux kernel,
-which had and is having many major and minor changes which are not backward
-compatible. Quite definitely aztcd.c version 1.80 and newer will NOT work
-in kernels older than 1.3.33. So please always use the most recent version
-of aztcd.c with the appropriate linux-kernel.
-
-3.  CONFIGURING YOUR KERNEL
-If your kernel is already configured for using the AZTECH driver you will
-see the following message while Linux boots:
-    Aztech CD-ROM Init: DriverVersion=<version number> BaseAddress=<baseaddress>
-    Aztech CD-ROM Init: FirmwareVersion=<firmware version id of your I/O-card>>>
-    Aztech CD-ROM Init: <drive type> detected
-    Aztech CD-ROM Init: End
-If the message looks different and you are sure to have a supported drive,
-it may have a different base address. The Aztech driver does look for the 
-CD-ROM drive at the base address specified in aztcd.h at compile time. This 
-address can be overwritten by boot parameter aztcd=....You should reboot and 
-start Linux with boot parameter aztcd=<base address>, e.g. aztcd=0x320. If 
-you do not know the base address, start your PC with DOS and look at the boot 
-message of your CD-ROM's DOS driver. If that still does not help, use boot
-parameter aztcd=<base address>,0x79 , this tells aztcd to try a little harder.
-aztcd may be configured to use autoprobing the base address by recompiling
-it (see chapter 4.).
-
-If the message looks correct, as user 'root' you should be able to mount the 
-drive by
-          mount -t iso9660 -r /dev/aztcd0 /mnt
-and use it as any other filesystem. (If this does not work, check if
-/dev/aztcd0 and /mnt do exist and create them, if necessary by doing
-      mknod /dev/aztcd0 b 29 0
-      mkdir /mnt                       
-
-If you still get a different message while Linux boots or when you get the 
-message, that the ISO9660-filesystem is not supported by your kernel, when
-you try to mount the CD-ROM drive, you have to recompile your kernel.
-
-If you do *not* have an Aztech/Orchid/Okano/Wearnes/TXC drive and want to 
-bypass drive detection during Linux boot up, start with boot parameter aztcd=0.
-
-Most distributions nowadays do contain a boot disk image containing aztcd.
-Please note, that this driver will not work with IDE/ATAPI drives! With these 
-you must use ide-cd.c instead.
-
-4. RECOMPILING YOUR KERNEL
-If your kernel is not yet configured for the AZTECH driver and the ISO9660-
-filesystem, you have to recompile your kernel: 
-
-- Edit aztcd.h to set the I/O-address to your I/O-Base address (AZT_BASE_ADDR), 
-  the driver does not use interrupts or DMA, so if you are using an AZTECH
-  CD268, an ORCHID CD-3110 or ORCHID/WEARNES CDD110 that's the only item you 
-  have to set up. If you have a soundcard, read chapter 4.2.
-  Users of other drives should read chapter OTHER DRIVES of this file.
-  You also can configure that address by kernel boot parameter aztcd=... 
-- aztcd may be configured to use autoprobing the base address by setting
-  AZT_BASE_ADDR to '-1'. In that case aztcd probes the addresses listed 
-  under AZT_BASE_AUTO. But please remember, that autoprobing always may 
-  incorrectly influence other hardware components too!
-- There are some other points, which may be configured, e.g. auto-eject the
-  CD when unmounting a drive, tray locking etc., see aztcd.h for details.
-- If you're using a linux kernel version prior to 2.1.0, in aztcd.h
-  uncomment the line '#define AZT_KERNEL_PRIOR_2_1'
-- Build a new kernel, configure it for 'Aztech/Orchid/Okano/Wearnes support' 
-  (if you want aztcd to be part of the kernel). Do not configure it for
-  'Aztech... support', if you want to use aztcd as a run time loadable module. 
-  But in any case you must have the ISO9660-filesystem included in your
-  kernel.
-- Activate the new kernel, normally this is done by running LILO (don't for-
-  get to configure it before and to keep a copy of your old kernel in case
-  something goes wrong!).
-- Reboot
-- If you've included aztcd in your kernel, you now should see during boot 
-  some messages like
-    Aztech CD-ROM Init: DriverVersion=<version number> BaseAddress=<baseaddress>
-    Aztech CD-ROM Init: FirmwareVersion=<firmware version id of your I/O-card>
-    Aztech CD-ROM Init: <drive type> detected
-    Aztech CD-ROM Init: End
-- If you have not included aztcd in your kernel, but want to load aztcd as a 
-  run time loadable module see 4.1. 
-- If the message looks correct, as user 'root' you should be able to mount 
-  the drive by
-          mount -t iso9660 -r /dev/aztcd0 /mnt
-  and use it as any other filesystem. (If this does not work, check if
-  /dev/aztcd0 and /mnt do exist and create them, if necessary by doing
-      mknod /dev/aztcd0 b 29 0
-      mkdir /mnt                       
-- If this still does not help, see chapters OTHER DRIVES and DEBUGGING.
-
-4.1 AZTCD AS A RUN-TIME LOADABLE MODULE
-If you do not need aztcd permanently, you can also load and remove the driver
-during runtime via insmod and rmmod. To build aztcd as a loadable module you 
-must configure your kernel for AZTECH module support (answer 'm' when con-
-figuring the kernel). Anyhow, you may run into problems, if the version of 
-your boot kernel is not the same than the source kernel version, from which 
-you create the modules. So rebuild your kernel, if necessary. 
-
-Now edit the base address of your AZTECH interface card in
-/usr/src/linux/drivers/cdrom/aztcd.h to the appropriate value. 
-aztcd may be configured to use autoprobing the base address by setting
-AZT_BASE_ADDR to '-1'. In that case aztcd probes the addresses listed 
-under AZT_BASE_AUTO. But please remember, that autoprobing always may 
-incorrectly influence other hardware components too!
-There are also some special features which may be configured, e.g. 
-auto-eject a CD when unmounting the drive etc; see aztcd.h for details. 
-Then change to /usr/src/linux and do a 
-                    make modules  
-	            make modules_install
-After that you can run-time load the driver via
-                    insmod /lib/modules/X.X.X/misc/aztcd.o
-and remove it via   rmmod  aztcd.
-If you did not set the correct base address in aztcd.h, you can also supply the
-base address when loading the driver via
-                    insmod /lib/modules/X.X.X/misc/aztcd.o aztcd=<base address>
-Again specifying aztcd=-1 will cause autoprobing.
-If you do not have the iso9660-filesystem in your boot kernel, you also have
-to load it before you can mount the CDROM:
-                    insmod /lib/modules/X.X.X/fs/isofs.o
-The mount procedure works as described in 4. above.
-(In all commands 'X.X.X' is the current linux kernel version number)
-
-4.2 CDROM CONNECTED TO A SOUNDCARD
-Most soundcards do have a bus interface to the CDROM-drive. In many cases
-this soundcard needs to be configured, before the CDROM can be used. This
-configuration procedure consists of writing some kind of initialization
-data to the soundcard registers. The AZTECH-CDROM driver in the moment does
-only support one type of soundcard (SoundWave32). Users of other soundcards
-should try to boot DOS first and let their DOS drivers initialize the
-soundcard and CDROM, then warm boot (or use loadlin) their PC to start
-Linux.
-Support for the CDROM-interface of SoundWave32-soundcards is directly
-implemented in the AZTECH driver. Please edit linux/drivers/cdrom/aztdc.h,
-uncomment line '#define AZT_SW32' and set the appropriate value for
-AZT_BASE_ADDR and AZT_SW32_BASE_ADDR. This support was tested with an Orchid
-CDS-3110 connected to a SoundWave32.
-If you want your soundcard to be supported, find out, how it needs to be
-configured and mail me (see 6.) the appropriate information. 
-
-5. KNOWN PROBLEMS, FUTURE DEVELOPMENTS
-5.1 MULTISESSION SUPPORT
-Multisession support for CD's still is a myth. I implemented and tested a basic
-support for multisession and XA CDs, but I still have not enough CDs and appli-
-cations to test it rigorously. So if you'd like to help me, please contact me
-(Email address see below). As of version 1.4 and newer you can enable the 
-multisession support in aztcd.h by setting AZT_MULTISESSION to 1. Doing so 
-will cause the ISO9660-filesystem to deal with multisession CDs, ie. redirect 
-requests to the Table of Contents (TOC) information from the last session, 
-which contains the info of all previous sessions etc.. If you do set 
-AZT_MULTISESSION to 0, you can use multisession CDs anyway. In that case the 
-drive's firmware will do automatic redirection. For the ISO9660-filesystem any 
-multisession CD  will then look like a 'normal' single session CD. But never-
-theless the data of all sessions are viewable and accessible. So with practical-
-ly all real world applications you won't notice the difference. But as future
-applications may make use of advanced multisession features, I've started to
-implement the interface for the ISO9660 multisession interface via ioctl
-CDROMMULTISESSION.
-
-5.2 STATUS RECOGNITION
-The drive status recognition does not work correctly in all cases. Changing
-a disk or having the door open, when a drive is already mounted, is detected 
-by the Aztech driver itself, but nevertheless causes multiple read attempts
-by the different layers of the ISO9660-filesystem driver, which finally timeout,
-so you have to wait quite a little... But isn't it bad style to change a disk 
-in a mounted drive, anyhow ?!
-
-The driver uses busy wait in most cases for the drive handshake (macros
-STEN_LOW and DTEN_LOW). I tested with a 486/DX2 at 66MHz and a Pentium at
-60MHz and 90MHz. Whenever you use a much faster machine you are likely to get 
-timeout messages. In that case edit aztcd.h and increase the timeout value 
-AZT_TIMEOUT. 
-
-For some 'slow' drive commands I implemented waiting with a timer waitqueue
-(macro STEN_LOW_WAIT). If you get this timeout message, you may also edit
-aztcd.h and increase the timeout value AZT_STATUS_DELAY. The waitqueue has
-shown to be a little critical. If you get kernel panic messages, edit aztcd.c
-and substitute STEN_LOW_WAIT by STEN_LOW. Busy waiting with STEN_LOW is more
-stable, but also causes CPU overhead.
-
-5.3 DOSEMU's CD-ROM SUPPORT
-With release 1.20 aztcd was modified to allow access to CD-ROMS when running
-under dosemu-0.60.0 aztcd-versions before 1.20 are most likely to crash
-Linux, when a CD-ROM is accessed under dosemu. This problem has partly been
-fixed, but still when accessing a directory for the first time the system
-might hang for some 30sec. So be patient, when using dosemu's CD-ROM support
-in combination with aztcd :-) ! 
-This problem has now (July 1995) been fixed by a modification to dosemu's
-CD-ROM driver. The new version came with dosemu-0.60.2, see dosemu's
-README.CDROM.
-
-6. BUG REPORTS
-Please send detailed bug reports and bug fixes via EMail to
-
-        Werner.Zimmermann@fht-esslingen.de
-
-Please include a description of your CD-ROM drive type and interface card, 
-the exact firmware message during Linux bootup, the version number of the 
-AZTECH-CDROM-driver and the Linux kernel version. Also a description of your 
-system's other hardware could be of interest, especially microprocessor type, 
-clock frequency, other interface cards such as soundcards, ethernet adapter, 
-game cards etc..
-
-I will try to collect the reports and make the necessary modifications from 
-time to time. I may also come back to you directly with some bug fixes and 
-ask you to do further testing and debugging.
-
-Editors of CD-ROMs are invited to send a 'cooperation' copy of their
-CD-ROMs to the volunteers, who provided the CD-ROM support for Linux. My
-snail mail address for such 'stuff' is

-7. OTHER DRIVES
-The following drives ORCHID CDS3110, OKANO CDD110, WEARNES CDD110 and Conrad
-TXC Nr. 993123-series 04 nearly look the same as AZTECH CDA268-01A, especially 
-they seem to use the same command codes. So it was quite simple to make the 
-AZTECH driver work with these drives. 
-
-Unfortunately I do not have any of these drives available, so I couldn't test
-it myself. In some installations, it seems necessary to initialize the drive 
-with the DOS driver before (especially if combined with a sound card) and then 
-do a warm boot (CTRL-ALT-RESET) or start Linux from DOS, e.g. with 'loadlin'.
-
-If you do not succeed, read chapter DEBUGGING. Thanks in advance!
-
-Sorry for the inconvenience, but it is difficult to develop for hardware, 
-which you don't have available for testing. So if you like, please help us.
-
-If you do have a CyCDROM CR520ie thanks to Hilmar Berger's help your chances
-are good, that it will work with aztcd. The CR520ie is sold as an IDE-drive
-and really is connected to the IDE interface (primary at 0x1F0 or secondary
-at 0x170, configured as slave, not as master). Nevertheless it is not ATAPI
-compatible but still uses Aztech's command codes.
-
-
-8. DEBUGGING : IF YOU DON'T SUCCEED, TRY THE FOLLOWING
--reread the complete README file
--make sure, that your drive is hardware configured for 
-    transfer mode: polled
-    IRQ:           not used
-    DMA:           not used
-    Base Address:  something like 300, 320 ...
- You can check this, when you start the DOS driver, which came with your
- drive. By appropriately configuring the drive and the DOS driver you can
- check, whether your drive does operate in this mode correctly under DOS. If
- it does not operate under DOS, it won't under Linux.
- If your drive's base address is something like 0x170 or 0x1F0 (and it is
- not a CyCDROM CR520ie or CR 940ie) you most likely are having an IDE/ATAPI-
- compatible drive, which is not supported by aztcd.c, use ide-cd.c instead.
- Make sure the Base Address is configured correctly in aztcd.h, also make
- sure, that /dev/aztcd0 exists with the correct major number (compare it with
- the entry in file /usr/include/linux/major.h for the Aztech drive). 
--insert a CD-ROM and close the tray
--cold boot your PC (i.e. via the power on switch or the reset button)
--if you start Linux via DOS, e.g. using loadlin, make sure, that the DOS
- driver for the CD-ROM drive is not loaded (comment out the calling lines 
- in DOS' config.sys!)
--look for the aztcd: init message during Linux init and note them exactly
--log in as root and do a mount -t iso9660 /dev/aztcd0 /mnt
--if you don't succeed in the first time, try several times. Try also to open
- and close the tray, then mount again. Please note carefully all commands
- you typed in and the aztcd-messages, which you get.
--if you get an 'Aztech CD-ROM init: aborted' message, read the remarks about
- the version string below.
-
-If this does not help, do the same with the following differences 
--start DOS before; make now sure, that the DOS driver for the CD-ROM is 
- loaded under DOS (i.e. uncomment it again in config.sys)
--warm boot your PC (i.e. via CTRL-ALT-DEL)
- if you have it, you can also start via loadlin (try both).
- ...
- Again note all commands and the aztcd-messages.
-
-If you see STEN_LOW or STEN_LOW_WAIT error messages, increase the timeout
-values.
-
-If this still does not help, 
--look in aztcd.c for the lines  #if 0
-                                #define AZT_TEST1
-                                ...
-                                #endif
- and substitute '#if 0' by '#if 1'.
--recompile your kernel and repeat the above two procedures. You will now get 
- a bundle of debugging messages from the driver. Again note your commands
- and the appropriate messages. If you have syslogd running, these messages
- may also be found in syslogd's kernel log file. Nevertheless in some
- installations syslogd does not yet run, when init() is called, thus look for
- the aztcd-messages during init, before the login-prompt appears.
- Then look in aztcd.c, to find out, what happened. The normal calling sequence 
- is: aztcd_init() during Linux bootup procedure init()
- after doing a 'mount -t iso9660 /dev/aztcd0 /mnt' the normal calling sequence is
-     aztcd_open()    -> Status 2c after cold reboot with CDROM or audio CD inserted
-                     -> Status 8  after warm reboot with CDROM inserted          
-                     -> Status 2e after cold reboot with no disk, closed tray
-                     -> Status 6e after cold reboot, mount with door open
-     aztUpdateToc()
-     aztGetDiskInfo()
-     aztGetQChannelInfo()   repeated several times
-     aztGetToc()
-     aztGetQChannelInfo()   repeated several times
-     a list of track information
-     do_aztcd_request()  }  
-     azt_transfer()    } repeated several times
-     azt_poll          }
- Check, if there is a difference in the calling sequence or the status flags!
- 
- There are a lot of other messages, eg. the ACMD-command code (defined in
- aztcd.h), status info from the getAztStatus-command and the state sequence of
- the finite state machine in azt_poll(). The most important are the status
- messages, look how they are defined and try to understand, if they make
- sense in the context where they appear. With a CD-ROM inserted the status 
- should always be 8, except in aztcd_open(). Try to open the tray, insert an
- audio disk, insert no disk or reinsert the CD-ROM and check, if the status
- bits change accordingly. The status bits are the most likely point, where 
- the drive manufacturers may implement changes.
-            
-If you still don't succeed, a good point to start is to look in aztcd.c in 
-function aztcd_init, where the drive should be detected during init. Do the
-following:
--reboot the system with boot parameter 'aztcd=<your base address>,0x79'. With
- parameter 0x79 most of the drive version detection is bypassed. After that 
- you should see the complete version string including leading and trailing 
- blanks during init. 
- Now adapt the statement
-      if ((result[1]=='A')&&(result[2]=='Z' ...)
- in aztcd_init() to exactly match the first 3 or 4 letters you have seen.
--Another point is the 'smart' card detection feature in aztcd_init(). Normally
- the CD-ROM drive is ready, when aztcd_init is trying to read the version
- string and a time consuming ACMD_SOFT_RESET command can be avoided. This is
- detected by looking, if AFL_OP_OK can be read correctly. If the CD-ROM drive 
- hangs in some unknown state, e.g. because of an error before a warm start or 
- because you first operated under DOS, even the version string may be correct, 
- but the following commands will not. Then change the code in such a way, 
- that the ACMD_SOFT_RESET is issued in any case, by substituting the
- if-statement 'if ( ...=AFL_OP_OK)' by 'if (1)'.
-
-If you succeed, please mail me the exact version string of your drive and
-the code modifications, you have made together with a short explanation.
-If you don't succeed, you may mail me the output of the debugging messages.
-But remember, they are only useful, if they are exact and complete and you
-describe in detail your hardware setup and what you did (cold/warm reboot,
-with/without DOS, DOS-driver started/not started, which Linux-commands etc.)
-
-
-9. TECHNICAL HISTORY OF THE DRIVER
-The AZTECH-Driver is a rework of the Mitsumi-Driver. Four major items had to
-be reworked:
-
-a) The Mitsumi drive does issue complete status information acknowledging
-each command, the Aztech drive does only signal that the command was
-processed. So whenever the complete status information is needed, an extra
-ACMD_GET_STATUS command is issued. The handshake procedure for the drive
-can be found in the functions aztSendCmd(), sendAztCmd() and getAztStatus().
-
-b) The Aztech Drive does not have a ACMD_GET_DISK_INFO command, so the
-necessary info about the number of tracks (firstTrack, lastTrack), disk
-length etc. has to be read from the TOC in the lead in track (see function
-aztGetDiskInfo()).
-
-c) Whenever data is read from the drive, the Mitsumi drive is started with a
-command to read an indefinite (0xffffff) number of sectors. When the appropriate 
-number of sectors is read, the drive is stopped by a ACDM_STOP command. This
-does not work with the Aztech drive. I did not find a way to stop it. The
-stop and pause commands do only work in AUDIO mode but not in DATA mode.
-Therefore I had to modify the 'finite state machine' in function azt_poll to
-only read a certain number of sectors and then start a new read on demand. As I 
-have not completely understood, how the buffer/caching scheme of the Mitsumi 
-driver was implemented, I am not sure, if I have covered all cases correctly, 
-whenever you get timeout messages, the bug is most likely to be in that
-function azt_poll() around switch(cmd) .... case ACD_S_DATA. 
-
-d) I did not get information about changing drive mode. So I doubt, that the
-code around function azt_poll() case AZT_S_MODE does work. In my test I have
-not been able to switch to reading in raw mode. For reading raw mode, Aztech
-uses a different command than for cooked mode, which I only have implemen-
-ted in the ioctl-section but not in the section which is used by the ISO9660. 
-
-The driver was developed on an AST PC with Intel 486/DX2, 8MB RAM, 340MB IDE 
-hard disk and on an AST PC with Intel Pentium 60MHz, 16MB RAM, 520MB IDE 
-running Linux kernel version 1.0.9 from the LST 1.8 Distribution. The kernel 
-was compiled with gcc.2.5.8. My CD-ROM drive is an Aztech CDA268-01A. My
-drive says, that it has Firmware Version AZT26801A1.3. It came with an ISA-bus
-interface card and works with polled I/O without DMA and without interrupts.
-The code for all other drives was 'remote' tested and debugged by a number of 
-volunteers on the Internet.
-
-Points, where I feel that possible problems might be and all points where I 
-did not completely understand the drive's behaviour or trust my own code are 
-marked with /*???*/ in the source code. There are also some parts in the 
-Mitsumi driver, where I did not completely understand their code.

-10. ACKNOWLEDGMENTS
-Without the help of P.Bush, Aztech, who delivered technical information
-about the Aztech Drive and without the help of E.Moenkeberg, GWDG, who did a
-great job in analyzing the command structure of various CD-ROM drives, this
-work would not have been possible. E.Moenkeberg was also a great help in 
-making the software 'kernel ready' and in answering many of the CDROM-related 
-questions in the newsgroups. He really is *the* Linux CD-ROM guru. Thanks 
-also to all the guys on the Internet, who collected valuable technical 
-information about CDROMs. 
-
-Joe Nardone (joe@access.digex.net) was a patient tester even for my first
-trial, which was more than slow, and made suggestions for code improvement.
-Especially the 'finite state machine' azt_poll() was rewritten by Joe to get
-clean C code and avoid the ugly 'gotos', which I copied from mcd.c.
-
-Robby Schirmer (schirmer@fmi.uni-passau.de) tested the audio stuff (ioctls) 
-and suggested a lot of patches for them.
-
-Joseph Piskor and Peter Nugent were the first users with the ORCHID CD3110
-and also were very patient with the problems which occurred.
-
-Reinhard Max delivered the information for the CDROM-interface of the
-SoundWave32 soundcards.
-
-Jochen Kunz and Olaf Kaluza delivered the information for supporting Conrad's 
-TXC drive.
-
-Hilmar Berger delivered the patches for supporting CyCDROM CR520ie.

-11. PROGRAMMING ADD ONs: cdplay.c
-You can use the ioctl-functions included in aztcd.c in your own programs. As
-an example on how to do this, you will find a tiny CD Player for audio CDs 
-named 'cdplay.c'. It allows you to play audio CDs. You can play a specified 
-track, pause and resume or skip tracks forward and backwards. If you quit the 
-program without stopping the  drive, playing is continued. You can also 
-(mis)use cdplay to read and hexdump data disks. You can find the code in the 
-APPENDIX of this file, which you should cut out with an editor and store in a 
-separate file 'cdplay.c'. To compile it and make it executable, do
-  gcc -s -Wall -O2 -L/usr/lib cdplay.c -o /usr/local/bin/cdplay # compiles it
-  chmod +755 /usr/local/bin/cdplay                              # makes it executable
-  ln -s /dev/aztcd0 /dev/cdrom                                  # creates a link
-   (for /usr/lib substitute the top level directory, where your include files 
-    reside,  and for /usr/local/bin the directory, where you want the executable 
-    binary to reside )
-
-You have to set the correct permissions for cdplay *and* for /dev/mcd0 or
-/dev/aztcd0 in order to use it. Remember, that you should not have /dev/cdrom 
-mounted, when you're playing audio CDs. 
-
-This program is just a hack for testing the ioctl-functions in aztcd.c. I will 
-not maintain it, so if you run into problems, discard it or have a look into 
-the source code 'cdplay.c'. The program does only contain a minimum of user 
-protection and input error detection. If you use the commands in the wrong 
-order or if you try to read a CD at wrong addresses, you may get error messages
-or even hang your machine. If you get STEN_LOW, STEN_LOW_WAIT or segment violation 
-error messages when using cdplay, after that, the system might not be stable 
-any more, so you'd better reboot. As the ioctl-functions run in kernel mode,
-most normal Linux-multitasking protection features do not work. By using
-uninitialized 'wild' pointers etc., it is easy to write to other users' data 
-and program areas, destroy kernel tables etc.. So if you experiment with ioctls
-as always when you are doing systems programming and kernel hacking, you
-should have a backup copy of your system in a safe place (and you also
-should try restoring from a backup copy first)!
-
-A reworked and improved version called 'cdtester.c', which has yet more
-features for testing CDROM-drives can be found in
-Documentation/cdrom/sbpcd, written by E.Moenkeberg.

