Part Ib - Using small dma-coherent buffers
Many drivers need lots of small dma-coherent memory regions for DMA

+Macintosh HFSPlus Filesystem for Linux
+======================================
+
+HFSPlus is a filesystem first introduced in MacOS 8.1.
+HFSPlus has several extensions to HFS, including 32-bit allocation
+blocks, 255-character unicode filenames, and file sizes of 2^63 bytes.
+
+
+Mount options
+=============
+
+When mounting an HFSPlus filesystem, the following options are accepted:
+
+ creator=cccc, type=cccc
+ Specifies the creator/type values as shown by the MacOS finder
+ used for creating new files. Default values: '????'.
+
+ uid=n, gid=n
+ Specifies the user/group that owns all files on the filesystem
+ that have uninitialized permissions structures.
+ Default: user/group id of the mounting process.
+
+ umask=n
+ Specifies the umask (in octal) used for files and directories
+ that have uninitialized permissions structures.
+ Default: umask of the mounting process.
+
+ session=n
+ Select the CDROM session to mount as HFSPlus filesystem. Defaults to
+ leaving that decision to the CDROM driver. This option will fail
+ with anything but a CDROM as underlying devices.
+
+ part=n
+ Select partition number n from the devices. This option only makes
+ sense for CDROMs because they can't be partitioned under Linux.
+ For disk devices the generic partition parsing code does this
+ for us. Defaults to not parsing the partition table at all.
+
+ decompose
+ Decompose file name characters.

+-----------------
+
+* adm1022_temp3: short array
+ List of adapter,address pairs to force chips into ADM1022 mode with
+ second remote temperature. This does not work for original THMC50 chips.
+
+Description
+-----------
+
+The THMC50 implements: an internal temperature sensor, support for an
+external diode-type temperature sensor (compatible w/ the diode sensor inside
+many processors), and a controllable fan/analog_out DAC. For the temperature
+sensors, limits can be set through the appropriate Overtemperature Shutdown
+register and Hysteresis register. Each value can be set and read to half-degree
+accuracy. An alarm is issued (usually to a connected LM78) when the
+temperature gets higher then the Overtemperature Shutdown value; it stays on
+until the temperature falls below the Hysteresis value. All temperatures are in
+degrees Celsius, and are guaranteed within a range of -55 to +125 degrees.
+
+The THMC50 only updates its values each 1.5 seconds; reading it more often
+will do no harm, but will return 'old' values.
+
+The THMC50 is usually used in combination with LM78-like chips, to measure
+the temperature of the processor(s).
+
+The ADM1022 works the same as THMC50 but it is faster (5 Hz instead of
+1 Hz for THMC50). It can be also put in a new mode to handle additional
+remote temperature sensor. The driver use the mode set by BIOS by default.
+
+In case the BIOS is broken and the mode is set incorrectly, you can force
+the mode with additional remote temperature with adm1022_temp3 parameter.
+A typical symptom of wrong setting is a fan forced to full speed.
+
+Driver Features
+---------------
+
+The driver provides up to three temperatures:
+
+temp1 -- internal
+temp2 -- remote
+temp3 -- 2nd remote only for ADM1022
+
+pwm1 -- fan speed (0 = stop, 255 = full)
+pwm1_mode -- always 0 (DC mode)
+
+The value of 0 for pwm1 also forces FAN_OFF signal from the chip,
+so it stops fans even if the value 0 into the ANALOG_OUT register does not.
+
+The driver was tested on Compaq AP550 with two ADM1022 chips (one works
+in the temp3 mode), five temperature readings and two fans.

-4. subsystems
-
-4.1 Description
-
-A subsystem represents a significant entity of code that maintains an
-arbitrary number of sets of objects of various types. Since the number
-of ksets and the type of objects they contain are variable, a
-generic representation of a subsystem is minimal.
-
-
-struct subsystem {
- struct kset kset;
- struct rw_semaphore rwsem;
-};
-
-int subsystem_register(struct subsystem *);
-void subsystem_unregister(struct subsystem *);
-
-struct subsystem * subsys_get(struct subsystem * s);
-void subsys_put(struct subsystem * s);
-
-
-A subsystem contains an embedded kset so:
-
-- It can be represented in the object hierarchy via the kset's
- embedded kobject.
-
-- It can maintain a default list of objects of one type.
-
-Additional ksets may attach to the subsystem simply by referencing the
-subsystem before they are registered. (This one-way reference means
-that there is no way to determine the ksets that are attached to the
-subsystem.)
-
-All ksets that are attached to a subsystem share the subsystem's R/W
-semaphore.
-
-
-4.2 subsystem Programming Interface.
-
-The subsystem programming interface is simple and does not offer the
-flexibility that the kset and kobject programming interfaces do. They
-may be registered and unregistered, as well as reference counted. Each
-call forwards the calls to their embedded ksets (which forward the
-calls to their embedded kobjects).
-
-
-4.3 Helpers
-
-A number of macros are available to make dealing with subsystems and
-their embedded objects easier.
-
-
-decl_subsys(name,type)
-
-Declares a subsystem named '<name>_subsys', with an embedded kset of
-type <type>. For example,
-
-decl_subsys(devices,&ktype_devices);
-
-is equivalent to doing:
-
-struct subsystem device_subsys = {
- .kset = {
- .kobj = {
- .name = "devices",
- },
- .ktype = &ktype_devices,
- }
-};
-
-
-The objects that are registered with a subsystem that use the
-subsystem's default list must have their kset ptr set properly. These
-objects may have embedded kobjects, ksets, or other subsystems. The
-following helpers make setting the kset easier:
-
-
-kobj_set_kset_s(obj,subsys)
-
-- Assumes that obj->kobj exists, and is a struct kobject.
-- Sets the kset of that kobject to the subsystem's embedded kset.
-
-
-kset_set_kset_s(obj,subsys)
-
-- Assumes that obj->kset exists, and is a struct kset.
-- Sets the kset of the embedded kobject to the subsystem's
- embedded kset.
-
-subsys_set_kset(obj,subsys)
-
-- Assumes obj->subsys exists, and is a struct subsystem.
-- Sets obj->subsys.kset.kobj.kset to the subsystem's embedded kset.
-
-
-4.4 sysfs
-
-subsystems are represented in sysfs via their embedded kobjects. They
-follow the same rules as previously mentioned with no exceptions. They
-typically receive a top-level directory in sysfs, except when their
-embedded kobject is part of another kset, or the parent of the
-embedded kobject is explicitly set.
-
-Note that the subsystem's embedded kset must be 'attached' to the
-subsystem itself in order to use its rwsem. This is done after
-kset_add() has been called. (Not before, because kset_add() uses its
-subsystem for a default parent if it doesn't already have one).

