RCU Torture Test Operation
CONFIG_RCU_TORTURE_TEST
The CONFIG_RCU_TORTURE_TEST config option is available for all RCU
implementations. It creates an rcutorture kernel module that can
be loaded to run a torture test. The test periodically outputs
status messages via printk(), which can be examined via the dmesg
command (perhaps grepping for "rcutorture"). The test is started
when the module is loaded, and stops when the module is unloaded.
However, actually setting this config option to "y" results in the system
running the test immediately upon boot, and ending only when the system
is taken down. Normally, one will instead want to build the system
with CONFIG_RCU_TORTURE_TEST=m and to use modprobe and rmmod to control
the test, perhaps using a script similar to the one shown at the end of
this document. Note that you will need CONFIG_MODULE_UNLOAD in order
to be able to end the test.
MODULE PARAMETERS
This module has the following parameters:
nreaders This is the number of RCU reading threads supported.
The default is twice the number of CPUs. Why twice?
To properly exercise RCU implementations with preemptible
read-side critical sections.
stat_interval The number of seconds between output of torture
statistics (via printk()). Regardless of the interval,
statistics are printed when the module is unloaded.
Setting the interval to zero causes the statistics to
be printed -only- when the module is unloaded, and this
is the default.
verbose Enable debug printk()s. Default is disabled.
OUTPUT
The statistics output is as follows:
rcutorture: --- Start of test: nreaders=16 stat_interval=0 verbose=0
rcutorture: rtc: 0000000000000000 ver: 1916 tfle: 0 rta: 1916 rtaf: 0 rtf: 1915
rcutorture: Reader Pipe: 1466408 9747 0 0 0 0 0 0 0 0 0
rcutorture: Reader Batch: 1464477 11678 0 0 0 0 0 0 0 0
rcutorture: Free-Block Circulation: 1915 1915 1915 1915 1915 1915 1915 1915 1915 1915 0
rcutorture: --- End of test
The command "dmesg | grep rcutorture:" will extract this information on
most systems. On more esoteric configurations, it may be necessary to
use other commands to access the output of the printk()s used by
the RCU torture test. The printk()s use KERN_ALERT, so they should
be evident. ;-)
The entries are as follows:
o "ggp": The number of counter flips (or batches) since boot.
o "rtc": The hexadecimal address of the structure currently visible
to readers.
o "ver": The number of times since boot that the rcutw writer task
has changed the structure visible to readers.
o "tfle": If non-zero, indicates that the "torture freelist"
containing structure to be placed into the "rtc" area is empty.
This condition is important, since it can fool you into thinking
that RCU is working when it is not. :-/
o "rta": Number of structures allocated from the torture freelist.
o "rtaf": Number of allocations from the torture freelist that have
failed due to the list being empty.
o "rtf": Number of frees into the torture freelist.
o "Reader Pipe": Histogram of "ages" of structures seen by readers.
If any entries past the first two are non-zero, RCU is broken.
And rcutorture prints the error flag string "!!!" to make sure
you notice. The age of a newly allocated structure is zero,
it becomes one when removed from reader visibility, and is
incremented once per grace period subsequently -- and is freed
after passing through (RCU_TORTURE_PIPE_LEN-2) grace periods.
The output displayed above was taken from a correctly working
RCU. If you want to see what it looks like when broken, break
it yourself. ;-)
o "Reader Batch": Another histogram of "ages" of structures seen
by readers, but in terms of counter flips (or batches) rather
than in terms of grace periods. The legal number of non-zero
entries is again two. The reason for this separate view is
that it is easier to get the third entry to show up in the
"Reader Batch" list than in the "Reader Pipe" list.
o "Free-Block Circulation": Shows the number of torture structures
that have reached a given point in the pipeline. The first element
should closely correspond to the number of structures allocated,
the second to the number that have been removed from reader view,
and all but the last remaining to the corresponding number of
passes through a grace period. The last entry should be zero,
as it is only incremented if a torture structure's counter
somehow gets incremented farther than it should.
USAGE
The following script may be used to torture RCU:
#!/bin/sh
modprobe rcutorture
sleep 100
rmmod rcutorture
dmesg | grep rcutorture:
The output can be manually inspected for the error flag of "!!!".
One could of course create a more elaborate script that automatically
checked for such errors.