-		CDU31A/CDU33A Driver Info
-		-------------------------
-
-Information on the Sony CDU31A/CDU33A CDROM driver for the Linux
-kernel.

-  Driver Special Features
-
-  
-This device driver handles Sony CDU31A/CDU33A CDROM drives and
-provides a complete block-level interface as well as an ioctl()
-interface as specified in include/linux/cdrom.h).  With this
-interface, CDROMs can be accessed, standard audio CDs can be played
-back normally, and CD audio information can be read off the drive.
-
-Note that this will only work for CDU31A/CDU33A drives.  Some vendors
-market their drives as CDU31A compatible.  They lie.  Their drives are
-really CDU31A hardware interface compatible (they can plug into the
-same card).  They are not software compatible.
-
-Setting Up the Hardware
------------------------
-
-The CDU31A driver is unable to safely tell if an interface card is
-present that it can use because the interface card does not announce
-its presence in any way besides placing 4 I/O locations in memory.  It
-used to just probe memory and attempt commands, but Linus wisely asked
-me to remove that because it could really screw up other hardware in
-the system.
-
-Because of this, you must tell the kernel where the drive interface
-is, what interrupts are used, and possibly if you are on a PAS-16
-soundcard.
-
-If you have the Sony CDU31A/CDU33A drive interface card, the following
-diagram will help you set it up.  If you have another card, you are on
-your own.  You need to make sure that the I/O address and interrupt is
-not used by another card in the system.  You will need to know the I/O
-address and interrupt you have set.  Note that use of interrupts is
-highly recommended, if possible, it really cuts down on CPU used.
-Unfortunately, most soundcards do not support interrupts for their
-CDROM interfaces.  By default, the Sony interface card comes with
-interrupts disabled.

-   
-                  The documentation states to set this for interrupt
-                  4, but I think that is a mistake.
-
-Note that if you have another interface card, you will need to look at
-the documentation to find the I/O base address.  This is specified to
-the SLCD.SYS driver for DOS with the /B: parameter, so you can look at
-you DOS driver setup to find the address, if necessary.
-
-Configuring the Kernel
-----------------------
-
-You must tell the kernel where the drive is at boot time.  This can be
-done at the Linux boot prompt, by using LILO, or by using Bootlin.
-Note that this is no substitute for HOWTOs and LILO documentation, if
-you are confused please read those for info on bootline configuration
-and LILO.
-
-At the linux boot prompt, press the ALT key and add the following line
-after the boot name (you can let the kernel boot, it will tell you the
-default boot name while booting):
-
-	cdu31a=<base address>,<interrupt>[,PAS]
-
-The base address needs to have "0x" in front of it, since it is in
-hex.  For instance, to configure a drive at address 320 on interrupt 5,
-use the following:
-
-	cdu31a=0x320,5
-
-I use the following boot line:
-
-	cdu31a=0x1f88,0,PAS
-
-because I have a PAS-16 which does not support interrupt for the
-CDU31A interface.
-
-Adding this as an append line at the beginning of the /etc/lilo.conf
-file will set it for lilo configurations.  I have the following as the
-first line in my lilo.conf file:
-
-	append="cdu31a=0x1f88,0"
-
-I'm not sure how to set up Bootlin (I have never used it), if someone
-would like to fill in this section please do.
-
-
-Configuring as a Module
------------------------
-
-The driver supports loading as a module.  However, you must specify
-the boot address and interrupt on the boot line to insmod.  You can't
-use modprobe to load it, since modprobe doesn't support setting
-variables.
-
-Anyway, I use the following line to load my driver as a module
-
-  /sbin/insmod /lib/modules/`uname -r`/misc/cdu31a.o cdu31a_port=0x1f88
-
-You can set the following variables in the driver:
-
-  cdu31a_port=<I/O address> - sets the base I/O.  If hex, put 0x in
-			      front of it.  This must be specified.
-
-  cdu31a_irq=<interrupt> - Sets the interrupt number.  Leaving this
-			   off will turn interrupts off.
-
-
-Driver Special Features
------------------------
-
-This section describes features beyond the normal audio and CD-ROM
-functions of the drive.
-
-2048 byte buffer mode
-
-If a disk is mounted with -o block=2048, data is copied straight from
-the drive data port to the buffer.  Otherwise, the readahead buffer
-must be involved to hold the other 1K of data when a 1K block
-operation is done.  Note that with 2048 byte blocks you cannot execute
-files from the CD.
-
-XA compatibility
-
-The driver should support XA disks for both the CDU31A and CDU33A.  It
-does this transparently, the using program doesn't need to set it.
-
-Multi-Session
-
-A multi-session disk looks just like a normal disk to the user.  Just
-mount one normally, and all the data should be there.  A special
-thanks to Koen for help with this!
-
-Raw sector I/O
-
-Using the CDROMREADAUDIO it is possible to read raw audio and data
-tracks.  Both operations return 2352 bytes per sector.  On the data
-tracks, the first 12 bytes is not returned by the drive and the value
-of that data is indeterminate.

-This is the readme file for the driver for the Philips/LMS cdrom drive
-cm206 in combination with the cm260 host adapter card. 
-
-				(c) 1995 David A. van Leeuwen
-   
-Changes since version 0.99
---------------------------
-- Interfacing to the kernel is routed though an extra interface layer, 
-  cdrom.c. This allows runtime-configurable `behavior' of the cdrom-drive, 
-  independent of the driver. 
-
-Features since version 0.33
----------------------------
-- Full audio support, that is, both  workman, workbone and cdp work
-  now reasonably. Reading TOC still takes some time. xmcd has been
-  reported to run successfully. 
-- Made auto-probe code a little better, I hope
-
-Features since version 0.28
----------------------------
-- Full speed transfer rate (300 kB/s).
-- Minimum kernel memory usage for buffering (less than 3 kB).
-- Multisession support.
-- Tray locking.
-- Statistics of driver accessible to the user.
-- Module support.
-- Auto-probing of adapter card's base port and irq line,
-  also configurable at boot time or module load time.
-
-
-Decide how you are going to use the driver. There are two
-options:
-
-   (a) installing the driver as a resident part of the kernel
-   (b) compiling the driver as a loadable module
-
-   Further, you must decide if you are going to specify the base port
-   address and the interrupt request line of the adapter card cm260 as
-   boot options for (a), module parameters for (b), use automatic
-   probing of these values, or hard-wire your adaptor card's settings
-   into the source code. If you don't care, you can choose 
-   autoprobing, which is the default. In that case you can move on to
-   the next step.
-
-Compiling the kernel
---------------------
-1) move to /usr/src/linux and do a 
-
-	make config
-
-   If you have chosen option (a), answer yes to CONFIG_CM206 and
-   CONFIG_ISO9660_FS.
-
-   If you have chosen option (b), answer yes to CONFIG_MODVERSIONS
-   and no (!) to CONFIG_CM206 and CONFIG_ISO9660_FS. 
-
-2) then do a 
-	
-	make clean; make zImage; make modules
-
-3) do the usual things to install a new image (backup the old one, run
-   `rdev -R zImage 1', copy the new image in place, run lilo).  Might
-   be `make zlilo'.
-
-Using the driver as a module
-----------------------------
-If you will only occasionally use the cd-rom driver, you can choose
-option (b), install as a loadable module. You may have to re-compile
-the module when you upgrade the kernel to a new version. 
-
-Since version 0.96, much of the functionality has been transferred to
-a generic cdrom interface in the file cdrom.c. The module cm206.o
-depends on cdrom.o. If the latter is not compiled into the kernel,
-you must explicitly load it before cm206.o:
-
-	 insmod /usr/src/linux/modules/cdrom.o
-
-To install the module, you use the command, as root
-
-	insmod /usr/src/linux/modules/cm206.o
-
-You can specify the base address on the command line as well as the irq 
-line to be used, e.g.
-
-	insmod /usr/src/linux/modules/cm206.o cm206=0x300,11
-
-The order of base port and irq line doesn't matter; if you specify only
-one, the other will have the value of the compiled-in default.  You
-may also have to install the file-system module `iso9660.o', if you
-didn't compile that into the kernel. 
-
-
-Using the driver as part of the kernel
---------------------------------------
-If you have chosen option (a), you can specify the base-port
-address and irq on the lilo boot command line, e.g.:
-
-	LILO: linux cm206=0x340,11
-
-This assumes that your linux kernel image keyword is `linux'. 
-If you specify either IRQ (3--11) or base port (0x300--0x370),
-auto probing is turned off for both settings, thus setting the 
-other value to the compiled-in default.
-
-Note that you can also put these parameters in the lilo configuration file:
-
-# linux config
-image = /vmlinuz
-   root = /dev/hda1
-   label = Linux
-   append = "cm206=0x340,11"
-   read-only
-
-
-If module parameters and LILO config options don't work
--------------------------------------------------------
-If autoprobing does not work, you can hard-wire the default values
-of the base port address (CM206_BASE) and interrupt request line
-(CM206_IRQ) into the file /usr/src/linux/drivers/cdrom/cm206.h. Change
-the defines of CM206_IRQ and CM206_BASE.
-
-
-Mounting the cdrom
-------------------
-1) Make sure that the right device is installed in /dev.
-
-  	mknod /dev/cm206cd b 32 0
-
-2) Make sure there is a mount point, e.g., /cdrom 
-
-	mkdir /cdrom
-
-3) mount using a command like this (run as root):
-
-	mount -rt iso9660 /dev/cm206cd /cdrom
-
-4) For user-mounts, add a line in /etc/fstab
-
-	/dev/cm206cd      /cdrom     iso9660 	ro,noauto,user
-
-   This will allow users to give the commands
-
-	mount /cdrom
-	umount /cdrom
-
-If things don't work
---------------------
-
-- Try to do a `dmesg' to find out if the driver said anything about
-  what is going wrong during the initialization.
-
-- Try to do a `dd if=/dev/cm206cd | od -tc | less' to read from the
-  CD.
-
-- Look in the /proc directory to see if `cm206' shows up under one of
-  `interrupts', `ioports', `devices' or `modules' (if applicable).
-

----------- 
-I cannot guarantee that this driver works, or that the hardware will
-not be harmed, although I consider it most unlikely.

-	Goldstar R420 CD-Rom device driver README
-
-For all kind of other information about the GoldStar R420 CDROM
-and this Linux device driver see the WWW page:
-
-        http://linux.rz.fh-hannover.de/~raupach        
-
-
-      If you are the editor of a Linux CD, you should
-      enable gscd.c within your boot floppy kernel. Please,
-      send me one of your CDs for free.
-
-
-This current driver version 0.4a only supports reading data from the disk.
-Currently we have no audio and no multisession or XA support.
-The polling interface is used, no DMA.
-
-
-Sometimes the GoldStar R420 is sold in a 'Reveal Multimedia Kit'. This kit's
-drive interface is compatible, too.
-
-
-Installation
-------------
-
-Change to '/usr/src/linux/drivers/cdrom' and edit the file 'gscd.h'. Insert
-the i/o address of your interface card.
-
-The default base address is 0x340. This will work for most applications. 
-Address selection is accomplished by jumpers PN801-1 to PN801-4 on the 
-GoldStar Interface Card.
-Appropriate settings are: 0x300, 0x310, 0x320, 0x330, 0x340, 0x350, 0x360
-0x370, 0x380, 0x390, 0x3A0, 0x3B0, 0x3C0, 0x3D0, 0x3E0, 0x3F0             
-
-Then go back to '/usr/src/linux/' and 'make config' to build the new
-configuration for your kernel. If you want to use the GoldStar driver
-like a module, don't select 'GoldStar CDROM support'. By the way, you
-have to include the iso9660 filesystem.
-
-Now start compiling the kernel with 'make zImage'.
-If you want to use the driver as a module, you have to do 'make modules' 
-and 'make modules_install', additionally.
-Install your new kernel as usual - maybe you do it with 'make zlilo'.
-
-Before you can use the driver, you have to
-   mknod /dev/gscd0 b 16 0
-to create the appropriate device file (you only need to do this once).
-
-If you use modules, you can try to insert the driver.
-Say: 'insmod /usr/src/linux/modules/gscd.o'
-or:  'insmod /usr/src/linux/modules/gscd.o gscd=<address>'
-The driver should report its results.
-
-That's it! Mount a disk, i.e. 'mount -rt iso9660 /dev/gscd0 /cdrom'
-
-Feel free to report errors and suggestions to the following address.
-Be sure, I'm very happy to receive your comments!

-Docs by Eric van der Maarel <H.T.M.v.d.Maarel@marin.nl>
-
-This is the README for version 0.6 of the cdrom interface on an
-ISP16, MAD16 or Mozart sound card.
-
-The detection and configuration of this interface used to be included
-in both the sjcd and optcd cdrom driver. Drives supported by these
-drivers came packed with Media Magic's multi media kit, which also
-included the ISP16 card. The idea (thanks Leo Spiekman)
-to move it from these drivers into a separate module and moreover, not to
-rely on the MAD16 sound driver, are as follows:
--duplication of code in the kernel is a waste of resources and should
- be avoided;
--however, kernels and notably those included with Linux distributions
- (cf Slackware 3.0 included version 0.5 of the isp16 configuration
- code included in the drivers) don't always come with sound support
- included. Especially when they already include a bunch of cdrom drivers.
- Hence, the cdrom interface should be configurable _independently_ of
- sound support.
-
-The ISP16, MAD16 and Mozart sound cards have an OPTi 82C928 or an
-OPTi 82C929 chip.  The interface on these cards should work with
-any cdrom attached to the card, which is 'electrically' compatible
-with Sanyo/Panasonic, Sony or Mitsumi non-ide drives. However, the
-command sets for any proprietary drives may differ
-(and hence may not be supported in the kernel) from these four types.
-For a fact I know the interface works and the way of configuration
-as described in this documentation works in combination with the
-sjcd (in Sanyo/Panasonic compatibility mode) cdrom drivers
-(probably with the optcd (in Sony compatibility mode) as well).
-If you have such an OPTi based sound card and you want to use the
-cdrom interface with a cdrom drive supported by any of the other cdrom
-drivers, it will probably work. Please let me know any experience you
-might have).
-I understand that cards based on the OPTi 82C929 chips may be configured
-(hardware jumpers that is) as an IDE interface. Initialisation of such a
-card in this mode is not supported (yet?).
-
-The suggestion to configure the ISP16 etc. sound card by booting DOS and 
-do a warm reboot to boot Linux somehow doesn't work, at least not
-on my machine (IPC P90), with the OPTi 82C928 based card.
-
-Booting the kernel through the boot manager LILO allows the use
-of some command line options on the 'LILO boot:' prompt. At boot time
-press Alt or Shift while the LILO prompt is written on the screen and enter
-any kernel options. Alternatively these options may be used in
-the appropriate section in /etc/lilo.conf. Adding 'append="<cmd_line_options>"'
-will do the trick as well.
-The syntax of 'cmd_line_options' is
-
-        isp16=[<port>[,<irq>[,<dma>]]][[,]<drive_type>]
-
-If there is no ISP16 or compatibles detected, there's probably no harm done.
-These options indicate the values that your cdrom drive has been (or will be)
-configured to use.
-Valid values for the base i/o address are:
-  port=0x340,0x320,0x330,0x360
-for the interrupt request number 
-  irq=0,3,5,7,9,10,11
-for the direct memory access line
-  dma=0,3,5,6,7
-and for the type of drive
-  drive_type=noisp16,Sanyo,Panasonic,Sony,Mitsumi.
-Note that these options are case sensitive.
-The values 0 for irq and dma indicate that they are not used, and
-the drive will be used in 'polling' mode. The values 5 and 7 for irq
-should be avoided in order to avoid any conflicts with optional
-sound card configuration.
-The syntax of the command line does not allow the specification of
-irq when there's nothing specified for the base address and no
-specification of dma when there is no specification of irq.
-The value 'noisp16' for drive_type, which may be used as the first
-non-integer option value (e.g. 'isp16=noisp16'), makes sure that probing
-for and subsequent configuration of an ISP16-compatible card is skipped
-all together. This can be useful to overcome possible conflicts which
-may arise while the kernel is probing your hardware.
-The default values are
-  port=0x340
-  irq=0
-  dma=0
-  drive_type=Sanyo
-reflecting my own configuration. The defaults can be changed in
-the file linux/drivers/cdrom/ips16.h.
-
-The cdrom interface can be configured at run time by loading the
-initialisation driver as a module. In that case, the interface
-parameters can be set by giving appropriate values on the command
-line. Configuring the driver can then be done by the following
-command (assuming you have iso16.o installed in a proper place):
-
-  insmod isp16.o isp16_cdrom_base=<port> isp16_cdrom_irq=<irq> \
-    isp16_cdrom_dma=<dma> isp16_cdrom_type=<drive_type>
-
-where port, irq, dma and drive_type can have any of the values mentioned
-above.
-
-
-Have fun!

-This is the README file for the Optics Storage 8000 AT CDROM device driver.
-
-This is the driver for the so-called 'DOLPHIN' drive, with the 34-pin
-Sony-compatible interface. For the IDE-compatible Optics Storage 8001
-drive, you will want the ATAPI CDROM driver. The driver also seems to
-work with the Lasermate CR328A. If you have a drive that works with
-this driver, and that doesn't report itself as DOLPHIN, please drop me
-a mail.
-
-The support for multisession CDs is in ALPHA stage. If you use it,
-please mail me your experiences. Multisession support can be disabled
-at compile time.
-
-You can find some older versions of the driver at
-      dutette.et.tudelft.nl:/pub/linux/
-and at Eberhard's mirror
-      ftp.gwdg.de:/pub/linux/cdrom/drivers/optics/
-
-Before you can use the driver, you have to create the device file once:
- # mknod /dev/optcd0 b 17 0
-
-To specify the base address if the driver is "compiled-in" to your kernel,
-you can use the kernel command line item (LILO option)
-             optcd=0x340
-with the right address.
-
-If you have compiled optcd as a module, you can load it with
- # insmod /usr/src/linux/modules/optcd.o
-or
- # insmod /usr/src/linux/modules/optcd.o optcd=0x340
-with the matching address value of your interface card.
-
-The driver employs a number of buffers to do read-ahead and block size
-conversion. The number of buffers is configurable in optcd.h, and has
-influence on the driver performance. For my machine (a P75), 6 buffers
-seems optimal, as can be seen from this table:
-
-#bufs	kb/s	%cpu
-1	97	0.1
-2	191	0.3
-3	188	0.2
-4	246	0.3
-5	189	19
-6	280	0.4
-7	281	7.0
-8	246	2.8
-16	281	3.4
-
-If you get a throughput significantly below 300 kb/s, try tweaking
-N_BUFS, and don't forget to mail me your results!
-
-I'd appreciate success/failure reports. If you find a bug, try
-recompiling the driver with some strategically chosen debug options
-(these can be found in optcd.h) and include the messages generated in
-your bug report. Good luck.

-The driver is able to drive the whole family of "traditional" AT-style (that
-is NOT the new "Enhanced IDE" or "ATAPI" drive standard) Matsushita,
-Kotobuki, Panasonic drives, sometimes labelled as "CreativeLabs". The
-well-known drives are CR-521, CR-522, CR-523, CR-562, CR-563.
-CR-574 is an IDE/ATAPI drive.
-
-The Longshine LCS-7260 is a double-speed drive which uses the "old"
-Matsushita command set. It is supported - with help by Serge Robyns.
-Vertos ("Elitegroup Computer Systems", ECS) has a similar drive - support
-has started; get in contact if you have such a "Vertos 100" or "ECS-AT"
-drive.
-
-There exists an "IBM External ISA CD-ROM Drive" which in fact is a CR-563
-with a special controller board. This drive is supported (the interface is
-of the "LaserMate" type), and it is possibly the best buy today (cheaper than
-an internal drive, and you can use it as an internal, too - e.g. plug it into
-a soundcard).
-
-CreativeLabs has a new drive "CD200" and a similar drive "CD200F". The latter
-is made by Funai and sometimes named "E2550UA", newer models may be named
-"MK4015". The CD200F drives should fully work.
-CD200 drives without "F" are still giving problems: drive detection and
-playing audio should work, data access will result in errors. I need qualified
-feedback about the bugs within the data functions or a drive (I never saw a
-CD200).
-
-The quad-speed Teac CD-55A drive is supported, but still does not reach "full
-speed". The data rate already reaches 500 kB/sec if you set SBP_BUFFER_FRAMES
-to 64 (it is not recommended to do that for normal "file access" usage, but it
-can speed up things a lot if you use something like "dd" to read from the
-drive; I use it for verifying self-written CDs this way).
-The drive itself is able to deliver 600 kB/sec, so this needs
-work; with the normal setup, the performance currently is not even as good as
-double-speed.
-
-This driver is NOT for Mitsumi or Sony or Aztech or Philips or XXX drives,
-and again: this driver is in no way usable for any IDE/ATAPI drive. If you 
-think your drive should work and it doesn't: send me the DOS driver for your
-beast (gzipped + uuencoded) and your CONFIG.SYS if you want to ask me for help,
-and include an original log message excerpt, and try to give all information
-a complete idiot needs to understand your hassle already with your first
-mail. And if you want to say "as I have mailed you before", be sure that I
-don't remember your "case" by such remarks; at the moment, I have some 
-hundreds of open correspondences about Linux CDROM questions (hope to reduce if
-the IDE/ATAPI user questions disappear). 
-
-
-This driver will work with the soundcard interfaces (SB Pro, SB 16, Galaxy,
-SoundFX, Mozart, MAD16 ...) and with the "no-sound" cards (Panasonic CI-101P,
-LaserMate, WDH-7001C, Longshine LCS-6853, Teac ...).
-
-It works with the "configurable" interface "Sequoia S-1000", too, which is 
-used on the Spea Media FX and Ensonic Soundscape sound cards. You have to
-specify the type "SBPRO 2" and the true CDROM port address with it, not the
-"configuration port" address.
-
-If you have a sound card which needs a "configuration driver" instead of
-jumpers for interface types and addresses (like Mozart cards) - those
-drivers get invoked before the DOS CDROM driver in your CONFIG.SYS, typical
-names are "cdsetup.sys" and "mztinit.sys" - let the sound driver do the
-CDROM port configuration (the leading comments in linux/drivers/sound/mad16.c
-are just for you!). Hannu Savolainen's mad16.c code is able to set up my
-Mozart card - I simply had to add
-   #define MAD16_CONF 0x06
-   #define MAD16_CDSEL 0x03
-to configure the CDROM interface for type "Panasonic" (LaserMate) and address
-0x340.
-
-The interface type has to get configured in linux/drivers/cdrom/sbpcd.h, 
-because the register layout is different between the "SoundBlaster" and the
-"LaserMate" type.
-
-I got a report that the Teac interface card "I/F E117098" is of type
-"SoundBlaster" (i.e. you have to set SBPRO to 1) even with the addresses
-0x300 and above. This is unusual, and it can't get covered by the auto
-probing scheme.
-The Teac 16-bit interface cards (like P/N E950228-00A, default address 0x2C0)
-need the SBPRO 3 setup.
-
-If auto-probing found the drive, the address is correct. The reported type
-may be wrong. A "mount" will give success only if the interface type is set
-right. Playing audio should work with a wrong set interface type, too.
-
-With some Teac and some CD200 drives I have seen interface cards which seem
-to lack the "drive select" lines; always drive 0 gets addressed. To avoid
-"mirror drives" (four drives detected where you only have one) with such
-interface cards, set MAX_DRIVES to 1 and jumper your drive to ID 0 (if
-possible).
-
-
-Up to 4 drives per interface card, and up to 4 interface cards are supported.
-All supported drive families can be mixed, but the CR-521 drives are 
-hard-wired to drive ID 0. The drives have to use different drive IDs, and each
-drive has to get a unique minor number (0...3), corresponding indirectly to 
-its drive ID.
-The drive IDs may be selected freely from 0 to 3 - they do not have to be in
-consecutive order.
-
-As Don Carroll, don@ds9.us.dell.com or FIDO 1:382/14, told me, it is possible
-to change old drives to any ID, too. He writes in this sense:
-   "In order to be able to use more than one single speed drive
-   (they do not have the ID jumpers) you must add a DIP switch
-   and two resistors. The pads are already on the board next to
-   the power connector. You will see the silkscreen for the
-   switch if you remove the top cover.
-                    1 2 3 4
-             ID 0 = x F F x             O = "on"
-             ID 1 = x O F x             F = "off"
-             ID 2 = x F O x             x = "don't care"
-             ID 3 = x O O x
-   Next to the switch are the positions for R76 (7k) and R78
-   (12k). I had to play around with the resistor values - ID 3
-   did not work with other values. If the values are not good,
-   ID 3 behaves like ID 0."
-
-To use more than 4 drives, you simply need a second controller card at a 
-different address and a second cable.
-
-The driver supports reading of data from the CD and playing of audio tracks.
-The audio part should run with WorkMan, xcdplayer, with the "non-X11" products
-CDplayer and WorkBone - tell me if it is not compatible with other software.
-The only accepted measure for correctness with the audio functions is the
-"cdtester" utility (appended) - most audio player programmers seem to be
-better musicians than programmers. ;-)
-
-With the CR-56x and the CD200 drives, the reading of audio frames is possible.
-This is implemented by an IOCTL function which reads READ_AUDIO frames of
-2352 bytes at once (configurable with the "READ_AUDIO" define, default is 0).
-Reading the same frame a second time gives different data; the frame data 
-start at a different position, but all read bytes are valid, and we always
-read 98 consecutive chunks (of 24 Bytes) as a frame. Reading more than 1 frame
-at once possibly misses some chunks at each frame boundary. This lack has to
-get corrected by external, "higher level" software which reads the same frame 
-again and tries to find and eliminate overlapping chunks (24-byte-pieces).
-
-The transfer rate with reading audio (1-frame-pieces) currently is very slow.
-This can be better reading bigger chunks, but the "missing" chunks possibly
-occur at the beginning of each single frame.
-The software interface possibly may change a bit the day the SCSI driver
-supports it too.
-
-With all but the CR-52x drives, MultiSession is supported.
-Photo CDs work (the "old" drives like CR-521 can access only the first
-session of a photoCD).
-At ftp.gwdg.de:/pub/linux/hpcdtoppm/ you will find Hadmut Danisch's package to
-convert photo CD image files and Gerd Knorr's viewing utility.
-
-The transfer rate will reach 150 kB/sec with CR-52x drives, 300 kB/sec with
-CR-56x drives, and currently not more than 500 kB/sec (usually less than
-250 kB/sec) with the Teac quad speed drives.
-XA (PhotoCD) disks with "old" drives give only 50 kB/sec.

