- A. Linux Kernels Supported by this Driver
-
- This driver has been tested in the following Linux kernels: v2.2.18
- v2.4.0. The driver is supported on v2.2 and v2.4 kernels and on x86,
- alpha, and PowerPC platforms.
-
- B. Adapters Supported by this Driver
-
- AdvanSys (Advanced System Products, Inc.) manufactures the following
- RISC-based, Bus-Mastering, Fast (10 Mhz) and Ultra (20 Mhz) Narrow
- (8-bit transfer) SCSI Host Adapters for the ISA, EISA, VL, and PCI
- buses and RISC-based, Bus-Mastering, Ultra (20 Mhz) Wide (16-bit
- transfer) SCSI Host Adapters for the PCI bus.
-
- The CDB counts below indicate the number of SCSI CDB (Command
- Descriptor Block) requests that can be stored in the RISC chip
- cache and board LRAM. A CDB is a single SCSI command. The driver
- detect routine will display the number of CDBs available for each
- adapter detected. The number of CDBs used by the driver can be
- lowered in the BIOS by changing the 'Host Queue Size' adapter setting.

- C. Linux source files modified by AdvanSys Driver
-
- This section for historical purposes documents the changes
- originally made to the Linux kernel source to add the advansys
- driver. As Linux has changed some of these files have also
- been modified.
-
- 1. linux/arch/i386/config.in:
-
- bool 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS y
-
- 2. linux/drivers/scsi/hosts.c:
-
- #ifdef CONFIG_SCSI_ADVANSYS
- #include "advansys.h"
- #endif
-
- and after "static struct scsi_host_template builtin_scsi_hosts[] =":
-
- #ifdef CONFIG_SCSI_ADVANSYS
- ADVANSYS,
- #endif
-
- 3. linux/drivers/scsi/Makefile:
-
- ifdef CONFIG_SCSI_ADVANSYS
- SCSI_SRCS := $(SCSI_SRCS) advansys.c
- SCSI_OBJS := $(SCSI_OBJS) advansys.o
- else
- SCSI_MODULE_OBJS := $(SCSI_MODULE_OBJS) advansys.o
- endif
-
- 4. linux/init/main.c:
-
- extern void advansys_setup(char *str, int *ints);
-
- and add the following lines to the bootsetups[] array.
-
- #ifdef CONFIG_SCSI_ADVANSYS
- { "advansys=", advansys_setup },
- #endif
-
- D. Source Comments
-
- 1. Use tab stops set to 4 for the source files. For vi use 'se tabstops=4'.
-
- 2. This driver should be maintained in multiple files. But to make
- it easier to include with Linux and to follow Linux conventions,
- the whole driver is maintained in the source files advansys.h and
- advansys.c. In this file logical sections of the driver begin with
- a comment that contains '---'. The following are the logical sections
- of the driver below.

- or that contains a problem that needs to be addressed.
-
- 4. I have stripped comments from and reformatted the source for the
- Asc Library and Adv Library to reduce the size of this file. This
- source can be found under the following headings. The Asc Library
- is used to support Narrow Boards. The Adv Library is used to
- support Wide Boards.

-
- E. Driver Compile Time Options and Debugging
-
- In this source file the following constants can be defined. They are
- defined in the source below. Both of these options are enabled by
- default.
-
- 1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
-
- Enabling this option adds assertion logic statements to the
- driver. If an assertion fails a message will be displayed to
- the console, but the system will continue to operate. Any
- assertions encountered should be reported to the person
- responsible for the driver. Assertion statements may proactively
- detect problems with the driver and facilitate fixing these
- problems. Enabling assertions will add a small overhead to the
- execution of the driver.
-
- 2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
-
- Enabling this option adds tracing functions to the driver and
- the ability to set a driver tracing level at boot time. This
- option will also export symbols not required outside the driver to
- the kernel name space. This option is very useful for debugging
- the driver, but it will add to the size of the driver execution
- image and add overhead to the execution of the driver.