4. The I/O scheduler
I/O schedulers are now per queue. They should be runtime switchable and modular
but aren't yet. Jens has most bits to do this, but the sysfs implementation is
missing.
I/O scheduler, a.k.a. elevator, is implemented in two layers. Generic dispatch
queue and specific I/O schedulers. Unless stated otherwise, elevator is used
to refer to both parts and I/O scheduler to specific I/O schedulers.
Block layer implements generic dispatch queue in ll_rw_blk.c and elevator.c.
The generic dispatch queue is responsible for properly ordering barrier
requests, requeueing, handling non-fs requests and all other subtleties.
Specific I/O schedulers are responsible for ordering normal filesystem
requests. They can also choose to delay certain requests to improve
throughput or whatever purpose. As the plural form indicates, there are
multiple I/O schedulers. They can be built as modules but at least one should
be built inside the kernel. Each queue can choose different one and can also
change to another one dynamically.
A block layer call to the i/o scheduler follows the convention elv_xxx(). This
calls elevator_xxx_fn in the elevator switch (drivers/block/elevator.c). Oh,

This arrangement is not a generic block layer characteristic however, so
elevators may implement queues as they please.
ii. Last merge hint
The last merge hint is part of the generic queue layer. I/O schedulers must do
some management on it. For the most part, the most important thing is to make
sure q->last_merge is cleared (set to NULL) when the request on it is no longer
a candidate for merging (for example if it has been sent to the driver).
The last merge performed is cached as a hint for the subsequent request. If
sequential data is being submitted, the hint is used to perform merges without
any scanning. This is not sufficient when there are multiple processes doing
I/O though, so a "merge hash" is used by some schedulers.

are far less common than "back merges" due to the nature of most I/O patterns.
Front merges are handled by the binary trees in AS and deadline schedulers.
iv. Handling barrier cases
A request with flags REQ_HARDBARRIER or REQ_SOFTBARRIER must not be ordered
around. That is, they must be processed after all older requests, and before
any newer ones. This includes merges!
In AS and deadline schedulers, barriers have the effect of flushing the reorder
queue. The performance cost of this will vary from nothing to a lot depending
on i/o patterns and device characteristics. Obviously they won't improve
performance, so their use should be kept to a minimum.
v. Handling insertion position directives
A request may be inserted with a position directive. The directives are one of
ELEVATOR_INSERT_BACK, ELEVATOR_INSERT_FRONT, ELEVATOR_INSERT_SORT.
ELEVATOR_INSERT_SORT is a general directive for non-barrier requests.
ELEVATOR_INSERT_BACK is used to insert a barrier to the back of the queue.
ELEVATOR_INSERT_FRONT is used to insert a barrier to the front of the queue, and
overrides the ordering requested by any previous barriers. In practice this is
harmless and required, because it is used for SCSI requeueing. This does not
require flushing the reorder queue, so does not impose a performance penalty.

int (*suspend) (struct device * dev, pm_message_t state);
suspend is called to put the device in a low power state. There are
several stages to successfully suspending a device, which is denoted in
the @level parameter. Breaking the suspend transition into several
stages affords the platform flexibility in performing device power
management based on the requirements of the system and the
user-defined policy.
suspend is called to put the device in a low power state.
SUSPEND_NOTIFY notifies the device that a suspend transition is about
to happen. This happens on system power state transitions to verify
that all devices can successfully suspend.
int (*resume) (struct device * dev);
A driver may choose to fail on this call, which should cause the
entire suspend transition to fail. A driver should fail only if it
knows that the device will not be able to be resumed properly when the
system wakes up again. It could also fail if it somehow determines it
is in the middle of an operation too important to stop.
SUSPEND_DISABLE tells the device to stop I/O transactions. When it
stops transactions, or what it should do with unfinished transactions
is a policy of the driver. After this call, the driver should not
accept any other I/O requests.
SUSPEND_SAVE_STATE tells the device to save the context of the
hardware. This includes any bus-specific hardware state and
device-specific hardware state. A pointer to this saved state can be
stored in the device's saved_state field.
SUSPEND_POWER_DOWN tells the driver to place the device in the low
power state requested.
Whether suspend is called with a given level is a policy of the
platform. Some levels may be omitted; drivers must not assume the
reception of any level. However, all levels must be called in the
order above; i.e. notification will always come before disabling;
disabling the device will come before suspending the device.
All calls are made with interrupts enabled, except for the
SUSPEND_POWER_DOWN level.
int (*resume) (struct device * dev, u32 level);
Resume is used to bring a device back from a low power state. Like the
suspend transition, it happens in several stages.
RESUME_POWER_ON tells the driver to set the power state to the state
before the suspend call (The device could have already been in a low
power state before the suspend call to put in a lower power state).
RESUME_RESTORE_STATE tells the driver to restore the state saved by
the SUSPEND_SAVE_STATE suspend call.
RESUME_ENABLE tells the driver to start accepting I/O transactions
again. Depending on driver policy, the device may already have pending
I/O requests.
RESUME_POWER_ON is called with interrupts disabled. The other resume
levels are called with interrupts enabled.
As with the various suspend stages, the driver must not assume that
any other resume calls have been or will be made. Each call should be
self-contained and not dependent on any external state.