-
-
-To install:
------------
-
-1. Setup your hardware parameters. Though the driver does "auto-probing" at a
-   lot of (not all possible!) addresses, this step is recommended for
-   everyday use. You should let sbpcd auto-probe once and use the reported
-   address if a drive got found. The reported type may be incorrect; it is
-   correct if you can mount a data CD. There is no choice for you with the
-   type; only one is right, the others are deadly wrong.
-
-   a. Go into /usr/src/linux/drivers/cdrom/sbpcd.h and configure it for your
-      hardware (near the beginning):
-      a1. Set it up for the appropriate type of interface board.
-          "Original" CreativeLabs sound cards need "SBPRO 1".
-          Most "compatible" sound cards (almost all "non-CreativeLabs" cards)
-          need "SBPRO 0".
-          The "no-sound" board from OmniCd needs the "SBPRO 1" setup.
-          The Teac 8-bit "no-sound" boards need the "SBPRO 1" setup.
-          The Teac 16-bit "no-sound" boards need the "SBPRO 3" setup.
-          All other "no-sound" boards need the "SBPRO 0" setup.
-          The Spea Media FX and Ensoniq SoundScape cards need "SBPRO 2".
-          sbpcd.c holds some examples in its auto-probe list.
-          If you configure "SBPRO" wrong, the playing of audio CDs will work,
-          but you will not be able to mount a data CD.
-      a2. Tell the address of your CDROM_PORT (not of the sound port).
-      a3. If 4 drives get found, but you have only one, set MAX_DRIVES to 1.
-      a4. Set DISTRIBUTION to 0.
-   b. Additionally for 2.a1 and 2.a2, the setup may be done during
-      boot time (via the "kernel command line" or "LILO option"):
-          sbpcd=0x320,LaserMate
-      or
-          sbpcd=0x230,SoundBlaster
-      or
-          sbpcd=0x338,SoundScape
-      or
-          sbpcd=0x2C0,Teac16bit
-      This is especially useful if you install a fresh distribution.
-      If the second parameter is a number, it gets taken as the type
-      setting; 0 is "LaserMate", 1 is "SoundBlaster", 2 is "SoundScape",
-      3 is "Teac16bit".
-      So, for example
-          sbpcd=0x230,1
-      is equivalent to
-          sbpcd=0x230,SoundBlaster
-
-2. "cd /usr/src/linux" and do a "make config" and select "y" for Matsushita
-   CD-ROM support and for ISO9660 FileSystem support. If you do not have a
-   second, third, or fourth controller installed, do not say "y" to the 
-   secondary Matsushita CD-ROM questions.
-
-3. Then make the kernel image ("make zlilo" or similar).
-
-4. Make the device file(s). This step usually already has been done by the
-   MAKEDEV script.
-   The driver uses MAJOR 25, so, if necessary, do
-        mknod /dev/sbpcd  b 25 0       (if you have only one drive)
-   and/or
-        mknod /dev/sbpcd0 b 25 0
-        mknod /dev/sbpcd1 b 25 1
-        mknod /dev/sbpcd2 b 25 2
-        mknod /dev/sbpcd3 b 25 3
-   to make the node(s).
-
-   The "first found" drive gets MINOR 0 (regardless of its jumpered ID), the
-   "next found" (at the same cable) gets MINOR 1, ...
-   
-   For a second interface board, you have to make nodes like
-        mknod /dev/sbpcd4 b 26 0
-        mknod /dev/sbpcd5 b 26 1
-   and so on. Use the MAJORs 26, 27, 28.
-
-   If you further make a link like
-        ln -s sbpcd /dev/cdrom
-   you can use the name /dev/cdrom, too.
-
-5. Reboot with the new kernel.
-
-You should now be able to do
-              mkdir /CD
-and 
-              mount -rt iso9660 /dev/sbpcd /CD
-or
-              mount -rt iso9660 -o block=2048 /dev/sbpcd /CD
-and see the contents of your CD in the /CD directory.
-To use audio CDs, a mounting is not recommended (and it would fail if the
-first track is not a data track).
-
-
-Using sbpcd as a "loadable module":
------------------------------------
-
-If you do NOT select "Matsushita/Panasonic CDROM driver support" during the
-"make config" of your kernel, you can build the "loadable module" sbpcd.o.
-
-If sbpcd gets used as a module, the support of more than one interface
-card (i.e. drives 4...15) is disabled.
-
-You can specify interface address and type with the "insmod" command like:
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x340,0
-or
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x230,1
-or
- # insmod /usr/src/linux/modules/sbpcd.o sbpcd=0x338,2
-where the last number represents the SBPRO setting (no strings allowed here).
-
-
-Things of interest:
--------------------
-
-The driver is configured to try the LaserMate type of interface at I/O port
-0x0340 first. If this is not appropriate, sbpcd.h should get changed
-(you will find the right place - just at the beginning).
-
-No DMA and no IRQ is used.
-
-To reduce or increase the amount of kernel messages, edit sbpcd.c and play
-with the "DBG_xxx" switches (initialization of the variable "sbpcd_debug").
-Don't forget to reflect on what you do; enabling all DBG_xxx switches at once
-may crash your system, and each message line is accompanied by a delay.
-
-The driver uses the "variable BLOCK_SIZE" feature. To use it, you have to
-specify "block=2048" as a mount option. Doing this will disable the direct
-execution of a binary from the CD; you have to copy it to a device with the
-standard BLOCK_SIZE (1024) first. So, do not use this if your system is
-directly "running from the CDROM" (like some of Yggdrasil's installation
-variants). There are CDs on the market (like the German "unifix" Linux
-distribution) which MUST get handled with a block_size of 1024. Generally,
-one can say all the CDs which hold files of the name YMTRANS.TBL are defective;
-do not use block=2048 with those.
-
-Within sbpcd.h, you will find some "#define"s (e.g. EJECT and JUKEBOX). With
-these, you can configure the driver for some special things.
-You can use the appended program "cdtester" to set the auto-eject feature
-during runtime. Jeff Tranter's "eject" utility can do this, too (and more)
-for you.
-
-There is an ioctl CDROMMULTISESSION to obtain with a user program if
-the CD is an XA disk and - if it is - where the last session starts. The
-"cdtester" program illustrates how to call it.
-
-
-Auto-probing at boot time:
---------------------------
-
-The driver does auto-probing at many well-known interface card addresses,
-but not all:
-Some probings can cause a hang if an NE2000 ethernet card gets touched, because
-SBPCD's auto-probing happens before the initialization of the net drivers.
-Those "hazardous" addresses are excluded from auto-probing; the "kernel 
-command line" feature has to be used during installation if you have your 
-drive at those addresses. The "module" version is allowed to probe at those
-addresses, too.
-
-The auto-probing looks first at the configured address resp. the address
-submitted by the kernel command line. With this, it is possible to use this
-driver within installation boot floppies, and for any non-standard address,
-too.
-
-Auto-probing will make an assumption about the interface type ("SBPRO" or not),
-based upon the address. That assumption may be wrong (initialization will be
-o.k., but you will get I/O errors during mount). In that case, use the "kernel
-command line" feature and specify address & type at boot time to find out the
-right setup.
-
-For everyday use, address and type should get configured within sbpcd.h. That
-will stop the auto-probing due to success with the first try.
-
-The kernel command "sbpcd=0" suppresses each auto-probing and causes
-the driver not to find any drive; it is meant for people who love sbpcd
-so much that they do not want to miss it, even if they miss the drives. ;-)  
-
-If you configure "#define CDROM_PORT 0" in sbpcd.h, the auto-probing is
-initially disabled and needs an explicit kernel command to get activated.
-Once activated, it does not stop before success or end-of-list. This may be
-useful within "universal" CDROM installation boot floppies (but using the 
-loadable module would be better because it allows an "extended" auto-probing
-without fearing NE2000 cards).
-
-To shorten the auto-probing list to a single entry, set DISTRIBUTION 0 within
-sbpcd.h.
-
-
-Setting up address and interface type:
---------------------------------------
-
-If your I/O port address is not 0x340, you have to look for the #defines near
-the beginning of sbpcd.h and configure them: set SBPRO to 0 or 1 or 2, and
-change CDROM_PORT to the address of your CDROM I/O port.
-
-Almost all of the "SoundBlaster compatible" cards behave like the no-sound
-interfaces, i.e. need SBPRO 0! 
-
-With "original" SB Pro cards, an initial setting of CD_volume through the
-sound card's MIXER register gets done.
-If you are using a "compatible" sound card of types "LaserMate" or "SPEA",
-you can set SOUND_BASE (in sbpcd.h) to get it done with your card, too...
-
-
-Using audio CDs:
-----------------
-
-Workman, WorkBone, xcdplayer, cdplayer and the nice little tool "cdplay" (see
-README.aztcd from the Aztech driver package) should work.
-
-The program CDplayer likes to talk to "/dev/mcd" only, xcdplayer wants
-"/dev/rsr0", workman loves "/dev/sr0" or "/dev/cdrom" - so, make the 
-appropriate links to use them without the need to supply parameters.
-
-
-Copying audio tracks:
----------------------
-
-The following program will copy track 1 (or a piece of it) from an audio CD
-into the file "track01":
-
-/*=================== begin program ========================================*/
-/*
- * read an audio track from a CD
- *
- * (c) 1994 Eberhard Moenkeberg <emoenke@gwdg.de>
- *          may be used & enhanced freely
- *
- * Due to non-existent sync bytes at the beginning of each audio frame (or due
- * to a firmware bug within all known drives?), it is currently a kind of
- * fortune if two consecutive frames fit together.
- * Usually, they overlap, or a little piece is missing. This happens in units
- * of 24-byte chunks. It has to get fixed by higher-level software (reading
- * until an overlap occurs, and then eliminate the overlapping chunks). 
- * ftp.gwdg.de:/pub/linux/misc/cdda2wav-sbpcd.*.tar.gz holds an example of
- * such an algorithm.
- * This example program further is missing to obtain the SubChannel data
- * which belong to each frame.
- *
- * This is only an example of the low-level access routine. The read data are
- * pure 16-bit CDDA values; they have to get converted to make sound out of
- * them.
- * It is no fun to listen to it without prior overlap/underlap correction!

-Known problems:
----------------
-
-Currently, the detection of disk change or removal is actively disabled.
-
-Most attempts to read the UPC/EAN code result in a stream of zeroes. All my

-
-This is the README for the sjcd cdrom driver, version 1.6.
-
-This file is meant as a tips & tricks edge for the usage of the SANYO CDR-H94A
-cdrom drive. It will grow as the questions arise. ;-)
-For info on configuring the ISP16 sound card look at Documentation/cdrom/isp16.
-
-The driver should work with any of the Panasonic, Sony or Mitsumi style
-CDROM interfaces.
-The cdrom interface on Media Magic's soft configurable sound card ISP16,
-which used to be included in the driver, is now supported in a separate module.
-This initialisation module will probably also work with other interfaces
-based on an OPTi 82C928 or 82C929 chip (like MAD16 and Mozart): see the
-documentation Documentation/cdrom/isp16.
-
-The device major for sjcd is 18, and minor is 0. Create a block special
-file in your /dev directory (e.g., /dev/sjcd) with these numbers.
-(For those who don't know, being root and doing the following should do
-the trick:
-  mknod -m 644 /dev/sjcd b 18 0
-and mount the cdrom by /dev/sjcd).
-
-The default configuration parameters are:
-  base address 0x340
-  no irq
-  no dma
-(Actually the CDR-H94A doesn't know how to use irq and dma.)
-As of version 1.2, setting base address at boot time is supported

-              README FOR LINUX SONY CDU-535/531 DRIVER
-              ========================================
-
-This is the Sony CDU-535 (and 531) driver version 0.7 for Linux.
-I do not think I have the documentation to add features like DMA support
-so if anyone else wants to pursue it or help me with it, please do.
-(I need to see what was done for the CDU-31A driver -- perhaps I can
-steal some of that code.)
-
-This is a Linux device driver for the Sony CDU-535 CDROM drive.  This is
-one of the older Sony drives with its own interface card (Sony bus).
-The DOS driver for this drive is named SONY_CDU.SYS - when you boot DOS
-your drive should be identified as a SONY CDU-535.  The driver works
-with a CDU-531 also.  One user reported that the driver worked on drives
-OEM'ed by Procomm, drive and interface board were labelled Procomm.
-
-The Linux driver is based on Corey Minyard's sonycd 0.3 driver for
-the CDU-31A.  Ron Jeppesen just changed the commands that were sent
-to the drive to correspond to the CDU-535 commands and registers.
-There were enough changes to let bugs creep in but it seems to be stable.
-Ron was able to tar an entire CDROM (should read all blocks) and built
-ghostview and xfig off Walnut Creek's X11R5/GNU CDROM.  xcdplayer and
-workman work with the driver.  Others have used the driver without
-problems except those dealing with wait loops (fixed in third release).
-Like Minyard's original driver this one uses a polled interface (this
-is also the default setup for the DOS driver).  It has not been tried
-with interrupts or DMA enabled on the board.
-
-REQUIREMENTS
-============
-
-	- Sony CDU-535 drive, preferably without interrupts and DMA 
-	  enabled on the card.
-
-	- Drive must be set up as unit 1.  Only the first unit will be 
-	  recognized
-
-	- You must enter your interface address into 
-          /usr/src/linux/drivers/cdrom/sonycd535.h and build the
-          appropriate kernel or use the "kernel command line" parameter
-                sonycd535=0x320
-          with the correct interface address.
-
-NOTES:
-======
-
-1) The drive MUST be turned on when booting or it will not be recognized!
-   (but see comments on modularized version below)
-
-2) when the cdrom device is opened the eject button is disabled to keep the
-   user from ejecting a mounted disk and replacing it with another.
-   Unfortunately xcdplayer and workman also open the cdrom device so you
-   have to use the eject button in the software.  Keep this in mind if your
-   cdrom player refuses to give up its disk -- exit workman or xcdplayer, or
-   umount the drive if it has been mounted.
-
-THANKS
-======
-
-Many thanks to Ron Jeppesen (ronj.an@site007.saic.com) for getting
-this project off the ground.  He wrote the initial release
-and the first two patches to this driver (0.1, 0.2, and 0.3).
-Thanks also to Eberhard Moenkeberg (emoenke@gwdg.de) for prodding
-me to place this code into the mainstream Linux source tree
-(as of Linux version 1.1.91), as well as some patches to make
-it a better device citizen.  Further thanks to Joel Katz
-<joelkatz@webchat.org> for his MODULE patches (see details below),
-Porfiri Claudio <C.Porfiri@nisms.tei.ericsson.se> for patches
-to make the driver work with the older CDU-510/515 series, and
-Heiko Eissfeldt <heiko@colossus.escape.de> for pointing out that
-the verify_area() checks were ignoring the results of said checks
-(note: verify_area() has since been replaced by access_ok()).
-
-(Acknowledgments from Ron Jeppesen in the 0.3 release:)
-Thanks to Corey Minyard who wrote the original CDU-31A driver on which
-this driver is based.  Thanks to Ken Pizzini and Bob Blair who provided 
-patches and feedback on the first release of this driver.

-------------------------------------------------------------------------------
-(The following is from Joel Katz <joelkatz@webchat.org>.)
-
-	To build a version of sony535.o that can be installed as a module,
-use the following command:
-
-gcc -c -D__KERNEL__ -DMODULE -O2 sonycd535.c -o sonycd535.o
-
-	To install the module, simply type:
-
-insmod sony535.o
-	or
-insmod sony535.o sonycd535=<address>
-
-	And to remove it:
-
-rmmod sony535
-
-	The code checks to see if MODULE is defined and behaves as it used
-to if MODULE is not defined. That means your patched file should behave
-exactly as it used to if compiled into the kernel.
-
-	I have an external drive, and I usually leave it powered off. I used
-to have to reboot if I needed to use the CDROM drive. Now I don't.
-
-	Even if you have an internal drive, why waste the 96K of memory
-(unswappable) that the driver uses if you use your CD-ROM drive infrequently?
-
-	This driver will not install (whether compiled in or loaded as a
-module) if the CDROM drive is not available during its initialization. This
-means that you can have the driver compiled into the kernel and still load
-the module later (assuming the driver doesn't install itself during
-power-on). This only wastes 12K when you boot with the CDROM drive off.
-
-	This is what I usually do; I leave the driver compiled into the
-kernel, but load it as a module if I powered the system up with the drive
-off and then later decided to use the CDROM drive.
-
-	Since the driver only uses a single page to point to the chunks,
-attempting to set the buffer cache to more than 2 Megabytes would be very
-bad; don't do that.

+configfs provides two additional API calls: configfs_depend_item() and

+--------------------------

+This parameter is only useful when kernelcore= is specified at boot time to

+are not movable so are not normally allocated from ZONE_MOVABLE. A non-zero
+value written to hugepages_treat_as_movable allows huge pages to be allocated

+can grow to the size of ZONE_MOVABLE by repeatedly entering the desired value

+How to use packet injection with mac80211
+=========================================
+
+mac80211 now allows arbitrary packets to be injected down any Monitor Mode
+interface from userland.  The packet you inject needs to be composed in the
+following format:
+
+ [ radiotap header  ]
+ [ ieee80211 header ]
+ [ payload ]
+
+The radiotap format is discussed in
+./Documentation/networking/radiotap-headers.txt.
+
+Despite 13 radiotap argument types are currently defined, most only make sense
+to appear on received packets.  Currently three kinds of argument are used by
+the injection code, although it knows to skip any other arguments that are
+present (facilitating replay of captured radiotap headers directly):
+
+ - IEEE80211_RADIOTAP_RATE - u8 arg in 500kbps units (0x02 --> 1Mbps)
+
+ - IEEE80211_RADIOTAP_ANTENNA - u8 arg, 0x00 = ant1, 0x01 = ant2
+
+ - IEEE80211_RADIOTAP_DBM_TX_POWER - u8 arg, dBm
+
+Here is an example valid radiotap header defining these three parameters
+
+	0x00, 0x00, // <-- radiotap version
+	0x0b, 0x00, // <- radiotap header length
+	0x04, 0x0c, 0x00, 0x00, // <-- bitmap
+	0x6c, // <-- rate
+	0x0c, //<-- tx power
+	0x01 //<-- antenna
+
+The ieee80211 header follows immediately afterwards, looking for example like
+this:
+
+	0x08, 0x01, 0x00, 0x00,
+	0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF,
+	0x13, 0x22, 0x33, 0x44, 0x55, 0x66,
+	0x13, 0x22, 0x33, 0x44, 0x55, 0x66,
+	0x10, 0x86
+
+Then lastly there is the payload.
+
+After composing the packet contents, it is sent by send()-ing it to a logical
+mac80211 interface that is in Monitor mode.  Libpcap can also be used,
+(which is easier than doing the work to bind the socket to the right
+interface), along the following lines:
+
+	ppcap = pcap_open_live(szInterfaceName, 800, 1, 20, szErrbuf);
+...
+	r = pcap_inject(ppcap, u8aSendBuffer, nLength);

+How to use radiotap headers
+===========================
+
+Pointer to the radiotap include file
+------------------------------------
+
+Radiotap headers are variable-length and extensible, you can get most of the
+information you need to know on them from:
+
+./include/net/ieee80211_radiotap.h
+
+This document gives an overview and warns on some corner cases.
+
+
+Structure of the header
+-----------------------
+
+There is a fixed portion at the start which contains a u32 bitmap that defines
+if the possible argument associated with that bit is present or not.  So if b0
+of the it_present member of ieee80211_radiotap_header is set, it means that
+the header for argument index 0 (IEEE80211_RADIOTAP_TSFT) is present in the
+argument area.
+
+   < 8-byte ieee80211_radiotap_header >
+   [ <possible argument bitmap extensions ... > ]
+   [ <argument> ... ]
+
+At the moment there are only 13 possible argument indexes defined, but in case
+we run out of space in the u32 it_present member, it is defined that b31 set
+indicates that there is another u32 bitmap following (shown as "possible
+argument bitmap extensions..." above), and the start of the arguments is moved
+forward 4 bytes each time.
+
+Note also that the it_len member __le16 is set to the total number of bytes
+covered by the ieee80211_radiotap_header and any arguments following.
+
+
+Requirements for arguments
+--------------------------
+
+After the fixed part of the header, the arguments follow for each argument
+index whose matching bit is set in the it_present member of
+ieee80211_radiotap_header.
+
+ - the arguments are all stored little-endian!
+
+ - the argument payload for a given argument index has a fixed size.  So
+   IEEE80211_RADIOTAP_TSFT being present always indicates an 8-byte argument is
+   present.  See the comments in ./include/net/ieee80211_radiotap.h for a nice
+   breakdown of all the argument sizes
+
+ - the arguments must be aligned to a boundary of the argument size using
+   padding.  So a u16 argument must start on the next u16 boundary if it isn't
+   already on one, a u32 must start on the next u32 boundary and so on.
+
+ - "alignment" is relative to the start of the ieee80211_radiotap_header, ie,
+   the first byte of the radiotap header.  The absolute alignment of that first
+   byte isn't defined.  So even if the whole radiotap header is starting at, eg,
+   address 0x00000003, still the first byte of the radiotap header is treated as
+   0 for alignment purposes.
+
+ - the above point that there may be no absolute alignment for multibyte
+   entities in the fixed radiotap header or the argument region means that you
+   have to take special evasive action when trying to access these multibyte
+   entities.  Some arches like Blackfin cannot deal with an attempt to
+   dereference, eg, a u16 pointer that is pointing to an odd address.  Instead
+   you have to use a kernel API get_unaligned() to dereference the pointer,
+   which will do it bytewise on the arches that require that.
+
+ - The arguments for a given argument index can be a compound of multiple types
+   together.  For example IEEE80211_RADIOTAP_CHANNEL has an argument payload
+   consisting of two u16s of total length 4.  When this happens, the padding
+   rule is applied dealing with a u16, NOT dealing with a 4-byte single entity.
+
+
+Example valid radiotap header
+-----------------------------
+
+	0x00, 0x00, // <-- radiotap version + pad byte
+	0x0b, 0x00, // <- radiotap header length
+	0x04, 0x0c, 0x00, 0x00, // <-- bitmap
+	0x6c, // <-- rate (in 500kHz units)
+	0x0c, //<-- tx power
+	0x01 //<-- antenna
+
+
+Using the Radiotap Parser
+-------------------------
+
+If you are having to parse a radiotap struct, you can radically simplify the
+job by using the radiotap parser that lives in net/wireless/radiotap.c and has
+its prototypes available in include/net/cfg80211.h.  You use it like this:
+
+#include <net/cfg80211.h>
+
+/* buf points to the start of the radiotap header part */
+
+int MyFunction(u8 * buf, int buflen)
+{
+	int pkt_rate_100kHz = 0, antenna = 0, pwr = 0;
+	struct ieee80211_radiotap_iterator iterator;
+	int ret = ieee80211_radiotap_iterator_init(&iterator, buf, buflen);
+
+	while (!ret) {
+
+		ret = ieee80211_radiotap_iterator_next(&iterator);
+
+		if (ret)
+			continue;
+
+		/* see if this argument is something we can use */
+
+		switch (iterator.this_arg_index) {
+		/*
+		 * You must take care when dereferencing iterator.this_arg
+		 * for multibyte types... the pointer is not aligned.  Use
+		 * get_unaligned((type *)iterator.this_arg) to dereference
+		 * iterator.this_arg for type "type" safely on all arches.
+		 */
+		case IEEE80211_RADIOTAP_RATE:
+			/* radiotap "rate" u8 is in
+			 * 500kbps units, eg, 0x02=1Mbps
+			 */
+			pkt_rate_100kHz = (*iterator.this_arg) * 5;
+			break;
+
+		case IEEE80211_RADIOTAP_ANTENNA:
+			/* radiotap uses 0 for 1st ant */
+			antenna = *iterator.this_arg);
+			break;
+
+		case IEEE80211_RADIOTAP_DBM_TX_POWER:
+			pwr = *iterator.this_arg;
+			break;
+
+		default:
+			break;
+		}
+	}  /* while more rt headers */
+
+	if (ret != -ENOENT)
+		return TXRX_DROP;
+
+	/* discard the radiotap header part */
+	buf += iterator.max_length;
+	buflen -= iterator.max_length;
+
+	...