-
- The amount of debugging output can be controlled with the global
- variable 'asc_dbglvl'. The higher the number the more output. By
- default the debug level is 0.
-
- If the driver is loaded at boot time and the LILO Driver Option
- is included in the system, the debug level can be changed by
- specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
- first three hex digits of the pseudo I/O Port must be set to
- 'deb' and the fourth hex digit specifies the debug level: 0 - F.
- The following command line will look for an adapter at 0x330
- and set the debug level to 2.
-
- linux advansys=0x330,0,0,0,0xdeb2
-
- If the driver is built as a loadable module this variable can be
- defined when the driver is loaded. The following insmod command
- will set the debug level to one.
-
- insmod advansys.o asc_dbglvl=1
-
- Debugging Message Levels:
- 0: Errors Only
- 1: High-Level Tracing
- 2-N: Verbose Tracing
-
- To enable debug output to console, please make sure that:
-
- a. System and kernel logging is enabled (syslogd, klogd running).
- b. Kernel messages are routed to console output. Check
- /etc/syslog.conf for an entry similar to this:
-
- kern.* /dev/console
-
- c. klogd is started with the appropriate -c parameter
- (e.g. klogd -c 8)
-
- This will cause printk() messages to be be displayed on the
- current console. Refer to the klogd(8) and syslogd(8) man pages
- for details.
-
- Alternatively you can enable printk() to console with this
- program. However, this is not the 'official' way to do this.
- Debug output is logged in /var/log/messages.
-
- main()
- {
- syscall(103, 7, 0, 0);
- }
-
- Increasing LOG_BUF_LEN in kernel/printk.c to something like
- 40960 allows more debug messages to be buffered in the kernel
- and written to the console or log file.
-
- 3. ADVANSYS_STATS - Enable statistics (Def: Enabled >= v1.3.0)
-
- Enabling this option adds statistics collection and display
- through /proc to the driver. The information is useful for
- monitoring driver and device performance. It will add to the
- size of the driver execution image and add minor overhead to
- the execution of the driver.
-
- Statistics are maintained on a per adapter basis. Driver entry
- point call counts and transfer size counts are maintained.
- Statistics are only available for kernels greater than or equal
- to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
-
- AdvanSys SCSI adapter files have the following path name format:
-
- /proc/scsi/advansys/[0-(ASC_NUM_BOARD_SUPPORTED-1)]
-
- This information can be displayed with cat. For example:
-
- cat /proc/scsi/advansys/0
-
- When ADVANSYS_STATS is not defined the AdvanSys /proc files only
- contain adapter and device configuration information.
-
- F. Driver LILO Option
-
- If init/main.c is modified as described in the 'Directions for Adding
- the AdvanSys Driver to Linux' section (B.4.) above, the driver will
- recognize the 'advansys' LILO command line and /etc/lilo.conf option.
- This option can be used to either disable I/O port scanning or to limit
- scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
- PCI boards will still be searched for and detected. This option only
- affects searching for ISA and VL boards.
-
- Examples:
- 1. Eliminate I/O port scanning:
- boot: linux advansys=
- or
- boot: linux advansys=0x0
- 2. Limit I/O port scanning to one I/O port:
- boot: linux advansys=0x110
- 3. Limit I/O port scanning to four I/O ports:
- boot: linux advansys=0x110,0x210,0x230,0x330
-
- For a loadable module the same effect can be achieved by setting
- the 'asc_iopflag' variable and 'asc_ioport' array when loading
- the driver, e.g.
-
- insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
-
- If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
- I/O Port may be added to specify the driver debug level. Refer to
- the 'Driver Compile Time Options and Debugging' section above for
- more information.
