What: /sys/power/disk
-Date: August 2006
+Date: September 2006
Contact: Rafael J. Wysocki <rjw@sisk.pl>
Description:
The /sys/power/disk file controls the operating mode of the
'reboot' - the memory image will be saved by the kernel and
the system will be rebooted.
+ Additionally, /sys/power/disk can be used to turn on one of the
+ two testing modes of the suspend-to-disk mechanism: 'testproc'
+ or 'test'. If the suspend-to-disk mechanism is in the
+ 'testproc' mode, writing 'disk' to /sys/power/state will cause
+ the kernel to disable nonboot CPUs and freeze tasks, wait for 5
+ seconds, unfreeze tasks and enable nonboot CPUs. If it is in
+ the 'test' mode, writing 'disk' to /sys/power/state will cause
+ the kernel to disable nonboot CPUs and freeze tasks, shrink
+ memory, suspend devices, wait for 5 seconds, resume devices,
+ unfreeze tasks and enable nonboot CPUs. Then, we are able to
+ look in the log messages and work out, for example, which code
+ is being slow and which device drivers are misbehaving.
+
The suspend-to-disk method may be chosen by writing to this
file one of the accepted strings:
'platform'
'shutdown'
'reboot'
+ 'testproc'
+ 'test'
It will only change to 'firmware' or 'platform' if the system
supports that.