+Freezing of tasks
+	(C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+I. What is the freezing of tasks?
+
+The freezing of tasks is a mechanism by which user space processes and some
+kernel threads are controlled during hibernation or system-wide suspend (on some
+architectures).
+
+II. How does it work?
+
+There are four per-task flags used for that, PF_NOFREEZE, PF_FROZEN, TIF_FREEZE
+and PF_FREEZER_SKIP (the last one is auxiliary).  The tasks that have
+PF_NOFREEZE unset (all user space processes and some kernel threads) are
+regarded as 'freezable' and treated in a special way before the system enters a
+suspend state as well as before a hibernation image is created (in what follows
+we only consider hibernation, but the description also applies to suspend).
+
+Namely, as the first step of the hibernation procedure the function
+freeze_processes() (defined in kernel/power/process.c) is called.  It executes
+try_to_freeze_tasks() that sets TIF_FREEZE for all of the freezable tasks and
+sends a fake signal to each of them.  A task that receives such a signal and has
+TIF_FREEZE set, should react to it by calling the refrigerator() function
+(defined in kernel/power/process.c), which sets the task's PF_FROZEN flag,
+changes its state to TASK_UNINTERRUPTIBLE and makes it loop until PF_FROZEN is
+cleared for it.  Then, we say that the task is 'frozen' and therefore the set of
+functions handling this mechanism is called 'the freezer' (these functions are
+defined in kernel/power/process.c and include/linux/freezer.h).  User space
+processes are generally frozen before kernel threads.
+
+It is not recommended to call refrigerator() directly.  Instead, it is
+recommended to use the try_to_freeze() function (defined in
+include/linux/freezer.h), that checks the task's TIF_FREEZE flag and makes the
+task enter refrigerator() if the flag is set.
+
+For user space processes try_to_freeze() is called automatically from the
+signal-handling code, but the freezable kernel threads need to call it
+explicitly in suitable places.  The code to do this may look like the following:
+
+	do {
+		hub_events();
+		wait_event_interruptible(khubd_wait,
+					!list_empty(&hub_event_list));
+		try_to_freeze();
+	} while (!signal_pending(current));
+
+(from drivers/usb/core/hub.c::hub_thread()).
+
+If a freezable kernel thread fails to call try_to_freeze() after the freezer has
+set TIF_FREEZE for it, the freezing of tasks will fail and the entire
+hibernation operation will be cancelled.  For this reason, freezable kernel
+threads must call try_to_freeze() somewhere.
+
+After the system memory state has been restored from a hibernation image and
+devices have been reinitialized, the function thaw_processes() is called in
+order to clear the PF_FROZEN flag for each frozen task.  Then, the tasks that
+have been frozen leave refrigerator() and continue running.
+
+III. Which kernel threads are freezable?
+
+Kernel threads are not freezable by default.  However, a kernel thread may clear
+PF_NOFREEZE for itself by calling set_freezable() (the resetting of PF_NOFREEZE
+directly is strongly discouraged).  From this point it is regarded as freezable
+and must call try_to_freeze() in a suitable place.
+
+IV. Why do we do that?
+
+Generally speaking, there is a couple of reasons to use the freezing of tasks:
+
+1. The principal reason is to prevent filesystems from being damaged after
+hibernation.  At the moment we have no simple means of checkpointing
+filesystems, so if there are any modifications made to filesystem data and/or
+metadata on disks, we cannot bring them back to the state from before the
+modifications.  At the same time each hibernation image contains some
+filesystem-related information that must be consistent with the state of the
+on-disk data and metadata after the system memory state has been restored from
+the image (otherwise the filesystems will be damaged in a nasty way, usually
+making them almost impossible to repair).  We therefore freeze tasks that might
+cause the on-disk filesystems' data and metadata to be modified after the
+hibernation image has been created and before the system is finally powered off.
+The majority of these are user space processes, but if any of the kernel threads
+may cause something like this to happen, they have to be freezable.
+
+2. The second reason is to prevent user space processes and some kernel threads
+from interfering with the suspending and resuming of devices.  A user space
+process running on a second CPU while we are suspending devices may, for
+example, be troublesome and without the freezing of tasks we would need some
+safeguards against race conditions that might occur in such a case.
+
+Although Linus Torvalds doesn't like the freezing of tasks, he said this in one
+of the discussions on LKML (http://lkml.org/lkml/2007/4/27/608):
+
+"RJW:> Why we freeze tasks at all or why we freeze kernel threads?
+
+Linus: In many ways, 'at all'.
+
+I _do_ realize the IO request queue issues, and that we cannot actually do
+s2ram with some devices in the middle of a DMA.  So we want to be able to
+avoid *that*, there's no question about that.  And I suspect that stopping
+user threads and then waiting for a sync is practically one of the easier
+ways to do so.
+
+So in practice, the 'at all' may become a 'why freeze kernel threads?' and
+freezing user threads I don't find really objectionable."
+
+Still, there are kernel threads that may want to be freezable.  For example, if
+a kernel that belongs to a device driver accesses the device directly, it in
+principle needs to know when the device is suspended, so that it doesn't try to
+access it at that time.  However, if the kernel thread is freezable, it will be
+frozen before the driver's .suspend() callback is executed and it will be
+thawed after the driver's .resume() callback has run, so it won't be accessing
+the device while it's suspended.
+
+3. Another reason for freezing tasks is to prevent user space processes from
+realizing that hibernation (or suspend) operation takes place.  Ideally, user
+space processes should not notice that such a system-wide operation has occurred
+and should continue running without any problems after the restore (or resume
+from suspend).  Unfortunately, in the most general case this is quite difficult
+to achieve without the freezing of tasks.  Consider, for example, a process
+that depends on all CPUs being online while it's running.  Since we need to
+disable nonboot CPUs during the hibernation, if this process is not frozen, it
+may notice that the number of CPUs has changed and may start to work incorrectly
+because of that.
+
+V. Are there any problems related to the freezing of tasks?
+
+Yes, there are.
+
+First of all, the freezing of kernel threads may be tricky if they depend one
+on another.  For example, if kernel thread A waits for a completion (in the
+TASK_UNINTERRUPTIBLE state) that needs to be done by freezable kernel thread B
+and B is frozen in the meantime, then A will be blocked until B is thawed, which
+may be undesirable.  That's why kernel threads are not freezable by default.
+
+Second, there are the following two problems related to the freezing of user
+space processes:
+1. Putting processes into an uninterruptible sleep distorts the load average.
+2. Now that we have FUSE, plus the framework for doing device drivers in
+userspace, it gets even more complicated because some userspace processes are
+now doing the sorts of things that kernel threads do
+(https://lists.linux-foundation.org/pipermail/linux-pm/2007-May/012309.html).
+
+The problem 1. seems to be fixable, although it hasn't been fixed so far.  The
+other one is more serious, but it seems that we can work around it by using
+hibernation (and suspend) notifiers (in that case, though, we won't be able to
+avoid the realization by the user space processes that the hibernation is taking
+place).
+
+There are also problems that the freezing of tasks tends to expose, although
+they are not directly related to it.  For example, if request_firmware() is
+called from a device driver's .resume() routine, it will timeout and eventually
+fail, because the user land process that should respond to the request is frozen
+at this point.  So, seemingly, the failure is due to the freezing of tasks.
+Suppose, however, that the firmware file is located on a filesystem accessible
+only through another device that hasn't been resumed yet.  In that case,
+request_firmware() will fail regardless of whether or not the freezing of tasks
+is used.  Consequently, the problem is not really related to the freezing of
+tasks, since it generally exists anyway.  [The solution to this particular
+problem is to keep the firmware in memory after it's loaded for the first time
+and upload if from memory to the device whenever necessary.]

-A: All such kernel threads need to be fixed, one by one. Select the
-place where the thread is safe to be frozen (no kernel semaphores
-should be held at that point and it must be safe to sleep there), and
-add:
-
-       try_to_freeze();
-
-If the thread is needed for writing the image to storage, you should
-instead set the PF_NOFREEZE process flag when creating the thread (and
-be very careful).
+Q: What is the freezing of tasks and why are we using it?
 
+A: The freezing of tasks is a mechanism by which user space processes and some
+kernel threads are controlled during hibernation or system-wide suspend (on some
+architectures).  See freezing-of-tasks.txt for details.
 
 Q: What is the difference between "platform" and "shutdown"?

+FC Remote Ports (rports)
+========================================================================
+<< To Be Supplied >>
+
+
+FC Virtual Ports (vports)
+========================================================================
+
+Overview:
+-------------------------------
+
+  New FC standards have defined mechanisms which allows for a single physical
+  port to appear on as multiple communication ports. Using the N_Port Id
+  Virtualization (NPIV) mechanism, a point-to-point connection to a Fabric
+  can be assigned more than 1 N_Port_ID.  Each N_Port_ID appears as a
+  separate port to other endpoints on the fabric, even though it shares one
+  physical link to the switch for communication. Each N_Port_ID can have a
+  unique view of the fabric based on fabric zoning and array lun-masking
+  (just like a normal non-NPIV adapter).  Using the Virtual Fabric (VF)
+  mechanism, adding a fabric header to each frame allows the port to
+  interact with the Fabric Port to join multiple fabrics. The port will
+  obtain an N_Port_ID on each fabric it joins. Each fabric will have its
+  own unique view of endpoints and configuration parameters.  NPIV may be
+  used together with VF so that the port can obtain multiple N_Port_IDs
+  on each virtual fabric.
+
+  The FC transport is now recognizing a new object - a vport.  A vport is
+  an entity that has a world-wide unique World Wide Port Name (wwpn) and
+  World Wide Node Name (wwnn). The transport also allows for the FC4's to
+  be specified for the vport, with FCP_Initiator being the primary role
+  expected. Once instantiated by one of the above methods, it will have a
+  distinct N_Port_ID and view of fabric endpoints and storage entities.
+  The fc_host associated with the physical adapter will export the ability
+  to create vports. The transport will create the vport object within the
+  Linux device tree, and instruct the fc_host's driver to instantiate the
+  virtual port. Typically, the driver will create a new scsi_host instance
+  on the vport, resulting in a unique <H,C,T,L> namespace for the vport.
+  Thus, whether a FC port is based on a physical port or on a virtual port,
+  each will appear as a unique scsi_host with its own target and lun space.
+
+  Note: At this time, the transport is written to create only NPIV-based
+    vports. However, consideration was given to VF-based vports and it
+    should be a minor change to add support if needed.  The remaining
+    discussion will concentrate on NPIV.
+
+  Note: World Wide Name assignment (and uniqueness guarantees) are left
+    up to an administrative entity controling the vport. For example,
+    if vports are to be associated with virtual machines, a XEN mgmt
+    utility would be responsible for creating wwpn/wwnn's for the vport,
+    using it's own naming authority and OUI. (Note: it already does this
+    for virtual MAC addresses).
+
+
+Device Trees and Vport Objects:
+-------------------------------
+
+  Today, the device tree typically contains the scsi_host object,
+  with rports and scsi target objects underneath it. Currently the FC
+  transport creates the vport object and places it under the scsi_host
+  object corresponding to the physical adapter.  The LLDD will allocate
+  a new scsi_host for the vport and link it's object under the vport.
+  The remainder of the tree under the vports scsi_host is the same
+  as the non-NPIV case. The transport is written currently to easily
+  allow the parent of the vport to be something other than the scsi_host.
+  This could be used in the future to link the object onto a vm-specific
+  device tree. If the vport's parent is not the physical port's scsi_host,
+  a symbolic link to the vport object will be placed in the physical
+  port's scsi_host.
+
+  Here's what to expect in the device tree :
+   The typical Physical Port's Scsi_Host:
+     /sys/devices/.../host17/
+   and it has the typical decendent tree:
+     /sys/devices/.../host17/rport-17:0-0/target17:0:0/17:0:0:0:
+   and then the vport is created on the Physical Port:
+     /sys/devices/.../host17/vport-17:0-0
+   and the vport's Scsi_Host is then created:
+     /sys/devices/.../host17/vport-17:0-0/host18
+   and then the rest of the tree progresses, such as:
+     /sys/devices/.../host17/vport-17:0-0/host18/rport-18:0-0/target18:0:0/18:0:0:0:
+
+  Here's what to expect in the sysfs tree :
+   scsi_hosts:
+     /sys/class/scsi_host/host17                physical port's scsi_host
+     /sys/class/scsi_host/host18                vport's scsi_host
+   fc_hosts:
+     /sys/class/fc_host/host17                  physical port's fc_host
+     /sys/class/fc_host/host18                  vport's fc_host
+   fc_vports:
+     /sys/class/fc_vports/vport-17:0-0          the vport's fc_vport
+   fc_rports:
+     /sys/class/fc_remote_ports/rport-17:0-0    rport on the physical port
+     /sys/class/fc_remote_ports/rport-18:0-0    rport on the vport
+
+
+Vport Attributes:
+-------------------------------
+
+  The new fc_vport class object has the following attributes
+
+     node_name:                                                 Read_Only
+       The WWNN of the vport
+
+     port_name:                                                 Read_Only
+       The WWPN of the vport
+
+     roles:                                                     Read_Only
+       Indicates the FC4 roles enabled on the vport.
+
+     symbolic_name:                                             Read_Write
+       A string, appended to the driver's symbolic port name string, which
+       is registered with the switch to identify the vport. For example,
+       a hypervisor could set this string to "Xen Domain 2 VM 5 Vport 2",
+       and this set of identifiers can be seen on switch management screens
+       to identify the port.
+
+     vport_delete:                                              Write_Only
+       When written with a "1", will tear down the vport.
+
+     vport_disable:                                             Write_Only
+       When written with a "1", will transition the vport to a disabled.
+       state.  The vport will still be instantiated with the Linux kernel,
+       but it will not be active on the FC link.
+       When written with a "0", will enable the vport.
+
+     vport_last_state:                                          Read_Only
+       Indicates the previous state of the vport.  See the section below on
+       "Vport States".
+
+     vport_state:                                               Read_Only
+       Indicates the state of the vport.  See the section below on
+       "Vport States".
+
+     vport_type:                                                Read_Only
+       Reflects the FC mechanism used to create the virtual port.
+       Only NPIV is supported currently.
+
+
+  For the fc_host class object, the following attributes are added for vports:
+
+     max_npiv_vports:                                           Read_Only
+       Indicates the maximum number of NPIV-based vports that the
+       driver/adapter can support on the fc_host.
+
+     npiv_vports_inuse:                                         Read_Only
+       Indicates how many NPIV-based vports have been instantiated on the
+       fc_host.
+
+     vport_create:                                              Write_Only
+       A "simple" create interface to instantiate a vport on an fc_host.
+       A "<WWPN>:<WWNN>" string is written to the attribute. The transport
+       then instantiates the vport object and calls the LLDD to create the
+       vport with the role of FCP_Initiator.  Each WWN is specified as 16
+       hex characters and may *not* contain any prefixes (e.g. 0x, x, etc).
+
+     vport_delete:                                              Write_Only
+        A "simple" delete interface to teardown a vport. A "<WWPN>:<WWNN>"
+        string is written to the attribute. The transport will locate the
+        vport on the fc_host with the same WWNs and tear it down.  Each WWN
+        is specified as 16 hex characters and may *not* contain any prefixes
+        (e.g. 0x, x, etc).
+
+
+Vport States:
+-------------------------------
+
+  Vport instantiation consists of two parts:
+    - Creation with the kernel and LLDD. This means all transport and
+      driver data structures are built up, and device objects created.
+      This is equivalent to a driver "attach" on an adapter, which is
+      independent of the adapter's link state.
+    - Instantiation of the vport on the FC link via ELS traffic, etc.
+      This is equivalent to a "link up" and successfull link initialization.
+  Futher information can be found in the interfaces section below for
+  Vport Creation.
+
+  Once a vport has been instantiated with the kernel/LLDD, a vport state
+  can be reported via the sysfs attribute. The following states exist:
+
+    FC_VPORT_UNKNOWN            - Unknown
+      An temporary state, typically set only while the vport is being
+      instantiated with the kernel and LLDD.
+
+    FC_VPORT_ACTIVE             - Active
+      The vport has been successfully been created on the FC link.
+      It is fully functional.
+
+    FC_VPORT_DISABLED           - Disabled
+      The vport instantiated, but "disabled". The vport is not instantiated
+      on the FC link. This is equivalent to a physical port with the
+      link "down".
+
+    FC_VPORT_LINKDOWN           - Linkdown
+      The vport is not operational as the physical link is not operational.
+
+    FC_VPORT_INITIALIZING       - Initializing
+      The vport is in the process of instantiating on the FC link.
+      The LLDD will set this state just prior to starting the ELS traffic
+      to create the vport. This state will persist until the vport is
+      successfully created (state becomes FC_VPORT_ACTIVE) or it fails
+      (state is one of the values below).  As this state is transitory,
+      it will not be preserved in the "vport_last_state".
+
+    FC_VPORT_NO_FABRIC_SUPP     - No Fabric Support
+      The vport is not operational. One of the following conditions were
+      encountered:
+       - The FC topology is not Point-to-Point
+       - The FC port is not connected to an F_Port
+       - The F_Port has indicated that NPIV is not supported.
+
+    FC_VPORT_NO_FABRIC_RSCS     - No Fabric Resources
+      The vport is not operational. The Fabric failed FDISC with a status
+      indicating that it does not have sufficient resources to complete
+      the operation.
+
+    FC_VPORT_FABRIC_LOGOUT      - Fabric Logout
+      The vport is not operational. The Fabric has LOGO'd the N_Port_ID
+      associated with the vport.
+
+    FC_VPORT_FABRIC_REJ_WWN     - Fabric Rejected WWN
+      The vport is not operational. The Fabric failed FDISC with a status
+      indicating that the WWN's are not valid.
+
+    FC_VPORT_FAILED             - VPort Failed
+      The vport is not operational. This is a catchall for all other
+      error conditions.
+
+
+  The following state table indicates the different state transitions:

+
+
+Transport <-> LLDD Interfaces :
+-------------------------------
+
+Vport support by LLDD:
+
+  The LLDD indicates support for vports by supplying a vport_create()
+  function in the transport template.  The presense of this function will
+  cause the creation of the new attributes on the fc_host.  As part of
+  the physical port completing its initialization relative to the
+  transport, it should set the max_npiv_vports attribute to indicate the
+  maximum number of vports the driver and/or adapter supports.
+
+
+Vport Creation:
+
+  The LLDD vport_create() syntax is:
+
+      int vport_create(struct fc_vport *vport, bool disable)
+
+    where:
+      vport:    Is the newly allocated vport object
+      disable:  If "true", the vport is to be created in a disabled stated.
+                If "false", the vport is to be enabled upon creation.
+
+  When a request is made to create a new vport (via sgio/netlink, or the
+  vport_create fc_host attribute), the transport will validate that the LLDD
+  can support another vport (e.g. max_npiv_vports > npiv_vports_inuse).
+  If not, the create request will be failed.  If space remains, the transport
+  will increment the vport count, create the vport object, and then call the
+  LLDD's vport_create() function with the newly allocated vport object.
+
+  As mentioned above, vport creation is divided into two parts:
+    - Creation with the kernel and LLDD. This means all transport and
+      driver data structures are built up, and device objects created.
+      This is equivalent to a driver "attach" on an adapter, which is
+      independent of the adapter's link state.
+    - Instantiation of the vport on the FC link via ELS traffic, etc.
+      This is equivalent to a "link up" and successfull link initialization.
+
+  The LLDD's vport_create() function will not synchronously wait for both
+  parts to be fully completed before returning. It must validate that the
+  infrastructure exists to support NPIV, and complete the first part of
+  vport creation (data structure build up) before returning.  We do not
+  hinge vport_create() on the link-side operation mainly because:
+    - The link may be down. It is not a failure if it is. It simply
+      means the vport is in an inoperable state until the link comes up.
+      This is consistent with the link bouncing post vport creation.
+    - The vport may be created in a disabled state.
+    - This is consistent with a model where:  the vport equates to a
+      FC adapter. The vport_create is synonymous with driver attachment
+      to the adapter, which is independent of link state.
+
+    Note: special error codes have been defined to delineate infrastructure
+      failure cases for quicker resolution.
+
+  The expected behavior for the LLDD's vport_create() function is:
+    - Validate Infrastructure:
+        - If the driver or adapter cannot support another vport, whether
+            due to improper firmware, (a lie about) max_npiv, or a lack of
+            some other resource - return VPCERR_UNSUPPORTED.
+        - If the driver validates the WWN's against those already active on
+            the adapter and detects an overlap - return VPCERR_BAD_WWN.
+        - If the driver detects the topology is loop, non-fabric, or the
+            FLOGI did not support NPIV - return VPCERR_NO_FABRIC_SUPP.
+    - Allocate data structures. If errors are encountered, such as out
+        of memory conditions, return the respective negative Exxx error code.
+    - If the role is FCP Initiator, the LLDD is to :
+        - Call scsi_host_alloc() to allocate a scsi_host for the vport.
+        - Call scsi_add_host(new_shost, &vport->dev) to start the scsi_host
+          and bind it as a child of the vport device.
+        - Initializes the fc_host attribute values.
+    - Kick of further vport state transitions based on the disable flag and
+        link state - and return success (zero).
+
+  LLDD Implementers Notes:
+  - It is suggested that there be a different fc_function_templates for
+    the physical port and the virtual port.  The physical port's template
+    would have the vport_create, vport_delete, and vport_disable functions,
+    while the vports would not.
+  - It is suggested that there be different scsi_host_templates
+    for the physical port and virtual port. Likely, there are driver
+    attributes, embedded into the scsi_host_template, that are applicable
+    for the physical port only (link speed, topology setting, etc). This
+    ensures that the attributes are applicable to the respective scsi_host.
+
+
+Vport Disable/Enable:
+
+  The LLDD vport_disable() syntax is:
+
+      int vport_disable(struct fc_vport *vport, bool disable)
+
+    where:
+      vport:    Is vport to to be enabled or disabled
+      disable:  If "true", the vport is to be disabled.
+                If "false", the vport is to be enabled.
+
+  When a request is made to change the disabled state on a vport, the
+  transport will validate the request against the existing vport state.
+  If the request is to disable and the vport is already disabled, the
+  request will fail. Similarly, if the request is to enable, and the
+  vport is not in a disabled state, the request will fail.  If the request
+  is valid for the vport state, the transport will call the LLDD to
+  change the vport's state.
+
+  Within the LLDD, if a vport is disabled, it remains instantiated with
+  the kernel and LLDD, but it is not active or visible on the FC link in
+  any way. (see Vport Creation and the 2 part instantiation discussion).
+  The vport will remain in this state until it is deleted or re-enabled.
+  When enabling a vport, the LLDD reinstantiates the vport on the FC
+  link - essentially restarting the LLDD statemachine (see Vport States
+  above).
+
+
+Vport Deletion:
+
+  The LLDD vport_delete() syntax is:
+
+      int vport_delete(struct fc_vport *vport)
+
+    where:
+      vport:    Is vport to delete
+
+  When a request is made to delete a vport (via sgio/netlink, or via the
+  fc_host or fc_vport vport_delete attributes), the transport will call
+  the LLDD to terminate the vport on the FC link, and teardown all other
+  datastructures and references.  If the LLDD completes successfully,
+  the transport will teardown the vport objects and complete the vport
+  removal.  If the LLDD delete request fails, the vport object will remain,
+  but will be in an indeterminate state.
+
+  Within the LLDD, the normal code paths for a scsi_host teardown should
+  be followed. E.g. If the vport has a FCP Initiator role, the LLDD
+  will call fc_remove_host() for the vports scsi_host, followed by
+  scsi_remove_host() and scsi_host_put() for the vports scsi_host.
+
+
+Other:
+  fc_host port_type attribute:
+    There is a new fc_host port_type value - FC_PORTTYPE_NPIV. This value
+    must be set on all vport-based fc_hosts.  Normally, on a physical port,
+    the port_type attribute would be set to NPORT, NLPORT, etc based on the
+    topology type and existence of the fabric. As this is not applicable to
+    a vport, it makes more sense to report the FC mechanism used to create
+    the vport.
+
+  Driver unload:
+    FC drivers are required to call fc_remove_host() prior to calling
+    scsi_remove_host().  This allows the fc_host to tear down all remote
+    ports prior the scsi_host being torn down.  The fc_remove_host() call
+    was updated to remove all vports for the fc_host as well.