+8. Future Work List
+
+Note(1): x86_64's has special implementation for memory hotplug.
+ This text does not describe it.
+Note(2): This text assumes that sysfs is mounted at /sys.
+
+
+---------------
+1. Introduction
+---------------
+
+1.1 purpose of memory hotplug
+------------
+Memory Hotplug allows users to increase/decrease the amount of memory.
+Generally, there are two purposes.
+
+(A) For changing the amount of memory.
+ This is to allow a feature like capacity on demand.
+(B) For installing/removing DIMMs or NUMA-nodes physically.
+ This is to exchange DIMMs/NUMA-nodes, reduce power consumption, etc.
+
+(A) is required by highly virtualized environments and (B) is required by
+hardware which supports memory power management.
+
+Linux memory hotplug is designed for both purpose.
+
+
+1.2. Phases of memory hotplug
+---------------
+There are 2 phases in Memory Hotplug.
+ 1) Physical Memory Hotplug phase
+ 2) Logical Memory Hotplug phase.
+
+The First phase is to communicate hardware/firmware and make/erase
+environment for hotplugged memory. Basically, this phase is necessary
+for the purpose (B), but this is good phase for communication between
+highly virtualized environments too.
+
+When memory is hotplugged, the kernel recognizes new memory, makes new memory
+management tables, and makes sysfs files for new memory's operation.
+
+If firmware supports notification of connection of new memory to OS,
+this phase is triggered automatically. ACPI can notify this event. If not,
+"probe" operation by system administration is used instead.
+(see Section 4.).
+
+Logical Memory Hotplug phase is to change memory state into
+avaiable/unavailable for users. Amount of memory from user's view is
+changed by this phase. The kernel makes all memory in it as free pages
+when a memory range is available.
+
+In this document, this phase is described as online/offline.
+
+Logical Memory Hotplug phase is triggred by write of sysfs file by system
+administrator. For the hot-add case, it must be executed after Physical Hotplug
+phase by hand.
+(However, if you writes udev's hotplug scripts for memory hotplug, these
+ phases can be execute in seamless way.)
+
+
+1.3. Unit of Memory online/offline operation
+------------
+Memory hotplug uses SPARSEMEM memory model. SPARSEMEM divides the whole memory
+into chunks of the same size. The chunk is called a "section". The size of
+a section is architecture dependent. For example, power uses 16MiB, ia64 uses
+1GiB. The unit of online/offline operation is "one section". (see Section 3.)
+
+To determine the size of sections, please read this file:
+
+/sys/devices/system/memory/block_size_bytes
+
+This file shows the size of sections in byte.
+
+-----------------------
+2. Kernel Configuration
+-----------------------
+To use memory hotplug feature, kernel must be compiled with following
+config options.
+
+- For all memory hotplug
+ Memory model -> Sparse Memory (CONFIG_SPARSEMEM)
+ Allow for memory hot-add (CONFIG_MEMORY_HOTPLUG)
+
+- To enable memory removal, the followings are also necessary
+ Allow for memory hot remove (CONFIG_MEMORY_HOTREMOVE)
+ Page Migration (CONFIG_MIGRATION)
+
+- For ACPI memory hotplug, the followings are also necessary
+ Memory hotplug (under ACPI Support menu) (CONFIG_ACPI_HOTPLUG_MEMORY)
+ This option can be kernel module.
+
+- As a related configuration, if your box has a feature of NUMA-node hotplug
+ via ACPI, then this option is necessary too.
+ ACPI0004,PNP0A05 and PNP0A06 Container Driver (under ACPI Support menu)
+ (CONFIG_ACPI_CONTAINER).
+ This option can be kernel module too.
+
+--------------------------------
+3 sysfs files for memory hotplug
+--------------------------------
+All sections have their device information under /sys/devices/system/memory as
+
+/sys/devices/system/memory/memoryXXX
+(XXX is section id.)
+
+Now, XXX is defined as start_address_of_section / section_size.
+
+For example, assume 1GiB section size. A device for a memory starting at
+0x100000000 is /sys/device/system/memory/memory4
+(0x100000000 / 1Gib = 4)
+This device covers address range [0x100000000 ... 0x140000000)
+
+Under each section, you can see 3 files.
+
+/sys/devices/system/memory/memoryXXX/phys_index
+/sys/devices/system/memory/memoryXXX/phys_device
+/sys/devices/system/memory/memoryXXX/state
+
+'phys_index' : read-only and contains section id, same as XXX.
+'state' : read-write
+ at read: contains online/offline state of memory.
+ at write: user can specify "online", "offline" command
+'phys_device': read-only: designed to show the name of physical memory device.
+ This is not well implemented now.
+
+NOTE:
+ These directories/files appear after physical memory hotplug phase.
+
+
+--------------------------------
+4. Physical memory hot-add phase
+--------------------------------
+
+4.1 Hardware(Firmware) Support
+------------
+On x86_64/ia64 platform, memory hotplug by ACPI is supported.
+
+In general, the firmware (ACPI) which supports memory hotplug defines
+memory class object of _HID "PNP0C80". When a notify is asserted to PNP0C80,
+Linux's ACPI handler does hot-add memory to the system and calls a hotplug udev
+script. This will be done automatically.
+
+But scripts for memory hotplug are not contained in generic udev package(now).
+You may have to write it by yourself or online/offline memory by hand.
+Please see "How to online memory", "How to offline memory" in this text.
+
+If firmware supports NUMA-node hotplug, and defines an object _HID "ACPI0004",
+"PNP0A05", or "PNP0A06", notification is asserted to it, and ACPI handler
+calls hotplug code for all of objects which are defined in it.
+If memory device is found, memory hotplug code will be called.
+
+
+4.2 Notify memory hot-add event by hand
+------------
+In some environments, especially virtualized environment, firmware will not
+notify memory hotplug event to the kernel. For such environment, "probe"
+interface is supported. This interface depends on CONFIG_ARCH_MEMORY_PROBE.
+
+Now, CONFIG_ARCH_MEMORY_PROBE is supported only by powerpc but it does not
+contain highly architecture codes. Please add config if you need "probe"
+interface.
+
+Probe interface is located at
+/sys/devices/system/memory/probe
+
+You can tell the physical address of new memory to the kernel by
+
+% echo start_address_of_new_memory > /sys/devices/system/memory/probe
+
+Then, [start_address_of_new_memory, start_address_of_new_memory + section_size)
+memory range is hot-added. In this case, hotplug script is not called (in
+current implementation). You'll have to online memory by yourself.
+Please see "How to online memory" in this text.
+
+
+
+------------------------------
+5. Logical Memory hot-add phase
+------------------------------
+
+5.1. State of memory
+------------
+To see (online/offline) state of memory section, read 'state' file.
+
+% cat /sys/device/system/memory/memoryXXX/state
+
+
+If the memory section is online, you'll read "online".
+If the memory section is offline, you'll read "offline".
+
+
+5.2. How to online memory
+------------
+Even if the memory is hot-added, it is not at ready-to-use state.
+For using newly added memory, you have to "online" the memory section.
+
+For onlining, you have to write "online" to the section's state file as:
+
+% echo online > /sys/devices/system/memory/memoryXXX/state
+
+After this, section memoryXXX's state will be 'online' and the amount of
+available memory will be increased.
+
+Currently, newly added memory is added as ZONE_NORMAL (for powerpc, ZONE_DMA).
+This may be changed in future.
+
+
+
+------------------------
+6. Logical memory remove
+------------------------
+
+6.1 Memory offline and ZONE_MOVABLE
+------------
+Memory offlining is more complicated than memory online. Because memory offline
+has to make the whole memory section be unused, memory offline can fail if
+the section includes memory which cannot be freed.
+
+In general, memory offline can use 2 techniques.
+
+(1) reclaim and free all memory in the section.
+(2) migrate all pages in the section.
+
+In the current implementation, Linux's memory offline uses method (2), freeing
+all pages in the section by page migration. But not all pages are
+migratable. Under current Linux, migratable pages are anonymous pages and