-
- G. Tests to run before releasing new driver
-
- 1. In the supported kernels verify there are no warning or compile
- errors when the kernel is built as both a driver and as a module
- and with the following options:
-
- ADVANSYS_DEBUG - enabled and disabled
- CONFIG_SMP - enabled and disabled
- CONFIG_PROC_FS - enabled and disabled
-
- 2. Run tests on an x86, alpha, and PowerPC with at least one narrow
- card and one wide card attached to a hard disk and CD-ROM drive:
- fdisk, mkfs, fsck, bonnie, copy/compare test from the
- CD-ROM to the hard drive.
-
- H. Release History
-
- BETA-1.0 (12/23/95):
- First Release
-
- BETA-1.1 (12/28/95):
- 1. Prevent advansys_detect() from being called twice.
- 2. Add LILO 0xdeb[0-f] option to set 'asc_dbglvl'.
-
- 1.2 (1/12/96):
- 1. Prevent re-entrancy in the interrupt handler which
- resulted in the driver hanging Linux.
- 2. Fix problem that prevented ABP-940 cards from being
- recognized on some PCI motherboards.
- 3. Add support for the ABP-5140 PnP ISA card.
- 4. Fix check condition return status.
- 5. Add conditionally compiled code for Linux v1.3.X.
-
- 1.3 (2/23/96):
- 1. Fix problem in advansys_biosparam() that resulted in the
- wrong drive geometry being returned for drives > 1GB with
- extended translation enabled.
- 2. Add additional tracing during device initialization.
- 3. Change code that only applies to ISA PnP adapter.
- 4. Eliminate 'make dep' warning.
- 5. Try to fix problem with handling resets by increasing their
- timeout value.
-
- 1.4 (5/8/96):
- 1. Change definitions to eliminate conflicts with other subsystems.
- 2. Add versioning code for the shared interrupt changes.
- 3. Eliminate problem in asc_rmqueue() with iterating after removing
- a request.
- 4. Remove reset request loop problem from the "Known Problems or
- Issues" section. This problem was isolated and fixed in the
- mid-level SCSI driver.
-
- 1.5 (8/8/96):
- 1. Add support for ABP-940U (PCI Ultra) adapter.
- 2. Add support for IRQ sharing by setting the IRQF_SHARED flag for
- request_irq and supplying a dev_id pointer to both request_irq()
- and free_irq().
- 3. In AscSearchIOPortAddr11() restore a call to check_region() which
- should be used before I/O port probing.
- 4. Fix bug in asc_prt_hex() which resulted in the displaying
- the wrong data.
- 5. Incorporate miscellaneous Asc Library bug fixes and new microcode.
- 6. Change driver versioning to be specific to each Linux sub-level.
- 7. Change statistics gathering to be per adapter instead of global
- to the driver.
- 8. Add more information and statistics to the adapter /proc file:
- /proc/scsi/advansys[0...].
- 9. Remove 'cmd_per_lun' from the "Known Problems or Issues" list.
- This problem has been addressed with the SCSI mid-level changes
- made in v1.3.89. The advansys_select_queue_depths() function
- was added for the v1.3.89 changes.
-
- 1.6 (9/10/96):
- 1. Incorporate miscellaneous Asc Library bug fixes and new microcode.
-
- 1.7 (9/25/96):
- 1. Enable clustering and optimize the setting of the maximum number
- of scatter gather elements for any particular board. Clustering
- increases CPU utilization, but results in a relatively larger
- increase in I/O throughput.
- 2. Improve the performance of the request queuing functions by
- adding a last pointer to the queue structure.
- 3. Correct problems with reset and abort request handling that
- could have hung or crashed Linux.
- 4. Add more information to the adapter /proc file:
- /proc/scsi/advansys[0...].
- 5. Remove the request timeout issue form the driver issues list.
- 6. Miscellaneous documentation additions and changes.
-
- 1.8 (10/4/96):
- 1. Make changes to handle the new v2.1.0 kernel memory mapping
- in which a kernel virtual address may not be equivalent to its
- bus or DMA memory address.
- 2. Change abort and reset request handling to make it yet even
- more robust.
- 3. Try to mitigate request starvation by sending ordered requests
- to heavily loaded, tag queuing enabled devices.
