-		Chapter 5: Functions
+		Chapter 5: Typedefs
+
+Please don't use things like "vps_t".
+
+It's a _mistake_ to use typedef for structures and pointers. When you see a
+
+	vps_t a;
+
+in the source, what does it mean?
+
+In contrast, if it says
+
+	struct virtual_container *a;
+
+you can actually tell what "a" is.
+
+Lots of people think that typedefs "help readability". Not so. They are
+useful only for:
+
+ (a) totally opaque objects (where the typedef is actively used to _hide_
+     what the object is).
+
+     Example: "pte_t" etc. opaque objects that you can only access using
+     the proper accessor functions.
+
+     NOTE! Opaqueness and "accessor functions" are not good in themselves.
+     The reason we have them for things like pte_t etc. is that there
+     really is absolutely _zero_ portably accessible information there.
+
+ (b) Clear integer types, where the abstraction _helps_ avoid confusion
+     whether it is "int" or "long".
+
+     u8/u16/u32 are perfectly fine typedefs, although they fit into
+     category (d) better than here.
+
+     NOTE! Again - there needs to be a _reason_ for this. If something is
+     "unsigned long", then there's no reason to do
+
+	typedef unsigned long myflags_t;
+
+     but if there is a clear reason for why it under certain circumstances
+     might be an "unsigned int" and under other configurations might be
+     "unsigned long", then by all means go ahead and use a typedef.
+
+ (c) when you use sparse to literally create a _new_ type for
+     type-checking.
+
+ (d) New types which are identical to standard C99 types, in certain
+     exceptional circumstances.
+
+     Although it would only take a short amount of time for the eyes and
+     brain to become accustomed to the standard types like 'uint32_t',
+     some people object to their use anyway.
+
+     Therefore, the Linux-specific 'u8/u16/u32/u64' types and their
+     signed equivalents which are identical to standard types are
+     permitted -- although they are not mandatory in new code of your
+     own.
+
+     When editing existing code which already uses one or the other set
+     of types, you should conform to the existing choices in that code.
+
+ (e) Types safe for use in userspace.
+
+     In certain structures which are visible to userspace, we cannot
+     require C99 types and cannot use the 'u32' form above. Thus, we
+     use __u32 and similar types in all structures which are shared
+     with userspace.
+
+Maybe there are other cases too, but the rule should basically be to NEVER
+EVER use a typedef unless you can clearly match one of those rules.
+
+In general, a pointer, or a struct that has elements that can reasonably
+be directly accessed should _never_ be a typedef.

+Linux Kernel patch sumbittal checklist
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here are some basic things that developers should do if they
+want to see their kernel patch submittals accepted quicker.
+
+These are all above and beyond the documentation that is provided
+in Documentation/SubmittingPatches and elsewhere about submitting
+Linux kernel patches.
+
+
+
+- Builds cleanly with applicable or modified CONFIG options =y, =m, and =n.
+  No gcc warnings/errors, no linker warnings/errors.
+
+- Passes allnoconfig, allmodconfig
+
+- Builds on multiple CPU arch-es by using local cross-compile tools
+  or something like PLM at OSDL.
+
+- ppc64 is a good architecture for cross-compilation checking because it
+  tends to use `unsigned long' for 64-bit quantities.
+
+- Matches kernel coding style(!)
+
+- Any new or modified CONFIG options don't muck up the config menu.
+
+- All new Kconfig options have help text.
+
+- Has been carefully reviewed with respect to relevant Kconfig
+  combinations.  This is very hard to get right with testing --
+  brainpower pays off here.
+
+- Check cleanly with sparse.
+
+- Use 'make checkstack' and 'make namespacecheck' and fix any
+  problems that they find.  Note:  checkstack does not point out
+  problems explicitly, but any one function that uses more than
+  512 bytes on the stack is a candidate for change.
+
+- Include kernel-doc to document global kernel APIs.  (Not required
+  for static functions, but OK there also.)  Use 'make htmldocs'
+  or 'make mandocs' to check the kernel-doc and fix any issues.
+
+- Has been tested with CONFIG_PREEMPT, CONFIG_DEBUG_PREEMPT,
+  CONFIG_DEBUG_SLAB, CONFIG_DEBUG_PAGEALLOC, CONFIG_DEBUG_MUTEXES,
+  CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_SPINLOCK_SLEEP all simultaneously
+  enabled.
+
+- Has been build- and runtime tested with and without CONFIG_SMP and
+  CONFIG_PREEMPT.
+
+- If the patch affects IO/Disk, etc: has been tested with and without
+  CONFIG_LBD.

+
+Interrupting filesystem operations
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If a process issuing a FUSE filesystem request is interrupted, the
+following will happen:
+
+  1) If the request is not yet sent to userspace AND the signal is
+     fatal (SIGKILL or unhandled fatal signal), then the request is
+     dequeued and returns immediately.
+
+  2) If the request is not yet sent to userspace AND the signal is not
+     fatal, then an 'interrupted' flag is set for the request.  When
+     the request has been successfully transfered to userspace and
+     this flag is set, an INTERRUPT request is queued.
+
+  3) If the request is already sent to userspace, then an INTERRUPT
+     request is queued.
+
+INTERRUPT requests take precedence over other requests, so the
+userspace filesystem will receive queued INTERRUPTs before any others.
+
+The userspace filesystem may ignore the INTERRUPT requests entirely,
+or may honor them by sending a reply to the _original_ request, with
+the error set to EINTR.
+
+It is also possible that there's a race between processing the
+original request and it's INTERRUPT request.  There are two possibilities:
+
+  1) The INTERRUPT request is processed before the original request is
+     processed
+
+  2) The INTERRUPT request is processed after the original request has
+     been answered
+
+If the filesystem cannot find the original request, it should wait for
+some timeout and/or a number of new requests to arrive, after which it
+should reply to the INTERRUPT request with an EAGAIN error.  In case
+1) the INTERRUPT request will be requeued.  In case 2) the INTERRUPT
+reply will be ignored.

+to minimize problems with permissions on directories that are unwritable or not
+searchable."  Don't do this when creating initramfs.cpio.gz images, it won't
+work.  The Linux kernel cpio extractor won't create files in a directory that
+doesn't exist, so the directory entries must go before the files that go in
+those directories.  The above script gets them in the right order.
+
+External initramfs images:
+--------------------------
+
+If the kernel has initrd support enabled, an external cpio.gz archive can also
+be passed into a 2.6 kernel in place of an initrd.  In this case, the kernel
+will autodetect the type (initramfs, not initrd) and extract the external cpio
+archive into rootfs before trying to run /init.
+
+This has the memory efficiency advantages of initramfs (no ramdisk block
+device) but the separate packaging of initrd (which is nice if you have
+non-GPL code you'd like to run from initramfs, without conflating it with
+the GPL licensed Linux kernel binary).
+
+It can also be used to supplement the kernel's built-in initamfs image.  The
+files in the external archive will overwrite any conflicting files in
+the built-in initramfs archive.  Some distributors also prefer to customize
+a single kernel image with task-specific initramfs images, without recompiling.

+
+Description
+-----------
+
+This driver supports the hardware monitoring features of the Abit uGuru chip
+found on Abit uGuru featuring motherboards (most modern Abit motherboards).
+
+The uGuru chip in reality is a Winbond W83L950D in disguise (despite Abit
+claiming it is "a new microprocessor designed by the ABIT Engineers").
+Unfortunatly this doesn't help since the W83L950D is a generic
+microcontroller with a custom Abit application running on it.
+
+Despite Abit not releasing any information regarding the uGuru, Olle
+Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
+of the uGuru. Without his work this driver would not have been possible.
+
+Known Issues
+------------
+
+The voltage and frequency control parts of the Abit uGuru are not supported.