+page caches. For offlining a section by migration, the kernel has to guarantee
+that the section contains only migratable pages.
+
+Now, a boot option for making a section which consists of migratable pages is
+supported. By specifying "kernelcore=" or "movablecore=" boot option, you can
+create ZONE_MOVABLE...a zone which is just used for movable pages.
+(See also Documentation/kernel-parameters.txt)
+
+Assume the system has "TOTAL" amount of memory at boot time, this boot option
+creates ZONE_MOVABLE as following.
+
+1) When kernelcore=YYYY boot option is used,
+ Size of memory not for movable pages (not for offline) is YYYY.
+ Size of memory for movable pages (for offline) is TOTAL-YYYY.
+
+2) When movablecore=ZZZZ boot option is used,
+ Size of memory not for movable pages (not for offline) is TOTAL - ZZZZ.
+ Size of memory for movable pages (for offline) is ZZZZ.
+
+
+Note) Unfortunately, there is no information to show which section belongs
+to ZONE_MOVABLE. This is TBD.
+
+
+6.2. How to offline memory
+------------
+You can offline a section by using the same sysfs interface that was used in
+memory onlining.
+
+% echo offline > /sys/devices/system/memory/memoryXXX/state
+
+If offline succeeds, the state of the memory section is changed to be "offline".
+If it fails, some error core (like -EBUSY) will be returned by the kernel.
+Even if a section does not belong to ZONE_MOVABLE, you can try to offline it.
+If it doesn't contain 'unmovable' memory, you'll get success.
+
+A section under ZONE_MOVABLE is considered to be able to be offlined easily.
+But under some busy state, it may return -EBUSY. Even if a memory section
+cannot be offlined due to -EBUSY, you can retry offlining it and may be able to
+offline it (or not).
+(For example, a page is referred to by some kernel internal call and released
+ soon.)
+
+Consideration:
+Memory hotplug's design direction is to make the possibility of memory offlining
+higher and to guarantee unplugging memory under any situation. But it needs
+more work. Returning -EBUSY under some situation may be good because the user
+can decide to retry more or not by himself. Currently, memory offlining code
+does some amount of retry with 120 seconds timeout.
+
+-------------------------
+7. Physical memory remove
+-------------------------
+Need more implementation yet....
+ - Notification completion of remove works by OS to firmware.
+ - Guard from remove if not yet.
+
+--------------
+8. Future Work
+--------------
+ - allowing memory hot-add to ZONE_MOVABLE. maybe we need some switch like
+ sysctl or new control file.
+ - showing memory section and physical device relationship.
+ - showing memory section and node relationship (maybe good for NUMA)
+ - showing memory section is under ZONE_MOVABLE or not
+ - test and make it better memory offlining.
+ - support HugeTLB page migration and offlining.
+ - memmap removing at memory offline.
+ - physical remove memory.
+
CFS uses nanosecond granularity accounting and does not rely on any
jiffies or other HZ detail. Thus the CFS scheduler has no notion of
'timeslices' and has no heuristics whatsoever. There is only one
- central tunable:
+ central tunable (you have to switch on CONFIG_SCHED_DEBUG):
/proc/sys/kernel/sched_granularity_ns
--- /dev/null
+This document explains the thinking about the revamped and streamlined
+nice-levels implementation in the new Linux scheduler.
+
+Nice levels were always pretty weak under Linux and people continuously
+pestered us to make nice +19 tasks use up much less CPU time.
+
+Unfortunately that was not that easy to implement under the old
+scheduler, (otherwise we'd have done it long ago) because nice level
+support was historically coupled to timeslice length, and timeslice
+units were driven by the HZ tick, so the smallest timeslice was 1/HZ.
+
+In the O(1) scheduler (in 2003) we changed negative nice levels to be
+much stronger than they were before in 2.4 (and people were happy about
+that change), and we also intentionally calibrated the linear timeslice
+rule so that nice +19 level would be _exactly_ 1 jiffy. To better
+understand it, the timeslice graph went like this (cheesy ASCII art
+alert!):
+
+
+ A
+ \ | [timeslice length]
+ \ |
+ \ |
+ \ |
+ \ |
+ \|___100msecs
+ |^ . _
+ | ^ . _
+ | ^ . _
+ -*----------------------------------*-----> [nice level]
+ -20 | +19
+ |
+ |
+
+So that if someone wanted to really renice tasks, +19 would give a much
+bigger hit than the normal linear rule would do. (The solution of
+changing the ABI to extend priorities was discarded early on.)
+
+This approach worked to some degree for some time, but later on with
+HZ=1000 it caused 1 jiffy to be 1 msec, which meant 0.1% CPU usage which
+we felt to be a bit excessive. Excessive _not_ because it's too small of
+a CPU utilization, but because it causes too frequent (once per
+millisec) rescheduling. (and would thus trash the cache, etc. Remember,
+this was long ago when hardware was weaker and caches were smaller, and
+people were running number crunching apps at nice +19.)
+
+So for HZ=1000 we changed nice +19 to 5msecs, because that felt like the
+right minimal granularity - and this translates to 5% CPU utilization.
+But the fundamental HZ-sensitive property for nice+19 still remained,
+and we never got a single complaint about nice +19 being too _weak_ in
+terms of CPU utilization, we only got complaints about it (still) being
+too _strong_ :-)
+
+To sum it up: we always wanted to make nice levels more consistent, but
+within the constraints of HZ and jiffies and their nasty design level
+coupling to timeslices and granularity it was not really viable.
+
+The second (less frequent but still periodically occuring) complaint
+about Linux's nice level support was its assymetry around the origo
+(which you can see demonstrated in the picture above), or more
+accurately: the fact that nice level behavior depended on the _absolute_
+nice level as well, while the nice API itself is fundamentally
+"relative":
+
+ int nice(int inc);
+
+ asmlinkage long sys_nice(int increment)
+
+(the first one is the glibc API, the second one is the syscall API.)
+Note that the 'inc' is relative to the current nice level. Tools like
+bash's "nice" command mirror this relative API.
+
+With the old scheduler, if you for example started a niced task with +1
+and another task with +2, the CPU split between the two tasks would
+depend on the nice level of the parent shell - if it was at nice -10 the
+CPU split was different than if it was at +5 or +10.
+
+A third complaint against Linux's nice level support was that negative
+nice levels were not 'punchy enough', so lots of people had to resort to
+run audio (and other multimedia) apps under RT priorities such as
+SCHED_FIFO. But this caused other problems: SCHED_FIFO is not starvation
+proof, and a buggy SCHED_FIFO app can also lock up the system for good.
+
+The new scheduler in v2.6.23 addresses all three types of complaints:
+
+To address the first complaint (of nice levels being not "punchy"
+enough), the scheduler was decoupled from 'time slice' and HZ concepts
+(and granularity was made a separate concept from nice levels) and thus
+it was possible to implement better and more consistent nice +19
+support: with the new scheduler nice +19 tasks get a HZ-independent
+1.5%, instead of the variable 3%-5%-9% range they got in the old
+scheduler.
+
+To address the second complaint (of nice levels not being consistent),
+the new scheduler makes nice(1) have the same CPU utilization effect on
+tasks, regardless of their absolute nice levels. So on the new
+scheduler, running a nice +10 and a nice 11 task has the same CPU
+utilization "split" between them as running a nice -5 and a nice -4
+task. (one will get 55% of the CPU, the other 45%.) That is why nice
+levels were changed to be "multiplicative" (or exponential) - that way
+it does not matter which nice level you start out from, the 'relative
+result' will always be the same.
+
+The third complaint (of negative nice levels not being "punchy" enough
+and forcing audio apps to run under the more dangerous SCHED_FIFO
+scheduling policy) is addressed by the new scheduler almost
+automatically: stronger negative nice levels are an automatic
+side-effect of the recalibrated dynamic range of nice levels.