- 4. Maintain statistics on request response time.
- 5. Add request response time statistics and other information to
- the adapter /proc file: /proc/scsi/advansys[0...].
-
- 1.9 (10/21/96):
- 1. Add conditionally compiled code (ASC_QUEUE_FLOW_CONTROL) to
- make use of mid-level SCSI driver device queue depth flow
- control mechanism. This will eliminate aborts caused by a
- device being unable to keep up with requests and eliminate
- repeat busy or QUEUE FULL status returned by a device.
- 2. Incorporate miscellaneous Asc Library bug fixes.
- 3. To allow the driver to work in kernels with broken module
- support set 'cmd_per_lun' if the driver is compiled as a
- module. This change affects kernels v1.3.89 to present.
- 4. Remove PCI BIOS address from the driver banner. The PCI BIOS
- is relocated by the motherboard BIOS and its new address can
- not be determined by the driver.
- 5. Add mid-level SCSI queue depth information to the adapter
- /proc file: /proc/scsi/advansys[0...].
-
- 2.0 (11/14/96):
- 1. Change allocation of global structures used for device
- initialization to guarantee they are in DMA-able memory.
- Previously when the driver was loaded as a module these
- structures might not have been in DMA-able memory, causing
- device initialization to fail.
-
- 2.1 (12/30/96):
- 1. In advansys_reset(), if the request is a synchronous reset
- request, even if the request serial number has changed, then
- complete the request.
- 2. Add Asc Library bug fixes including new microcode.
- 3. Clear inquiry buffer before using it.
- 4. Correct ifdef typo.
-
- 2.2 (1/15/97):
- 1. Add Asc Library bug fixes including new microcode.
- 2. Add synchronous data transfer rate information to the
- adapter /proc file: /proc/scsi/advansys[0...].
- 3. Change ADVANSYS_DEBUG to be disabled by default. This
- will reduce the size of the driver image, eliminate execution
- overhead, and remove unneeded symbols from the kernel symbol
- space that were previously added by the driver.
- 4. Add new compile-time option ADVANSYS_ASSERT for assertion
- code that used to be defined within ADVANSYS_DEBUG. This
- option is enabled by default.
-
- 2.8 (5/26/97):
- 1. Change version number to 2.8 to synchronize the Linux driver
- version numbering with other AdvanSys drivers.
- 2. Reformat source files without tabs to present the same view
- of the file to everyone regardless of the editor tab setting
- being used.
- 3. Add Asc Library bug fixes.
-
- 3.1A (1/8/98):
- 1. Change version number to 3.1 to indicate that support for
- Ultra-Wide adapters (ABP-940UW) is included in this release.
- 2. Add Asc Library (Narrow Board) bug fixes.
- 3. Report an underrun condition with the host status byte set
- to DID_UNDERRUN. Currently DID_UNDERRUN is defined to 0 which
- causes the underrun condition to be ignored. When Linux defines
- its own DID_UNDERRUN the constant defined in this file can be
- removed.
- 4. Add patch to AscWaitTixISRDone().
- 5. Add support for up to 16 different AdvanSys host adapter SCSI
- channels in one system. This allows four cards with four channels
- to be used in one system.
-
- 3.1B (1/9/98):
- 1. Handle that PCI register base addresses are not always page
- aligned even though ioremap() requires that the address argument
- be page aligned.
-
- 3.1C (1/10/98):
- 1. Update latest BIOS version checked for from the /proc file.
- 2. Don't set microcode SDTR variable at initialization. Instead
- wait until device capabilities have been detected from an Inquiry
- command.
-
- 3.1D (1/21/98):
- 1. Improve performance when the driver is compiled as module by
- allowing up to 64 scatter-gather elements instead of 8.
-
- 3.1E (5/1/98):
- 1. Set time delay in AscWaitTixISRDone() to 1000 ms.
- 2. Include SMP locking changes.