-Documentation for the AD1816(A) sound driver
-============================================
-
-Installation:
--------------
-
-To get your AD1816(A) based sound card work, you'll have to enable support for
-experimental code ("Prompt for development and/or incomplete code/drivers")
-and isapnp ("Plug and Play support", "ISA Plug and Play support"). Enable
-"Sound card support", "OSS modules support" and "Support for AD1816(A) based
-cards (EXPERIMENTAL)" in the sound configuration menu, too. Now build, install
-and reboot the new kernel as usual.
-
-Features:
----------
-
-List of features supported by this driver:
-- full-duplex support
-- supported audio formats: unsigned 8bit, signed 16bit little endian, 
-                           signed 16bit big endian, µ-law, A-law
-- supported channels: mono and stereo
-- supported recording sources: Master, CD, Line, Line1, Line2, Mic
-- supports phat 3d stereo circuit (Line 3)
-
-
-Supported cards:
-----------------
-
-The following cards are known to work with this driver:
-- Terratec Base 1 
-- Terratec Base 64 
-- HP Kayak 
-- Acer FX-3D
-- SY-1816 
-- Highscreen Sound-Boostar 32 Wave 3D
-- Highscreen Sound-Boostar 16 
-- AVM Apex Pro card 
-- (Aztech SC-16 3D) 
-- (Newcom SC-16 3D) 
-- (Terratec EWS64S) 
-
-Cards listed in brackets are not supported reliable. If you have such a card 
-you should add the extra parameter:
-  options=1
-when loading the ad1816 module via modprobe. 
-
-
-Troubleshooting:
-----------------
-
-First of all you should check, if the driver has been loaded
-properly.
-
-If loading of the driver succeeds, but playback/capture fails, check
-if you used the correct values for irq, dma and dma2 when loading the module.
-If one of them is wrong you usually get the following error message:
-
-Nov  6 17:06:13 tek01 kernel: Sound: DMA (output) timed out - IRQ/DRQ config error?
-
-If playback/capture is too fast or to slow, you should have a look at
-the clock chip of your sound card. The AD1816 was designed for a 33MHz
-oscillator, however most sound card manufacturer use slightly
-different oscillators as they are cheaper than 33MHz oscillators. If
-you have such a card you have to adjust the ad1816_clockfreq parameter
-above. For example: For a card using a 32.875MHz oscillator use
-ad1816_clockfreq=32875 instead of ad1816_clockfreq=33000.
-
-
-Updates, bugfixes and bugreports:
---------------------------------
-
-As the driver is still experimental and under development, you should
-watch out for updates.  Updates of the driver are available on the
-Internet from one of my home pages:
-  http://www.student.informatik.tu-darmstadt.de/~tek/projects/linux.html
-or:
-  http://www.tu-darmstadt.de/~tek01/projects/linux.html
-
-Bugreports, bugfixes and related questions should be sent via E-Mail to:
-  tek@rbg.informatik.tu-darmstadt.de

-Documentation for the NeoMagic 256AV/256ZX sound driver
-=======================================================
-
-You're looking at version 1.1 of the driver.  (Woohoo!) It has been
-successfully tested against the following laptop models:
-
-	Sony Z505S/Z505SX/Z505DX/Z505RX
-	Sony F150, F160, F180, F250, F270, F280, PCG-F26
-	Dell Latitude CPi, CPt (various submodels)
-
-There are a few caveats, which is why you should read the entirety of
-this document first.
-
-This driver was developed without any support or assistance from
-NeoMagic.  There is no warranty, expressed, implied, or otherwise.  It
-is free software in the public domain; feel free to use it, sell it,
-give it to your best friends, even claim that you wrote it (but why?!)
-but don't go whining to me, NeoMagic, Sony, Dell, or anyone else
-when it blows up your computer.
-
-Version 1.1 contains a change to try and detect non-AC97 versions of
-the hardware, and not install itself appropriately.  It should also
-reinitialize the hardware on an APM resume event, assuming that APM
-was configured into your kernel.
-
-============
-Installation
-============
-
-Enable the sound drivers, the OSS sound drivers, and then the NM256
-driver.  The NM256 driver *must* be configured as a module (it won't
-give you any other choice).
-
-Next, do the usual "make modules" and "make modules_install".
-Finally, insmod the soundcore, sound and nm256 modules.
-
-When the nm256 driver module is loaded, you should see a couple of
-confirmation messages in the kernel logfile indicating that it found
-the device (the device does *not* use any I/O ports or DMA channels).
-Now try playing a wav file, futz with the CD-ROM if you have one, etc.
-
-The NM256 is entirely a PCI-based device, and all the necessary
-information is automatically obtained from the card.  It can only be
-configured as a module in a vain attempt to prevent people from
-hurting themselves.  It works correctly if it shares an IRQ with
-another device (it normally shares IRQ 9 with the builtin eepro100
-ethernet on the Sony Z505 laptops). 
-
-It does not run the card in any sort of compatibility mode. It will
-not work on laptops that have the SB16-compatible, AD1848-compatible
-or CS4232-compatible codec/mixer; you will want to use the appropriate
-compatible OSS driver with these chipsets.  I cannot provide any
-assistance with machines using the SB16, AD1848 or CS4232 compatible
-versions.  (The driver now attempts to detect the mixer version, and
-will refuse to load if it believes the hardware is not
-AC97-compatible.)
-
-The sound support is very basic, but it does include simultaneous
-playback and record capability.  The mixer support is also quite
-simple, although this is in keeping with the rather limited
-functionality of the chipset.
-
-There is no hardware synthesizer available, as the Losedows OPL-3 and
-MIDI support is done via hardware emulation.
-
-Only three recording devices are available on the Sony: the
-microphone, the CD-ROM input, and the volume device (which corresponds
-to the stereo output).  (Other devices may be available on other
-models of laptops.)  The Z505 series does not have a builtin CD-ROM,
-so of course the CD-ROM input doesn't work.  It does work on laptops
-with a builtin CD-ROM drive.
-
-The mixer device does not appear to have any tone controls, at least
-on the Z505 series.  The mixer module checks for tone controls in the
-AC97 mixer, and will enable them if they are available.
-
-==============
-Known problems
-==============
-
-  * There are known problems with PCMCIA cards and the eepro100 ethernet 
-    driver on the Z505S/Z505SX/Z505DX.  Keep reading.
-
-  * There are also potential problems with using a virtual X display, and
-    also problems loading the module after the X server has been started. 
-    Keep reading.
-
-  * The volume control isn't anywhere near linear.  Sorry.  This will be
-    fixed eventually, when I get sufficiently annoyed with it.  (I doubt
-    it will ever be fixed now, since I've never gotten sufficiently
-    annoyed with it and nobody else seems to care.)
-
-  * There are reports that the CD-ROM volume is very low.  Since I do not
-    have a CD-ROM equipped laptop, I cannot test this (it's kinda hard to
-    do remotely).
-
-  * Only 8 fixed-rate speeds are supported.  This is mainly a chipset
-    limitation.  It may be possible to support other speeds in the future.
-
-  * There is no support for the telephone mixer/codec.  There is support
-    for a phonein/phoneout device in the mixer driver;  whether or not 
-    it does anything is anyone's guess.  (Reports on this would be
-    appreciated.  You'll have to figure out how to get the phone to
-    go off-hook before it'll work, tho.)
-
-  * This driver was not written with any cooperation or support from
-    NeoMagic.  If you have any questions about this, see their website
-    for their official stance on supporting open source drivers.
-
-============
-Video memory
-============
-
-The NeoMagic sound engine uses a portion of the display memory to hold
-the sound buffer.  (Crazy, eh?)  The NeoMagic video BIOS sets up a
-special pointer at the top of video RAM to indicate where the top of
-the audio buffer should be placed.
-
-At the present time XFree86 is apparently not aware of this.  It will
-thus write over either the pointer or the sound buffer with abandon.
-(Accelerated-X seems to do a better job here.)
-
-This implies a few things:
-
-  * Sometimes the NM256 driver has to guess at where the buffer 
-    should be placed, especially if the module is loaded after the
-    X server is started.  It's usually correct, but it will consistently
-    fail on the Sony F250.
-
-  * Virtual screens greater than 1024x768x16 under XFree86 are
-    problematic on laptops with only 2.5MB of screen RAM. This
-    includes all of the 256AV-equipped laptops.  (Virtual displays
-    may or may not work on the 256ZX, which has at least 4MB of
-    video RAM.)
-
-If you start having problems with random noise being output either
-constantly (this is the usual symptom on the F250), or when windows
-are moved around (this is the usual symptom when using a virtual
-screen), the best fix is to
-
-  * Don't use a virtual frame buffer.
-  * Make sure you load the NM256 module before the X server is
-    started.
-
-On the F250, it is possible to force the driver to load properly even
-after the XFree86 server is started by doing:
-
-	insmod nm256 buffertop=0x25a800
-
-This forces the audio buffers to the correct offset in screen RAM.
-
-One user has reported a similar problem on the Sony F270, although
-others apparently aren't seeing any problems.  His suggested command
-is
-
-	insmod nm256 buffertop=0x272800
-
-=================
-Official WWW site
-=================
-
-The official site for the NM256 driver is:
-
-	http://www.uglx.org/sony.html
-
-You should always be able to get the latest version of the driver there,
-and the driver will be supported for the foreseeable future.
-
-==============
-Z505RX and IDE
-==============
-
-There appears to be a problem with the IDE chipset on the Z505RX; one
-of the symptoms is that sound playback periodically hangs (when the
-disk is accessed).  The user reporting the problem also reported that
-enabling all of the IDE chipset workarounds in the kernel solved the
-problem, tho obviously only one of them should be needed--if someone
-can give me more details I would appreciate it.
-
-==============================
-Z505S/Z505SX on-board Ethernet
-==============================
-
-If you're using the on-board Ethernet Pro/100 ethernet support on the Z505
-series, I strongly encourage you to download the latest eepro100 driver from
-Donald Becker's site:
-
-	ftp://cesdis.gsfc.nasa.gov/pub/linux/drivers/test/eepro100.c
-
-There was a reported problem on the Z505SX that if the ethernet
-interface is disabled and reenabled while the sound driver is loaded,
-the machine would lock up.  I have included a workaround that is
-working satisfactorily.  However, you may occasionally see a message
-about "Releasing interrupts, over 1000 bad interrupts" which indicates
-that the workaround is doing its job.
-
-==================================
-PCMCIA and the Z505S/Z505SX/Z505DX
-==================================
-
-There is also a known problem with the Sony Z505S and Z505SX hanging
-if a PCMCIA card is inserted while the ethernet driver is loaded, or
-in some cases if the laptop is suspended.  This is caused by tons of
-spurious IRQ 9s, probably generated from the PCMCIA or ACPI bridges.
-
-There is currently no fix for the problem that works in every case.
-The only known workarounds are to disable the ethernet interface
-before inserting or removing a PCMCIA card, or with some cards
-disabling the PCMCIA card before ejecting it will also help the
-problem with the laptop hanging when the card is ejected.
-
-One user has reported that setting the tcic's cs_irq to some value
-other than 9 (like 11) fixed the problem.  This doesn't work on my
-Z505S, however--changing the value causes the cardmgr to stop seeing
-card insertions and removals, cards don't seem to work correctly, and
-I still get hangs if a card is inserted when the kernel is booted.
-
-Using the latest ethernet driver and pcmcia package allows me to
-insert an Adaptec 1480A SlimScsi card without the laptop hanging,
-although I still have to shut down the card before ejecting or
-powering down the laptop.  However, similar experiments with a DE-660
-ethernet card still result in hangs when the card is inserted.  I am
-beginning to think that the interrupts are CardBus-related, since the
-Adaptec card is a CardBus card, and the DE-660 is not; however, I
-don't have any other CardBus cards to test with.
-
-======
-Thanks
-======
-
-First, I want to thank everyone (except NeoMagic of course) for their
-generous support and encouragement.  I'd like to list everyone's name
-here that replied during the development phase, but the list is
-amazingly long.
-
-I will be rather unfair and single out a few people, however:
-
-	Justin Maurer, for being the first random net.person to try it,
-	and for letting me login to his Z505SX to get it working there
-
-	Edi Weitz for trying out several different versions, and giving
-	me a lot of useful feedback
-
-	Greg Rumple for letting me login remotely to get the driver 
-	functional on the 256ZX, for his assistance on tracking
-	down all sorts of random stuff, and for trying out Accel-X
-
-	Zach Brown, for the initial AC97 mixer interface design
-
-	Jeff Garzik, for various helpful suggestions on the AC97
-	interface
-
-	"Mr. Bumpy" for feedback on the Z505RX
-
-	Bill Nottingham, for generous assistance in getting the mixer ID
-	code working
-
-=================
-Previous versions
-=================
-
-Versions prior to 0.3 (aka `noname') had problems with weird artifacts
-in the output and failed to set the recording rate properly.  These
-problems have long since been fixed.
-
-Versions prior to 0.5 had problems with clicks in the output when
-anything other than 16-bit stereo sound was being played, and also had
-periodic clicks when recording.
-
-Version 0.7 first incorporated support for the NM256ZX chipset, which
-is found on some Dell Latitude laptops (the CPt, and apparently
-some CPi models as well).  It also included the generic AC97
-mixer module.
-
-Version 0.75 renamed all the functions and files with slightly more
-generic names.
-
-Note that previous versions of this document claimed that recording was
-8-bit only; it actually has been working for 16-bits all along.

-Documentation for the OPL3-SA2, SA3, and SAx driver (opl3sa2.o)
----------------------------------------------------------------
-
-Scott Murray, scott@spiteful.org
-January 7, 2001
-
-NOTE: All trade-marked terms mentioned below are properties of their
-      respective owners.
-
-
-Supported Devices
------------------
-
-This driver is for PnP soundcards based on the following Yamaha audio
-controller chipsets:
-
-YMF711 aka OPL3-SA2
-YMF715 and YMF719 aka OPL3-SA3
-
-Up until recently (December 2000), I'd thought the 719 to be a
-different chipset, the OPL3-SAx.  After an email exhange with
-Yamaha, however, it turns out that the 719 is just a re-badged
-715, and the chipsets are identical.  The chipset detection code
-has been updated to reflect this.
-
-Anyways, all of these chipsets implement the following devices:
-
-OPL3 FM synthesizer
-Soundblaster Pro
-Microsoft/Windows Sound System
-MPU401 MIDI interface
-
-Note that this driver uses the MSS device, and to my knowledge these
-chipsets enforce an either/or situation with the Soundblaster Pro
-device and the MSS device.  Since the MSS device has better
-capabilities, I have implemented the driver to use it.
-
-
-Mixer Channels
---------------
-
-Older versions of this driver (pre-December 2000) had two mixers,
-an OPL3-SA2 or SA3 mixer and a MSS mixer.  The OPL3-SA[23] mixer
-device contained a superset of mixer channels consisting of its own
-channels and all of the MSS mixer channels.  To simplify the driver
-considerably, and to partition functionality better, the OPL3-SA[23]
-mixer device now contains has its own specific mixer channels.  They
-are:
-
-Volume     - Hardware master volume control
-Bass       - SA3 only, now supports left and right channels
-Treble     - SA3 only, now supports left and right channels
-Microphone - Hardware microphone input volume control
-Digital1   - Yamaha 3D enhancement "Wide" mixer
-
-All other mixer channels (e.g. "PCM", "CD", etc.) now have to be
-controlled via the "MS Sound System (CS4231)" mixer.  To facilitate
-this, the mixer device creation order has been switched so that
-the MSS mixer is created first.  This allows accessing the majority
-of the useful mixer channels even via single mixer-aware tools
-such as "aumix".
-
-
-Plug 'n Play
-------------
-
-In previous kernels (2.2.x), some configuration was required to
-get the driver to talk to the card.  Being the new millennium and
-all, the 2.4.x kernels now support auto-configuration if ISA PnP
-support is configured in.  Theoretically, the driver even supports
-having more than one card in this case.
-
-With the addition of PnP support to the driver, two new parameters
-have been added to control it:
-
-isapnp   - set to 0 to disable ISA PnP card detection
-
-multiple - set to 0 to disable multiple PnP card detection
-
-
-Optional Parameters
--------------------
-
-Recent (December 2000) additions to the driver (based on a patch
-provided by Peter Englmaier) are two new parameters:
-
-ymode -    Set Yamaha 3D enhancement mode:
-           0 = Desktop/Normal  5-12 cm speakers
-           1 = Notebook PC (1) 3 cm speakers
-           2 = Notebook PC (2) 1.5 cm speakers
-           3 = Hi-Fi           16-38 cm speakers
-
-loopback - Set A/D input source. Useful for echo cancellation:
-           0 = Mic Right channel (default)
-           1 = Mono output loopback
-
-The ymode parameter has been tested and does work.  The loopback
-parameter, however, is untested.  Any feedback on its usefulness
-would be appreciated.

-
-Manual Configuration
---------------------
-
-If for some reason you decide not to compile ISA PnP support into
-your kernel, or disabled the driver's usage of it by setting the
-isapnp parameter as discussed above, then you will need to do some
-manual configuration.  There are two ways of doing this.  The most
-common is to use the isapnptools package to initialize the card, and
-use the kernel module form of the sound subsystem and sound drivers.
-Alternatively, some BIOS's allow manual configuration of installed
-PnP devices in a BIOS menu, which should allow using the non-modular
-sound drivers, i.e. built into the kernel.
-
-I personally use isapnp and modules, and do not have access to a PnP
-BIOS machine to test.  If you have such a beast, configuring the
-driver to be built into the kernel should just work (thanks to work
-done by David Luyer <luyer@ucs.uwa.edu.au>).  You will still need
-to specify settings, which can be done by adding:
-
-opl3sa2=<io>,<irq>,<dma>,<dma2>,<mssio>,<mpuio>
-
-to the kernel command line.  For example:
-
-opl3sa2=0x370,5,0,1,0x530,0x330
-
-If you are instead using the isapnp tools (as most people have been
-before Linux 2.4.x), follow the directions in their documentation to
-produce a configuration file.  Here is the relevant excerpt I used to
-use for my SA3 card from my isapnp.conf:
-
-(CONFIGURE YMH0800/-1 (LD 0
-
-# NOTE: IO 0 is for the unused SoundBlaster part of the chipset.
-(IO 0 (BASE 0x0220))
-(IO 1 (BASE 0x0530))
-(IO 2 (BASE 0x0388))
-(IO 3 (BASE 0x0330))
-(IO 4 (BASE 0x0370))
-(INT 0 (IRQ 5 (MODE +E)))
-(DMA 0 (CHANNEL 0))
-(DMA 1 (CHANNEL 1))
-
-Here, note that:
-
-Port  Acceptable Range  Purpose
-----  ----------------  -------
-IO 0  0x0220 - 0x0280   SB base address, unused.
-IO 1  0x0530 - 0x0F48   MSS base address
-IO 2  0x0388 - 0x03F8   OPL3 base address
-IO 3  0x0300 - 0x0334   MPU base address
-IO 4  0x0100 - 0x0FFE   card's own base address for its control I/O ports
-
-The IRQ and DMA values can be any that are considered acceptable for a
-MSS.  Assuming you've got isapnp all happy, then you should be able to
-do something like the following (which matches up with the isapnp
-configuration above):
-
-modprobe mpu401
-modprobe ad1848
-modprobe opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=5 dma=0 dma2=1
-modprobe opl3 io=0x388
-
-See the section "Automatic Module Loading" below for how to set up
-/etc/modprobe.conf to automate this.
-
-An important thing to remember that the opl3sa2 module's io argument is
-for it's own control port, which handles the card's master mixer for
-volume (on all cards), and bass and treble (on SA3 cards).
-
-
-Troubleshooting
----------------
-
-If all goes well and you see no error messages, you should be able to
-start using the sound capabilities of your system.  If you get an
-error message while trying to insert the opl3sa2 module, then make
-sure that the values of the various arguments match what you specified
-in your isapnp configuration file, and that there is no conflict with
-another device for an I/O port or interrupt.  Checking the contents of
-/proc/ioports and /proc/interrupts can be useful to see if you're
-butting heads with another device.
-
-If you still cannot get the module to load, look at the contents of
-your system log file, usually /var/log/messages.  If you see the
-message "opl3sa2: Unknown Yamaha audio controller version", then you
-have a different chipset version than I've encountered so far.  Look
-for all messages in the log file that start with "opl3sa2: " and see
-if they provide any clues.  If you do not see the chipset version
-message, and none of the other messages present in the system log are
-helpful, email me some details and I'll try my best to help.
-
-
-Automatic Module Loading
-------------------------
-
-Lastly, if you're using modules and want to set up automatic module
-loading with kmod, the kernel module loader, here is the section I
-currently use in my modprobe.conf file:
-
-# Sound
-alias sound-slot-0 opl3sa2
-options opl3sa2 io=0x370 mss_io=0x530 mpu_io=0x330 irq=7 dma=0 dma2=3
-options opl3 io=0x388
-
-That's all it currently takes to get an OPL3-SA3 card working on my
-system.  Once again, if you have any other problems, email me at the
-address listed above.

-Running sound cards on VIA chipsets
-
-o	There are problems with VIA chipsets and sound cards that appear to
-	lock the hardware solidly. Test programs under DOS have verified the
-	problem exists on at least some (but apparently not all) VIA boards
-
-o	VIA have so far failed to bother to answer support mail on the subject
-	so if you are a VIA engineer feeling aggrieved as you read this 
-	document go chase your own people. If there is a workaround please
-	let us know so we can implement it.
-
-
-Certain patterns of ISA DMA access used for most PC sound cards cause the
-VIA chipsets to lock up. From the collected reports this appears to cover a
-wide range of boards. Some also lock up with sound cards under Win* as well.
-
-Linux implements a workaround providing your chipset is PCI and you compiled
-with PCI Quirks enabled. If so you will see a message
-	"Activating ISA DMA bug workarounds"
-
-during booting. If you have a VIA PCI chipset that hangs when you use the
-sound and is not generating this message even with PCI quirks enabled
-please report the information to the linux-kernel list (see REPORTING-BUGS).
-
-If you are one of the tiny number of unfortunates with a 486 ISA/VLB VIA
-chipset board you need to do the following to build a special kernel for
-your board
-
-	edit linux/include/asm-i386/dma.h
-
-change
-
-#define isa_dma_bridge_buggy 	(0)
-
-to

-#define isa_dma_bridge_buggy 	(1)
-
-and rebuild a kernel without PCI quirk support.
-
-
-Other than this particular glitch the VIA [M]VP* chipsets appear to work
-perfectly with Linux.