+uGuru datasheet
+===============
+
+First of all, what I know about uGuru is no fact based on any help, hints or
+datasheet from Abit. The data I have got on uGuru have I assembled through
+my weak knowledge in "backwards engineering".
+And just for the record, you may have noticed uGuru isn't a chip developed by
+Abit, as they claim it to be. It's realy just an microprocessor (uC) created by
+Winbond (W83L950D). And no, reading the manual for this specific uC or
+mailing  Windbond for help won't give any usefull data about uGuru, as it is
+the program inside the uC that is responding to calls.
+
+Olle Sandberg <ollebull@gmail.com>, 2005-05-25
+
+
+Original version by Olle Sandberg who did the heavy lifting of the initial
+reverse engineering. This version has been almost fully rewritten for clarity
+and extended with write support and info on more databanks, the write support
+is once again reverse engineered by Olle the additional databanks have been
+reverse engineered by me. I would like to express my thanks to Olle, this
+document and the Linux driver could not have been written without his efforts.
+
+Note: because of the lack of specs only the sensors part of the uGuru is
+described here and not the CPU / RAM / etc voltage & frequency control.
+
+Hans de Goede <j.w.r.degoede@hhs.nl>, 28-01-2006
+
+
+Detection
+=========
+
+As far as known the uGuru is always placed at and using the (ISA) I/O-ports
+0xE0 and 0xE4, so we don't have to scan any port-range, just check what the two
+ports are holding for detection. We will refer to 0xE0 as CMD (command-port)
+and 0xE4 as DATA because Abit refers to them with these names.
+
+If DATA holds 0x00 or 0x08 and CMD holds 0x00 or 0xAC an uGuru could be
+present. We have to check for two different values at data-port, because
+after a reboot uGuru will hold 0x00 here, but if the driver is removed and
+later on attached again data-port will hold 0x08, more about this later.
+
+After wider testing of the Linux kernel driver some variants of the uGuru have
+turned up which will hold 0x00 instead of 0xAC at the CMD port, thus we also
+have to test CMD for two different values. On these uGuru's DATA will initally
+hold 0x09 and will only hold 0x08 after reading CMD first, so CMD must be read
+first!
+
+To be really sure an uGuru is present a test read of one or more register
+sets should be done.
+
+
+Reading / Writing
+=================
+
+Addressing
+----------
+
+The uGuru has a number of different addressing levels. The first addressing
+level we will call banks. A bank holds data for one or more sensors. The data
+in a bank for a sensor is one or more bytes large.
+
+The number of bytes is fixed for a given bank, you should always read or write
+that many bytes, reading / writing more will fail, the results when writing
+less then the number of bytes for a given bank are undetermined.
+
+See below for all known bank addresses, numbers of sensors in that bank,
+number of bytes data per sensor and contents/meaning of those bytes.
+
+Although both this document and the kernel driver have kept the sensor
+terminoligy for the addressing within a bank this is not 100% correct, in
+bank 0x24 for example the addressing within the bank selects a PWM output not
+a sensor.
+
+Notice that some banks have both a read and a write address this is how the
+uGuru determines if a read from or a write to the bank is taking place, thus
+when reading you should always use the read address and when writing the
+write address. The write address is always one (1) more then the read address.
+
+
+uGuru ready
+-----------
+
+Before you can read from or write to the uGuru you must first put the uGuru
+in "ready" mode.
+
+To put the uGuru in ready mode first write 0x00 to DATA and then wait for DATA
+to hold 0x09, DATA should read 0x09 within 250 read cycles.
+
+Next CMD _must_ be read and should hold 0xAC, usually CMD will hold 0xAC the
+first read but sometimes it takes a while before CMD holds 0xAC and thus it
+has to be read a number of times (max 50).
+
+After reading CMD, DATA should hold 0x08 which means that the uGuru is ready
+for input. As above DATA will usually hold 0x08 the first read but not always.
+This step can be skipped, but it is undetermined what happens if the uGuru has
+not yet reported 0x08 at DATA and you proceed with writing a bank address.
+
+
+Sending bank and sensor addresses to the uGuru
+----------------------------------------------
+
+First the uGuru must be in "ready" mode as described above, DATA should hold
+0x08 indicating that the uGuru wants input, in this case the bank address.
+
+Next write the bank address to DATA. After the bank address has been written
+wait for to DATA to hold 0x08 again indicating that it wants / is ready for
+more input (max 250 reads).
+
+Once DATA holds 0x08 again write the sensor address to CMD.
+
+
+Reading
+-------
+
+First send the bank and sensor addresses as described above.
+Then for each byte of data you want to read wait for DATA to hold 0x01
+which indicates that the uGuru is ready to be read (max 250 reads) and once
+DATA holds 0x01 read the byte from CMD.
+
+Once all bytes have been read data will hold 0x09, but there is no reason to
+test for this. Notice that the number of bytes is bank address dependent see
+above and below.
+
+After completing a successfull read it is advised to put the uGuru back in
+ready mode, so that it is ready for the next read / write cycle. This way
+if your program / driver is unloaded and later loaded again the detection
+algorithm described above will still work.
+
+
+
+Writing
+-------
+
+First send the bank and sensor addresses as described above.
+Then for each byte of data you want to write wait for DATA to hold 0x00
+which indicates that the uGuru is ready to be written (max 250 reads) and
+once DATA holds 0x00 write the byte to CMD.
+
+Once all bytes have been written wait for DATA to hold 0x01 (max 250 reads)
+don't ask why this is the way it is.
+
+Once DATA holds 0x01 read CMD it should hold 0xAC now.
+
+After completing a successfull write it is advised to put the uGuru back in
+ready mode, so that it is ready for the next read / write cycle. This way
+if your program / driver is unloaded and later loaded again the detection
+algorithm described above will still work.
+
+
+Gotchas
+-------
+
+After wider testing of the Linux kernel driver some variants of the uGuru have
+turned up which do not hold 0x08 at DATA within 250 reads after writing the
+bank address. With these versions this happens quite frequent, using larger
+timeouts doesn't help, they just go offline for a second or 2, doing some
+internal callibration or whatever. Your code should be prepared to handle
+this and in case of no response in this specific case just goto sleep for a
+while and then retry.

+volt and temp sensors, this is motherboard specific. The uGuru however does
+seem to know (be programmed with) what kindoff sensor is attached see Sensor
+Bank1 Settings description.
+
+Volt sensors use a linear scale, a reading 0 corresponds with 0 volt and a
+reading of 255 with 3494 mV. The sensors for higher voltages however are
+connected through a division circuit. The currently known division circuits
+in use result in ranges of: 0-4361mV, 0-6248mV or 0-14510mV. 3.3 volt sources
+use the 0-4361mV range, 5 volt the 0-6248mV and 12 volt the 0-14510mV .

+Warning for the adventerous
+===========================
+
+A word of caution to those who want to experiment and see if they can figure
+the voltage / clock programming out, I tried reading and only reading banks
+0-0x30 with the reading code used for the sensor banks (0x20-0x28) and this
+resulted in a _permanent_ reprogramming of the voltages, luckily I had the
+sensors part configured so that it would shutdown my system on any out of spec
+voltages which proprably safed my computer (after a reboot I managed to
+immediatly enter the bios and reload the defaults). This probably means that
+the read/write cycle for the non sensor part is different from the sensor part.

+Description
+-----------
+
+This driver implements support for the National Semiconductor LM70
+temperature sensor.
+
+The LM70 temperature sensor chip supports a single temperature sensor.
+It communicates with a host processor (or microcontroller) via an
+SPI/Microwire Bus interface.
+

+Description
+-----------
+
+This driver implements support for the hardware sensor capabilities
+of the SMSC LPC47M192 and LPC47M997 Super-I/O chips.
+
+These chips support 3 temperature channels and 8 voltage inputs
+as well as CPU voltage VID input.
+
+They do also have fan monitoring and control capabilities, but the
+these features are accessed via ISA bus and are not supported by this
+driver. Use the 'smsc47m1' driver for fan monitoring and control.
+
+Voltages and temperatures are measured by an 8-bit ADC, the resolution
+of the temperatures is 1 bit per degree C.
+Voltages are scaled such that the nominal voltage corresponds to
+192 counts, i.e. 3/4 of the full range. Thus the available range for
+each voltage channel is 0V ... 255/192*(nominal voltage), the resolution
+is 1 bit per (nominal voltage)/192.
+Both voltage and temperature values are scaled by 1000, the sys files
+show voltages in mV and temperatures in units of 0.001 degC.
+
+The +12V analog voltage input channel (in4_input) is multiplexed with
+bit 4 of the encoded CPU voltage. This means that you either get
+a +12V voltage measurement or a 5 bit CPU VID, but not both.
+The default setting is to use the pin as 12V input, and use only 4 bit VID.
+This driver assumes that the information in the configuration register
+is correct, i.e. that the BIOS has updated the configuration if
+the motherboard has this input wired to VID4.
+
+The temperature and voltage readings are updated once every 1.5 seconds.
+Reading them more often repeats the same values.

+
+Description
+-----------
+
+This driver implements support for the Winbond W83791D chip.
+
+Detection of the chip can sometimes be foiled because it can be in an
+internal state that allows no clean access (Bank with ID register is not
+currently selected). If you know the address of the chip, use a 'force'
+parameter; this will put it into a more well-behaved state first.
+
+The driver implements three temperature sensors, five fan rotation speed
+sensors, and ten voltage sensors.
+
+Temperatures are measured in degrees Celsius and measurement resolution is 1
+degC for temp1 and 0.5 degC for temp2 and temp3. An alarm is triggered when
+the temperature gets higher than the Overtemperature Shutdown value; it stays
+on until the temperature falls below the Hysteresis value.
+
+Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
+triggered if the rotation speed has dropped below a programmable limit. Fan
+readings can be divided by a programmable divider (1, 2, 4, 8 for fan 1/2/3
+and 1, 2, 4, 8, 16, 32, 64 or 128 for fan 4/5) to give the readings more
+range or accuracy.
+
+Voltage sensors (also known as IN sensors) report their values in millivolts.
+An alarm is triggered if the voltage has crossed a programmable minimum
+or maximum limit.
+
+Alarms are provided as output from a "realtime status register". The
+following bits are defined:
+
+bit - alarm on:
+0  - Vcore
+1  - VINR0
+2  - +3.3VIN
+3  - 5VDD
+4  - temp1
+5  - temp2
+6  - fan1
+7  - fan2
+8  - +12VIN
+9  - -12VIN
+10 - -5VIN
+11 - fan3
+12 - chassis
+13 - temp3
+14 - VINR1
+15 - reserved
+16 - tart1
+17 - tart2
+18 - tart3
+19 - VSB
+20 - VBAT
+21 - fan4
+22 - fan5
+23 - reserved
+
+When an alarm goes off, you can be warned by a beeping signal through your
+computer speaker. It is possible to enable all beeping globally, or only
+the beeping for some alarms.
+
+The driver only reads the chip values each 3 seconds; reading them more
+often will do no harm, but will return 'old' values.