+
+ <sect1>
+ <title>Overview</title>
+ <sect2>
+ <title>Details</title>
+<para>
+The journalling layer is easy to use. You need to
+first of all create a journal_t data structure. There are
+two calls to do this dependent on how you decide to allocate the physical
+media on which the journal resides. The journal_init_inode() call
+is for journals stored in filesystem inodes, or the journal_init_dev()
+call can be use for journal stored on a raw device (in a continuous range
+of blocks). A journal_t is a typedef for a struct pointer, so when
+you are finally finished make sure you call journal_destroy() on it
+to free up any used kernel memory.
+</para>
+
+<para>
+Once you have got your journal_t object you need to 'mount' or load the journal
+file, unless of course you haven't initialised it yet - in which case you
+need to call journal_create().
+</para>
+
+<para>
+Most of the time however your journal file will already have been created, but
+before you load it you must call journal_wipe() to empty the journal file.
+Hang on, you say , what if the filesystem wasn't cleanly umount()'d . Well, it is the
+job of the client file system to detect this and skip the call to journal_wipe().
+</para>
+
+<para>
+In either case the next call should be to journal_load() which prepares the
+journal file for use. Note that journal_wipe(..,0) calls journal_skip_recovery()
+for you if it detects any outstanding transactions in the journal and similarly
+journal_load() will call journal_recover() if necessary.
+I would advise reading fs/ext3/super.c for examples on this stage.
+[RGG: Why is the journal_wipe() call necessary - doesn't this needlessly
+complicate the API. Or isn't a good idea for the journal layer to hide
+dirty mounts from the client fs]
+</para>
+
+<para>
+Now you can go ahead and start modifying the underlying
+filesystem. Almost.
+</para>
+
+<para>
+
+You still need to actually journal your filesystem changes, this
+is done by wrapping them into transactions. Additionally you
+also need to wrap the modification of each of the buffers
+with calls to the journal layer, so it knows what the modifications
+you are actually making are. To do this use journal_start() which
+returns a transaction handle.
+</para>
+
+<para>
+journal_start()
+and its counterpart journal_stop(), which indicates the end of a transaction
+are nestable calls, so you can reenter a transaction if necessary,
+but remember you must call journal_stop() the same number of times as
+journal_start() before the transaction is completed (or more accurately
+leaves the update phase). Ext3/VFS makes use of this feature to simplify
+quota support.
+</para>
+
+<para>
+Inside each transaction you need to wrap the modifications to the
+individual buffers (blocks). Before you start to modify a buffer you
+need to call journal_get_{create,write,undo}_access() as appropriate,
+this allows the journalling layer to copy the unmodified data if it
+needs to. After all the buffer may be part of a previously uncommitted
+transaction.
+At this point you are at last ready to modify a buffer, and once
+you are have done so you need to call journal_dirty_{meta,}data().
+Or if you've asked for access to a buffer you now know is now longer
+required to be pushed back on the device you can call journal_forget()
+in much the same way as you might have used bforget() in the past.
+</para>
+
+<para>
+A journal_flush() may be called at any time to commit and checkpoint
+all your transactions.
+</para>
+
+<para>
+Then at umount time , in your put_super() (2.4) or write_super() (2.5)
+you can then call journal_destroy() to clean up your in-core journal object.
+</para>
+
+<para>
+Unfortunately there a couple of ways the journal layer can cause a deadlock.
+The first thing to note is that each task can only have
+a single outstanding transaction at any one time, remember nothing
+commits until the outermost journal_stop(). This means
+you must complete the transaction at the end of each file/inode/address
+etc. operation you perform, so that the journalling system isn't re-entered
+on another journal. Since transactions can't be nested/batched
+across differing journals, and another filesystem other than
+yours (say ext3) may be modified in a later syscall.
+</para>
+
+<para>
+The second case to bear in mind is that journal_start() can
+block if there isn't enough space in the journal for your transaction
+(based on the passed nblocks param) - when it blocks it merely(!) needs to
+wait for transactions to complete and be committed from other tasks,
+so essentially we are waiting for journal_stop(). So to avoid
+deadlocks you must treat journal_start/stop() as if they
+were semaphores and include them in your semaphore ordering rules to prevent
+deadlocks. Note that journal_extend() has similar blocking behaviour to
+journal_start() so you can deadlock here just as easily as on journal_start().
+</para>
+
+<para>
+Try to reserve the right number of blocks the first time. ;-). This will
+be the maximum number of blocks you are going to touch in this transaction.
+I advise having a look at at least ext3_jbd.h to see the basis on which
+ext3 uses to make these decisions.
+</para>
+
+<para>
+Another wriggle to watch out for is your on-disk block allocation strategy.
+why? Because, if you undo a delete, you need to ensure you haven't reused any
+of the freed blocks in a later transaction. One simple way of doing this
+is make sure any blocks you allocate only have checkpointed transactions
+listed against them. Ext3 does this in ext3_test_allocatable().
+</para>
+
+<para>
+Lock is also providing through journal_{un,}lock_updates(),
+ext3 uses this when it wants a window with a clean and stable fs for a moment.
+eg.
+</para>
+
+<programlisting>
+
+ journal_lock_updates() //stop new stuff happening..
+ journal_flush() // checkpoint everything.
+ ..do stuff on stable fs
+ journal_unlock_updates() // carry on with filesystem use.
+</programlisting>
+
+<para>
+The opportunities for abuse and DOS attacks with this should be obvious,
+if you allow unprivileged userspace to trigger codepaths containing these
+calls.
+</para>
+
+<para>
+A new feature of jbd since 2.5.25 is commit callbacks with the new
+journal_callback_set() function you can now ask the journalling layer
+to call you back when the transaction is finally committed to disk, so that
+you can do some of your own management. The key to this is the journal_callback
+struct, this maintains the internal callback information but you can
+extend it like this:-
+</para>
+<programlisting>
+ struct myfs_callback_s {
+ //Data structure element required by jbd..
+ struct journal_callback for_jbd;
+ // Stuff for myfs allocated together.
+ myfs_inode* i_commited;
+
+ }
+</programlisting>
+
+<para>
+this would be useful if you needed to know when data was committed to a
+particular inode.
+</para>
+

+
+ <sect2>
+ <title>Summary</title>
+<para>
+Using the journal is a matter of wrapping the different context changes,
+being each mount, each modification (transaction) and each changed buffer
+to tell the journalling layer about them.

+
+ <sect1>
+ <title>Data Types</title>
+ <para>
+ The journalling layer uses typedefs to 'hide' the concrete definitions
+ of the structures used. As a client of the JBD layer you can
+ just rely on the using the pointer as a magic cookie of some sort.
+
+ Obviously the hiding is not enforced as this is 'C'.