- Write support is now extended with write(2) being able to both
overwrite existing file data and to extend files. Also, if a write
to a sparse region occurs, write(2) will fill in the hole. Note,
mmap(2) based writes still do not support writing into holes or
writing beyond the initialized size.
- Write support has a new feature and that is that truncate(2) and
open(2) with O_TRUNC are now implemented thus files can be both made
smaller and larger.
- Note: Both write(2) and truncate(2)/open(2) with O_TRUNC still have
limitations in that they
- only provide limited support for highly fragmented files.
- only work on regular, i.e. uncompressed and unencrypted files.
- never create sparse files although this will change once directory
operations are implemented.
- Lots of bug fixes and enhancements across the board.
2.1.24:
- Support journals ($LogFile) which have been modified by chkdsk. This
means users can boot into Windows after we marked the volume dirty.

Byte), the ADM1032 computes the CRC value over only the second half of
the message rather than its entirety, because it thinks the first half
of the message belongs to a different transaction. As a result, the CRC
value differs from what the SMBus master expects, and all reads fail.
For this reason, the lm90 driver will enable PEC for the ADM1032 only if
the bus supports the SMBus Send Byte and Receive Byte transaction types.
These transactions will be used to read register values, instead of
SMBus Read Byte, and PEC will work properly.
Additionally, the ADM1032 doesn't support SMBus Send Byte with PEC.
Instead, it will try to write the PEC value to the register (because the
SMBus Send Byte transaction with PEC is similar to a Write Byte transaction
without PEC), which is not what we want. Thus, PEC is explicitely disabled
on SMBus Send Byte transactions in the lm90 driver.
PEC on byte data transactions represents a significant increase in bandwidth
usage (+33% for writes, +25% for reads) in normal conditions. With the need
to use two SMBus transaction for reads, this overhead jumps to +50%. Worse,
two transactions will typically mean twice as much delay waiting for
transaction completion, effectively doubling the register cache refresh time.
I guess reliability comes at a price, but it's quite expensive this time.
So, as not everyone might enjoy the slowdown, PEC can be disabled through
sysfs. Just write 0 to the "pec" file and PEC will be disabled. Write 1
to that file to enable PEC again.

Known Issues
------------
This driver handles sensors integrated in some VIA south bridges. It is
possible that a motherboard maker used a VT82C686A/B chip as part of a
product design but was not interested in its hardware monitoring features,
in which case the sensor inputs will not be wired. This is the case of
the Asus K7V, A7V and A7V133 motherboards, to name only a few of them.
So, if you need the force_addr parameter, and end up with values which
don't seem to make any sense, don't look any further: your chip is simply
not wired for hardware monitoring.

Kernel driver x1205
===================
Supported chips:
* Xicor X1205 RTC
Prefix: 'x1205'
Addresses scanned: none
Datasheet: http://www.intersil.com/cda/deviceinfo/0,1477,X1205,00.html
Authors:
Karen Spearel <kas11@tampabay.rr.com>,
Alessandro Zummo <a.zummo@towertech.it>
Description
-----------
This module aims to provide complete access to the Xicor X1205 RTC.
Recently Xicor has merged with Intersil, but the chip is
still sold under the Xicor brand.
This chip is located at address 0x6f and uses a 2-byte register addressing.
Two bytes need to be written to read a single register, while most
other chips just require one and take the second one as the data
to be written. To prevent corrupting unknown chips, the user must
explicitely set the probe parameter.
example:
modprobe x1205 probe=0,0x6f
The module supports one more option, hctosys, which is used to set the
software clock from the x1205. On systems where the x1205 is the
only hardware rtc, this parameter could be used to achieve a correct
date/time earlier in the system boot sequence.
example:
modprobe x1205 probe=0,0x6f hctosys=1