+Description
+-----------
+
+i2c-ocores is an i2c bus driver for the OpenCores.org I2C controller
+IP core by Richard Herveille.
+
+Usage
+-----
+
+i2c-ocores uses the platform bus, so you need to provide a struct
+platform_device with the base address and interrupt number. The
+dev.platform_data of the device should also point to a struct
+ocores_i2c_platform_data (see linux/i2c-ocores.h) describing the
+distance between registers and the input clock speed.
+
+E.G. something like:
+
+static struct resource ocores_resources[] = {
+	[0] = {
+		.start	= MYI2C_BASEADDR,
+		.end	= MYI2C_BASEADDR + 8,
+		.flags	= IORESOURCE_MEM,
+	},
+	[1] = {
+		.start	= MYI2C_IRQ,
+		.end	= MYI2C_IRQ,
+		.flags	= IORESOURCE_IRQ,
+	},
+};
+
+static struct ocores_i2c_platform_data myi2c_data = {
+	.regstep	= 2,		/* two bytes between registers */
+	.clock_khz	= 50000,	/* input clock of 50MHz */
+};
+
+static struct platform_device myi2c = {
+	.name			= "ocores-i2c",
+	.dev = {
+		.platform_data	= &myi2c_data,
+	},
+	.num_resources		= ARRAY_SIZE(ocores_resources),
+	.resource		= ocores_resources,
+};

+	         MEMORY ATTRIBUTE ALIASING ON IA-64
+
+			   Bjorn Helgaas
+		       <bjorn.helgaas@hp.com>
+			    May 4, 2006
+
+
+MEMORY ATTRIBUTES
+
+    Itanium supports several attributes for virtual memory references.
+    The attribute is part of the virtual translation, i.e., it is
+    contained in the TLB entry.  The ones of most interest to the Linux
+    kernel are:
+
+	WB		Write-back (cacheable)
+	UC		Uncacheable
+	WC		Write-coalescing
+
+    System memory typically uses the WB attribute.  The UC attribute is
+    used for memory-mapped I/O devices.  The WC attribute is uncacheable
+    like UC is, but writes may be delayed and combined to increase
+    performance for things like frame buffers.
+
+    The Itanium architecture requires that we avoid accessing the same
+    page with both a cacheable mapping and an uncacheable mapping[1].
+
+    The design of the chipset determines which attributes are supported
+    on which regions of the address space.  For example, some chipsets
+    support either WB or UC access to main memory, while others support
+    only WB access.
+
+MEMORY MAP
+
+    Platform firmware describes the physical memory map and the
+    supported attributes for each region.  At boot-time, the kernel uses
+    the EFI GetMemoryMap() interface.  ACPI can also describe memory
+    devices and the attributes they support, but Linux/ia64 currently
+    doesn't use this information.
+
+    The kernel uses the efi_memmap table returned from GetMemoryMap() to
+    learn the attributes supported by each region of physical address
+    space.  Unfortunately, this table does not completely describe the
+    address space because some machines omit some or all of the MMIO
+    regions from the map.
+
+    The kernel maintains another table, kern_memmap, which describes the
+    memory Linux is actually using and the attribute for each region.
+    This contains only system memory; it does not contain MMIO space.
+
+    The kern_memmap table typically contains only a subset of the system
+    memory described by the efi_memmap.  Linux/ia64 can't use all memory
+    in the system because of constraints imposed by the identity mapping
+    scheme.
+
+    The efi_memmap table is preserved unmodified because the original
+    boot-time information is required for kexec.
+
+KERNEL IDENTITY MAPPINGS
+
+    Linux/ia64 identity mappings are done with large pages, currently
+    either 16MB or 64MB, referred to as "granules."  Cacheable mappings
+    are speculative[2], so the processor can read any location in the
+    page at any time, independent of the programmer's intentions.  This
+    means that to avoid attribute aliasing, Linux can create a cacheable
+    identity mapping only when the entire granule supports cacheable
+    access.
+
+    Therefore, kern_memmap contains only full granule-sized regions that
+    can referenced safely by an identity mapping.
+
+    Uncacheable mappings are not speculative, so the processor will
+    generate UC accesses only to locations explicitly referenced by
+    software.  This allows UC identity mappings to cover granules that
+    are only partially populated, or populated with a combination of UC
+    and WB regions.
+
+USER MAPPINGS
+
+    User mappings are typically done with 16K or 64K pages.  The smaller
+    page size allows more flexibility because only 16K or 64K has to be
+    homogeneous with respect to memory attributes.
+
+POTENTIAL ATTRIBUTE ALIASING CASES
+
+    There are several ways the kernel creates new mappings:
+
+    mmap of /dev/mem
+
+	This uses remap_pfn_range(), which creates user mappings.  These
+	mappings may be either WB or UC.  If the region being mapped
+	happens to be in kern_memmap, meaning that it may also be mapped
+	by a kernel identity mapping, the user mapping must use the same
+	attribute as the kernel mapping.
+
+	If the region is not in kern_memmap, the user mapping should use
+	an attribute reported as being supported in the EFI memory map.
+
+	Since the EFI memory map does not describe MMIO on some
+	machines, this should use an uncacheable mapping as a fallback.
+
+    mmap of /sys/class/pci_bus/.../legacy_mem
+
+	This is very similar to mmap of /dev/mem, except that legacy_mem
+	only allows mmap of the one megabyte "legacy MMIO" area for a
+	specific PCI bus.  Typically this is the first megabyte of
+	physical address space, but it may be different on machines with
+	several VGA devices.
+
+	"X" uses this to access VGA frame buffers.  Using legacy_mem
+	rather than /dev/mem allows multiple instances of X to talk to
+	different VGA cards.
+
+	The /dev/mem mmap constraints apply.
+
+	However, since this is for mapping legacy MMIO space, WB access
+	does not make sense.  This matters on machines without legacy
+	VGA support: these machines may have WB memory for the entire
+	first megabyte (or even the entire first granule).
+
+	On these machines, we could mmap legacy_mem as WB, which would
+	be safe in terms of attribute aliasing, but X has no way of
+	knowing that it is accessing regular memory, not a frame buffer,
+	so the kernel should fail the mmap rather than doing it with WB.
+
+    read/write of /dev/mem
+
+	This uses copy_from_user(), which implicitly uses a kernel
+	identity mapping.  This is obviously safe for things in
+	kern_memmap.
+
+	There may be corner cases of things that are not in kern_memmap,
+	but could be accessed this way.  For example, registers in MMIO
+	space are not in kern_memmap, but could be accessed with a UC
+	mapping.  This would not cause attribute aliasing.  But
+	registers typically can be accessed only with four-byte or
+	eight-byte accesses, and the copy_from_user() path doesn't allow
+	any control over the access size, so this would be dangerous.
+
+    ioremap()
+
+	This returns a kernel identity mapping for use inside the
+	kernel.
+
+	If the region is in kern_memmap, we should use the attribute
+	specified there.  Otherwise, if the EFI memory map reports that
+	the entire granule supports WB, we should use that (granules
+	that are partially reserved or occupied by firmware do not appear
+	in kern_memmap).  Otherwise, we should use a UC mapping.
+
+PAST PROBLEM CASES
+
+    mmap of various MMIO regions from /dev/mem by "X" on Intel platforms
+
+      The EFI memory map may not report these MMIO regions.
+
+      These must be allowed so that X will work.  This means that
+      when the EFI memory map is incomplete, every /dev/mem mmap must
+      succeed.  It may create either WB or UC user mappings, depending
+      on whether the region is in kern_memmap or the EFI memory map.
+
+    mmap of 0x0-0xA0000 /dev/mem by "hwinfo" on HP sx1000 with VGA enabled
+
+      See https://bugzilla.novell.com/show_bug.cgi?id=140858.
+
+      The EFI memory map reports the following attributes:
+        0x00000-0x9FFFF WB only
+        0xA0000-0xBFFFF UC only (VGA frame buffer)
+        0xC0000-0xFFFFF WB only
+
+      This mmap is done with user pages, not kernel identity mappings,
+      so it is safe to use WB mappings.
+
+      The kernel VGA driver may ioremap the VGA frame buffer at 0xA0000,
+      which will use a granule-sized UC mapping covering 0-0xFFFFF.  This
+      granule covers some WB-only memory, but since UC is non-speculative,
+      the processor will never generate an uncacheable reference to the
+      WB-only areas unless the driver explicitly touches them.
+
+    mmap of 0x0-0xFFFFF legacy_mem by "X"
+
+      If the EFI memory map reports this entire range as WB, there
+      is no VGA MMIO hole, and the mmap should fail or be done with
+      a WB mapping.
+
+      There's no easy way for X to determine whether the 0xA0000-0xBFFFF
+      region is a frame buffer or just memory, so I think it's best to
+      just fail this mmap request rather than using a WB mapping.  As
+      far as I know, there's no need to map legacy_mem with WB
+      mappings.
+
+      Otherwise, a UC mapping of the entire region is probably safe.
+      The VGA hole means the region will not be in kern_memmap.  The
+      HP sx1000 chipset doesn't support UC access to the memory surrounding
+      the VGA hole, but X doesn't need that area anyway and should not
+      reference it.
+
+    mmap of 0xA0000-0xBFFFF legacy_mem by "X" on HP sx1000 with VGA disabled
+
+      The EFI memory map reports the following attributes:
+        0x00000-0xFFFFF WB only (no VGA MMIO hole)
+
+      This is a special case of the previous case, and the mmap should
+      fail for the same reason as above.