/proc/<pid>/schedstat
----------------
schedstats also adds a new /proc/<pid/schedstat file to include some of
the same information on a per-process level. There are three fields in
-this file correlating to fields 20, 21, and 22 in the CPU fields, but
-they only apply for that process.
+this file correlating for that process to:
+ 1) time spent on the cpu
+ 2) time spent waiting on a runqueue
+ 3) # of timeslices run on this cpu
A program could be easily written to make use of these extra fields to
report on how well a particular process or set of processes is faring
under the scheduler's policies. A simple version of such a program is
available at

-/* This is the kernel's entry point into the floating point emulator.
-It is called from the kernel with code similar to this:
-
- mov fp, #0
- teqp pc, #PSR_I_BIT | SVC_MODE
- ldr r4, .LC2
- ldr pc, [r4] @ Call FP module USR entry point
-
-The kernel expects the emulator to return via one of two possible
-points of return it passes to the emulator. The emulator, if
-successful in its emulation, jumps to ret_from_exception and the
-kernel takes care of returning control from the trap to the user code.
-If the emulator is unable to emulate the instruction, it returns to
-fpundefinstr and the kernel halts the user program with a core dump.
-
-This routine does four things:
-
-1) It saves SP into a variable called userRegisters. The kernel has
-created a struct pt_regs on the stack and saved the user registers
-into it. See /usr/include/asm/proc/ptrace.h for details. The
-emulator code uses userRegisters as the base of an array of words from
-which the contents of the registers can be extracted.
-
-2) It locates the FP emulator work area within the TSS structure and
-points `fpa11' to it.
-
-3) It calls EmulateAll to emulate a floating point instruction.
-EmulateAll returns 1 if the emulation was successful, or 0 if not.
-
-4) If an instruction has been emulated successfully, it looks ahead at
-the next instruction. If it is a floating point instruction, it
-executes the instruction, without returning to user space. In this
-way it repeatedly looks ahead and executes floating point instructions
-until it encounters a non floating point instruction, at which time it
-returns via _fpreturn.
-
-This is done to reduce the effect of the trap overhead on each
-floating point instructions. GCC attempts to group floating point
-instructions to allow the emulator to spread the cost of the trap over
-several floating point instructions. */

-The work in this architecture (ARM26) is that of a great many people.
-
-This is what has happened:
-
-I [Ian Molton] have been trying to repair the ARM26 architecture support, but it has become an impossible task whilst it is still merged with the ARM32 (arch/arm) code. The ARM26 code is too different to be sensible to keep with the ARM32 code now, and Russell King really doesnt have the time to maintain the ARM26 code. Add to that that most ARM32 developers dont know about or care about ARM26 when writing patches, and you have a reall mess.
-
-As a result, I've split it off into a new architecture of its own. I've named it arm26 since these CPUs have only a 26 bit address space, unlike the other ARMs.
-
-The upheaval in moving around so many source files and chopping out vasty ammounts of cruft was enormous, and the copyright of many files is sometimes unclear. Because of this, I am writing this, in order that no-one is left out / misaccredited / blamed for any of the code.
-
-People I KNOW have made major contributions to the code:
-
-David Alan Gilbert (former maintainer of ARM26 bits)
-Philip Blundell
-Russell King
-Keith Owens
-
-also thanks to Nicholas Pitre for hints, and for the basis or our XIP support.
-
-Currently maintaing the code are
-
-Ian Molton (Maintainer / Archimedes)
-John Appleby (kernel / A5K)
-
-If anyone has a problem with attributions in header files / source files, please do contact me to straighten things out.

- * Dev_id must be globally unique. Normally the address of the

- * receives this value it makes sense to use it.
- *
- * If your interrupt is shared you must pass a non NULL dev_id
- * as this is required when freeing the interrupt.

-
- 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
- multiplies two USItype integers MULTIPLER and MULTIPLICAND,
- and generates a two-part USItype product in HIGH_PROD and
- LOW_PROD.
-
- 2) __umulsidi3(a,b) multiplies two USItype integers A and B,
- and returns a UDItype product. This is just a variant of umul_ppmm.
-
- 3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator) divides a two-word unsigned integer, composed by the
- integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
- places the quotient in QUOTIENT and the remainder in REMAINDER.
- HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
- If, in addition, the most significant bit of DENOMINATOR must be 1,
- then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
- 4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
- denominator). Like udiv_qrnnd but the numbers are signed. The
- quotient is rounded towards 0.
-
- 5) count_leading_zeros(count, x) counts the number of zero-bits from
- the msb to the first non-zero bit. This is the number of steps X
- needs to be shifted left to set the msb. Undefined for X == 0.
-
- 6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
- high_addend_2, low_addend_2) adds two two-word unsigned integers,
- composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
- LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
- LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
- lost.
-
- 7) sub_ddmmss(high_difference, low_difference, high_minuend,
- low_minuend, high_subtrahend, low_subtrahend) subtracts two
- two-word unsigned integers, composed by HIGH_MINUEND_1 and
- LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
- respectively. The result is placed in HIGH_DIFFERENCE and
- LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
- and is lost.
-
- If any of these macros are left undefined for a particular CPU,
- C macros are used. */

- * Requirement:

- * second level page tables on 32-bit ARMs.
- *
- * FIXME - this comment is *out of date*
- * Theory:
- * We "misuse" the Linux memory management system. We use alloc_page
- * to allocate a page and then mark it as reserved. The Linux memory
- * management system will then ignore the "offset", "next_hash" and
- * "pprev_hash" entries in the mem_map for this page.
- *
- * We then use a bitstring in the "offset" field to mark which segments
- * of the page are in use, and manipulate this as required during the
- * allocation and freeing of these small pages.
- *
- * We also maintain a queue of pages being used for this purpose using
- * the "next_hash" and "pprev_hash" entries of mem_map;