-Documentation for the Cirrus Logic/Crystal SoundFusion cs46xx/cs4280 audio

-
-The cs46xx audio driver supports the DSP line of Cirrus controllers. 
-Specifically, the cs4610, cs4612, cs4614, cs4622, cs4624, cs4630 and the cs4280
-products.  This driver uses the generic ac97_codec driver for AC97 codec
-support.  
-
-
-Features:
-
-Full Duplex Playback/Capture supported from 8k-48k.
-16Bit Signed LE & 8Bit Unsigned, with Mono or Stereo supported.
-
-APM/PM - 2.2.x PM is enabled and functional. APM can also
-be enabled for 2.4.x by modifying the CS46XX_ACPI_SUPPORT macro
-definition.
-
-DMA playback buffer size is configurable from 16k (defaultorder=2) up to 2Meg 
-(defaultorder=11).  DMA capture buffer size is fixed at a single 4k page as
-two 2k fragments.
-
-MMAP seems to work well with QuakeIII, and test XMMS plugin.
-
-Myth2 works, but the polling logic is not fully correct, but is functional.
-
-The 2.4.4-ac6 gameport code in the cs461x joystick driver has been tested 
-with a Microsoft Sidewinder joystick (cs461x.o and sidewinder.o).  This 
-audio driver must be loaded prior to the joystick driver to enable the
-DSP task image supporting the joystick device.
-
-
-Limitations:
-
-SPDIF is currently not supported.
-
-Primary codec support only.  No secondary codec support is implemented.
-
-
-
-NOTES:
-
-Hercules Game Theatre XP - the EGPIO2 pin controls the external Amp,
-and has been tested.
-Module parameter hercules_egpio_disable set to 1, will force a 0 to EGPIODR
-to disable the external amplifier.
-
-VTB Santa Cruz - the GPIO7/GPIO8 on the Secondary Codec control
-the external amplifier for the "back" speakers, since we do not
-support the secondary codec then this external amp is not
-turned on.  The primary codec external amplifier is supported but
-note that the AC97 EAPD bit is inverted logic (amp_voyetra()).
-
-DMA buffer size - there are issues with many of the Linux applications
-concerning the optimal buffer size.  Several applications request a 
-certain fragment size and number and then do not verify that the driver
-has the ability to support the requested configuration.  
-SNDCTL_DSP_SETFRAGMENT ioctl is used to request a fragment size and
-number of fragments.  Some applications exit if an error is returned
-on this particular ioctl. Therefore, in alignment with the other OSS audio 
-drivers, no error is returned when a SETFRAGs IOCTL is received, but the 
-values passed from the app are not used in any buffer calculation 
-(ossfragshift/ossmaxfrags are not used).
-Use the "defaultorder=N" module parameter to change the buffer size if
-you have an application that requires a specific number of fragments
-or a specific buffer size (see below).
-
-Debug Interface
----------------
-There is an ioctl debug interface to allow runtime modification of the 
-debug print levels.  This debug interface code can be disabled from the 
-compilation process with commenting the following define:
-#define CSDEBUG_INTERFACE 1
-There is also a debug print methodolgy to select printf statements from
-different areas of the driver.  A debug print level is also used to allow
-additional printfs to be active.  Comment out the following line in the
-driver to disable compilation of the CS_DBGOUT print statements:
-#define CSDEBUG 1
- 
-Please see the definitions for cs_debuglevel and cs_debugmask for additional
-information on the debug levels and sections.

+spi_lm70llp :  LM70-LLP parport-to-SPI adapter
+==============================================
+
+Supported board/chip:
+  * National Semiconductor LM70 LLP evaluation board
+    Datasheet: http://www.national.com/pf/LM/LM70.html
+
+Author:
+        Kaiwan N Billimoria <kaiwan@designergraphix.com>
+
+Description
+-----------
+This driver provides glue code connecting a National Semiconductor LM70 LLP
+temperature sensor evaluation board to the kernel's SPI core subsystem.
+
+In effect, this driver turns the parallel port interface on the eval board
+into a SPI bus with a single device, which will be driven by the generic
+LM70 driver (drivers/hwmon/lm70.c).
+
+The hardware interfacing on the LM70 LLP eval board is as follows:
+
+   Parallel                 LM70 LLP
+     Port      Direction   JP2 Header
+   ----------- --------- ----------------
+      D0     2      -         -
+      D1     3     -->      V+   5
+      D2     4     -->      V+   5
+      D3     5     -->      V+   5
+      D4     6     -->      V+   5
+      D5     7     -->      nCS  8
+      D6     8     -->      SCLK 3
+      D7     9     -->      SI/O 5
+     GND    25      -       GND  7
+    Select  13     <--      SI/O 1
+   ----------- --------- ----------------
+
+Note that since the LM70 uses a "3-wire" variant of SPI, the SI/SO pin
+is connected to both pin D7 (as Master Out) and Select (as Master In)
+using an arrangment that lets either the parport or the LM70 pull the
+pin low.  This can't be shared with true SPI devices, but other 3-wire
+devices might share the same SI/SO pin.
+
+The bitbanger routine in this driver (lm70_txrx) is called back from
+the bound "hwmon/lm70" protocol driver through its sysfs hook, using a
+spi_write_then_read() call.  It performs Mode 0 (SPI/Microwire) bitbanging.
+The lm70 driver then inteprets the resulting digital temperature value
+and exports it through sysfs.
+
+A "gotcha": National Semiconductor's LM70 LLP eval board circuit schematic
+shows that the SI/O line from the LM70 chip is connected to the base of a
+transistor Q1 (and also a pullup, and a zener diode to D7); while the
+collector is tied to VCC.
+
+Interpreting this circuit, when the LM70 SI/O line is High (or tristate
+and not grounded by the host via D7), the transistor conducts and switches
+the collector to zero, which is reflected on pin 13 of the DB25 parport
+connector.  When SI/O is Low (driven by the LM70 or the host) on the other
+hand, the transistor is cut off and the voltage tied to it's collector is
+reflected on pin 13 as a High level.
+
+So: the getmiso inline routine in this driver takes this fact into account,
+inverting the value read at pin 13.
+
+
+Thanks to
+---------
+o David Brownell for mentoring the SPI-side driver development.
+o Dr.Craig Hollabaugh for the (early) "manual" bitbanging driver version.
+o Nadir Billimoria for help interpreting the circuit schematic.

+Emergency operations:
+---------------------
+
+Minimal debugging (sanity checks alone) can be enabled by booting with
+
+	slub_debug=F
+
+This will be generally be enough to enable the resiliency features of slub
+which will keep the system running even if a bad kernel component will
+keep corrupting objects. This may be important for production systems.
+Performance will be impacted by the sanity checks and there will be a
+continual stream of error messages to the syslog but no additional memory
+will be used (unlike full debugging).
+
+No guarantees. The kernel component still needs to be fixed. Performance
+may be optimized further by locating the slab that experiences corruption
+and enabling debugging only for that cache
+
+I.e.
+
+	slub_debug=F,dentry
+
+If the corruption occurs by writing after the end of the object then it
+may be advisable to enable a Redzone to avoid corrupting the beginning
+of other objects.

-Notes:
-
-The major number for SLM printers is 28 (like ACSI), but as a character
-device, not block device. The minor number is the number of the printer (if
-you have more than one SLM; currently max. 2 (#define-constant) SLMs are
-supported). The device can be opened for reading and writing. If reading it,
-you get some status infos (MODE SENSE data). Writing mode is used for the data
-to be printed. Some ioctls allow to get the printer status and to tune printer
-modes and some internal variables.
-
-A special problem of the SLM driver is the timing and thus the buffering of
-the print data. The problem is that all the data for one page must be present
-in memory when printing starts, else --when swapping occurs-- the timing could
-not be guaranteed. There are several ways to assure this:
-
- 1) Reserve a buffer of 1196k (maximum page size) statically by
-    atari_stram_alloc(). The data are collected there until they're complete,
-	and then printing starts. Since the buffer is reserved, no further
-	considerations about memory and swapping are needed. So this is the
-	simplest method, but it needs a lot of memory for just the SLM.
-
-    An striking advantage of this method is (supposed the SLM_CONT_CNT_REPROG
-	method works, see there), that there are no timing problems with the DMA
-	anymore.
-	
- 2) The other method would be to reserve the buffer dynamically each time
-    printing is required. I could think of looking at mem_map where the
-	largest unallocted ST-RAM area is, taking the area, and then extending it
-	by swapping out the neighbored pages, until the needed size is reached.
-	This requires some mm hacking, but seems possible. The only obstacle could
-	be pages that cannot be swapped out (reserved pages)...
-
- 3) Another possibility would be to leave the real data in user space and to
-    work with two dribble buffers of about 32k in the driver: While the one
-	buffer is DMAed to the SLM, the other can be filled with new data. But
-	to keep the timing, that requires that the user data remain in memory and
-	are not swapped out. Requires mm hacking, too, but maybe not so bad as
-	method 2).

+/*
+ * The SystemACE chip is designed to configure FPGAs by loading an FPGA
+ * bitstream from a file on a CF card and squirting it into FPGAs connected
+ * to the SystemACE JTAG chain.  It also has the advantage of providing an
+ * MPU interface which can be used to control the FPGA configuration process
+ * and to use the attached CF card for general purpose storage.
+ *
+ * This driver is a block device driver for the SystemACE.
+ *
+ * Initialization:
+ *    The driver registers itself as a platform_device driver at module
+ *    load time.  The platform bus will take care of calling the
+ *    ace_probe() method for all SystemACE instances in the system.  Any
+ *    number of SystemACE instances are supported.  ace_probe() calls
+ *    ace_setup() which initialized all data structures, reads the CF
+ *    id structure and registers the device.
+ *
+ * Processing:
+ *    Just about all of the heavy lifting in this driver is performed by
+ *    a Finite State Machine (FSM).  The driver needs to wait on a number
+ *    of events; some raised by interrupts, some which need to be polled
+ *    for.  Describing all of the behaviour in a FSM seems to be the
+ *    easiest way to keep the complexity low and make it easy to
+ *    understand what the driver is doing.  If the block ops or the
+ *    request function need to interact with the hardware, then they
+ *    simply need to flag the request and kick of FSM processing.
+ *
+ *    The FSM itself is atomic-safe code which can be run from any
+ *    context.  The general process flow is:
+ *    1. obtain the ace->lock spinlock.
+ *    2. loop on ace_fsm_dostate() until the ace->fsm_continue flag is
+ *       cleared.
+ *    3. release the lock.
+ *
+ *    Individual states do not sleep in any way.  If a condition needs to
+ *    be waited for then the state much clear the fsm_continue flag and
+ *    either schedule the FSM to be run again at a later time, or expect
+ *    an interrupt to call the FSM when the desired condition is met.
+ *
+ *    In normal operation, the FSM is processed at interrupt context
+ *    either when the driver's tasklet is scheduled, or when an irq is
+ *    raised by the hardware.  The tasklet can be scheduled at any time.
+ *    The request method in particular schedules the tasklet when a new
+ *    request has been indicated by the block layer.  Once started, the
+ *    FSM proceeds as far as it can processing the request until it
+ *    needs on a hardware event.  At this point, it must yield execution.
+ *
+ *    A state has two options when yielding execution:
+ *    1. ace_fsm_yield()
+ *       - Call if need to poll for event.
+ *       - clears the fsm_continue flag to exit the processing loop
+ *       - reschedules the tasklet to run again as soon as possible
+ *    2. ace_fsm_yieldirq()
+ *       - Call if an irq is expected from the HW
+ *       - clears the fsm_continue flag to exit the processing loop
+ *       - does not reschedule the tasklet so the FSM will not be processed
+ *         again until an irq is received.
+ *    After calling a yield function, the state must return control back
+ *    to the FSM main loop.
+ *
+ *    Additionally, the driver maintains a kernel timer which can process
+ *    the FSM.  If the FSM gets stalled, typically due to a missed
+ *    interrupt, then the kernel timer will expire and the driver can
+ *    continue where it left off.
+ *
+ * To Do:
+ *    - Add FPGA configuration control interface.
+ *    - Request major number from lanana

-/* bionet.c     BioNet-100 device driver for linux68k.
- *
- * Version:	@(#)bionet.c	1.0	02/06/96
- *
- * Author:	Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and		Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
- * Some changes in bionet_poll_rx by Karl-Heinz Lohner
- *
-	What is it ?
-	------------
-	This driver controls the BIONET-100 LAN-Adapter which connects
-	an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
-	This version can be compiled as a loadable module (See the
-	compile command at the bottom of this file).
-	At load time, you can optionally set the debugging level and the
-	fastest response time on the command line of 'insmod'.
-
-	'bionet_debug'
-		controls the amount of diagnostic messages:
-	  0  : no messages
-	  >0 : see code for meaning of printed messages
-
-	'bionet_min_poll_time' (always >=1)
-		gives the time (in jiffies) between polls. Low values
-		increase the system load (beware!)
-
-	When loaded, a net device with the name 'bio0' becomes available,
-	which can be controlled with the usual 'ifconfig' command.
-
-	It is possible to compile this driver into the kernel like other
-	(net) drivers. For this purpose, some source files (e.g. config-files
-	makefiles, Space.c) must be changed accordingly. (You may refer to
-	other drivers how to do it.) In this case, the device will be detected
-	at boot time and (probably) appear as 'eth0'.
-
-	This code is based on several sources:
-	- The driver code for a parallel port ethernet adapter by
-	  Donald Becker (see file 'atp.c' from the PC linux distribution)
-	- The ACSI code by Roman Hodek for the ATARI-ACSI harddisk support
-	  and DMA handling.
-	- Very limited information about moving packets in and out of the
-	  BIONET-adapter from the TCP package for TOS by BioData GmbH.
-
-	Theory of Operation
-	-------------------
-	Because the ATARI DMA port is usually shared between several
-	devices (eg. harddisk, floppy) we cannot block the ACSI bus
-	while waiting for interrupts. Therefore we use a polling mechanism
-	to fetch packets from the adapter. For the same reason, we send
-	packets without checking that the previous packet has been sent to
-	the LAN. We rely on the higher levels of the networking code to detect
-	missing packets and resend them.
-
-	Before we access the ATARI DMA controller, we check if another
-	process is using the DMA. If not, we lock the DMA, perform one or
-	more packet transfers and unlock the DMA before returning.
-	We do not use 'stdma_lock' unconditionally because it is unclear
-	if the networking code can be set to sleep, which will happen if
-	another (possibly slow) device is using the DMA controller.
-
-	The polling is done via timer interrupts which periodically
-	'simulate' an interrupt from the Ethernet adapter. The time (in jiffies)
-	between polls varies depending on an estimate of the net activity.
-	The allowed range is given by the variable 'bionet_min_poll_time'
-	for the lower (fastest) limit and the constant 'MAX_POLL_TIME'
-	for the higher (slowest) limit.
-
-	Whenever a packet arrives, we switch to fastest response by setting
-	the polling time to its lowest limit. If the following poll fails,
-	because no packets have arrived, we increase the time for the next
-	poll. When the net activity is low, the polling time effectively
-	stays at its maximum value, resulting in the lowest load for the
-	machine.

-/* atari_pamsnet.c     PAMsNet device driver for linux68k.
- *
- * Version:	@(#)PAMsNet.c	0.2ß	03/31/96
- *
- * Author:  Torsten Lang <Torsten.Lang@ap.physik.uni-giessen.de>
- *                       <Torsten.Lang@jung.de>
- *
- * This driver is based on my driver PAMSDMA.c for MiNT-Net and
- * on the driver bionet.c written by
- *          Hartmut Laue <laue@ifk-mp.uni-kiel.de>
- * and      Torsten Narjes <narjes@ifk-mp.uni-kiel.de>
- *
- * Little adaptions for integration into pl7 by Roman Hodek
- *
-	What is it ?
-	------------
-	This driver controls the PAMsNet LAN-Adapter which connects
-	an ATARI ST/TT via the ACSI-port to an Ethernet-based network.
-
-	This version can be compiled as a loadable module (See the
-	compile command at the bottom of this file).
-	At load time, you can optionally set the debugging level and the
-	fastest response time on the command line of 'insmod'.
-
-	'pamsnet_debug'
-		controls the amount of diagnostic messages:
-	  0  : no messages
-	  >0 : see code for meaning of printed messages
-
-	'pamsnet_min_poll_time' (always >=1)
-		gives the time (in jiffies) between polls. Low values
-		increase the system load (beware!)
-
-	When loaded, a net device with the name 'eth?' becomes available,
-	which can be controlled with the usual 'ifconfig' command.
-
-	It is possible to compile this driver into the kernel like other
-	(net) drivers. For this purpose, some source files (e.g. config-files
-	makefiles, Space.c) must be changed accordingly. (You may refer to
-	other drivers how to do it.) In this case, the device will be detected
-	at boot time and (probably) appear as 'eth0'.
-
-	Theory of Operation
-	-------------------
-	Because the ATARI DMA port is usually shared between several
-	devices (eg. harddisk, floppy) we cannot block the ACSI bus
-	while waiting for interrupts. Therefore we use a polling mechanism
-	to fetch packets from the adapter. For the same reason, we send
-	packets without checking that the previous packet has been sent to
-	the LAN. We rely on the higher levels of the networking code to detect
-	missing packets and resend them.
-
-	Before we access the ATARI DMA controller, we check if another
-	process is using the DMA. If not, we lock the DMA, perform one or
-	more packet transfers and unlock the DMA before returning.
-	We do not use 'stdma_lock' unconditionally because it is unclear
-	if the networking code can be set to sleep, which will happen if
-	another (possibly slow) device is using the DMA controller.
-
-	The polling is done via timer interrupts which periodically
-	'simulate' an interrupt from the Ethernet adapter. The time (in jiffies)
-	between polls varies depending on an estimate of the net activity.
-	The allowed range is given by the variable 'bionet_min_poll_time'
-	for the lower (fastest) limit and the constant 'MAX_POLL_TIME'
-	for the higher (slowest) limit.
-
-	Whenever a packet arrives, we switch to fastest response by setting
-	the polling time to its lowest limit. If the following poll fails,
-	because no packets have arrived, we increase the time for the next
-	poll. When the net activity is low, the polling time effectively
-	stays at its maximum value, resulting in the lowest load for the
-	machine.

- * Definitions of commands understood by the PAMs DMA adaptor.
- *
- * In general the DMA adaptor uses LUN 0, 5, 6 and 7 on one ID changeable
- * by the PAM's Net software.
- *
- * LUN 0 works as a harddisk. You can boot the PAM's Net driver there.
- * LUN 5 works as a harddisk and lets you access the RAM and some I/O HW
- *       area. In sector 0, bytes 0x38-0x3d you find the ethernet HW address
- *       of the adaptor.
- * LUN 6 works as a harddisk and lets you access the firmware ROM.
- * LUN 7 lets you send and receive packets.
- *
- * Some commands like the INQUIRY command work identical on all used LUNs.
- *
- * UNKNOWN1 seems to read some data.
- *          Command length is 6 bytes.
- * UNKNOWN2 seems to read some data (command byte 1 must be !=0). The
- *          following bytes seem to be something like an allocation length.
- *          Command length is 6 bytes.
- * READPKT  reads a packet received by the DMA adaptor.
- *          Command length is 6 bytes.
- * WRITEPKT sends a packet transferred by the following DMA phase. The length
- *          of the packet is transferred in command bytes 3 and 4.
- *          The adaptor automatically replaces the src hw address in an ethernet
- *          packet by its own hw address.
- *          Command length is 6 bytes.
- * INQUIRY  has the same function as the INQUIRY command supported by harddisks
- *          and other SCSI devices. It lets you detect which device you found
- *          at a given address.
- *          Command length is 6 bytes.
- * START    initializes the DMA adaptor. After this command it is able to send
- *          and receive packets. There is no status byte returned!
- *          Command length is 1 byte.
- * NUMPKTS  gives back the number of received packets waiting in the queue in
- *          the status byte.
- *          Command length is 1 byte.
- * UNKNOWN3
- * UNKNOWN4 Function of these three commands is unknown.
- * UNKNOWN5 The command length of these three commands is 1 byte.
- * DESELECT immediately deselects the DMA adaptor. May important with interrupt
- *          driven operation.
- *          Command length is 1 byte.
- * STOP     resets the DMA adaptor. After this command packets can no longer
- *          be received or transferred.
- *          Command length is 6 byte.

- *
- *   OPTION_NO_ASYNC
- *	Don't negotiate for asynchronous transfers on the first command 
- *	when OPTION_ALWAYS_SYNCHRONOUS is set.  Useful for dain bramaged
- *	devices which do something bad rather than sending a MESSAGE 
- *	REJECT back to us like they should if they can't cope.
- *
- *   OPTION_SYNCHRONOUS
- *	Enable support for synchronous transfers.  Target negotiated 
- *	synchronous transfers will be responded to.  To initiate 
- *	a synchronous transfer request,  call 
- *
- *	    request_synchronous (hostno, target) 
- *
- *	from within KGDB.
- *
- *   OPTION_ALWAYS_SYNCHRONOUS
- *	Negotiate for synchronous transfers with every target after
- *	driver initialization or a SCSI bus reset.  This is a bit dangerous, 
- *	since there are some dain bramaged SCSI devices which will accept
- *	SDTR messages but keep talking asynchronously.
- *
- *   OPTION_DISCONNECT
- *	Enable support for disconnect/reconnect.  To change the 
- *	default setting on a given host adapter, call
- *
- *	    request_disconnect (hostno, allow)
- *
- *	where allow is non-zero to allow, 0 to disallow.

- *  If you really want to run 10MHz FAST SCSI-II transfers, you should 
- *  know that the NCR driver currently ignores parity information.  Most
- *  systems do 5MHz SCSI fine.  I've seen a lot that have problems faster
- *  than 8MHz.  To play it safe, we only request 5MHz transfers.
- *
- *  If you'd rather get 10MHz transfers, edit sdtr_message and change 
- *  the fourth byte from 50 to 25.

-/*
- * Design issues : 
- * The cumulative latency needed to propagate a read/write request 
- * through the file system, buffer cache, driver stacks, SCSI host, and 
- * SCSI device is ultimately the limiting factor in throughput once we 
- * have a sufficiently fast host adapter.
- *  
- * So, to maximize performance we want to keep the ratio of latency to data 
- * transfer time to a minimum by
- * 1.  Minimizing the total number of commands sent (typical command latency
- *	including drive and bus mastering host overhead is as high as 4.5ms)
- *	to transfer a given amount of data.  
- *
- *      This is accomplished by placing no arbitrary limit on the number
- *	of scatter/gather buffers supported, since we can transfer 1K
- *	per scatter/gather buffer without Eric's cluster patches, 
- *	4K with.  
- *
- * 2.  Minimizing the number of fatal interrupts serviced, since
- * 	fatal interrupts halt the SCSI I/O processor.  Basically,
- *	this means offloading the practical maximum amount of processing 
- *	to the SCSI chip.
- * 
- *	On the NCR53c810/820/720,  this is accomplished by using 
- *		interrupt-on-the-fly signals when commands complete, 
- *		and only handling fatal errors and SDTR / WDTR 	messages 
- *		in the host code.
- *
- *	On the NCR53c710, interrupts are generated as on the NCR53c8x0,
- *		only the lack of a interrupt-on-the-fly facility complicates
- *		things.   Also, SCSI ID registers and commands are 
- *		bit fielded rather than binary encoded.
- *		
- * 	On the NCR53c700 and NCR53c700-66, operations that are done via 
- *		indirect, table mode on the more advanced chips must be
- *	        replaced by calls through a jump table which 
- *		acts as a surrogate for the DSA.  Unfortunately, this 
- * 		will mean that we must service an interrupt for each 
- *		disconnect/reconnect.
- * 
- * 3.  Eliminating latency by pipelining operations at the different levels.
- * 	
- *	This driver allows a configurable number of commands to be enqueued
- *	for each target/lun combination (experimentally, I have discovered
- *	that two seems to work best) and will ultimately allow for 
- *	SCSI-II tagged queuing.
- * 	
- *
- * Architecture : 
- * This driver is built around a Linux queue of commands waiting to 
- * be executed, and a shared Linux/NCR array of commands to start.  Commands
- * are transferred to the array  by the run_process_issue_queue() function 
- * which is called whenever a command completes.
- *
- * As commands are completed, the interrupt routine is triggered,
- * looks for commands in the linked list of completed commands with
- * valid status, removes these commands from a list of running commands, 
- * calls the done routine, and flags their target/luns as not busy.
- *
- * Due to limitations in the intelligence of the NCR chips, certain
- * concessions are made.  In many cases, it is easier to dynamically 
- * generate/fix-up code rather than calculate on the NCR at run time.  
- * So, code is generated or fixed up for
- *
- * - Handling data transfers, using a variable number of MOVE instructions
- *	interspersed with CALL MSG_IN, WHEN MSGIN instructions.
- *
- * 	The DATAIN and DATAOUT routines	are separate, so that an incorrect
- *	direction can be trapped, and space isn't wasted. 
- *
- *	It may turn out that we're better off using some sort 
- *	of table indirect instruction in a loop with a variable
- *	sized table on the NCR53c710 and newer chips.
- *
- * - Checking for reselection (NCR53c710 and better)
- *
- * - Handling the details of SCSI context switches (NCR53c710 and better),
- *	such as reprogramming appropriate synchronous parameters, 
- *	removing the dsa structure from the NCR's queue of outstanding
- *	commands, etc.