4.5) stram_swap=
----------------
Syntax: stram_swap=<do_swap>[,<max_swap>]
This option is available only if the kernel has been compiled with
CONFIG_STRAM_SWAP enabled. Normally, the kernel then determines
dynamically whether to actually use ST-RAM as swap space. (Currently,
the fraction of ST-RAM must be less or equal 1/3 of total memory to
enable this swapping.) You can override the kernel's decision by
specifying this option. 1 for <do_swap> means always enable the swap,
even if you have less alternate RAM. 0 stands for never swap to
ST-RAM, even if it's small enough compared to the rest of memory.
If ST-RAM swapping is enabled, the kernel usually uses all free
ST-RAM as swap "device". If the kernel resides in ST-RAM, the region
allocated by it is obviously never used for swapping :-) You can also
limit this amount by specifying the second parameter, <max_swap>, if
you want to use parts of ST-RAM as normal system memory. <max_swap> is
in kBytes and the number should be a multiple of 4 (otherwise: rounded
down).

README for MIPS AU1XXX IDE driver - Released 2005-07-15
ABOUT
-----
This file describes the 'drivers/ide/mips/au1xxx-ide.c', related files and the
services they provide.
If you are short in patience and just want to know how to add your hard disc to
the white or black list, go to the 'ADD NEW HARD DISC TO WHITE OR BLACK LIST'
section.

Interface and Linux Device Driver" Application Note.
FILES, CONFIGS AND COMPATABILITY
--------------------------------
Two files are introduced:
a) 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
containes : struct _auide_hwif
struct drive_list_entry dma_white_list
struct drive_list_entry dma_black_list
timing parameters for PIO mode 0/1/2/3/4
timing parameters for MWDMA 0/1/2
b) 'drivers/ide/mips/au1xxx-ide.c'
contains the functionality of the AU1XXX IDE driver
Four configs variables are introduced:
CONFIG_BLK_DEV_IDE_AU1XXX_PIO_DBDMA - enable the PIO+DBDMA mode
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA - enable the MWDMA mode
CONFIG_BLK_DEV_IDE_AU1XXX_BURSTABLE_ON - set Burstable FIFO in DBDMA
controler
CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ - maximum transfer size
per descriptor
If MWDMA is enabled and the connected hard disc is not on the white list, the
kernel switches to a "safe mwdma mode" at boot time. In this mode the IDE
performance is substantial slower then in full speed mwdma. In this case
please add your hard disc to the white list (follow instruction from 'ADD NEW
HARD DISC TO WHITE OR BLACK LIST' section).
SUPPORTED IDE MODES
-------------------
The AU1XXX IDE driver supported all PIO modes - PIO mode 0/1/2/3/4 - and all
MWDMA modes - MWDMA 0/1/2 -. There is no support for SWDMA and UDMA mode.
To change the PIO mode use the program hdparm with option -p, e.g.
'hdparm -p0 [device]' for PIO mode 0. To enable the MWDMA mode use the option
-X, e.g. 'hdparm -X32 [device]' for MWDMA mode 0.
PERFORMANCE CONFIGURATIONS
--------------------------
If the used system doesn't need USB support enable the following kernel configs:
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDE_AU1XXX=y
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
CONFIG_BLK_DEV_IDE_AU1XXX_BURSTABLE_ON=y
CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
If the used system need the USB support enable the following kernel configs for
high IDE to USB throughput.
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_IDEDMA_PCI_AUTO=y
CONFIG_BLK_DEV_IDE_AU1XXX=y
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
CONFIG_BLK_DEV_IDE_AU1XXX_SEQTS_PER_RQ=128
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y
ADD NEW HARD DISC TO WHITE OR BLACK LIST
----------------------------------------
Step 1 : detect the model name of your hard disc
a) connect your hard disc to the AU1XXX
b) boot your kernel and get the hard disc model.
Example boot log:
--snipped--
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx
Au1xxx IDE(builtin) configured for MWDMA2
Probing IDE interface ide0...
hda: Maxtor 6E040L0, ATA DISK drive
ide0 at 0xac800000-0xac800007,0xac8001c0 on irq 64

hda: 80293248 sectors (41110 MB) w/2048KiB Cache, CHS=65535/16/63, (U)DMA
--snipped--
In this example 'Maxtor 6E040L0'.
Step 2 : edit 'include/asm-mips/mach-au1x00/au1xxx_ide.h'
Add your hard disc to the dma_white_list or dma_black_list structur.
Step 3 : Recompile the kernel
Enable MWDMA support in the kernel configuration. Recompile the kernel and
reboot.
Step 4 : Tests
If you have add a hard disc to the white list, please run some stress tests
for verification.