- * fpa11.h - Add documentation
- - remove userRegisters pointer from this structure.
- - add new method to obtain integer register values.
- * softfloat.c - Remove float128
- * softfloat.h - Remove float128
- * softfloat-specialize - Remove float128
-
- * The FPA11 structure is not a kernel-specific data structure.
- It is used by users of ptrace to examine the values of the
- floating point registers. Therefore, any changes to the
- FPA11 structure (size or position of elements contained
- within) have to be well thought out.
-
- * Since 128-bit float requires the FPA11 structure to change
- size, it has been removed. 128-bit float is currently unused,
- and needs various things to be re-worked so that we won't
- overflow the available space in the task structure.
-
- * The changes are designed to break any patch that goes on top
- of this code, so that the authors properly review their changes.
-
-1999-08-19 Scott Bambrough <scottb@netwinder.org>
-
- * fpmodule.c - Changed version number to 0.95
- * fpa11.h - modified FPA11, FPREG structures
- * fpa11.c - Changes due to FPA11, FPREG structure alterations.
- * fpa11_cpdo.c - Changes due to FPA11, FPREG structure alterations.
- * fpa11_cpdt.c - Changes due to FPA11, FPREG structure alterations.
- * fpa11_cprt.c - Changes due to FPA11, FPREG structure alterations.
- * single_cpdo.c - Changes due to FPA11, FPREG structure alterations.
- * double_cpdo.c - Changes due to FPA11, FPREG structure alterations.
- * extended_cpdo.c - Changes due to FPA11, FPREG structure alterations.
-
- * I discovered several bugs. First and worst is that the kernel
- passes in a pointer to the FPE's state area. This is defined
- as a struct user_fp (see user.h). This pointer was cast to a
- FPA11*. Unfortunately FPA11 and user_fp are of different sizes;
- user_fp is smaller. This meant that the FPE scribbled on things
- below its area, which is bad, as the area is in the thread_struct
- embedded in the process task structure. Thus we were scribbling
- over one of the most important structures in the entire OS.
-
- * user_fp and FPA11 have now been harmonized. Most of the changes
- in the above code were dereferencing problems due to moving the
- register type out of FPREG, and getting rid of the union variable
- fpvalue.
-
- * Second I noticed resetFPA11 was not always being called for a
- task. This should happen on the first floating point exception
- that occurs. It is controlled by init_flag in FPA11. The
- comment in the code beside init_flag state the kernel guarantees
- this to be zero. Not so. I found that the kernel recycles task
- structures, and that recycled ones may not have init_flag zeroed.
- I couldn't even find anything that guarantees it is zeroed when
- when the task structure is initially allocated. In any case
- I now initialize the entire FPE state in the thread structure to
- zero when allocated and recycled. See alloc_task_struct() and
- flush_thread() in arch/arm/process.c. The change to
- alloc_task_struct() may not be necessary, but I left it in for
- completeness (better safe than sorry).

-/* This is the kernel's entry point into the floating point emulator.
-It is called from the kernel with code similar to this:
-
- mov fp, #0
- teqp pc, #PSR_I_BIT | MODE_SVC
- ldr r4, .LC2
- ldr pc, [r4] @ Call FP module USR entry point
-
-The kernel expects the emulator to return via one of two possible
-points of return it passes to the emulator. The emulator, if
-successful in its emulation, jumps to ret_from_exception and the
-kernel takes care of returning control from the trap to the user code.
-If the emulator is unable to emulate the instruction, it returns to
-fpundefinstr and the kernel halts the user program with a core dump.
-
-This routine does four things:
-
-1) It saves SP into a variable called userRegisters. The kernel has
-created a struct pt_regs on the stack and saved the user registers
-into it. See /usr/include/asm/proc/ptrace.h for details. The
-emulator code uses userRegisters as the base of an array of words from
-which the contents of the registers can be extracted.
-
-2) It locates the FP emulator work area within the TSS structure and
-points `fpa11' to it.
-
-3) It calls EmulateAll to emulate a floating point instruction.
-EmulateAll returns 1 if the emulation was successful, or 0 if not.
-
-4) If an instruction has been emulated successfully, it looks ahead at
-the next instruction. If it is a floating point instruction, it
-executes the instruction, without returning to user space. In this
-way it repeatedly looks ahead and executes floating point instructions
-until it encounters a non floating point instruction, at which time it
-returns via _fpreturn.
-
-This is done to reduce the effect of the trap overhead on each
-floating point instructions. GCC attempts to group floating point
-instructions to allow the emulator to spread the cost of the trap over
-several floating point instructions. */

-/*
- * Detailed Description:
- *
- * This block implements the I2C interface to the slave devices like the
- * Atmel 24C32 EEPROM and the MAX 1619 Sensors device. The I2C Master interface
- * can be controlled by the SCMB block. And the SCMB block kicks in only when
- * using the Ethernet Mode of operation and __not__ the SysAD mode
- *
- * The SCMB controls the two modes: MDIO and the I2C. The MDIO mode is used to
- * communicate with the Quad-PHY from Marvel. The I2C is used to communicate
- * with the I2C slave devices. It seems that the driver does not explicitly
- * deal with the control of SDA and SCL serial lines. So, the driver will set
- * the slave address, drive the command and then the data. The SCMB will then
- * control the two serial lines as required.
- *
- * It seems the documents are very unclear abt this. Hence, I took some time
- * out to write the desciption to have an idea of how the I2C can actually
- * work. Currently, this Linux driver wont be integrated into the generic Linux
- * I2C framework. And finally, the I2C interface is also known as the 2BI
- * interface. 2BI means 2-bit interface referring to SDA and SCL serial lines
- * respectively.