- * KNOWN BUGS :
- * - There is some sort of conflict when the PPP driver is compiled with 
- * 	support for 16 channels?
- * 
- * - On systems which predate the 1.3.x initialization order change,
- *      the NCR driver will cause Cannot get free page messages to appear.  
- *      These are harmless, but I don't know of an easy way to avoid them.
- *
- * - With OPTION_DISCONNECT, on two systems under unknown circumstances,
- *	we get a PHASE MISMATCH with DSA set to zero (suggests that we 
- *	are occurring somewhere in the reselection code) where 
- *	DSP=some value DCMD|DBC=same value.  
- * 	
- *	Closer inspection suggests that we may be trying to execute
- *	some portion of the DSA?
- * scsi0 : handling residual transfer (+ 0 bytes from DMA FIFO)
- * scsi0 : handling residual transfer (+ 0 bytes from DMA FIFO)
- * scsi0 : no current command : unexpected phase MSGIN.
- *         DSP=0x1c46cc, DCMD|DBC=0x1c46ac, DSA=0x0
- *         DSPS=0x0, TEMP=0x1c3e70, DMODE=0x80

- *	Changed the print code in the phase_mismatch handler so

-
-/* 
- * Possible future direction of architecture for max performance :
- *
- * We're using a single start array for the NCR chip.  This is 
- * sub-optimal, because we cannot add a command which would conflict with 
- * an executing command to this start queue, and therefore must insert the 
- * next command for a given I/T/L combination after the first has completed;
- * incurring our interrupt latency between SCSI commands.
- *
- * To allow further pipelining of the NCR and host CPU operation, we want 
- * to set things up so that immediately on termination of a command destined 
- * for a given LUN, we get that LUN busy again.  
- * 
- * To do this, we need to add a 32 bit pointer to which is jumped to 
- * on completion of a command.  If no new command is available, this 
- * would point to the usual DSA issue queue select routine.
- *
- * If one were, it would point to a per-NCR53c7x0_cmd select routine 
- * which starts execution immediately, inserting the command at the head 
- * of the start queue if the NCR chip is selected or reselected.
- *
- * We would change so that we keep a list of outstanding commands 
- * for each unit, rather than a single running_list.  We'd insert 
- * a new command into the right running list; if the NCR didn't 
- * have something running for that yet, we'd put it in the 
- * start queue as well.  Some magic needs to happen to handle the 
- * race condition between the first command terminating before the 
- * new one is written.
- *
- * Potential for profiling : 
- * Call do_gettimeofday(struct timeval *tv) to get 800ns resolution.

-
-
-/*
- * TODO : 
- * 1.  To support WIDE transfers, not much needs to happen.  We
- *	should do CHMOVE instructions instead of MOVEs when
- *	we have scatter/gather segments of uneven length.  When
- * 	we do this, we need to handle the case where we disconnect
- *	between segments.
- * 
- * 2.  Currently, when Icky things happen we do a FATAL().  Instead,
- *     we want to do an integrity check on the parts of the NCR hostdata
- *     structure which were initialized at boot time; FATAL() if that 
- *     fails, and otherwise try to recover.  Keep track of how many
- *     times this has happened within a single SCSI command; if it 
- *     gets excessive, then FATAL().
- *
- * 3.  Parity checking is currently disabled, and a few things should 
- *     happen here now that we support synchronous SCSI transfers :
- *     1.  On soft-reset, we shoould set the EPC (Enable Parity Checking)
- *	   and AAP (Assert SATN/ on parity error) bits in SCNTL0.
- *	
- *     2.  We should enable the parity interrupt in the SIEN0 register.
- * 
- *     3.  intr_phase_mismatch() needs to believe that message out is 
- *	   always an "acceptable" phase to have a mismatch in.  If 
- *	   the old phase was MSG_IN, we should send a MESSAGE PARITY 
- *	   error.  If the old phase was something else, we should send
- *	   a INITIATOR_DETECTED_ERROR message.  Note that this could
- *	   cause a RESTORE POINTERS message; so we should handle that 
- *	   correctly first.  Instead, we should probably do an 
- *	   initiator_abort.
- *
- * 4.  MPEE bit of CTEST4 should be set so we get interrupted if 
- *     we detect an error.
- *
- *  
- * 5.  The initial code has been tested on the NCR53c810.  I don't 
- *     have access to NCR53c700, 700-66 (Forex boards), NCR53c710
- *     (NCR Pentium systems), NCR53c720, NCR53c820, or NCR53c825 boards to 
- *     finish development on those platforms.
- *
- *     NCR53c820/825/720 - need to add wide transfer support, including WDTR 
- *     		negotiation, programming of wide transfer capabilities
- *		on reselection and table indirect selection.
- *
- *     NCR53c710 - need to add fatal interrupt or GEN code for 
- *		command completion signaling.   Need to modify all 
- *		SDID, SCID, etc. registers, and table indirect select code 
- *		since these use bit fielded (ie 1<<target) instead of 
- *		binary encoded target ids.  Need to accommodate
- *		different register mappings, probably scan through
- *		the SCRIPT code and change the non SFBR register operand
- *		of all MOVE instructions.
- *
- *		It is rather worse than this actually, the 710 corrupts
- *		both TEMP and DSA when you do a MOVE MEMORY.  This
- *		screws you up all over the place.  MOVE MEMORY 4 with a
- *		destination of DSA seems to work OK, which helps some.
- *		Richard Hirst  richard@sleepie.demon.co.uk
- * 
- *     NCR53c700/700-66 - need to add code to refix addresses on 
- *		every nexus change, eliminate all table indirect code,
- *		very messy.
- *
- * 6.  The NCR53c7x0 series is very popular on other platforms that 
- *     could be running Linux - ie, some high performance AMIGA SCSI 
- *     boards use it.  
- *	
- *     So, I should include #ifdef'd code so that it is 
- *     compatible with these systems.
- *	
- *     Specifically, the little Endian assumptions I made in my 
- *     bit fields need to change, and if the NCR doesn't see memory
- *     the right way, we need to provide options to reverse words
- *     when the scripts are relocated.
- *
- * 7.  Use vremap() to access memory mapped boards.

-
-/* 
- * Allow for simultaneous existence of multiple SCSI scripts so we 
- * can have a single driver binary for all of the family.
- *
- * - one for NCR53c700 and NCR53c700-66 chips	(not yet supported)
- * - one for rest (only the NCR53c810, 815, 820, and 825 are currently 
- *	supported)
- * 
- * So that we only need two SCSI scripts, we need to modify things so
- * that we fixup register accesses in READ/WRITE instructions, and

-; IMPORTANT : This code is self modifying due to the limitations of 
-;	the NCR53c7,8xx series chips.  Persons debugging this code with
-;	the remote debugger should take this into account, and NOT set
-;	breakpoints in modified instructions.
-;
-; Design:
-; The NCR53c7,8xx family of SCSI chips are busmasters with an onboard 
-; microcontroller using a simple instruction set.   
-;
-; So, to minimize the effects of interrupt latency, and to maximize 
-; throughput, this driver offloads the practical maximum amount 
-; of processing to the SCSI chip while still maintaining a common
-; structure.
-;
-; Where tradeoffs were needed between efficiency on the older
-; chips and the newer NCR53c800 series, the NCR53c800 series 
-; was chosen.
-;
-; While the NCR53c700 and NCR53c700-66 lacked the facilities to fully
-; automate SCSI transfers without host processor intervention, this 
-; isn't the case with the NCR53c710 and newer chips which allow 
-;
-; - reads and writes to the internal registers from within the SCSI
-; 	scripts, allowing the SCSI SCRIPTS(tm) code to save processor
-; 	state so that multiple threads of execution are possible, and also
-; 	provide an ALU for loop control, etc.
-; 
-; - table indirect addressing for some instructions. This allows 
-;	pointers to be located relative to the DSA ((Data Structure
-;	Address) register.
-;
-; These features make it possible to implement a mailbox style interface,
-; where the same piece of code is run to handle I/O for multiple threads
-; at once minimizing our need to relocate code.  Since the NCR53c700/
-; NCR53c800 series have a unique combination of features, making a 
-; a standard ingoing/outgoing mailbox system, costly, I've modified it.
-;
-; - Mailboxes are a mixture of code and data.  This lets us greatly
-; 	simplify the NCR53c810 code and do things that would otherwise
-;	not be possible.
-;
-; The saved data pointer is now implemented as follows :
-;
-; 	Control flow has been architected such that if control reaches
-;	munge_save_data_pointer, on a restore pointers message or 
-;	reconnection, a jump to the address formerly in the TEMP register
-;	will allow the SCSI command to resume execution.
-;
-
-;
-; Note : the DSA structures must be aligned on 32 bit boundaries,
-; since the source and destination of MOVE MEMORY instructions 
-; must share the same alignment and this is the alignment of the
-; NCR registers.
-;
-
-; For some systems (MVME166, for example) dmode is always the same, so don't
-; waste time writing it

-; Once a device has initiated reselection, we need to compare it 
-; against the singly linked list of commands which have disconnected
-; and are pending reselection.  These commands are maintained in 
-; an unordered singly linked list of DSA structures, through the
-; DSA pointers at their 'centers' headed by the reconnect_dsa_head
-; pointer.
-; 
-; To avoid complications in removing commands from the list,
-; I minimize the amount of expensive (at eight operations per
-; addition @ 500-600ns each) pointer operations which must
-; be done in the NCR driver by precomputing them on the 
-; host processor during dsa structure generation.
-;
-; The fixed-up per DSA code knows how to recognize the nexus
-; associated with the corresponding SCSI command, and modifies
-; the source and destination pointers for the MOVE MEMORY 
-; instruction which is executed when reselected_ok is called
-; to remove the command from the list.  Similarly, DSA is 
-; loaded with the address of the next DSA structure and
-; reselected_check_next is called if a failure occurs.
-;
-; Perhaps more concisely, the net effect of the mess is 
-;
-; for (dsa = reconnect_dsa_head, dest = &reconnect_dsa_head,

-; IMPORTANT : This code is self modifying due to the limitations of 
-;	the NCR53c7,8xx series chips.  Persons debugging this code with
-;	the remote debugger should take this into account, and NOT set
-;	breakpoints in modified instructions.
-;
-; Design:
-; The NCR53c7,8xx family of SCSI chips are busmasters with an onboard 
-; microcontroller using a simple instruction set.   
-;
-; So, to minimize the effects of interrupt latency, and to maximize 
-; throughput, this driver offloads the practical maximum amount 
-; of processing to the SCSI chip while still maintaining a common
-; structure.
-;
-; Where tradeoffs were needed between efficiency on the older
-; chips and the newer NCR53c800 series, the NCR53c800 series 
-; was chosen.
-;
-; While the NCR53c700 and NCR53c700-66 lacked the facilities to fully
-; automate SCSI transfers without host processor intervention, this 
-; isn't the case with the NCR53c710 and newer chips which allow 
-;
-; - reads and writes to the internal registers from within the SCSI
-; 	scripts, allowing the SCSI SCRIPTS(tm) code to save processor
-; 	state so that multiple threads of execution are possible, and also
-; 	provide an ALU for loop control, etc.
-; 
-; - table indirect addressing for some instructions. This allows 
-;	pointers to be located relative to the DSA ((Data Structure
-;	Address) register.
-;
-; These features make it possible to implement a mailbox style interface,
-; where the same piece of code is run to handle I/O for multiple threads
-; at once minimizing our need to relocate code.  Since the NCR53c700/
-; NCR53c800 series have a unique combination of features, making a 
-; a standard ingoing/outgoing mailbox system, costly, I've modified it.
-;
-; - Mailboxes are a mixture of code and data.  This lets us greatly
-; 	simplify the NCR53c810 code and do things that would otherwise
-;	not be possible.
-;
-; The saved data pointer is now implemented as follows :
-;
-; 	Control flow has been architected such that if control reaches
-;	munge_save_data_pointer, on a restore pointers message or 
-;	reconnection, a jump to the address formerly in the TEMP register
-;	will allow the SCSI command to resume execution.
-;
-
-;
-; Note : the DSA structures must be aligned on 32 bit boundaries,
-; since the source and destination of MOVE MEMORY instructions 
-; must share the same alignment and this is the alignment of the
-; NCR registers.
-;
-
-; For some systems (MVME166, for example) dmode is always the same, so don't
-; waste time writing it

-; Once a device has initiated reselection, we need to compare it 
-; against the singly linked list of commands which have disconnected
-; and are pending reselection.  These commands are maintained in 
-; an unordered singly linked list of DSA structures, through the
-; DSA pointers at their 'centers' headed by the reconnect_dsa_head
-; pointer.
-; 
-; To avoid complications in removing commands from the list,
-; I minimize the amount of expensive (at eight operations per
-; addition @ 500-600ns each) pointer operations which must
-; be done in the NCR driver by precomputing them on the 
-; host processor during dsa structure generation.
-;
-; The fixed-up per DSA code knows how to recognize the nexus
-; associated with the corresponding SCSI command, and modifies
-; the source and destination pointers for the MOVE MEMORY 
-; instruction which is executed when reselected_ok is called
-; to remove the command from the list.  Similarly, DSA is 
-; loaded with the address of the next DSA structure and
-; reselected_check_next is called if a failure occurs.
-;
-; Perhaps more concisely, the net effect of the mess is

-; munge_msg
-;
-; PURPOSE : process messages from a target.  msg_in is called when the 
-;	caller hasn't read the first byte of the message.  munge_message
-;	is called when the caller has read the first byte of the message,
-;	and left it in SFBR.  msg_in_restart is called when the caller 
-;	hasn't read the first byte of the message, and wishes RETURN
-;	to transfer control back to the address of the conditional
-;	CALL instruction rather than to the instruction after it.
-;
-;	Various int_* interrupts are generated when the host system
-;	needs to intervene, as is the case with SDTR, WDTR, and
-;	INITIATE RECOVERY messages.
-;
-;	When the host system handles one of these interrupts,
-;	it can respond by reentering at reject_message, 
-;	which rejects the message and returns control to
-;	the caller of msg_in or munge_msg, accept_message
-;	which clears ACK and returns control, or reply_message
-;	which sends the message pointed to by the DSA 
-;	msgout_other table indirect field.
-;
-;	DISCONNECT messages are handled by moving the command
-;	to the reconnect_dsa_queue.
-
-; NOTE: DSA should be valid when we get here - we cannot save both it
-;	and TEMP in this routine.
-
-;
-; INPUTS : DSA - SCSI COMMAND, SFBR - first byte of message (munge_msg
-;	only)
-;
-; CALLS : NO.  The TEMP register isn't backed up to allow nested calls.
-;
-; MODIFIES : SCRATCH, DSA on DISCONNECT
-;
-; EXITS : On receipt of SAVE DATA POINTER, RESTORE POINTERS,
-;	and normal return from message handlers running under
-;	Linux, control is returned to the caller.  Receipt
-;	of DISCONNECT messages pass control to dsa_schedule.

-;
-; PURPOSE : This is essentially the idle routine, where control lands
-;	when there are no new processes to schedule.  wait_reselect
-;	waits for reselection, selection, and new commands.
-;
-;	When a successful reselection occurs, with the aid 
-;	of fixed up code in each DSA, wait_reselect walks the 
-;	reconnect_dsa_queue, asking each dsa if the target ID
-;	and LUN match its.
-;
-;	If a match is found, a call is made back to reselected_ok,
-;	which through the miracles of self modifying code, extracts
-;	the found DSA from the reconnect_dsa_queue and then 
-;	returns control to the DSAs thread of execution.
-;
-; INPUTS : NONE
-;
-; CALLS : OK
-;
-; MODIFIES : DSA,
-;
-; EXITS : On successful reselection, control is returned to the 
-;	DSA which called reselected_ok.  If the WAIT RESELECT
-;	was interrupted by a new commands arrival signaled by 
-;	SIG_P, control is passed to schedule.  If the NCR is 
-;	selected, the host system is interrupted with an 
-;	int_err_selected which is usually responded to by
-;	setting DSP to the target_abort address.

+ * The LM70 communicates with a host processor using a 3-wire variant of
+ * the SPI/Microwire bus interface. This driver specifically supports an
+ * NS LM70 LLP Evaluation Board, interfacing to a PC using its parallel
+ * port to bitbang an SPI-parport bridge.  Accordingly, this is an SPI
+ * master controller driver.  The hwmon/lm70 driver is a "SPI protocol
+ * driver", layered on top of this one and usable without the lm70llp.
+ *
+ * The LM70 is a temperature sensor chip from National Semiconductor; its
+ * datasheet is available at http://www.national.com/pf/LM/LM70.html
+ *
+ * Also see Documentation/spi/spi-lm70llp.  The SPI<->parport code here is
+ * (heavily) based on spi-butterfly by David Brownell.
+ *
+ * The LM70 LLP connects to the PC parallel port in the following manner:
+ *
+ *   Parallel                 LM70 LLP
+ *     Port      Direction   JP2 Header

+ * configfs_depend_item() and configfs_undepend_item()
+ *
+ * WARNING: Do not call these from a configfs callback!
+ *
+ * This describes these functions and their helpers.
+ *
+ * Allow another kernel system to depend on a config_item.  If this
+ * happens, the item cannot go away until the dependant can live without
+ * it.  The idea is to give client modules as simple an interface as
+ * possible.  When a system asks them to depend on an item, they just
+ * call configfs_depend_item().  If the item is live and the client
+ * driver is in good shape, we'll happily do the work for them.
+ *
+ * Why is the locking complex?  Because configfs uses the VFS to handle
+ * all locking, but this function is called outside the normal
+ * VFS->configfs path.  So it must take VFS locks to prevent the
+ * VFS->configfs stuff (configfs_mkdir(), configfs_rmdir(), etc).  This is
+ * why you can't call these functions underneath configfs callbacks.
+ *
+ * Note, btw, that this can be called at *any* time, even when a configfs
+ * subsystem isn't registered, or when configfs is loading or unloading.
+ * Just like configfs_register_subsystem().  So we take the same
+ * precautions.  We pin the filesystem.  We lock each i_mutex _in_order_
+ * on our way down the tree.  If we can find the target item in the
+ * configfs tree, it must be part of the subsystem tree as well, so we
+ * do not need the subsystem semaphore.  Holding the i_mutex chain locks
+ * out mkdir() and rmdir(), who might be racing us.
+ */

+/*
+ * configfs_depend_prep()
+ *
+ * Only subdirectories count here.  Files (CONFIGFS_NOT_PINNED) are
+ * attributes.  This is similar but not the same to configfs_detach_prep().
+ * Note that configfs_detach_prep() expects the parent to be locked when it
+ * is called, but we lock the parent *inside* configfs_depend_prep().  We
+ * do that so we can unlock it if we find nothing.
+ *
+ * Here we do a depth-first search of the dentry hierarchy looking for
+ * our object.  We take i_mutex on each step of the way down.  IT IS
+ * ESSENTIAL THAT i_mutex LOCKING IS ORDERED.  If we come back up a branch,
+ * we'll drop the i_mutex.
+ *
+ * If the target is not found, -ENOENT is bubbled up and we have released
+ * all locks.  If the target was found, the locks will be cleared by
+ * configfs_depend_rollback().
+ *
+ * This adds a requirement that all config_items be unique!
+ *
+ * This is recursive because the locking traversal is tricky.  There isn't
+ * much on the stack, though, so folks that need this function - be careful
+ * about your stack!  Patches will be accepted to make it iterative.

- * find_exported_dentry - helper routine to implement export_operations->decode_fh
- * @sb:		The &super_block identifying the filesystem
- * @obj:	An opaque identifier of the object to be found - passed to
- *		get_inode
- * @parent:	An optional opqaue identifier of the parent of the object.
- * @acceptable:	A function used to test possible &dentries to see if they are
- *		acceptable
- * @context:	A parameter to @acceptable so that it knows on what basis to
- *		judge.
- *
- * find_exported_dentry is the central helper routine to enable file systems
- * to provide the decode_fh() export_operation.  It's main task is to take
- * an &inode, find or create an appropriate &dentry structure, and possibly
- * splice this into the dcache in the correct place.
- *
- * The decode_fh() operation provided by the filesystem should call
- * find_exported_dentry() with the same parameters that it received except
- * that instead of the file handle fragment, pointers to opaque identifiers
- * for the object and optionally its parent are passed.  The default decode_fh
- * routine passes one pointer to the start of the filehandle fragment, and
- * one 8 bytes into the fragment.  It is expected that most filesystems will
- * take this approach, though the offset to the parent identifier may well be
- * different.
- *
- * find_exported_dentry() will call get_dentry to get an dentry pointer from
- * the file system.  If any &dentry in the d_alias list is acceptable, it will
- * be returned.  Otherwise find_exported_dentry() will attempt to splice a new
- * &dentry into the dcache using get_name() and get_parent() to find the
- * appropriate place.

+ * find_exported_dentry - helper routine to implement export_operations->decode_fh
+ * @sb:		The &super_block identifying the filesystem
+ * @obj:	An opaque identifier of the object to be found - passed to
+ *		get_inode
+ * @parent:	An optional opqaue identifier of the parent of the object.
+ * @acceptable:	A function used to test possible &dentries to see if they are
+ *		acceptable
+ * @context:	A parameter to @acceptable so that it knows on what basis to
+ *		judge.
+ *
+ * find_exported_dentry is the central helper routine to enable file systems
+ * to provide the decode_fh() export_operation.  It's main task is to take
+ * an &inode, find or create an appropriate &dentry structure, and possibly
+ * splice this into the dcache in the correct place.
+ *
+ * The decode_fh() operation provided by the filesystem should call
+ * find_exported_dentry() with the same parameters that it received except
+ * that instead of the file handle fragment, pointers to opaque identifiers
+ * for the object and optionally its parent are passed.  The default decode_fh
+ * routine passes one pointer to the start of the filehandle fragment, and
+ * one 8 bytes into the fragment.  It is expected that most filesystems will
+ * take this approach, though the offset to the parent identifier may well be
+ * different.
+ *
+ * find_exported_dentry() will call get_dentry to get an dentry pointer from
+ * the file system.  If any &dentry in the d_alias list is acceptable, it will
+ * be returned.  Otherwise find_exported_dentry() will attempt to splice a new
+ * &dentry into the dcache using get_name() and get_parent() to find the
+ * appropriate place.

+ * Allocation group filestream associations are tracked with per-ag atomic
+ * counters.  These counters allow _xfs_filestream_pick_ag() to tell whether a
+ * particular AG already has active filestreams associated with it. The mount
+ * point's m_peraglock is used to protect these counters from per-ag array
+ * re-allocation during a growfs operation.  When xfs_growfs_data_private() is
+ * about to reallocate the array, it calls xfs_filestream_flush() with the
+ * m_peraglock held in write mode.
+ *
+ * Since xfs_mru_cache_flush() guarantees that all the free functions for all
+ * the cache elements have finished executing before it returns, it's safe for
+ * the free functions to use the atomic counters without m_peraglock protection.
+ * This allows the implementation of xfs_fstrm_free_func() to be agnostic about
+ * whether it was called with the m_peraglock held in read mode, write mode or
+ * not held at all.  The race condition this addresses is the following:
+ *
+ *  - The work queue scheduler fires and pulls a filestream directory cache
+ *    element off the LRU end of the cache for deletion, then gets pre-empted.
+ *  - A growfs operation grabs the m_peraglock in write mode, flushes all the
+ *    remaining items from the cache and reallocates the mount point's per-ag
+ *    array, resetting all the counters to zero.
+ *  - The work queue thread resumes and calls the free function for the element
+ *    it started cleaning up earlier.  In the process it decrements the
+ *    filestreams counter for an AG that now has no references.
+ *
+ * With a shrinkfs feature, the above scenario could panic the system.
+ *
+ * All other uses of the following macros should be protected by either the
+ * m_peraglock held in read mode, or the cache's internal locking exposed by the
+ * interval between a call to xfs_mru_cache_lookup() and a call to
+ * xfs_mru_cache_done().  In addition, the m_peraglock must be held in read mode
+ * when new elements are added to the cache.
+ *
+ * Combined, these locking rules ensure that no associations will ever exist in
+ * the cache that reference per-ag array elements that have since been
+ * reallocated.