PORTING GUIDE
If the answer is no, you need a timer to provide the timer interrupt
at 100 HZ speed.
- You cannot use the fast gettimeoffset functions, i.e.,
-
- unsigned long fixed_rate_gettimeoffset(void);
- unsigned long calibrate_div32_gettimeoffset(void);
- unsigned long calibrate_div64_gettimeoffset(void);
-
- You can use null_gettimeoffset() will gives the same time resolution as
- jiffy. Or you can implement your own gettimeoffset (probably based on
- some ad hoc hardware on your machine.)
-
c) The following sub steps assume your CPU has counter register.
Do you plan to use the CPU counter register as the timer interrupt
or use an exnternal timer?
In order to use CPU counter register as the timer interrupt source, you
- must know the counter speed (mips_counter_frequency). It is usually the
+ must know the counter speed (mips_hpt_frequency). It is usually the
same as the CPU speed or an integral divisor of it.
d) decide on whether you want to use high-level or low-level timer
if needed.
board_time_init() -
- a) (optional) set up RTC routines,
- b) (optional) calibrate and set the mips_counter_frequency
- (only needed if you intended to use fixed_rate_gettimeoffset
- or use cpu counter as timer interrupt source)

plat_timer_setup() -
a) (optional) over-write any choices made above by time_init().
For example, you may define your own timer interrupt routine, which does
some of its own processing and then calls timer_interrupt().
-You can also over-ride any of the built-in functions (gettimeoffset,
-RTC routines and/or timer interrupt routine).
+You can also over-ride any of the built-in functions (RTC routines
+and/or timer interrupt routine).
PORTING NOTES FOR SMP
You can also do the low-level version of those interrupt routines,
following similar dispatching routes described above.
-
-Note about do_gettimeoffset():
-
- It is very likely the CPU counter registers are not sync'ed up in a SMP box.
- Therefore you cannot really use the many of the existing routines that
- are based on CPU counter. You should wirte your own gettimeoffset rouinte
- if you want intra-jiffy resolution.
that is known a priori. But, the user may choose 'shutdown' or
'reboot' as alternatives.
+Additionally, /sys/power/disk can be used to turn on one of the two testing
+modes of the suspend-to-disk mechanism: 'testproc' or 'test'. If the
+suspend-to-disk mechanism is in the 'testproc' mode, writing 'disk' to
+/sys/power/state will cause the kernel to disable nonboot CPUs and freeze
+tasks, wait for 5 seconds, unfreeze tasks and enable nonboot CPUs. If it is
+in the 'test' mode, writing 'disk' to /sys/power/state will cause the kernel
+to disable nonboot CPUs and freeze tasks, shrink memory, suspend devices, wait
+for 5 seconds, resume devices, unfreeze tasks and enable nonboot CPUs. Then,
+we are able to look in the log messages and work out, for example, which code
+is being slow and which device drivers are misbehaving.
+
Reading from this file will display what the mode is currently set
to. Writing to this file will accept one of
'platform'
'shutdown'
'reboot'
+ 'testproc'
+ 'test'
It will only change to 'firmware' or 'platform' if the system supports
it.
- Real Time Clock Driver for Linux
- ================================
+ Real Time Clock (RTC) Drivers for Linux
+ =======================================
+
+When Linux developers talk about a "Real Time Clock", they usually mean
+something that tracks wall clock time and is battery backed so that it
+works even with system power off. Such clocks will normally not track
+the local time zone or daylight savings time -- unless they dual boot
+with MS-Windows -- but will instead be set to Coordinated Universal Time
+(UTC, formerly "Greenwich Mean Time").
+
+The newest non-PC hardware tends to just count seconds, like the time(2)
+system call reports, but RTCs also very commonly represent time using
+the Gregorian calendar and 24 hour time, as reported by gmtime(3).
+
+Linux has two largely-compatible userspace RTC API families you may
+need to know about:
+
+ * /dev/rtc ... is the RTC provided by PC compatible systems,
+ so it's not very portable to non-x86 systems.
+
+ * /dev/rtc0, /dev/rtc1 ... are part of a framework that's
+ supported by a wide variety of RTC chips on all systems.
+
+Programmers need to understand that the PC/AT functionality is not
+always available, and some systems can do much more. That is, the
+RTCs use the same API to make requests in both RTC frameworks (using
+different filenames of course), but the hardware may not offer the