- * linux/kernel/arch/arm/drivers/block/fd1772.c
- * Based on ataflop.c in the m68k Linux
- * Copyright (C) 1993 Greg Harp
- * Atari Support by Bjoern Brauel, Roman Hodek
- * Archimedes Support by Dave Gilbert (linux@treblig.org)
- *
- * Big cleanup Sep 11..14 1994 Roman Hodek:
- * - Driver now works interrupt driven
- * - Support for two drives; should work, but I cannot test that :-(
- * - Reading is done in whole tracks and buffered to speed up things
- * - Disk change detection and drive deselecting after motor-off
- * similar to TOS
- * - Autodetection of disk format (DD/HD); untested yet, because I
- * don't have an HD drive :-(
- *
- * Fixes Nov 13 1994 Martin Schaller:
- * - Autodetection works now
- * - Support for 5 1/4" disks
- * - Removed drive type (unknown on atari)
- * - Do seeks with 8 Mhz
- *
- * Changes by Andreas Schwab:
- * - After errors in multiple read mode try again reading single sectors
- * (Feb 1995):
- * - Clean up error handling
- * - Set blk_size for proper size checking
- * - Initialize track register when testing presence of floppy
- * - Implement some ioctl's
- *
- * Changes by Torsten Lang:
- * - When probing the floppies we should add the FDC1772CMDADD_H flag since
- * the FDC1772 will otherwise wait forever when no disk is inserted...
- *
- * Things left to do:
- * - Formatting
- * - Maybe a better strategy for disk change detection (does anyone
- * know one?)
- * - There are some strange problems left: The strangest one is
- * that, at least on my TT (4+4MB), the first 2 Bytes of the last
- * page of the TT-Ram (!) change their contents (some bits get
- * set) while a floppy DMA is going on. But there are no accesses
- * to these memory locations from the kernel... (I tested that by
- * making the page read-only). I cannot explain what's going on...
- * - Sometimes the drive-change-detection stops to work. The
- * function is still called, but the WP bit always reads as 0...
- * Maybe a problem with the status reg mode or a timing problem.
- * Note 10/12/94: The change detection now seems to work reliably.
- * There is no proof, but I've seen no hang for a long time...
- *
- * ARCHIMEDES changes: (gilbertd@cs.man.ac.uk)
- * 26/12/95 - Changed all names starting with FDC to FDC1772
- * Removed all references to clock speed of FDC - we're stuck with 8MHz
- * Modified disk_type structure to remove HD formats
- *
- * 7/ 1/96 - Wrote FIQ code, removed most remaining atariisms
- *
- * 13/ 1/96 - Well I think its read a single sector; but there is a problem
- * fd_rwsec_done which is called in FIQ mode starts another transfer
- * off (in fd_rwsec) while still in FIQ mode. Because its still in
- * FIQ mode it can't service the DMA and loses data. So need to
- * heavily restructure.
- * 14/ 1/96 - Found that the definitions of the register numbers of the
- * FDC were multiplied by 2 in the header for the 16bit words
- * of the atari so half the writes were going in the wrong place.
- * Also realised that the FIQ entry didn't make any attempt to
- * preserve registers or return correctly; now in assembler.
- *
- * 11/ 2/96 - Hmm - doesn't work on real machine. Auto detect doesn't
- * and hacking that past seems to wait forever - check motor
- * being turned on.
- *
- * 17/ 2/96 - still having problems - forcing track to -1 when selecting
- * new drives seems to allow it to read first few sectors
- * but then we get solid hangs at apparently random places
- * which change depending what is happening.
- *
- * 9/ 3/96 - Fiddled a lot of stuff around to move to kernel 1.3.35
- * A lot of fiddling in DMA stuff. Having problems with it
- * constnatly thinking its timeing out. Ah - its timeout
- * was set to (6*HZ) rather than jiffies+(6*HZ). Now giving
- * duff data!
- *
- * 5/ 4/96 - Made it use the new IOC_ macros rather than *ioc
- * Hmm - giving unexpected FIQ and then timeouts
- * 18/ 8/96 - Ran through indent -kr -i8
- * Some changes to disc change detect; don't know how well it
- * works.
- * 24/ 8/96 - Put all the track buffering code back in from the atari
- * code - I wonder if it will still work... No :-)
- * Still works if I turn off track buffering.
- * 25/ 8/96 - Changed the timer expires that I'd added back to be
- * jiffies + ....; and it all sprang to life! Got 2.8K/sec
- * off a cp -r of a 679K disc (showed 94% cpu usage!)
- * (PC gets 14.3K/sec - 0% CPU!) Hmm - hard drive corrupt!
- * Also perhaps that compile was with cache off.
- * changed cli in fd_readtrack_check to cliIF
- * changed vmallocs to kmalloc (whats the difference!!)
- * Removed the busy wait loop in do_fd_request and replaced
- * by a routine on tq_immediate; only 11% cpu on a dd off the
- * raw disc - but the speed is the same.
- * 1/ 9/96 - Idea (failed!) - set the 'disable spin-up sequence'
- * when we read the track if we know the motor is on; didn't
- * help - perhaps we have to do it in stepping as well.
- * Nope. Still doesn't help.
- * Hmm - what seems to be happening is that fd_readtrack_check
- * is never getting called. Its job is to terminate the read
- * just after we think we should have got the data; otherwise
- * the fdc takes 1 second to timeout; which is what's happening
- * Now I can see 'readtrack_timer' being set (which should do the
- * call); but it never seems to be called - hmm!
- * OK - I've moved the check to my tq_immediate code -
- * and it WORKS! 13.95K/second at 19% CPU.
- * I wish I knew why that timer didn't work.....
- *
- * 16/11/96 - Fiddled and frigged for 2.0.18
- *
- * DAG 30/01/99 - Started frobbing for 2.2.1
- * DAG 20/06/99 - A little more frobbing:
- * Included include/asm/uaccess.h for get_user/put_user
- *
- * DAG 1/09/00 - Dusted off for 2.4.0-test7
- * MAX_SECTORS was name clashing so it is now FD1772_...
- * Minor parameter, name layouts for 2.4.x differences

-/*
- * Change list:
- *
- * 3/2/96:DAG: Started a change list :-)
- * Set the hardsect_size pointers up since we are running 256 byte
- * sectors
- * Added DMA code, put it into the rw_intr
- * Moved RCAL out of generic interrupt code - don't want to do it
- * while DMA'ing - its now in individual handlers.
- * Took interrupt handlers off task queue lists and called
- * directly - not sure of implications.
- *
- * 18/2/96:DAG: Well its reading OK I think, well enough for image file code
- * to find the image file; but now I've discovered that I actually
- * have to put some code in for image files.
- *
- * Added stuff for image files; seems to work, but I've not
- * got a multisegment image file (I don't think!).
- * Put in a hack (yep a real hack) for multiple cylinder reads.
- * Not convinced its working.
- *
- * 5/4/96:DAG: Added asm/hardware.h and use IOC_ macros
- * Rewrote dma code in mfm.S (again!) - now takes a word at a time
- * from main RAM for speed; still doesn't feel speedy!
- *
- * 20/4/96:DAG: After rewriting mfm.S a heck of a lot of times and speeding
- * things up, I've finally figured out why its so damn slow.
- * Linux is only reading a block at a time, and so you never
- * get more than 1K per disc revoloution ~=60K/second.
- *
- * 27/4/96:DAG: On Russell's advice I change ll_rw_blk.c to ask it to
- * join adjacent blocks together. Everything falls flat on its
- * face.
- * Four hours of debugging later; I hadn't realised that
- * ll_rw_blk would be so generous as to join blocks whose
- * results aren't going into consecutive buffers.
- *
- * OK; severe rehacking of mfm_rw_interrupt; now end_request's
- * as soon as its DMA'd each request. Odd thing is that
- * we are sometimes getting interrupts where we are not transferring
- * any data; why? Is that what happens when you miss? I doubt
- * it; are we too fast? No - its just at command ends. Got 240K/s
- * better than before, but RiscOS hits 480K/s
- *
- * 25/6/96:RMK: Fixed init code to allow the MFM podule to work. Increased the
- * number of errors for my Miniscribe drive (8425).
- *
- * 30/6/96:DAG: Russell suggested that a check drive 0 might turn the LEDs off
- * - so in request_done just before it clears Busy it sends a
- * check drive 0 - and the LEDs go off!!!!
- *
- * Added test for mainboard controller. - Removes need for separate
- * define.
- *
- * 13/7/96:DAG: Changed hardware sectore size to 512 in attempt to make
- * IM drivers work.
- * 21/7/96:DAG: Took out old image file stuff (accessing it now produces an IO
- * error.)
- *
- * 17/8/96:DAG: Ran through indent -kr -i8; evil - all my nice 2 character indents
- * gone :-( Hand modified afterwards.
- * Took out last remains of the older image map system.
- *
- * 22/9/96:DAG: Changed mfm.S so it will carry on DMA'ing til; BSY is dropped
- * Changed mfm_rw_intr so that it doesn't follow the error
- * code until BSY is dropped. Nope - still broke. Problem
- * may revolve around when it reads the results for the error
- * number?
- *
- *16/11/96:DAG: Modified for 2.0.18; request_irq changed
- *
- *17/12/96:RMK: Various cleanups, reorganisation, and the changes for new IO system.
- * Improved probe for onboard MFM chip - it was hanging on my A5k.
- * Added autodetect CHS code such that we don't rely on the presence
- * of an ADFS boot block. Added ioport resource manager calls so
- * that we don't clash with already-running hardware (eg. RiscPC Ether
- * card slots if someone tries this)!
- *
- * 17/1/97:RMK: Upgraded to 2.1 kernels.
- *
- * 4/3/98:RMK: Changed major number to 21.
- *
- * 27/6/98:RMK: Changed asm/delay.h to linux/delay.h for mdelay().
- */
-
-/*
- * Possible enhancements:
- * Multi-thread the code so that it is possible that while one drive
- * is seeking, the other one can be reading data/seeking as well.
- * This would be a performance boost with dual drive systems.