-Documentation for kdump - the kexec-based crash dumping solution
+================================================================
+Documentation for Kdump - The kexec-based Crash Dumping Solution
 ================================================================
 
-DESIGN
-======
+This document includes overview, setup and installation, and analysis
+information.
 
-Kdump uses kexec to reboot to a second kernel whenever a dump needs to be
-taken. This second kernel is booted with very little memory. The first kernel
-reserves the section of memory that the second kernel uses. This ensures that
-on-going DMA from the first kernel does not corrupt the second kernel.
+Overview
+========
 
-All the necessary information about Core image is encoded in ELF format and
-stored in reserved area of memory before crash. Physical address of start of
-ELF header is passed to new kernel through command line parameter elfcorehdr=.
+Kdump uses kexec to quickly boot to a dump-capture kernel whenever a
+dump of the system kernel's memory needs to be taken (for example, when
+the system panics). The system kernel's memory image is preserved across
+the reboot and is accessible to the dump-capture kernel.
 
-On i386, the first 640 KB of physical memory is needed to boot, irrespective
-of where the kernel loads. Hence, this region is backed up by kexec just before
-rebooting into the new kernel.
+You can use common Linux commands, such as cp and scp, to copy the
+memory image to a dump file on the local disk, or across the network to
+a remote system.
 
-In the second kernel, "old memory" can be accessed in two ways.
+Kdump and kexec are currently supported on the x86, x86_64, and ppc64
+architectures.
 
-- The first one is through a /dev/oldmem device interface. A capture utility
-  can read the device file and write out the memory in raw format. This is raw
-  dump of memory and analysis/capture tool should be intelligent enough to
-  determine where to look for the right information. ELF headers (elfcorehdr=)
-  can become handy here.
+When the system kernel boots, it reserves a small section of memory for
+the dump-capture kernel. This ensures that ongoing Direct Memory Access
+(DMA) from the system kernel does not corrupt the dump-capture kernel.
+The kexec -p command loads the dump-capture kernel into this reserved
+memory.
 
-- The second interface is through /proc/vmcore. This exports the dump as an ELF
-  format file which can be written out using any file copy command
-  (cp, scp, etc). Further, gdb can be used to perform limited debugging on
-  the dump file. This method ensures methods ensure that there is correct
-  ordering of the dump pages (corresponding to the first 640 KB that has been
-  relocated).
+On x86 machines, the first 640 KB of physical memory is needed to boot,
+regardless of where the kernel loads. Therefore, kexec backs up this
+region just before rebooting into the dump-capture kernel.
 
-SETUP
-=====
+All of the necessary information about the system kernel's core image is
+encoded in the ELF format, and stored in a reserved area of memory
+before a crash. The physical address of the start of the ELF header is
+passed to the dump-capture kernel through the elfcorehdr= boot
+parameter.
+
+With the dump-capture kernel, you can access the memory image, or "old
+memory," in two ways:
+
+- Through a /dev/oldmem device interface. A capture utility can read the
+  device file and write out the memory in raw format. This is a raw dump
+  of memory. Analysis and capture tools must be intelligent enough to
+  determine where to look for the right information.
+
+- Through /proc/vmcore. This exports the dump as an ELF-format file that
+  you can write out using file copy commands such as cp or scp. Further,
+  you can use analysis tools such as the GNU Debugger (GDB) and the Crash
+  tool to debug the dump file. This method ensures that the dump pages are
+  correctly ordered.
+

+
+Download and build the system and dump-capture kernels
+------------------------------------------------------
+
+Download the mainline (vanilla) kernel source code (2.6.13-rc1 or newer)
+from http://www.kernel.org. Two kernels must be built: a system kernel
+and a dump-capture kernel. Use the following steps to configure these
+kernels with the necessary kexec and Kdump features:
+
+System kernel
+-------------
+
+1) Enable "kexec system call" in "Processor type and features."
+
+   CONFIG_KEXEC=y
+
+2) Enable "sysfs file system support" in "Filesystem" -> "Pseudo
+   filesystems." This is usually enabled by default.
+
+   CONFIG_SYSFS=y
+
+   Note that "sysfs file system support" might not appear in the "Pseudo
+   filesystems" menu if "Configure standard kernel features (for small
+   systems)" is not enabled in "General Setup." In this case, check the
+   .config file itself to ensure that sysfs is turned on, as follows:
+
+   grep 'CONFIG_SYSFS' .config
+
+3) Enable "Compile the kernel with debug info" in "Kernel hacking."
+
+   CONFIG_DEBUG_INFO=Y
+
+   This causes the kernel to be built with debug symbols. The dump
+   analysis tools require a vmlinux with debug symbols in order to read
+   and analyze a dump file.
+
+4) Make and install the kernel and its modules. Update the boot loader
+   (such as grub, yaboot, or lilo) configuration files as necessary.
+
+5) Boot the system kernel with the boot parameter "crashkernel=Y@X",
+   where Y specifies how much memory to reserve for the dump-capture kernel
+   and X specifies the beginning of this reserved memory. For example,
+   "crashkernel=64M@16M" tells the system kernel to reserve 64 MB of memory
+   starting at physical address 0x01000000 for the dump-capture kernel.
+
+   On x86 and x86_64, use "crashkernel=64M@16M".
+
+   On ppc64, use "crashkernel=128M@32M".
+
+
+The dump-capture kernel
+-----------------------
 
-1) Download the upstream kexec-tools userspace package from
-   http://www.xmission.com/~ebiederm/files/kexec/kexec-tools-1.101.tar.gz.
-
-   Apply the latest consolidated kdump patch on top of kexec-tools-1.101
-   from http://lse.sourceforge.net/kdump/. This arrangment has been made
-   till all the userspace patches supporting kdump are integrated with
-   upstream kexec-tools userspace.
-
-2) Download and build the appropriate (2.6.13-rc1 onwards) vanilla kernels.
-   Two kernels need to be built in order to get this feature working.
-   Following are the steps to properly configure the two kernels specific
-   to kexec and kdump features:
-
-  A) First kernel or regular kernel:
-  ----------------------------------
-   a) Enable "kexec system call" feature (in Processor type and features).
-      CONFIG_KEXEC=y
-   b) Enable "sysfs file system support" (in Pseudo filesystems).
-      CONFIG_SYSFS=y
-   c) make
-   d) Boot into first kernel with the command line parameter "crashkernel=Y@X".
-      Use appropriate values for X and Y. Y denotes how much memory to reserve
-      for the second kernel, and X denotes at what physical address the
-      reserved memory section starts. For example: "crashkernel=64M@16M".
-
-
-  B) Second kernel or dump capture kernel:
-  ---------------------------------------
-   a) For i386 architecture enable Highmem support
-      CONFIG_HIGHMEM=y
-   b) Enable "kernel crash dumps" feature (under "Processor type and features")
-      CONFIG_CRASH_DUMP=y
-   c) Make sure a suitable value for "Physical address where the kernel is
-      loaded" (under "Processor type and features"). By default this value
-      is 0x1000000 (16MB) and it should be same as X (See option d above),
-      e.g., 16 MB or 0x1000000.
-      CONFIG_PHYSICAL_START=0x1000000
-   d) Enable "/proc/vmcore support" (Optional, under "Pseudo filesystems").
-      CONFIG_PROC_VMCORE=y
-
-3) After booting to regular kernel or first kernel, load the second kernel
-   using the following command:
-
-   kexec -p <second-kernel> --args-linux --elf32-core-headers
-   --append="root=<root-dev> init 1 irqpoll maxcpus=1"
-
-   Notes:
-   ======
-     i) <second-kernel> has to be a vmlinux image ie uncompressed elf image.
-        bzImage will not work, as of now.
-    ii) --args-linux has to be speicfied as if kexec it loading an elf image,
-        it needs to know that the arguments supplied are of linux type.
-   iii) By default ELF headers are stored in ELF64 format to support systems
-        with more than 4GB memory. Option --elf32-core-headers forces generation
-        of ELF32 headers. The reason for this option being, as of now gdb can
-        not open vmcore file with ELF64 headers on a 32 bit systems. So ELF32
-        headers can be used if one has non-PAE systems and hence memory less
-        than 4GB.
-    iv) Specify "irqpoll" as command line parameter. This reduces driver
-         initialization failures in second kernel due to shared interrupts.
-     v) <root-dev> needs to be specified in a format corresponding to the root
-        device name in the output of mount command.
-    vi) If you have built the drivers required to mount root file system as
-        modules in <second-kernel>, then, specify
-        --initrd=<initrd-for-second-kernel>.
-   vii) Specify maxcpus=1 as, if during first kernel run, if panic happens on
-        non-boot cpus, second kernel doesn't seem to be boot up all the cpus.
-        The other option is to always built the second kernel without SMP
-        support ie CONFIG_SMP=n
-
-4) After successfully loading the second kernel as above, if a panic occurs
-   system reboots into the second kernel. A module can be written to force
-   the panic or "ALT-SysRq-c" can be used initiate a crash dump for testing
-   purposes.
-
-5) Once the second kernel has booted, write out the dump file using
+1) Under "General setup," append "-kdump" to the current string in
+   "Local version."
+
+2) On x86, enable high memory support under "Processor type and
+   features":
+
+   CONFIG_HIGHMEM64G=y
+   or
+   CONFIG_HIGHMEM4G
+
+3) On x86 and x86_64, disable symmetric multi-processing support
+   under "Processor type and features":
+
+   CONFIG_SMP=n
+   (If CONFIG_SMP=y, then specify maxcpus=1 on the kernel command line
+   when loading the dump-capture kernel, see section "Load the Dump-capture
+   Kernel".)
+
+4) On ppc64, disable NUMA support and enable EMBEDDED support:
+
+   CONFIG_NUMA=n
+   CONFIG_EMBEDDED=y
+   CONFIG_EEH=N for the dump-capture kernel
+
+5) Enable "kernel crash dumps" support under "Processor type and
+   features":
+
+   CONFIG_CRASH_DUMP=y
+
+6) Use a suitable value for "Physical address where the kernel is
+   loaded" (under "Processor type and features"). This only appears when
+   "kernel crash dumps" is enabled. By default this value is 0x1000000
+   (16MB). It should be the same as X in the "crashkernel=Y@X" boot
+   parameter discussed above.
+
+   On x86 and x86_64, use "CONFIG_PHYSICAL_START=0x1000000".
+
+   On ppc64 the value is automatically set at 32MB when
+   CONFIG_CRASH_DUMP is set.
+
+6) Optionally enable "/proc/vmcore support" under "Filesystems" ->
+   "Pseudo filesystems".
+
+   CONFIG_PROC_VMCORE=y
+   (CONFIG_PROC_VMCORE is set by default when CONFIG_CRASH_DUMP is selected.)
+
+7) Make and install the kernel and its modules. DO NOT add this kernel
+   to the boot loader configuration files.
+
+
+Load the Dump-capture Kernel
+============================
+
+After booting to the system kernel, load the dump-capture kernel using
+the following command:
+
+   kexec -p <dump-capture-kernel> \
+   --initrd=<initrd-for-dump-capture-kernel> --args-linux \
+   --append="root=<root-dev> init 1 irqpoll"
+
+
+Notes on loading the dump-capture kernel:
+
+* <dump-capture-kernel> must be a vmlinux image (that is, an
+  uncompressed ELF image). bzImage does not work at this time.
+
+* By default, the ELF headers are stored in ELF64 format to support
+  systems with more than 4GB memory. The --elf32-core-headers option can
+  be used to force the generation of ELF32 headers. This is necessary
+  because GDB currently cannot open vmcore files with ELF64 headers on
+  32-bit systems. ELF32 headers can be used on non-PAE systems (that is,
+  less than 4GB of memory).
+
+* The "irqpoll" boot parameter reduces driver initialization failures
+  due to shared interrupts in the dump-capture kernel.
+
+* You must specify <root-dev> in the format corresponding to the root
+  device name in the output of mount command.
+
+* "init 1" boots the dump-capture kernel into single-user mode without
+  networking. If you want networking, use "init 3."
+
+
+Kernel Panic
+============
+
+After successfully loading the dump-capture kernel as previously
+described, the system will reboot into the dump-capture kernel if a
+system crash is triggered.  Trigger points are located in panic(),
+die(), die_nmi() and in the sysrq handler (ALT-SysRq-c).
+
+The following conditions will execute a crash trigger point:
+
+If a hard lockup is detected and "NMI watchdog" is configured, the system
+will boot into the dump-capture kernel ( die_nmi() ).
+
+If die() is called, and it happens to be a thread with pid 0 or 1, or die()
+is called inside interrupt context or die() is called and panic_on_oops is set,
+the system will boot into the dump-capture kernel.
+
+On powererpc systems when a soft-reset is generated, die() is called by all cpus and the system system will boot into the dump-capture kernel.
+
+For testing purposes, you can trigger a crash by using "ALT-SysRq-c",
+"echo c > /proc/sysrq-trigger or write a module to force the panic.
+
+Write Out the Dump File
+=======================
+
+After the dump-capture kernel is booted, write out the dump file with
+the following command:
 