+same functionality. For example, not every RTC is hooked up to an
+IRQ, so they can't all issue alarms; and where standard PC RTCs can
+only issue an alarm up to 24 hours in the future, other hardware may
+be able to schedule one any time in the upcoming century.
+
+
+ Old PC/AT-Compatible driver: /dev/rtc
+ --------------------------------------
All PCs (even Alpha machines) have a Real Time Clock built into them.
Usually they are built into the chipset of the computer, but some may
actually have a Motorola MC146818 (or clone) on the board. This is the
clock that keeps the date and time while your computer is turned off.
+ACPI has standardized that MC146818 functionality, and extended it in
+a few ways (enabling longer alarm periods, and wake-from-hibernate).
+That functionality is NOT exposed in the old driver.
+
However it can also be used to generate signals from a slow 2Hz to a
relatively fast 8192Hz, in increments of powers of two. These signals
are reported by interrupt number 8. (Oh! So *that* is what IRQ 8 is
perhaps more useful to include a small test program that demonstrates
how to use them, and demonstrates the features of the driver. This is
probably a lot more useful to people interested in writing applications
-that will be using this driver.
+that will be using this driver. See the code at the end of this document.
+
+(The original /dev/rtc driver was written by Paul Gortmaker.)
+
+
+ New portable "RTC Class" drivers: /dev/rtcN
+ --------------------------------------------
+
+Because Linux supports many non-ACPI and non-PC platforms, some of which
+have more than one RTC style clock, it needed a more portable solution
+than expecting a single battery-backed MC146818 clone on every system.
+Accordingly, a new "RTC Class" framework has been defined. It offers
+three different userspace interfaces:
+
+ * /dev/rtcN ... much the same as the older /dev/rtc interface
+
+ * /sys/class/rtc/rtcN ... sysfs attributes support readonly
+ access to some RTC attributes.
+
+ * /proc/driver/rtc ... the first RTC (rtc0) may expose itself
+ using a procfs interface. More information is (currently) shown
+ here than through sysfs.
+
+The RTC Class framework supports a wide variety of RTCs, ranging from those
+integrated into embeddable system-on-chip (SOC) processors to discrete chips
+using I2C, SPI, or some other bus to communicate with the host CPU. There's
+even support for PC-style RTCs ... including the features exposed on newer PCs
+through ACPI.
+
+The new framework also removes the "one RTC per system" restriction. For
+example, maybe the low-power battery-backed RTC is a discrete I2C chip, but
+a high functionality RTC is integrated into the SOC. That system might read
+the system clock from the discrete RTC, but use the integrated one for all
+other tasks, because of its greater functionality.
+
+The ioctl() calls supported by /dev/rtc are also supported by the RTC class
+framework. However, because the chips and systems are not standardized,
+some PC/AT functionality might not be provided. And in the same way, some
+newer features -- including those enabled by ACPI -- are exposed by the
+RTC class framework, but can't be supported by the older driver.
+
+ * RTC_RD_TIME, RTC_SET_TIME ... every RTC supports at least reading
+ time, returning the result as a Gregorian calendar date and 24 hour
+ wall clock time. To be most useful, this time may also be updated.
+
+ * RTC_AIE_ON, RTC_AIE_OFF, RTC_ALM_SET, RTC_ALM_READ ... when the RTC
+ is connected to an IRQ line, it can often issue an alarm IRQ up to
+ 24 hours in the future.
+
+ * RTC_WKALM_SET, RTC_WKALM_READ ... RTCs that can issue alarms beyond
+ the next 24 hours use a slightly more powerful API, which supports
+ setting the longer alarm time and enabling its IRQ using a single
+ request (using the same model as EFI firmware).
+
+ * RTC_UIE_ON, RTC_UIE_OFF ... if the RTC offers IRQs, it probably
+ also offers update IRQs whenever the "seconds" counter changes.
+ If needed, the RTC framework can emulate this mechanism.
+
+ * RTC_PIE_ON, RTC_PIE_OFF, RTC_IRQP_SET, RTC_IRQP_READ ... another
+ feature often accessible with an IRQ line is a periodic IRQ, issued
+ at settable frequencies (usually 2^N Hz).
+
+In many cases, the RTC alarm can be a system wake event, used to force
+Linux out of a low power sleep state (or hibernation) back to a fully
+operational state. For example, a system could enter a deep power saving
+state until it's time to execute some scheduled tasks.