+Welcome, friend reader, to lguest.
+
+Lguest is an adventure, with you, the reader, as Hero. I can't think of many
+5000-line projects which offer both such capability and glimpses of future
+potential; it is an exciting time to be delving into the source!
+
+But be warned; this is an arduous journey of several hours or more! And as we
+know, all true Heroes are driven by a Noble Goal. Thus I offer a Beer (or
+equivalent) to anyone I meet who has completed this documentation.
+
+So get comfortable and keep your wits about you (both quick and humorous).
+Along your way to the Noble Goal, you will also gain masterly insight into
+lguest, and hypervisors and x86 virtualization in general.
+
+Our Quest is in seven parts: (best read with C highlighting turned on)
+
+I) Preparation
+ - In which our potential hero is flown quickly over the landscape for a
+ taste of its scope. Suitable for the armchair coders and other such
+ persons of faint constitution.
+
+II) Guest
+ - Where we encounter the first tantalising wisps of code, and come to
+ understand the details of the life of a Guest kernel.
+
+III) Drivers
+ - Whereby the Guest finds its voice and become useful, and our
+ understanding of the Guest is completed.
+
+IV) Launcher
+ - Where we trace back to the creation of the Guest, and thus begin our
+ understanding of the Host.
+
+V) Host
+ - Where we master the Host code, through a long and tortuous journey.
+ Indeed, it is here that our hero is tested in the Bit of Despair.
+
+VI) Switcher
+ - Where our understanding of the intertwined nature of Guests and Hosts
+ is completed.
+
+VII) Mastery
+ - Where our fully fledged hero grapples with the Great Question:
+ "What next?"
+
+make Preparation!
+Rusty Russell.

+ *
+ * We keep things simple in two ways. First, we start with a normal Linux

+ * kernels the same way we'd run processes. We call the first kernel the Host,
+ * and the others the Guests. The program which sets up and configures Guests
+ * (such as the example in Documentation/lguest/lguest.c) is called the
+ * Launcher.
+ *
+ * Secondly, we only run specially modified Guests, not normal kernels. When
+ * you set CONFIG_LGUEST to 'y' or 'm', this automatically sets
+ * CONFIG_LGUEST_GUEST=y, which compiles this file into the kernel so it knows
+ * how to be a Guest. This means that you can use the same kernel you boot
+ * normally (ie. as a Host) as a Guest.
*
+ * These Guests know that they cannot do privileged operations, such as disable
+ * interrupts, and that they have to ask the Host to do such things explicitly.
+ * This file consists of all the replacements for such low-level native
+ * hardware operations: these special Guest versions call the Host.
+ *
+ * So how does the kernel know it's a Guest? The Guest starts at a special
+ * entry point marked with a magic string, which sets up a few things then
+ * calls here. We replace the native functions in "struct paravirt_ops"
+ * with our Guest versions, then boot like normal. :*/

+ * Page Table Handling.
+ *
+ * Now would be a good time to take a rest and grab a coffee or similarly
+ * relaxing stimulant. The easy parts are behind us, and the trek gradually
+ * winds uphill from here.
+ *
+ * Quick refresher: memory is divided into "pages" of 4096 bytes each. The CPU
+ * maps virtual addresses to physical addresses using "page tables". We could
+ * use one huge index of 1 million entries: each address is 4 bytes, so that's
+ * 1024 pages just to hold the page tables. But since most virtual addresses
+ * are unused, we use a two level index which saves space. The CR3 register
+ * contains the physical address of the top level "page directory" page, which
+ * contains physical addresses of up to 1024 second-level pages. Each of these
+ * second level pages contains up to 1024 physical addresses of actual pages,
+ * or Page Table Entries (PTEs).
+ *
+ * Here's a diagram, where arrows indicate physical addresses:
+ *
+ * CR3 ---> +---------+
+ * | --------->+---------+
+ * | | | PADDR1 |
+ * Top-level | | PADDR2 |
+ * (PMD) page | | |
+ * | | Lower-level |
+ * | | (PTE) page |
+ * | | | |
+ * .... ....
+ *
+ * So to convert a virtual address to a physical address, we look up the top
+ * level, which points us to the second level, which gives us the physical
+ * address of that page. If the top level entry was not present, or the second
+ * level entry was not present, then the virtual address is invalid (we
+ * say "the page was not mapped").
+ *
+ * Put another way, a 32-bit virtual address is divided up like so:
+ *
+ * 1 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
+ * |<---- 10 bits ---->|<---- 10 bits ---->|<------ 12 bits ------>|
+ * Index into top Index into second Offset within page
+ * page directory page pagetable page
+ *
+ * The kernel spends a lot of time changing both the top-level page directory
+ * and lower-level pagetable pages. The Guest doesn't know physical addresses,
+ * so while it maintains these page tables exactly like normal, it also needs
+ * to keep the Host informed whenever it makes a change: the Host will create
+ * the real page tables based on the Guests'.
+ */
+

+ * we do the "iret".
+ *
+ * There are two problems with this: firstly, we need to use a register to do

+ * problem is easy to solve: push %eax on the stack so we can use it, and then
+ * restore it at the end just before the real "iret".
+ *
+ * The second is harder: copying eflags to lguest_data.irq_enabled will turn
+ * interrupts on before we're finished, so we could be interrupted before we
+ * return to userspace or wherever. Our solution to this is to surround the
+ * code with lguest_noirq_start: and lguest_noirq_end: labels. We tell the

+ enable hot key handling by default, and also starts up with a mostly

+
+ This option should be enabled if you have a new enough HAL or other

+ firmware and enables it automatically.
+
+ If unsure, say N here to retain the old behaviour of ibm-acpi, and
+ thinkpad-acpi up to kernel 2.6.21: userspace will have to enable and
+ set up the thinkpad-acpi hot key handling using the sysfs interace

+ * Firstly, it doesn't use "NAPI": the networking's New API, and is poorer for

+ * network interfaces. Lack of NAPI can mean competition at higher loads."
+ *
+ * He also points out that we don't implement set_mac_address, so users cannot
+ * change the devices hardware address. When I asked why one would want to:
+ * "Bonding, and situations where you /do/ want the MAC address to "leak" out
+ * of the host onto the wider net."
+ *
+ * Finally, he would like module unloading: "It is not unrealistic to think of
+ * [un|re|]loading the net support module in an lguest guest. And, adding
+ * module support makes the programmer more responsible, because they now have
+ * to learn to clean up after themselves. Any driver that cannot clean up

+ * Things to know
+ * - IRQ delivery is asynchronous to the PCI bus
+ * - Blocking the local CPU IRQ via spin locks was too slow
+ * - The chip has register windows needing locking work
+ *
+ * So the path was once (I say once as people appear to have changed it
+ * in the mean time and it now looks rather bogus if the changes to use
+ * disable_irq_nosync_irqsave are disabling the local IRQ)
+ *
+ *
+ * Take the page lock
+ * Mask the IRQ on chip
+ * Disable the IRQ (but not mask locally- someone seems to have
+ * broken this with the lock validator stuff)
+ * [This must be _nosync as the page lock may otherwise
+ * deadlock us]
+ * Drop the page lock and turn IRQs back on
+ *
+ * At this point an existing IRQ may still be running but we can't
+ * get a new one
+ *
+ * Take the lock (so we know the IRQ has terminated) but don't mask
+ * the IRQs on the processor
+ * Set irqlock [for debug]
+ *
+ * Transmit (slow as ****)
+ *
+ * re-enable the IRQ
+ *
+ *
+ * We have to use disable_irq because otherwise you will get delayed
+ * interrupts on the APIC bus deadlocking the transmit path.