+/*
+ * The MRU Cache data structure consists of a data store, an array of lists and
+ * a lock to protect its internal state.  At initialisation time, the client
+ * supplies an element lifetime in milliseconds and a group count, as well as a
+ * function pointer to call when deleting elements.  A data structure for
+ * queueing up work in the form of timed callbacks is also included.
+ *
+ * The group count controls how many lists are created, and thereby how finely
+ * the elements are grouped in time.  When reaping occurs, all the elements in
+ * all the lists whose time has expired are deleted.
+ *
+ * To give an example of how this works in practice, consider a client that
+ * initialises an MRU Cache with a lifetime of ten seconds and a group count of
+ * five.  Five internal lists will be created, each representing a two second
+ * period in time.  When the first element is added, time zero for the data
+ * structure is initialised to the current time.
+ *
+ * All the elements added in the first two seconds are appended to the first
+ * list.  Elements added in the third second go into the second list, and so on.
+ * If an element is accessed at any point, it is removed from its list and
+ * inserted at the head of the current most-recently-used list.
+ *
+ * The reaper function will have nothing to do until at least twelve seconds
+ * have elapsed since the first element was added.  The reason for this is that
+ * if it were called at t=11s, there could be elements in the first list that
+ * have only been inactive for nine seconds, so it still does nothing.  If it is
+ * called anywhere between t=12 and t=14 seconds, it will delete all the
+ * elements that remain in the first list.  It's therefore possible for elements
+ * to remain in the data store even after they've been inactive for up to
+ * (t + t/g) seconds, where t is the inactive element lifetime and g is the
+ * number of groups.
+ *
+ * The above example assumes that the reaper function gets called at least once
+ * every (t/g) seconds.  If it is called less frequently, unused elements will
+ * accumulate in the reap list until the reaper function is eventually called.
+ * The current implementation uses work queue callbacks to carefully time the
+ * reaper function calls, so this should happen rarely, if at all.
+ *
+ * From a design perspective, the primary reason for the choice of a list array
+ * representing discrete time intervals is that it's only practical to reap
+ * expired elements in groups of some appreciable size.  This automatically
+ * introduces a granularity to element lifetimes, so there's no point storing an
+ * individual timeout with each element that specifies a more precise reap time.
+ * The bonus is a saving of sizeof(long) bytes of memory per element stored.
+ *
+ * The elements could have been stored in just one list, but an array of
+ * counters or pointers would need to be maintained to allow them to be divided
+ * up into discrete time groups.  More critically, the process of touching or
+ * removing an element would involve walking large portions of the entire list,
+ * which would have a detrimental effect on performance.  The additional memory
+ * requirement for the array of list heads is minimal.
+ *
+ * When an element is touched or deleted, it needs to be removed from its
+ * current list.  Doubly linked lists are used to make the list maintenance
+ * portion of these operations O(1).  Since reaper timing can be imprecise,
+ * inserts and lookups can occur when there are no free lists available.  When
+ * this happens, all the elements on the LRU list need to be migrated to the end
+ * of the reap list.  To keep the list maintenance portion of these operations
+ * O(1) also, list tails need to be accessible without walking the entire list.
+ * This is the reason why doubly linked list heads are used.
+ */
+
+/*
+ * An MRU Cache is a dynamic data structure that stores its elements in a way
+ * that allows efficient lookups, but also groups them into discrete time
+ * intervals based on insertion time.  This allows elements to be efficiently
+ * and automatically reaped after a fixed period of inactivity.
+ *
+ * When a client data pointer is stored in the MRU Cache it needs to be added to
+ * both the data store and to one of the lists.  It must also be possible to
+ * access each of these entries via the other, i.e. to:
+ *
+ *    a) Walk a list, removing the corresponding data store entry for each item.
+ *    b) Look up a data store entry, then access its list entry directly.
+ *
+ * To achieve both of these goals, each entry must contain both a list entry and
+ * a key, in addition to the user's data pointer.  Note that it's not a good
+ * idea to have the client embed one of these structures at the top of their own
+ * data structure, because inserting the same item more than once would most
+ * likely result in a loop in one of the lists.  That's a sure-fire recipe for
+ * an infinite loop in the code.

+ * struct export_operations - for nfsd to communicate with file systems
+ * @decode_fh:      decode a file handle fragment and return a &struct dentry
+ * @encode_fh:      encode a file handle fragment from a dentry
+ * @get_name:       find the name for a given inode in a given directory
+ * @get_parent:     find the parent of a given directory

+ * @find_exported_dentry:
+ *	set by the exporting module to a standard helper function.
+ *
+ * Description:
+ *    The export_operations structure provides a means for nfsd to communicate
+ *    with a particular exported file system  - particularly enabling nfsd and
+ *    the filesystem to co-operate when dealing with file handles.
+ *
+ *    export_operations contains two basic operation for dealing with file
+ *    handles, decode_fh() and encode_fh(), and allows for some other
+ *    operations to be defined which standard helper routines use to get
+ *    specific information from the filesystem.
+ *
+ *    nfsd encodes information use to determine which filesystem a filehandle
+ *    applies to in the initial part of the file handle.  The remainder, termed
+ *    a file handle fragment, is controlled completely by the filesystem.  The
+ *    standard helper routines assume that this fragment will contain one or
+ *    two sub-fragments, one which identifies the file, and one which may be
+ *    used to identify the (a) directory containing the file.
+ *
+ *    In some situations, nfsd needs to get a dentry which is connected into a
+ *    specific part of the file tree.  To allow for this, it passes the
+ *    function acceptable() together with a @context which can be used to see
+ *    if the dentry is acceptable.  As there can be multiple dentrys for a
+ *    given file, the filesystem should check each one for acceptability before
+ *    looking for the next.  As soon as an acceptable one is found, it should
+ *    be returned.
+ *
+ * decode_fh:
+ *    @decode_fh is given a &struct super_block (@sb), a file handle fragment
+ *    (@fh, @fh_len) and an acceptability testing function (@acceptable,
+ *    @context).  It should return a &struct dentry which refers to the same
+ *    file that the file handle fragment refers to,  and which passes the
+ *    acceptability test.  If it cannot, it should return a %NULL pointer if
+ *    the file was found but no acceptable &dentries were available, or a
+ *    %ERR_PTR error code indicating why it couldn't be found (e.g. %ENOENT or
+ *    %ENOMEM).
+ *
+ * encode_fh:
+ *    @encode_fh should store in the file handle fragment @fh (using at most
+ *    @max_len bytes) information that can be used by @decode_fh to recover the
+ *    file refered to by the &struct dentry @de.  If the @connectable flag is
+ *    set, the encode_fh() should store sufficient information so that a good
+ *    attempt can be made to find not only the file but also it's place in the
+ *    filesystem.   This typically means storing a reference to de->d_parent in
+ *    the filehandle fragment.  encode_fh() should return the number of bytes
+ *    stored or a negative error code such as %-ENOSPC
+ *
+ * get_name:
+ *    @get_name should find a name for the given @child in the given @parent
+ *    directory.  The name should be stored in the @name (with the
+ *    understanding that it is already pointing to a a %NAME_MAX+1 sized
+ *    buffer.   get_name() should return %0 on success, a negative error code
+ *    or error.  @get_name will be called without @parent->i_mutex held.
+ *
+ * get_parent:
+ *    @get_parent should find the parent directory for the given @child which
+ *    is also a directory.  In the event that it cannot be found, or storage
+ *    space cannot be allocated, a %ERR_PTR should be returned.
+ *
+ * get_dentry:
+ *    Given a &super_block (@sb) and a pointer to a file-system specific inode
+ *    identifier, possibly an inode number, (@inump) get_dentry() should find
+ *    the identified inode and return a dentry for that inode.  Any suitable
+ *    dentry can be returned including, if necessary, a new dentry created with
+ *    d_alloc_root.  The caller can then find any other extant dentrys by
+ *    following the d_alias links.  If a new dentry was created using
+ *    d_alloc_root, DCACHE_NFSD_DISCONNECTED should be set, and the dentry
+ *    should be d_rehash()ed.
+ *
+ *    If the inode cannot be found, either a %NULL pointer or an %ERR_PTR code
+ *    can be returned.  The @inump will be whatever was passed to
+ *    nfsd_find_fh_dentry() in either the @obj or @parent parameters.
+ *
+ * Locking rules:
+ *    get_parent is called with child->d_inode->i_mutex down
+ *    get_name is not (which is possibly inconsistent)

+ * Stripe operations are performed outside the stripe lock,
+ * the stripe operations are:
+ * -copying data between the stripe cache and user application buffers
+ * -computing blocks to save a disk access, or to recover a missing block
+ * -updating the parity on a write operation (reconstruct write and
+ *  read-modify-write)
+ * -checking parity correctness
+ * -running i/o to disk
+ * These operations are carried out by raid5_run_ops which uses the async_tx
+ * api to (optionally) offload operations to dedicated hardware engines.
+ * When requesting an operation handle_stripe sets the pending bit for the
+ * operation and increments the count.  raid5_run_ops is then run whenever
+ * the count is non-zero.
+ * There are some critical dependencies between the operations that prevent some
+ * from being requested while another is in flight.
+ * 1/ Parity check operations destroy the in cache version of the parity block,
+ *    so we prevent parity dependent operations like writes and compute_blocks
+ *    from starting while a check is in progress.  Some dma engines can perform
+ *    the check without damaging the parity block, in these cases the parity
+ *    block is re-marked up to date (assuming the check was successful) and is
+ *    not re-read from disk.
+ * 2/ When a write operation is requested we immediately lock the affected
+ *    blocks, and mark them as not up to date.  This causes new read requests
+ *    to be held off, as well as parity checks and compute block operations.
+ * 3/ Once a compute block operation has been requested handle_stripe treats
+ *    that block as if it is up to date.  raid5_run_ops guaruntees that any

  * Matt Mackall <mpm@selenic.com> 12/30/03
  *
+ * NUMA support by Paul Mundt, 2007.
+ *
  * How SLOB works:
  *
  * The core of SLOB is a traditional K&R style heap allocator, with
  * support for returning aligned objects. The granularity of this
- * allocator is 8 bytes on x86, though it's perhaps possible to reduce
- * this to 4 if it's deemed worth the effort. The slob heap is a
- * singly-linked list of pages from __get_free_page, grown on demand
- * and allocation from the heap is currently first-fit.
+ * allocator is as little as 2 bytes, however typically most architectures
+ * will require 4 bytes on 32-bit and 8 bytes on 64-bit.
+ *
+ * The slob heap is a linked list of pages from alloc_pages(), and
+ * within each page, there is a singly-linked list of free blocks (slob_t).
+ * The heap is grown on demand and allocation from the heap is currently
+ * first-fit.
  *
  * Above this is an implementation of kmalloc/kfree. Blocks returned
- * from kmalloc are 8-byte aligned and prepended with a 8-byte header.
+ * from kmalloc are prepended with a 4-byte header with the kmalloc size.
  * If kmalloc is asked for objects of PAGE_SIZE or larger, it calls
- * __get_free_pages directly so that it can return page-aligned blocks
- * and keeps a linked list of such pages and their orders. These
- * objects are detected in kfree() by their page alignment.
+ * alloc_pages() directly, allocating compound pages so the page order
+ * does not have to be separately tracked, and also stores the exact
+ * allocation size in page->private so that it can be used to accurately
+ * provide ksize(). These objects are detected in kfree() because slob_page()
+ * is false for them.
  *
  * SLAB is emulated on top of SLOB by simply calling constructors and
- * destructors for every SLAB allocation. Objects are returned with
- * the 8-byte alignment unless the SLAB_HWCACHE_ALIGN flag is
- * set, in which case the low-level allocator will fragment blocks to
- * create the proper alignment. Again, objects of page-size or greater
- * are allocated by calling __get_free_pages. As SLAB objects know
- * their size, no separate size bookkeeping is necessary and there is
- * essentially no allocation space overhead.
+ * destructors for every SLAB allocation. Objects are returned with the
+ * 4-byte alignment unless the SLAB_HWCACHE_ALIGN flag is set, in which
+ * case the low-level allocator will fragment blocks to create the proper
+ * alignment. Again, objects of page-size or greater are allocated by
+ * calling alloc_pages(). As SLAB objects know their size, no separate
+ * size bookkeeping is necessary and there is essentially no allocation
+ * space overhead, and compound pages aren't needed for multi-page
+ * allocations.
+ *
+ * NUMA support in SLOB is fairly simplistic, pushing most of the real
+ * logic down to the page allocator, and simply doing the node accounting
+ * on the upper levels. In the event that a node id is explicitly
+ * provided, alloc_pages_node() with the specified node id is used
+ * instead. The common case (or when the node id isn't explicitly provided)
+ * will default to the current node, as per numa_node_id().
+ *
+ * Node aware pages are still inserted in to the global freelist, and
+ * these are scanned for by matching against the node id encoded in the
+ * page flags. As a result, block allocations that can be satisfied from
+ * the freelist will only be done so on pages residing on the same node,
+ * in order to prevent random node placement.

+ *
+ * Returns: 0 or a negative error code if there is a problem.

+ * This function initializes an opaque iterator struct which can then

+ * argument which is present in the header.  It knows about extended
+ * present headers and handles them.
+ *
+ * How to use:
+ * call __ieee80211_radiotap_iterator_init() to init a semi-opaque iterator
+ * struct ieee80211_radiotap_iterator (no need to init the struct beforehand)
+ * checking for a good 0 return code.  Then loop calling
+ * __ieee80211_radiotap_iterator_next()... it returns either 0,
+ * -ENOENT if there are no more args to parse, or -EINVAL if there is a problem.
+ * The iterator's @this_arg member points to the start of the argument
+ * associated with the current argument index that is present, which can be
+ * found in the iterator's @this_arg_index member.  This arg index corresponds
+ * to the IEEE80211_RADIOTAP_... defines.
+ *
+ * Radiotap header length:
+ * You can find the CPU-endian total radiotap header length in
+ * iterator->max_length after executing ieee80211_radiotap_iterator_init()
+ * successfully.
+ *
+ * Alignment Gotcha:
+ * You must take care when dereferencing iterator.this_arg
+ * for multibyte types... the pointer is not aligned.  Use
+ * get_unaligned((type *)iterator.this_arg) to dereference
+ * iterator.this_arg for type "type" safely on all arches.
+ *
+ * Example code:

-/*
- * Audio Command Interface (ACI) driver (sound/aci.c)
- *
- * ACI is a protocol used to communicate with the microcontroller on
- * some sound cards produced by miro, e.g. the miroSOUND PCM12 and
- * PCM20. The ACI has been developed for miro by Norberto Pellicci
- * <pellicci@home.com>. Special thanks to both him and miro for
- * providing the ACI specification.
- *
- * The main function of the ACI is to control the mixer and to get a
- * product identification. On the PCM20, ACI also controls the radio
- * tuner on this card, this is supported in the Video for Linux 
- * miropcm20 driver.
- * -
- * This is a fullfeatured implementation. Unsupported features
- * are bugs... (:
- *
- * It is not longer necessary to load the mad16 module first. The
- * user is currently responsible to set the mad16 mixer correctly.
- *
- * To toggle the solo mode for full duplex operation just use the OSS
- * record switch for the pcm ('wave') controller.           Robert
- * -
- *
- * Revision history:
- *
- *   1995-11-10  Markus Kuhn <mskuhn@cip.informatik.uni-erlangen.de>
- *        First version written.
- *   1995-12-31  Markus Kuhn
- *        Second revision, general code cleanup.
- *   1996-05-16	 Hannu Savolainen
- *	  Integrated with other parts of the driver.
- *   1996-05-28  Markus Kuhn
- *        Initialize CS4231A mixer, make ACI first mixer,
- *        use new private mixer API for solo mode.
- *   1998-08-18  Ruurd Reitsma <R.A.Reitsma@wbmt.tudelft.nl>
- *	  Small modification to export ACI functions and 
- *	  complete modularisation.
- *   2000-06-20  Robert Siemer <Robert.Siemer@gmx.de>
- *        Don't initialize the CS4231A mixer anymore, so the code is
- *        working again, and other small changes to fit in todays
- *        kernels.
- *   2000-08-26  Robert Siemer
- *        Clean up and rewrite for 2.4.x. Maybe it's SMP safe now... (:
- *        ioctl bugfix, and integration of solo-mode into OSS-API,
- *        added (OSS-limited) equalizer support, return value bugfix,
- *        changed param aci_reset to reset, new params: ide, wss.
- *   2001-04-20  Robert Siemer
- *        even more cleanups...
- *   2001-10-08  Arnaldo Carvalho de Melo <acme@conectiva.com.br>
- *   	  Get rid of check_region, .bss optimizations, use set_current_state

- * Based on the CS4232/AD1848 driver Copyright (C) by Hannu Savolainen 1993-1996
- *
- *
- * version: 1.5
- * status: beta
- * date: 2003/07/15
- *
- * Changes:
- *	Oleg Drokin: Some cleanup of load/unload functions.	1998/11/24
- *	
- *	Thorsten Knabe: attach and unload rewritten, 
- *	some argument checks added				1998/11/30
- *
- *	Thorsten Knabe: Buggy isa bridge workaround added	1999/01/16
- *	
- *	David Moews/Thorsten Knabe: Introduced options 
- *	parameter. Added slightly modified patch from 
- *	David Moews to disable dsp audio sources by setting 
- *	bit 0 of options parameter. This seems to be
- *	required by some Aztech/Newcom SC-16 cards.		1999/04/18
- *
- *	Christoph Hellwig: Adapted to module_init/module_exit.	2000/03/03
- *
- *	Christoph Hellwig: Added isapnp support			2000/03/15
- *
- *	Arnaldo Carvalho de Melo: get rid of check_region	2001/10/07
- *      
- *      Thorsten Knabe: Compiling with CONFIG_PNP enabled
- *	works again. It is now possible to use more than one 
- *	AD1816 sound card. Sample rate now may be changed during
- *	playback/capture. printk() uses log levels everywhere.
- *	SMP fixes. DMA handling fixes.
- *	Other minor code cleanup.				2003/07/15

-<jsm> tausq: Anyway, to set up sample rates for D to A, you just use the sample rate on the codec. For A to D, you need to set the codec always to 48K (using the split sample rate feature on the codec) and then set the resampler on the AD1889 to the sample rate you want.
-<jsm> Also, when changing the sample rate on the codec you need to power it down and re power it up for the change to take effect!

- *
- *	Changes:
- *	20000909-nf	Changed cs_read, cs_write and drain_dac
- *	20001025-tw	Separate Playback/Capture structs and buffers.
- *			Added Scatter/Gather support for Playback.
- *			Added Capture.
- *	20001027-nf	Port to kernel 2.4.0-test9, some clean-ups
- *			Start of powermanagement support (CS46XX_PM).
- *	20001128-tw	Add module parm for default buffer order.
- *			added DMA_GFP flag to kmalloc dma buffer allocs.
- *			backfill silence to eliminate stuttering on
- *			underruns.
- *	20001201-tw	add resyncing of swptr on underruns.
- *	20001205-tw-nf	fixed GETOSPACE ioctl() after open()
- *	20010113-tw	patch from Hans Grobler general cleanup.
- *	20010117-tw	2.4.0 pci cleanup, wrapper code for 2.2.16-2.4.0
- *	20010118-tw	basic PM support for 2.2.16+ and 2.4.0/2.4.2.
- *	20010228-dh	patch from David Huggins - cs_update_ptr recursion.
- *	20010409-tw	add hercules game theatre XP amp code.
- *	20010420-tw	cleanup powerdown/up code.
- *	20010521-tw	eliminate pops, and fixes for powerdown.
- *	20010525-tw	added fixes for thinkpads with powerdown logic.
- *	20010723-sh     patch from Horms (Simon Horman) -
- *	                SOUND_PCM_READ_BITS returns bits as set in driver
- *	                rather than a logical or of the possible values.
- *	                Various ioctls handle the case where the device
- *	                is open for reading or writing but not both better.
- *
- *	Status:
- *	Playback/Capture supported from 8k-48k.
- *	16Bit Signed LE & 8Bit Unsigned, with Mono or Stereo supported.
- *
- *	APM/PM - 2.2.x APM is enabled and functioning fine. APM can also
- *	be enabled for 2.4.x by modifying the CS46XX_ACPI_SUPPORT macro
- *	definition.
- *
- *      Hercules Game Theatre XP - the EGPIO2 pin controls the external Amp,
- *	so, use the drain/polarity to enable.  
- *	hercules_egpio_disable set to 1, will force a 0 to EGPIODR.
- *
- *	VTB Santa Cruz - the GPIO7/GPIO8 on the Secondary Codec control
- *	the external amplifier for the "back" speakers, since we do not
- *	support the secondary codec then this external amp is also not
- *	turned on.

-  Passthrough can be done in two methods:
-
-  Method 1 : tram
-     In original emu10k1, we couldn't bypass the sample rate converters. Even at 48kHz
-     (the internal sample rate of the emu10k1) the samples would get messed up.
-     To over come this, samples are copied into the tram and a special dsp patch copies
-     the samples out and generates interrupts when a block has finnished playing.
-
-  Method 2 : Interpolator bypass
-
-     Creative fixed the sample rate convert problem in emu10k1 rev 7 and higher
-     (including the emu10k2 (audigy)). This allows us to use the regular, and much simpler
-     playback method. 
-
-
-  In both methods, dsp code is used to mux audio and passthrough. This ensures that the spdif
-  doesn't receive audio and pasthrough data at the same time. The spdif flag SPCS_NOTAUDIODATA
-  is set to tell

- * NOTE: All traces of the name OPL3-SAx have now (December 2000) been
- *       removed from the driver code, as an email exchange with Yamaha
- *       provided the information that the YMF-719 is indeed just a
- *       re-badged 715.
- *
- * Copyright 1998-2001 Scott Murray <scott@spiteful.org>
- *
- * Originally based on the CS4232 driver (in cs4232.c) by Hannu Savolainen
- * and others.  Now incorporates code/ideas from pss.c, also by Hannu

- * Change History
- * --------------
- * Scott Murray            Original driver (Jun 14, 1998)
- * Paul J.Y. Lahaie        Changed probing / attach code order
- * Scott Murray            Added mixer support (Dec 03, 1998)
- * Scott Murray            Changed detection code to be more forgiving,
- *                         added force option as last resort,
- *                         fixed ioctl return values. (Dec 30, 1998)
- * Scott Murray            Simpler detection code should work all the time now
- *                         (with thanks to Ben Hutchings for the heuristic),
- *                         removed now unnecessary force option. (Jan 5, 1999)
- * Christoph Hellwig	   Adapted to module_init/module_exit (Mar 4, 2000)
- * Scott Murray            Reworked SA2 versus SA3 mixer code, updated chipset
- *                         version detection code (again!). (Dec 5, 2000)
- * Scott Murray            Adjusted master volume mixer scaling. (Dec 6, 2000)
- * Scott Murray            Based on a patch by Joel Yliluoma (aka Bisqwit),
- *                         integrated wide mixer and adjusted mic, bass, treble
- *                         scaling. (Dec 6, 2000)
- * Scott Murray            Based on a patch by Peter Englmaier, integrated
- *                         ymode and loopback options. (Dec 6, 2000)
- * Scott Murray            Inspired by a patch by Peter Englmaier, and based on
- *                         what ALSA does, added initialization code for the
- *                         default DMA and IRQ settings. (Dec 6, 2000)
- * Scott Murray            Added some more checks to the card detection code,
- *                         based on what ALSA does. (Dec 12, 2000)
- * Scott Murray            Inspired by similar patches from John Fremlin,
- *                         Jim Radford, Mike Rolig, and Ingmar Steen, added 2.4
- *                         ISA PnP API support, mainly based on bits from
- *                         sb_card.c and awe_wave.c. (Dec 12, 2000)
- * Scott Murray            Some small cleanups to the init code output.
- *                         (Jan 7, 2001)
- * Zwane Mwaikambo	   Added PM support. (Dec 4 2001)
- *
- * Adam Belay              Converted driver to new PnP Layer (Oct 12, 2002)
- * Zwane Mwaikambo	   Code, data structure cleanups. (Feb 15 2002)
- * Zwane Mwaikambo	   Free resources during auxiliary device probe
- * 			   failures (Apr 29 2002)
- *