    cp /proc/vmcore <dump-file>
 
-   Dump memory can also be accessed as a /dev/oldmem device for a linear/raw
-   view.  To create the device, type:

 Q: Is this true that if I have a mounted filesystem on a USB device and
 I suspend to disk, I can lose data unless the filesystem has been mounted
@@ -380,3 +405,17 @@ safest thing is to unmount all filesystems on removable media (such USB,
 Firewire, CompactFlash, MMC, external SATA, or even IDE hotplug bays)
 before suspending; then remount them after resuming.
 
+Q: I upgraded the kernel from 2.6.15 to 2.6.16. Both kernels were
+compiled with the similar configuration files. Anyway I found that
+suspend to disk (and resume) is much slower on 2.6.16 compared to
+2.6.15. Any idea for why that might happen or how can I speed it up?
+
+A: This is because the size of the suspend image is now greater than
+for 2.6.15 (by saving more data we can get more responsive system
+after resume).
+
+There's the /sys/power/image_size knob that controls the size of the
+image.  If you set it to 0 (eg. by echo 0 > /sys/power/image_size as
+root), the 2.6.15 behavior should be restored.  If it is still too
+slow, take a look at suspend.sf.net -- userland suspend is faster and
+supports LZF compression to speed it up further.

+for a 16 byte signature. That signature will be located on a 256-byte boundary.
+
+Signature:
+0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
+0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
+
+The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
+reserved for API calls. The second 10 are used by the firmware for event
+notification.
+
+  Index  Name
+  -----  ----
+  0      Flags
+  1      Command
+  2      Return value
+  3      Timeout
+  4-19   Parameter/Result
+
+
+The flags are defined in the following table. The direction is from the
+perspective of the firmware.
+
+  Bit  Direction  Purpose
+  ---  ---------  -------
+  2    O          Firmware has processed the command.
+  1    I          Driver has finished setting the parameters.
+  0    I          Driver is using this mailbox.
+
+
+The command is a 32-bit enumerator. The API specifics may be found in the
+fw-*-api.txt documents.
+
+The return value is a 32-bit enumerator. Only two values are currently defined:
+0=success and -1=command undefined.
+
+There are 16 parameters/results 32-bit fields. The driver populates these fields
+with values for all the parameters required by the call. The driver overwrites
+these fields with result values returned by the call. The API specifics may be
+found in the fw-*-api.txt documents.
+
+The timeout value protects the card from a hung driver thread. If the driver
+doesn't handle the completed call within the timeout specified, the firmware
+will reset that mailbox.
+
+To make an API call, the driver iterates over each mailbox looking for the
+first one available (bit 0 has been cleared). The driver sets that bit, fills
+in the command enumerator, the timeout value and any required parameters. The
+driver then sets the parameter ready bit (bit 1). The firmware scans the
+mailboxes for pending commands, processes them, sets the result code, populates
+the result value array with that call's return values and sets the call
+complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
+and clear all the flags. If the driver does not perform this task within the
+time set in the timeout register, the firmware will reset that mailbox.
+
+Event notifications are sent from the firmware to the host. The host tells the
+firmware which events it is interested in via an API call. That call tells the
+firmware which notification mailbox to use. The firmware signals the host via
+an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
+value and Timeout words are not used.

+This page describes the structures and procedures used by the cx2341x DMA
+engine.
+
+Introduction
+============
+
+The cx2341x PCI interface is busmaster capable. This means it has a DMA
+engine to efficiently transfer large volumes of data between the card and main
+memory without requiring help from a CPU. Like most hardware, it must operate
+on contiguous physical memory. This is difficult to come by in large quantities
+on virtual memory machines.
+
+Therefore, it also supports a technique called "scatter-gather". The card can
+transfer multiple buffers in one operation. Instead of allocating one large
+contiguous buffer, the driver can allocate several smaller buffers.
+
+In practice, I've seen the average transfer to be roughly 80K, but transfers
+above 128K were not uncommon, particularly at startup. The 128K figure is
+important, because that is the largest block that the kernel can normally
+allocate. Even still, 128K blocks are hard to come by, so the driver writer is
+urged to choose a smaller block size and learn the scatter-gather technique.
+
+Mailbox #10 is reserved for DMA transfer information.
+
+Flow
+====
+
+This section describes, in general, the order of events when handling DMA
+transfers. Detailed information follows this section.
+
+- The card raises the Encoder interrupt.
+- The driver reads the transfer type, offset and size from Mailbox #10.
+- The driver constructs the scatter-gather array from enough free dma buffers
+  to cover the size.
+- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
+- The card raises the DMA Complete interrupt.
+- The driver checks the DMA status register for any errors.
+- The driver post-processes the newly transferred buffers.
+
+NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
+simultaneously. (End of the last, start of the next, etc.)
+
+Mailbox #10
+===========
+
+The Flags, Command, Return Value and Timeout fields are ignored.
+
+Name:       Mailbox #10
+Results[0]: Type: 0: MPEG.
+Results[1]: Offset: The position relative to the card's memory space.
+Results[2]: Size: The exact number of bytes to transfer.
+
+My speculation is that since the StartCapture API has a capture type of "RAW"
+available, that the type field will have other values that correspond to YUV
+and PCM data.
+
+Scatter-Gather Array
+====================
+
+The scatter-gather array is a contiguously allocated block of memory that
+tells the card the source and destination of each data-block to transfer.
+Card "addresses" are derived from the offset supplied by Mailbox #10. Host
+addresses are the physical memory location of the target DMA buffer.
+
+Each S-G array element is a struct of three 32-bit words. The first word is
+the source address, the second is the destination address. Both take up the
+entire 32 bits. The lowest 16 bits of the third word is the transfer byte
+count. The high-bit of the third word is the "last" flag. The last-flag tells
+the card to raise the DMA_DONE interrupt. From hard personal experience, if
+you forget to set this bit, the card will still "work" but the stream will
+most likely get corrupted.
+
+The transfer count must be a multiple of 256. Therefore, the driver will need
+to track how much data in the target buffer is valid and deal with it
+accordingly.
+
+Array Element:
+
+- 32-bit Source Address
+- 32-bit Destination Address
+- 16-bit reserved (high bit is the last flag)
+- 16-bit byte count
+
+DMA Transfer Status
+===================
+
+Register 0x0004 holds the DMA Transfer Status:
+
+Bit
+4   Scatter-Gather array error
+3   DMA write error
+2   DMA read error
+1   write completed
+0   read completed

