+
+
+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.
+
+ nodecompose
+ Do not decompose file name characters.
+

+ Used to force write access to volumes that are marked as journalled
+ or locked. Use at your own risk.

+Module Parameters
+-----------------
+
+* 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).

+ * We know that CONFIG_PAGE_OFFSET sets what virtual address the kernel expects
+ * to be. We don't know what that option was, but we can figure it out
+ * approximately by looking at the addresses in the code. I chose the common
+ * case of reading a memory location into the %eax register:
+ *
+ * movl <some-address>, %eax
+ *
+ * This gets encoded as five bytes: "0xA1 <4-byte-address>". For example,
+ * "0xA1 0x18 0x60 0x47 0xC0" reads the address 0xC0476018 into %eax.
+ *
+ * In this example can guess that the kernel was compiled with
+ * CONFIG_PAGE_OFFSET set to 0xC0000000 (it's always a round number). If the
+ * kernel were larger than 16MB, we might see 0xC1 addresses show up, but our
+ * kernel isn't that bloated yet.
+ *
+ * Unfortunately, x86 has variable-length instructions, so finding this
+ * particular instruction properly involves writing a disassembler. Instead,
+ * we rely on statistics. We look for "0xA1" and tally the different bytes
+ * which occur 4 bytes later (the "0xC0" in our example above). When one of

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 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.

- * FIQ support written by Philip Blundell <philb@gnu.org>, 1998.
- *
- * FIQ support re-written by Russell King to be more generic
- *
- * We now properly support a method by which the FIQ handlers can
- * be stacked onto the vector. We still do not support sharing
- * the FIQ vector itself.
- *
- * Operation is as follows:
- * 1. Owner A claims FIQ:
- * - default_fiq relinquishes control.
- * 2. Owner A:
- * - inserts code.
- * - sets any registers,
- * - enables FIQ.
- * 3. Owner B claims FIQ:
- * - if owner A has a relinquish function.
- * - disable FIQs.
- * - saves any registers.
- * - returns zero.
- * 4. Owner B:
- * - inserts code.
- * - sets any registers,
- * - enables FIQ.
- * 5. Owner B releases FIQ:
- * - Owner A is asked to reacquire FIQ:
- * - inserts code.
- * - restores saved registers.
- * - enables FIQ.
- * 6. Goto 3

- 1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
- multiplies two USItype integers MULTIPLER and MULTIPLICAND,

- 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.
-

- * Requirement:
- * We need to be able to allocate naturally aligned memory of finer
- * granularity than the page size. This is typically used for the
- * 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).
-
-1998-11-23 Scott Bambrough <scottb@netwinder.org>
-
- * README.FPE - fix typo in description of lfm/sfm instructions
- * NOTES - Added file to describe known bugs/problems
- * fpmodule.c - Changed version number to 0.94
-
-1998-11-20 Scott Bambrough <scottb@netwinder.org>
-
- * README.FPE - fix description of URD, NRM instructions
- * TODO - remove URD, NRM instructions from TODO list
- * single_cpdo.c - implement URD, NRM
- * double_cpdo.c - implement URD, NRM
- * extended_cpdo.c - implement URD, NRM
-
-1998-11-19 Scott Bambrough <scottb@netwinder.org>
-
- * ChangeLog - Added this file to track changes made.
- * fpa11.c - added code to initialize register types to typeNone
- * fpa11_cpdt.c - fixed bug in storeExtended (typeExtended changed to
- typeDouble in switch statement)

-/* 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.

- This option adds support for ACPI suspend states.
-
- With this option, you will be able to put the system "to sleep".
- Sleep states are low power states for the system and devices. All
- of the system operating state is saved to either memory or disk
- (depending on the state), to allow the system to resume operation
- quickly at your request.
-
- Although this option sounds really nifty, barely any of the device
- drivers have been converted to the new driver model and hence few
- have proper power management support.
-
- This option is not recommended for anyone except those doing driver
- power management development.

- /sys/module/acpi/parameters/debug_layer && debug_level.
- /proc/acpi/info is deprecated by
- /sys/module/acpi/parameters/acpica_version )
+ For backwards compatibility, this option allows
+ depricated /proc/acpi/ files to exist, even when
+ they have been replaced by functions in /sys.
+ The deprecated files (and their replacements) include:
+
+ /proc/acpi/sleep (/sys/power/state)

+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.

+ * A hypervisor allows multiple Operating Systems to run on a single machine.

*
+ * We keep things simple in two ways. First, we start with a normal Linux
+ * kernel and insert a module (lg.ko) which allows us to run other 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

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

+ *
+ * He also points out that we don't implement set_mac_address, so users cannot

+ * "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

+ * 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

+ * Take the lock (so we know the IRQ has terminated) but don't mask

- * 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.

+ * The lguest I/O mechanism is the only way Guests can talk to devices. There
+ * are two hypercalls involved: SEND_DMA for output and BIND_DMA for input. In
+ * each case, "struct lguest_dma" describes the buffer: this contains 16
+ * addr/len pairs, and if there are fewer buffer elements the len array is
+ * 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

+ * struct spi_board_info - board-specific template for a SPI device
+ * @modalias: Initializes spi_device.modalias; identifies the driver.
+ * @platform_data: Initializes spi_device.platform_data; the particular
+ * data stored there is driver-specific.
+ * @controller_data: Initializes spi_device.controller_data; some
+ * controllers need hints about hardware setup, e.g. for DMA.
+ * @irq: Initializes spi_device.irq; depends on how the board is wired.
+ * @max_speed_hz: Initializes spi_device.max_speed_hz; based on limits
+ * from the chip datasheet and board-specific signal quality issues.
+ * @bus_num: Identifies which spi_master parents the spi_device; unused
+ * by spi_new_device(), and otherwise depends on board wiring.
+ * @chip_select: Initializes spi_device.chip_select; depends on how
+ * the board is wired.
+ * @mode: Initializes spi_device.mode; based on the chip datasheet, board
+ * wiring (some devices support both 3WIRE and standard modes), and
+ * possibly presence of an inverter in the chipselect path.
+ *
+ * When adding new SPI devices to the device tree, these structures serve
+ * as a partial device template. They hold information which can't always
+ * be determined by drivers. Information that probe() can establish (such
+ * as the default transfer wordsize) is not included here.
+ *
+ * These structures are used in two places. Their primary role is to
+ * be stored in tables of board-specific device descriptors, which are
+ * declared early in board initialization and then used (much later) to
+ * populate a controller's device tree after the that controller's driver
+ * initializes. A secondary (and atypical) role is as a parameter to
+ * spi_new_device() call, which happens after those controller drivers
+ * are active in some dynamic board configuration models.

-/*
- * 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