- 3. For v2.1.93 and newer kernels use CONFIG_PCI and new PCI BIOS
- access functions.
- 4. Update board serial number printing.
- 5. Try allocating an IRQ both with and without the IRQF_DISABLED
- flag set to allow IRQ sharing with drivers that do not set
- the IRQF_DISABLED flag. Also display a more descriptive error
- message if request_irq() fails.
- 6. Update to latest Asc and Adv Libraries.
-
- 3.2A (7/22/99):
- 1. Update Adv Library to 4.16 which includes support for
- the ASC38C0800 (Ultra2/LVD) IC.
-
- 3.2B (8/23/99):
- 1. Correct PCI compile time option for v2.1.93 and greater
- kernels, advansys_info() string, and debug compile time
- option.
- 2. Correct DvcSleepMilliSecond() for v2.1.0 and greater
- kernels. This caused an LVD detection/BIST problem problem
- among other things.
- 3. Sort PCI cards by PCI Bus, Slot, Function ascending order
- to be consistent with the BIOS.
- 4. Update to Asc Library S121 and Adv Library 5.2.
-
- 3.2C (8/24/99):
- 1. Correct PCI card detection bug introduced in 3.2B that
- prevented PCI cards from being detected in kernels older
- than v2.1.93.
-
- 3.2D (8/26/99):
- 1. Correct /proc device synchronous speed information display.
- Also when re-negotiation is pending for a target device
- note this condition with an * and footnote.
- 2. Correct initialization problem with Ultra-Wide cards that
- have a pre-3.2 BIOS. A microcode variable changed locations
- in 3.2 and greater BIOSes which caused WDTR to be attempted
- erroneously with drives that don't support WDTR.
-
- 3.2E (8/30/99):
- 1. Fix compile error caused by v2.3.13 PCI structure change.
- 2. Remove field from ASCEEP_CONFIG that resulted in an EEPROM
- checksum error for ISA cards.
- 3. Remove ASC_QUEUE_FLOW_CONTROL conditional code. The mid-level
- SCSI changes that it depended on were never included in Linux.
-
- 3.2F (9/3/99):
- 1. Handle new initial function code added in v2.3.16 for all
- driver versions.
-
- 3.2G (9/8/99):
- 1. Fix PCI board detection in v2.3.13 and greater kernels.
- 2. Fix comiple errors in v2.3.X with debugging enabled.
-
- 3.2H (9/13/99):
- 1. Add 64-bit address, long support for Alpha and UltraSPARC.
- The driver has been verified to work on an Alpha system.
- 2. Add partial byte order handling support for Power PC and
- other big-endian platforms. This support has not yet been
- completed or verified.
- 3. For wide boards replace block zeroing of request and
- scatter-gather structures with individual field initialization
- to improve performance.
- 4. Correct and clarify ROM BIOS version detection.
-
- 3.2I (10/8/99):
- 1. Update to Adv Library 5.4.
- 2. Add v2.3.19 underrun reporting to asc_isr_callback() and
- adv_isr_callback(). Remove DID_UNDERRUN constant and other
- no longer needed code that previously documented the lack
- of underrun handling.
-
- 3.2J (10/14/99):
- 1. Eliminate compile errors for v2.0 and earlier kernels.
-
- 3.2K (11/15/99):
- 1. Correct debug compile error in asc_prt_adv_scsi_req_q().
- 2. Update Adv Library to 5.5.
- 3. Add ifdef handling for /proc changes added in v2.3.28.
- 4. Increase Wide board scatter-gather list maximum length to
- 255 when the driver is compiled into the kernel.
-
- 3.2L (11/18/99):
- 1. Fix bug in adv_get_sglist() that caused an assertion failure
- at line 7475. The reqp->sgblkp pointer must be initialized

-
- 3.2M (11/29/99):
- 1. Really fix bug in adv_get_sglist().
- 2. Incorporate v2.3.29 changes into driver.
-
- 3.2N (4/1/00):
- 1. Add CONFIG_ISA ifdef code.