+This document describes the cx2341x memory map and documents some of the register
+space.
+
+Warning! This information was figured out from searching through the memory and
+registers, this information may not be correct and is certainly not complete, and
+was not derived from anything more than searching through the memory space with
+commands like:
+
+	ivtvctl -O min=0x02000000,max=0x020000ff
+
+So take this as is, I'm always searching for more stuff, it's a large
+register space :-).
+
+Memory Map
+==========
+
+The cx2341x exposes its entire 64M memory space to the PCI host via the PCI BAR0
+(Base Address Register 0). The addresses here are offsets relative to the
+address held in BAR0.
+
+0x00000000-0x00ffffff Encoder memory space
+0x00000000-0x0003ffff Encode.rom
+      ???-???         MPEG buffer(s)
+      ???-???         Raw video capture buffer(s)
+      ???-???         Raw audio capture buffer(s)
+      ???-???         Display buffers (6 or 9)
+

+0x0114b000-0x0115afff Audio.rom (deprecated?)
+
+0x02000000-0x0200ffff Register Space
+
+Registers
+=========
+
+The registers occupy the 64k space starting at the 0x02000000 offset from BAR0.
+All of these registers are 32 bits wide.
+
+DMA Registers 0x000-0xff:
+
+ 0x00 - Control:
+	0=reset/cancel, 1=read, 2=write, 4=stop
+ 0x04 - DMA status:
+	1=read busy, 2=write busy, 4=read error, 8=write error, 16=link list error
+ 0x08 - pci DMA pointer for read link list
+ 0x0c - pci DMA pointer for write link list
+ 0x10 - read/write DMA enable:
+	1=read enable, 2=write enable
+ 0x14 - always 0xffffffff, if set any lower instability occurs, 0x00 crashes
+ 0x18 - ??
+ 0x1c - always 0x20 or 32, smaller values slow down DMA transactions
+ 0x20 - always value of 0x780a010a
+ 0x24-0x3c - usually just random values???
+ 0x40 - Interrupt status
+ 0x44 - Write a bit here and shows up in Interrupt status 0x40
+ 0x48 - Interrupt Mask
+ 0x4C - always value of 0xfffdffff,
+	if changed to 0xffffffff DMA write interrupts break.
+ 0x50 - always 0xffffffff
+ 0x54 - always 0xffffffff (0x4c, 0x50, 0x54 seem like interrupt masks, are
+	3 processors on chip, Java ones, VPU, SPU, APU, maybe these are the
+	interrupt masks???).
+ 0x60-0x7C - random values
+ 0x80 - first write linked list reg, for Encoder Memory addr
+ 0x84 - first write linked list reg, for pci memory addr
+ 0x88 - first write linked list reg, for length of buffer in memory addr
+	(|0x80000000 or this for last link)
+ 0x8c-0xcc - rest of write linked list reg, 8 sets of 3 total, DMA goes here
+	from linked list addr in reg 0x0c, firmware must push through or
+	something.
+ 0xe0 - first (and only) read linked list reg, for pci memory addr
+ 0xe4 - first (and only) read linked list reg, for Decoder memory addr
+ 0xe8 - first (and only) read linked list reg, for length of buffer
+ 0xec-0xff - Nothing seems to be in these registers, 0xec-f4 are 0x00000000.
+
+Memory locations for Encoder Buffers 0x700-0x7ff:
+
+These registers show offsets of memory locations pertaining to each
+buffer area used for encoding, have to shift them by <<1 first.
+
+0x07F8: Encoder SDRAM refresh

+This document describes how to upload the cx2341x firmware to the card.
+
+How to find
+===========
+
+See the web pages of the various projects that uses this chip for information
+on how to obtain the firmware.
+
+The firmware stored in a Windows driver can be detected as follows:
+
+- Each firmware image is 256k bytes.
+- The 1st 32-bit word of the Encoder image is 0x0000da7
+- The 1st 32-bit word of the Decoder image is 0x00003a7
+- The 2nd 32-bit word of both images is 0xaa55bb66
+
+How to load
+===========
+
+- Issue the FWapi command to stop the encoder if it is running. Wait for the
+  command to complete.
+- Issue the FWapi command to stop the decoder if it is running. Wait for the
+  command to complete.
+- Issue the I2C command to the digitizer to stop emitting VSYNC events.
+- Issue the FWapi command to halt the encoder's firmware.
+- Sleep for 10ms.
+- Issue the FWapi command to halt the decoder's firmware.
+- Sleep for 10ms.
+- Write 0x00000000 to register 0x2800 to stop the Video Display Module.
+- Write 0x00000005 to register 0x2D00 to stop the AO (audio output?).
+- Write 0x00000000 to register 0xA064 to ping? the APU.
+- Write 0xFFFFFFFE to register 0x9058 to stop the VPU.
+- Write 0xFFFFFFFF to register 0x9054 to reset the HW blocks.
+- Write 0x00000001 to register 0x9050 to stop the SPU.
+- Sleep for 10ms.
+- Write 0x0000001A to register 0x07FC to init the Encoder SDRAM's pre-charge.
+- Write 0x80000640 to register 0x07F8 to init the Encoder SDRAM's refresh to 1us.
+- Write 0x0000001A to register 0x08FC to init the Decoder SDRAM's pre-charge.
+- Write 0x80000640 to register 0x08F8 to init the Decoder SDRAM's refresh to 1us.
+- Sleep for 512ms. (600ms is recommended)
+- Transfer the encoder's firmware image to offset 0 in Encoder memory space.
+- Transfer the decoder's firmware image to offset 0 in Decoder memory space.
+- Use a read-modify-write operation to Clear bit 0 of register 0x9050 to
+  re-enable the SPU.
+- Sleep for 1 second.
+- Use a read-modify-write operation to Clear bits 3 and 0 of register 0x9058
+  to re-enable the VPU.
+- Sleep for 1 second.
+- Issue status API commands to both firmware images to verify.

+
+>From the data sheet:
+ Register 24'h20004  PCI Interrupt Status
+  bit [18]  IR_SMP_INT Set when 32 input samples have been collected over
+  gpio[16] pin into GP_SAMPLE register.
+
+What's missing from the data sheet:
+
+Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
+compat remote)
+set register 0x35C050 to  0xa80a80
+
+enable sampling
+set register 0x35C054 to 0x5
+
+Of course, enable the IRQ bit 18 in the interrupt mask register .(and
+provide for a handler)
+
+GP_SAMPLE register is at 0x35C058
+
+Bits are then right shifted into the GP_SAMPLE register at the specified
+rate; you get an interrupt when a full DWORD is recieved.
+You need to recover the actual RC5 bits out of the (oversampled) IR sensor
+bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
+actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
+
+I'm pretty sure when no IR signal is present the receiver is always in a
+marking state(1); but stray light, etc can cause intermittent noise values
+as well.  Remember, this is a free running sample of the IR receiver state
+over time, so don't assume any sample starts at any particular place.
+
+http://www.atmel.com/dyn/resources/prod_documents/doc2817.pdf
+This data sheet (google search) seems to have a lovely description of the
+RC5 basics
+
+http://users.pandora.be/nenya/electronics/rc5/  and more data
+
+http://www.ee.washington.edu/circuit_archive/text/ir_decode.txt
+and even a reference to how to decode a bi-phase data stream.

 framerate       This setting controls frame rate of the camera. This is
-                an approximate setting (in terms of "worst" ... "best")
-                because camera changes frame rate depending on amount
-                of light available. Setting 0 is slowest, 6 is fastest.
-                Beware - fast settings are very demanding and may not
-                work well with all video sizes. Be conservative.

 hue_correction  This highly optional setting allows to adjust the
-                hue of the image in a way slightly different from
-                what usual "hue" control does. Both controls affect
-                YUV colorspace: regular "hue" control adjusts only
-                U component, and this "hue_correction" option similarly
-                adjusts only V component. However usually it is enough
-                to tweak only U or V to compensate for colored light or
-                color temperature; this option simply allows more
-                complicated correction when and if it is necessary.

 init_brightness These settings specify _initial_ values which will be
 init_contrast   used to set up the camera. If your V4L application has
 init_color      its own controls to adjust the picture then these
 init_hue        controls will be used too. These options allow you to

-TODO list
----------
-
-- Page migration requires the use of swap handles to preserve the
-  information of the anonymous page table entries. This means that swap
-  space is reserved but never used. The maximum number of swap handles used
-  is determined by CHUNK_SIZE (see mm/mempolicy.c) per ongoing migration.
-  Reservation of pages could be avoided by having a special type of swap
-  handle that does not require swap space and that would only track the page
-  references. Something like that was proposed by Marcelo Tosatti in the
-  past (search for migration cache on lkml or linux-mm@kvack.org).
-
-- Page migration unmaps ptes for file backed pages and requires page
-  faults to reestablish these ptes. This could be optimized by somehow
-  recording the references before migration and then reestablish them later.
-  However, there are several locking challenges that have to be overcome
-  before this is possible.
-
-- Page migration generates read ptes for anonymous pages. Dirty page
-  faults are required to make the pages writable again. It may be possible
-  to generate a pte marked dirty if it is known that the page is dirty and
-  that this process has the only reference to that page.