-AIRcable USB Dongle Bluetooth driver
- If there is the cdc_acm driver loaded in the system, you will find that the
- cdc_acm claims the device before AIRcable can. This is simply corrected
- by unloading both modules and then loading the aircable module before
- cdc_acm module

-/*
- * Changelog
- * ~~~~~~~~~
- *
- * Thu, 22 Aug 2002 15:10:43 +0200
- * - Update Config.help entry. I got a number of emails asking
- * me to tell their senders if they could make use of this
- * piece of code... So: "SRM is something like BIOS for your
- * Alpha"
- * - Update code formatting a bit to better conform CodingStyle
- * rules.
- * - So this is v0.0.5, with no changes (except formatting)
- *
- * Wed, 22 May 2002 00:11:21 +0200
- * - Fix typo on comment (SRC -> SRM)
- * - Call this "Version 0.0.4"
- *
- * Tue, 9 Apr 2002 18:44:40 +0200
- * - Implement access by variable name and additionally
- * by number. This is done by creating two subdirectories
- * where one holds all names (like the old directory
- * did) and the other holding 256 files named like "0",
- * "1" and so on.
- * - Call this "Version 0.0.3"

+ *
+ * History:
+ * 2003 - Created version 1.0 for Linux 2.4.x.
+ * 2006 - Ported to Linux 2.6, added nowayout and MAGICCLOSE
+ * features. Released version 1.1
+ *
+ * Theory of operation:
+ *
+ * A Watchdog Timer (WDT) is a hardware circuit that can
+ * reset the computer system in case of a software fault.
+ * You probably knew that already.
+ *
+ * Usually a userspace daemon will notify the kernel WDT driver
+ * via the /dev/watchdog special device file that userspace is
+ * still alive, at regular intervals. When such a notification
+ * occurs, the driver will usually tell the hardware watchdog
+ * that everything is in order, and that the watchdog should wait
+ * for yet another little while to reset the system.
+ * If userspace fails (RAM error, kernel bug, whatever), the
+ * notifications cease to occur, and the hardware watchdog will
+ * reset the system (causing a reboot) after the timeout occurs.
+ *
+ * Create device with:
+ * mknod /dev/watchdog c 10 130
+ *
+ * For an example userspace keep-alive daemon, see:
+ * Documentation/watchdog/watchdog.txt

Version 1.46
------------
Support deep tree mounts. Better support OS/2, Win9x (DOS) time stamps.
+Allow null user to be specified on mount ("username="). Do not return
+EINVAL on readdir when filldir fails due to overwritten blocksize
+(fixes FC problem). Return error in rename 2nd attempt retry (ie report
+if rename by handle also fails, after rename by path fails, we were
+not reporting whether the retry worked or not).

---help---
- Enable the deprecated sysctl system call. sys_sysctl uses
- binary paths that have been found to be a major pain to maintain
- and use. The interface in /proc/sys is now the primary and what
- everyone uses.
+ sys_sysctl uses binary paths that have been found challenging
+ to properly maintain and use. The interface in /proc/sys
+ using paths with ascii names is now the primary path to this
+ information.
- Nothing has been using the binary sysctl interface for some
- time now so nothing should break if you disable sysctl syscall
- support, and your kernel will get marginally smaller.
+ Almost nothing using the binary sysctl interface so if you are
+ trying to save some space it is probably safe to disable this,
+ making your kernel marginally smaller.
- Unless you have an application that uses the sys_sysctl interface
- you should probably say N here.
+ If unsure say Y here.