- 2. Include advansys_interrupts_enabled name change patch.
- 3. For >= v2.3.28 use new SCSI error handling with new function
- advansys_eh_bus_reset(). Don't include an abort function
- because of base library limitations.
- 4. For >= v2.3.28 use per board lock instead of io_request_lock.
- 5. For >= v2.3.28 eliminate advansys_command() and
- advansys_command_done().
- 6. Add some changes for PowerPC (Big Endian) support, but it isn't
- working yet.
- 7. Fix "nonexistent resource free" problem that occurred on a module
- unload for boards with an I/O space >= 255. The 'n_io_port' field
- is only one byte and can not be used to hold an ioport length more
- than 255.
-
- 3.3A (4/4/00):
- 1. Update to Adv Library 5.8.
- 2. For wide cards add support for CDBs up to 16 bytes.

-
- 3.3B (5/1/00):
- 1. Support for PowerPC (Big Endian) wide cards. Narrow cards
- still need work.
- 2. Change bitfields to shift and mask access for endian
- portability.
-
- 3.3C (10/13/00):
- 1. Update for latest 2.4 kernel.
- 2. Test ABP-480 CardBus support in 2.4 kernel - works!
- 3. Update to Asc Library S123.
- 4. Update to Adv Library 5.12.
-
- 3.3D (11/22/00):
- 1. Update for latest 2.4 kernel.
- 2. Create patches for 2.2 and 2.4 kernels.
-
- 3.3E (1/9/01):
- 1. Now that 2.4 is released remove ifdef code for kernel versions
- less than 2.2. The driver is now only supported in kernels 2.2,
- 2.4, and greater.
- 2. Add code to release and acquire the io_request_lock in
- the driver entrypoint functions: advansys_detect and
- advansys_queuecommand. In kernel 2.4 the SCSI mid-level driver
- still holds the io_request_lock on entry to SCSI low-level drivers.
- This was supposed to be removed before 2.4 was released but never
- happened. When the mid-level SCSI driver is changed all references
- to the io_request_lock should be removed from the driver.
- 3. Simplify error handling by removing advansys_abort(),
- AscAbortSRB(), AscResetDevice(). SCSI bus reset requests are
- now handled by resetting the SCSI bus and fully re-initializing
- the chip. This simple method of error recovery has proven to work
- most reliably after attempts at different methods. Also now only
- support the "new" error handling method and remove the obsolete
- error handling interface.
- 4. Fix debug build errors.
-
- 3.3F (1/24/01):
- 1. Merge with ConnectCom version from Andy Kellner which
- updates Adv Library to 5.14.
- 2. Make PowerPC (Big Endian) work for narrow cards and
- fix problems writing EEPROM for wide cards.
- 3. Remove interrupts_enabled assertion function.
-
- 3.3G (2/16/01):
- 1. Return an error from narrow boards if passed a 16 byte
- CDB. The wide board can already handle 16 byte CDBs.
-
- 3.3GJ (4/15/02):
- 1. hacks for lk 2.5 series (D. Gilbert)
-
- 3.3GJD (10/14/02):
- 1. change select_queue_depths to slave_configure
- 2. make cmd_per_lun be sane again
-
- 3.3K [2004/06/24]:
- 1. continuing cleanup for lk 2.6 series
- 2. Fix problem in lk 2.6.7-bk2 that broke PCI wide cards
- 3. Fix problem that oopsed ISA cards
-
- I. Known Problems/Fix List (XXX)
-
- 1. Need to add memory mapping workaround. Test the memory mapping.
- If it doesn't work revert to I/O port access. Can a test be done
- safely?
- 2. Handle an interrupt not working. Keep an interrupt counter in
- the interrupt handler. In the timeout function if the interrupt
- has not occurred then print a message and run in polled mode.
- 3. Allow bus type scanning order to be changed.
- 4. Need to add support for target mode commands, cf. CAM XPT.
-
- J. Credits (Chronological Order)