+Userspace communication protocol over connector [1].
+
+
+Message types.
+=============
+
+There are three types of messages between w1 core and userspace:
+1. Events. They are generated each time new master or slave device found
+	either due to automatic or requested search.
+2. Userspace commands. Includes read/write and search/alarm search comamnds.
+3. Replies to userspace commands.
+
+
+Protocol.
+========
+
+[struct cn_msg] - connector header. It's length field is equal to size of the attached data.
+[struct w1_netlink_msg] - w1 netlink header.
+	__u8 type 	- message type.
+			W1_SLAVE_ADD/W1_SLAVE_REMOVE - slave add/remove events.
+			W1_MASTER_ADD/W1_MASTER_REMOVE - master add/remove events.
+			W1_MASTER_CMD - userspace command for bus master device (search/alarm search).
+			W1_SLAVE_CMD - userspace command for slave device (read/write/ search/alarm search
+					for bus master device where given slave device found).
+	__u8 res	- reserved
+	__u16 len	- size of attached to this header data.
+	union {
+		__u8 id;			 - slave unique device id
+		struct w1_mst {
+			__u32		id;	 - master's id.
+			__u32		res;	 - reserved
+		} mst;
+	} id;
+
+[strucrt w1_netlink_cmd] - command for gived master or slave device.
+	__u8 cmd	- command opcode.
+			W1_CMD_READ 	- read command.
+			W1_CMD_WRITE	- write command.
+			W1_CMD_SEARCH	- search command.
+			W1_CMD_ALARM_SEARCH - alarm search command.
+	__u8 res	- reserved
+	__u16 len	- length of data for this command.
+			For read command data must be allocated like for write command.
+	__u8 data[0]	- data for this command.
+
+
+Each connector message can include one or more w1_netlink_msg with zero of more attached w1_netlink_cmd messages.
+
+For event messages there are no w1_netlink_cmd embedded structures, only connector header
+and w1_netlink_msg strucutre with "len" field being zero and filled type (one of event types)
+and id - either 8 bytes of slave unique id in host order, or master's id, which is assigned
+to bus master device when it is added to w1 core.
+
+Currently replies to userspace commands are only generated for read command request.
+One reply is generated exactly for one w1_netlink_cmd read request.
+Replies are not combined when sent - i.e. typical reply messages looks like the following:
+[cn_msg][w1_netlink_msg][w1_netlink_cmd]
+cn_msg.len = sizeof(struct w1_netlink_msg) + sizeof(struct w1_netlink_cmd) + cmd->len;
+w1_netlink_msg.len = sizeof(struct w1_netlink_cmd) + cmd->len;
+w1_netlink_cmd.len = cmd->len;
+
+
+Operation steps in w1 core when new command is received.
+=======================================================
+
+When new message (w1_netlink_msg) is received w1 core detects if it is master of slave request,
+according to w1_netlink_msg.type field.
+Then master or slave device is searched for.
+When found, master device (requested or those one on where slave device is found) is locked.
+If slave command is requested, then reset/select procedure is started to select given device.
+
+Then all requested in w1_netlink_msg operations are performed one by one.
+If command requires reply (like read command) it is sent on command completion.
+
+When all commands (w1_netlink_cmd) are processed muster device is unlocked
+and next w1_netlink_msg header processing started.
+
+
+Connector [1] specific documentation.
+====================================
+
+Each connector message includes two u32 fields as "address".
+w1 uses CN_W1_IDX and CN_W1_VAL defined in include/linux/connector.h header.
+Each message also includes sequence and acknowledge numbers.
+Sequence number for event messages is appropriate bus master sequence number increased with
+each event message sent "through" this master.
+Sequence number for userspace requests is set by userspace application.
+Sequence number for reply is the same as was in request, and
+acknowledge number is set to seq+1.

+ * Horrid, horrid, horrid.
+ *
+ * It turns out that the _only_ piece of hardware that actually
+ * keeps its value across a hard boot (and, more importantly, the
+ * POST init sequence) is literally the realtime clock.
+ *
+ * Never mind that an RTC chip has 114 bytes (and often a whole
+ * other bank of an additional 128 bytes) of nice SRAM that is
+ * _designed_ to keep data - the POST will clear it. So we literally
+ * can just use the few bytes of actual time data, which means that
+ * we're really limited.
+ *
+ * It means, for example, that we can't use the seconds at all
+ * (since the time between the hang and the boot might be more
+ * than a minute), and we'd better not depend on the low bits of
+ * the minutes either.
+ *
+ * There are the wday fields etc, but I wouldn't guarantee those
+ * are dependable either. And if the date isn't valid, either the
+ * hw or POST will do strange things.
+ *
+ * So we're left with:
+ *  - year: 0-99
+ *  - month: 0-11
+ *  - day-of-month: 1-28
+ *  - hour: 0-23
+ *  - min: (0-30)*2
+ *
+ * Giving us a total range of 0-16128000 (0xf61800), ie less
+ * than 24 bits of actual data we can save across reboots.
+ *
+ * And if your box can't boot in less than three minutes,
+ * you're screwed.
+ *
+ * Now, almost 24 bits of data is pitifully small, so we need
+ * to be pretty dense if we want to use it for anything nice.
+ * What we do is that instead of saving off nice readable info,
+ * we save off _hashes_ of information that we can hopefully
+ * regenerate after the reboot.
+ *
+ * In particular, this means that we might be unlucky, and hit
+ * a case where we have a hash collision, and we end up not
+ * being able to tell for certain exactly which case happened.
+ * But that's hopefully unlikely.
+ *
+ * What we do is to take the bits we can fit, and split them
+ * into three parts (16*997*1009 = 16095568), and use the values
+ * for:
+ *  - 0-15: user-settable
+ *  - 0-996: file + line number
+ *  - 0-1008: device

+ * During I2C reads, the KS0127 only samples for a stop condition
+ * during the place where the acknoledge bit should be. Any standard

+ * at the 9th bit, and the KS0127 will not recognize the stop condition
+ * and will continue to clock out data.

+ * We have two different locks in the bcm43xx driver.

+ *                   and the device registers.
+ * => bcm->irq_lock: IRQ spinlock. Protects against IRQ handler concurrency.
+ *
+ * We have three types of helper function pairs to utilize these locks.
+ *     (Always use the helper functions.)
+ * 1) bcm43xx_{un}lock_noirq():
+ *     Takes bcm->mutex. Does _not_ protect against IRQ concurrency,
+ *     so it is almost always unsafe, if device IRQs are enabled.
+ *     So only use this, if device IRQs are masked.
+ *     Locking may sleep.
+ *     You can sleep within the critical section.
+ * 2) bcm43xx_{un}lock_irqonly():
+ *     Takes bcm->irq_lock. Does _not_ protect against
+ *     bcm43xx_lock_noirq() critical sections.
+ *     Does only protect against the IRQ handler path and other
+ *     irqonly() critical sections.
+ *     Locking does not sleep.
+ *     You must not sleep within the critical section.
+ * 3) bcm43xx_{un}lock_irqsafe():
+ *     This is the cummulative lock and takes both, mutex and irq_lock.
+ *     Protects against noirq() and irqonly() critical sections (and
+ *     the IRQ handler path).
+ *     Locking may sleep.
+ *     You must not sleep within the critical section.

 /*
- * Unfortunately request interruption not just solves the deadlock
- * problem, it causes problems too.  These stem from the fact, that an
- * interrupted request is continued to be processed in userspace,
- * while all the locks and object references (inode and file) held
- * during the operation are released.
- *
- * To release the locks is exactly why there's a need to interrupt the
- * request, so there's not a lot that can be done about this, except
- * introduce additional locking in userspace.
- *
- * More important is to keep inode and file references until userspace
- * has replied, otherwise FORGET and RELEASE could be sent while the
- * inode/file is still used by the filesystem.
- *
- * For this reason the concept of "background" request is introduced.
- * An interrupted request is backgrounded if it has been already sent
- * to userspace.  Backgrounding involves getting an extra reference to
- * inode(s) or file used in the request, and adding the request to
- * fc->background list.  When a reply is received for a background
- * request, the object references are released, and the request is
- * removed from the list.  If the filesystem is unmounted while there
- * are still background requests, the list is walked and references
- * are released as if a reply was received.
+ * This function is called when a request is finished.  Either a reply
+ * has arrived or it was aborted (and not yet sent) or some error
+ * occurred during communication with userspace, or the device file
+ * was closed.  The requester thread is woken up (if still waiting),
+ * the 'end' callback is called if given, else the reference to the
+ * request is released
  *
- * There's one more use for a background request.  The RELEASE message is
- * always sent as background, since it doesn't return an error or
- * data.
+ * Called with fc->lock, unlocks it

+ * %__GFP_NOFAIL - Indicate that this allocation is in no way allowed to fail
+ *   (think twice before using).
+ *
+ * %__GFP_NORETRY - If memory is not immediately available,

+ * %__GFP_NOWARN - If allocation fails, don't issue any warnings.