- * IO port access primitives
- * -------------------------
- *
- * The ARM doesn't have special IO access instructions; all IO is memory
- * mapped. Note that these are defined to perform little endian accesses
- * only. Their primary purpose is to access PCI and ISA peripherals.
- *
- * Note that for a big endian machine, this implies that the following
- * big endian mode connectivity is in place, as described by numerious
- * ARM documents:
- *
- * PCI: D0-D7 D8-D15 D16-D23 D24-D31
- * ARM: D24-D31 D16-D23 D8-D15 D0-D7
- *
- * The machine specific io.h include defines __io to translate an "IO"
- * address to a memory address.
- *
- * Note that we prevent GCC re-ordering or caching values in expressions
- * by introducing sequence points into the in*() definitions. Note that
- * __raw_* do not guarantee this behaviour.

- * Terminology: PGD = Page Directory, PMD = Page Middle Directory,

- *
- * on arm26 we have no 2nd level page table. we simulate this by removing the
- * PMD.
- *
- * pgd_none is 0 to prevernt pmd_alloc() calling __pmd_alloc(). This causes it
- * to return pmd_offset(pgd,addr) which is a pointer to the pgd (IOW, a no-op).
- *
- * however, to work this way, whilst we are allocating 32 pgds, containing 32
- * PTEs, the actual work is done on the PMDs, thus:
- *
- * instead of mm->pgd->pmd->pte
- * we have mm->pgdpmd->pte
- *
- * IOW, think of PGD operations and PMD ones as being the same thing, just
- * that PGD stuff deals with the mm_struct side of things, wheras PMD stuff
- * deals with the pte side of things.
- *
- * additionally, we store some bits in the PGD and PTE pointers:
- * PGDs:
- * o The lowest (1) bit of the PGD is to determine if it is present or swap.
- * o The 2nd bit of the PGD is unused and must be zero.
- * o The top 6 bits of the PGD must be zero.
- * PTEs:
- * o The lower 5 bits of a pte are flags. bit 1 is the 'present' flag. The
- * others determine the pages attributes.
- *
- * the pgd_val, pmd_val, and pte_val macros seem to be private to our code.
- * They get the RAW value of the PGD/PMD/PTE entry, including our flags
- * encoded into the pointers.
- *
- * The pgd_offset, pmd_offset, and pte_offset macros are used by the kernel,
- * so they shouldnt have our flags attached.
- *
- * If you understood that, feel free to explain it to me...

- * What is the most efficient way of loading/storing an unaligned value?
- *
- * That is the subject of this file. Efficiency here is defined as
- * minimum code size with minimum register usage for the common cases.
- * It is currently not believed that long longs are common, so we
- * trade efficiency for the chars, shorts and longs against the long
- * longs.
- *
- * Current stats with gcc 2.7.2.2 for these functions:
- *
- * ptrsize get: code regs put: code regs
- * 1 1 1 1 2
- * 2 3 2 3 2
- * 4 7 3 7 3
- * 8 20 6 16 6
- *
- * gcc 2.95.1 seems to code differently:
- *
- * ptrsize get: code regs put: code regs
- * 1 1 1 1 2
- * 2 3 2 3 2
- * 4 7 4 7 4
- * 8 19 8 15 6
- *
- * which may or may not be more efficient (depending upon whether
- * you can afford the extra registers). Hopefully the gcc 2.95
- * is inteligent enough to decide if it is better to use the
- * extra register, but evidence so far seems to suggest otherwise.
- *
- * Unfortunately, gcc is not able to optimise the high word
- * out of long long >> 32, or the low word from long long << 32

-/* Core file format: The core file is written in such a way that gdb
- can understand it and provide useful information to the user (under
- linux we use the 'trad-core' bfd). There are quite a number of
- obstacles to being able to view the contents of the floating point
- registers, and until these are solved you will not be able to view the
- contents of them. Actually, you can read in the core file and look at
- the contents of the user struct to find out what the floating point
- registers contain.
- The actual file contents are as follows:
- UPAGE: 1 page consisting of a user struct that tells gdb what is present
- in the file. Directly after this is a copy of the task_struct, which
- is currently not used by gdb, but it may come in useful at some point.
- All of the registers are stored as part of the upage. The upage should
- always be only one page.
- DATA: The data area is stored. We use current->end_text to
- current->brk to pick up all of the user variables, plus any memory
- that may have been malloced. No attempt is made to determine if a page
- is demand-zero or if a page is totally unused, we just cover the entire
- range. All of the addresses are rounded in such a way that an integral
- number of pages is written.
- STACK: We need the stack information in order to get a meaningful
- backtrace. We need to write the data from (esp) to
- current->start_stack, so we round each of these off in order to be able
- to write an integer number of pages.
- The minimum core file size is 3 pages, or 12288 bytes.

+ * terminated with a 0.
+ *
+ * I/O is organized by keys: BIND_DMA attaches buffers to a particular key, and
+ * SEND_DMA transfers to buffers bound to particular key. By convention, keys
+ * correspond to a physical address within the device's page. This means that
+ * devices will never accidentally end up with the same keys, and allows the
+ * Host use The Futex Trick (as we'll see later in our journey).
+ *
+ * SEND_DMA simply indicates a key to send to, and the physical address of the
+ * "struct lguest_dma" to send. The Host will write the number of bytes
+ * transferred into the "struct lguest_dma"'s used_len member.
+ *
+ * BIND_DMA indicates a key to bind to, a pointer to an array of "struct
+ * lguest_dma"s ready for receiving, the size of that array, and an interrupt
+ * to trigger when data is received. The Host will only allow transfers into
+ * buffers with a used_len of zero: it then sets used_len to the number of
+ * bytes transferred and triggers the interrupt for the Guest to process the

- * This code is derived from ite8172.c, which is written by Steve Longerbeam.
- *
- * Features:
- * Currently we only support the following capabilities:
- * . mono output to PCM L/R (line out).
- * . stereo output to PCM L/R (line out).
- * . mono input from PCM L (line in).
- * . stereo output from PCM (line in).
- * . sampling rate at 48k or variable sampling rate
- * . support /dev/dsp, /dev/mixer devices, standard OSS devices.
- * . only support 16-bit PCM format (hardware limit, no software
- * translation)
- * . support duplex, but no trigger or realtime.
- *
- * Specifically the following are not supported:
- * . app-set frag size.
- * . mmap'ed buffer access
- */
-
-/*
- * Original comments from ite8172.c file.

-
-/*
- *
- * Notes:
- *
- * 1. Much of the OSS buffer allocation, ioctl's, and mmap'ing are
- * taken, slightly modified or not at all, from the ES1371 driver,
- * so refer to the credits in es1371.c for those. The rest of the
- * code (probe, open, read, write, the ISR, etc.) is new.
- * 2. The following support is untested:
- * * Memory mapping the audio buffers, and the ioctl controls that go
- * with it.
- * * S/PDIF output.
- * 3. The following is not supported:
- * * I2S input.
- * * legacy audio mode.
- * 4. Support for volume button interrupts is implemented but doesn't
- * work yet.
- *
- * Revision history
- * 02.08.2001 0.1 Initial release