+  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped

+
      The library also supports reading and writing files in gzip (.gz) format
   with an interface similar to that of stdio.
 
+     The zlib format was designed to be compact and fast for use in memory

+  file compression on file systems, has a larger header than zlib to maintain
+  directory information, and uses a different, slower check method than zlib.

      The library does not install any signal handler. The decoder checks
   the consistency of the compressed data, so the library should never
   crash even in case of corrupted input.

-    If the parameter flush is set to Z_SYNC_FLUSH, inflate flushes as much
-  output as possible to the output buffer. The flushing behavior of inflate is
-  not specified for values of the flush parameter other than Z_SYNC_FLUSH
-  and Z_FINISH, but the current implementation actually flushes as much output
-  as possible anyway.
+    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH,
+  Z_FINISH, or Z_BLOCK. Z_SYNC_FLUSH requests that inflate() flush as much
+  output as possible to the output buffer. Z_BLOCK requests that inflate() stop
+  if and when it gets to the next deflate block boundary. When decoding the
+  zlib or gzip format, this will cause inflate() to return immediately after
+  the header and before the first block. When doing a raw inflate, inflate()
+  will go ahead and process the first block, and will return when it gets to
+  the end of that block, or when it runs out of data.
+
+    The Z_BLOCK option assists in appending to or combining deflate streams.
+  Also to assist in this, on return inflate() will set strm->data_type to the
+  number of unused bits in the last byte taken from strm->next_in, plus 64
+  if inflate() is currently decoding the last block in the deflate stream,
+  plus 128 if inflate() returned immediately after decoding an end-of-block
+  code or decoding the complete header up to just before the first byte of the
+  deflate stream. The end-of-block will not be indicated until all of the
+  uncompressed data from that block has been written to strm->next_out.  The
+  number of unused bits may in general be greater than seven, except when
+  bit 7 of data_type is set, in which case the number of unused bits will be

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= 6
+        strm->avail_out >= 258
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
+        break;
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

 /*
-   Huffman code decoding is performed using a multi-level table lookup.
-   The fastest way to decode is to simply build a lookup table whose
-   size is determined by the longest code.  However, the time it takes
-   to build this table can also be a factor if the data being decoded
-   is not very long.  The most common codes are necessarily the
-   shortest codes, so those codes dominate the decoding time, and hence
-   the speed.  The idea is you can have a shorter table that decodes the
-   shorter, more probable codes, and then point to subsidiary tables for
-   the longer codes.  The time it costs to decode the longer codes is
-   then traded against the time it takes to make longer tables.
-
-   This results of this trade are in the variables lbits and dbits
-   below.  lbits is the number of bits the first level table for literal/
-   length codes can decode in one step, and dbits is the same thing for
-   the distance codes.  Subsequent tables are also less than or equal to
-   those sizes.  These values may be adjusted either when all of the
-   codes are shorter than that, in which case the longest code length in
-   bits is used, or when the shortest code is *longer* than the requested
-   table size, in which case the length of the shortest code in bits is
-   used.
-
-   There are two different values for the two tables, since they code a
-   different number of possibilities each.  The literal/length table
-   codes 286 possible values, or in a flat code, a little over eight
-   bits.  The distance table codes 30 possible values, or a little less
-   than five bits, flat.  The optimum values for speed end up being
-   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-   The optimum values may differ though from machine to machine, and
-   possibly even between compilers.  Your mileage may vary.
+   Build a set of tables to decode the provided canonical Huffman code.
+   The code lengths are lens[0..codes-1].  The result starts at *table,
+   whose indices are 0..2^bits-1.  work is a writable array of at least
+   lens shorts, which is used as a work area.  type is the type of code
+   to be generated, CODES, LENS, or DISTS.  On return, zero is success,
+   -1 is an invalid code, and +1 means that ENOUGH isn't enough.  table
+   on return points to the next available entry's address.  bits is the
+   requested root table index bits, and on return it is the actual root
+   table index bits.  It will differ if the request is greater than the
+   longest code or if it is less than the shortest code.

+       creating from that a table of starting indices for each length in the
+       sorted table, and then entering the symbols in order in the sorted
+       table.  The sorted table is work[], with that space being provided by
+       the caller.
+
+       The length counts are used for other purposes as well, i.e. finding
+       the minimum and maximum length codes, determining if there are any
+       codes at all, checking for a valid set of lengths, and looking ahead
+       at length counts to determine sub-table sizes when building the
+       decoding tables.

+       Create and fill in decoding tables.  In this loop, the table being
+       filled is at next and has curr index bits.  The code being used is huff
+       with length len.  That code is converted to an index by dropping drop
+       bits off of the bottom.  For codes where len is less than drop + curr,
+       those top drop + curr - len bits are incremented through all values to
+       fill the table with replicated entries.
+
+       root is the number of index bits for the root table.  When len exceeds
+       root, sub-tables are created pointed to by the root entry with an index
+       of the low root bits of huff.  This is saved in low to check for when a
+       new sub-table should be started.  drop is zero when the root table is
+       being filled, and drop is root when sub-tables are being filled.
+
+       When a new sub-table is needed, it is necessary to look ahead in the
+       code lengths to determine what size sub-table is needed.  The length
+       counts are used for this, and so count[] is decremented as codes are
+       entered in the tables.
+
+       used keeps track of how many table entries have been allocated from the
+       provided *table space.  It is checked when a LENS table is being made
+       against the space in *table, ENOUGH, minus the maximum space needed by
+       the worst case distance code, MAXD.  This should never happen, but the
+       sufficiency of ENOUGH has not been proven exhaustively, hence the check.
+       This assumes that when type == LENS, bits == 9.
+
+       sym increments through all symbols, and the loop terminates when
+       all codes of length max, i.e. all codes, have been processed.  This
+       routine permits incomplete codes, so another loop after this one fills
+       in the rest of the decoding tables with invalid code markers.

+ *
+ *
+ * This is a driver for the pcm3052 codec chip (codenamed Onyx)
+ * that is present in newer Apple hardware (with digital output).
+ *
+ * The Onyx codec has the following connections (listed by the bit
+ * to be used in aoa_codec.connected):
+ *  0: analog output
+ *  1: digital output
+ *  2: line input
+ *  3: microphone input
+ * Note that even though I know of no machine that has for example
+ * the digital output connected but not the analog, I have handled
+ * all the different cases in the code so that this driver may serve
+ * as a good example of what to do.
+ *
+ * NOTE: This driver assumes that there's at most one chip to be
+ * 	 used with one alsa card, in form of creating all kinds
+ *	 of mixer elements without regard for their existence.
+ *	 But snd-aoa assumes that there's at most one card, so
+ *	 this means you can only have one onyx on a system. This
+ *	 should probably be fixed by changing the assumption of
+ *	 having just a single card on a system, and making the
+ *	 'card' pointer accessible to anyone who needs it instead
+ *	 of hiding it in the aoa_snd_* functions...

+/*
+ * Apple Onboard Audio driver for tas codec
+ *
+ * Copyright 2006 Johannes Berg <johannes@sipsolutions.net>
+ *
+ * GPL v2, can be found in COPYING.
+ *
+ * Open questions:
+ *  - How to distinguish between 3004 and versions?
+ *
+ * FIXMEs:
+ *  - This codec driver doesn't honour the 'connected'
+ *    property of the aoa_codec struct, hence if
+ *    it is used in machines where not everything is
+ *    connected it will display wrong mixer elements.
+ *  - Driver assumes that the microphone is always
+ *    monaureal and connected to the right channel of
+ *    the input. This should also be a codec-dependent
+ *    flag, maybe the codec should have 3 different
+ *    bits for the three different possibilities how
+ *    it can be hooked up...
+ *    But as long as I don't see any hardware hooked
+ *    up that way...
+ *  - As Apple notes in their code, the tas3004 seems
+ *    to delay the right channel by one sample. You can
+ *    see this when for example recording stereo in
+ *    audacity, or recording the tas output via cable
+ *    on another machine (use a sinus generator or so).
+ *    I tried programming the BiQuads but couldn't
+ *    make the delay work, maybe someone can read the
+ *    datasheet and fix it. The relevant Apple comment
+ *    is in AppleTAS3004Audio.cpp lines 1637 ff. Note
+ *    that their comment describing how they program
+ *    the filters sucks...
+ *
+ * Other things:
+ *  - this should actually register *two* aoa_codec
+ *    structs since it has two inputs. Then it must
+ *    use the prepare callback to forbid running the
+ *    secondary output on a different clock.
+ *    Also, whatever bus knows how to do this must
+ *    provide two soundbus_dev devices and the fabric
+ *    must be able to link them correctly.
+ *
+ *    I don't even know if Apple ever uses the second
+ *    port on the tas3004 though, I don't think their
+ *    i2s controllers can even do it. OTOH, they all
+ *    derive the clocks from common clocks, so it
+ *    might just be possible. The framework allows the
+ *    codec to refine the transfer_info items in the
+ *    usable callback, so we can simply remove the
+ *    rates the second instance is not using when it
+ *    actually is in use.
+ *    Maybe we'll need to make the sound busses have
+ *    a 'clock group id' value so the codec can
+ *    determine if the two outputs can be driven at
+ *    the same time. But that is likely overkill, up
+ *    to the fabric to not link them up incorrectly,
+ *    and up to the hardware designer to not wire
+ *    them up in some weird unusable way.
