KernelVersion: 2.6.38

Description:
Value representing the can_id of mailbox 0.
Default: 0x7ff (standard frame)
Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
"AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the
contents of mailbox 0 may be send under certain
conditions (even if disabled or in rx mode).
The workaround in the errata suggests not to use the
mailbox and load it with an unused identifier.
In order to use an extended can_id add the
CAN_EFF_FLAG (0x80000000U) to the can_id. Example:
- standard id 0x7ff:
echo 0x7ff > /sys/class/net/can0/mb0_id
- extended id 0x1fffffff:
echo 0x9fffffff > /sys/class/net/can0/mb0_id

------------
Get the detailed info related with the IPMI device
--------------------------------------------------
Some users need more detailed information about a device, like where
the address came from or the raw base device for the IPMI interface.
You can use the IPMI smi_watcher to catch the IPMI interfaces as they
come or go, and to grab the information, you can use the function
ipmi_get_smi_info(), which returns the following structure:
struct ipmi_smi_info {
enum ipmi_addr_src addr_src;
struct device *dev;
union {
struct {
void *acpi_handle;
} acpi_info;
} addr_info;
};
Currently special info for only for SI_ACPI address sources is
returned. Others may be added as necessary.
Note that the dev pointer is included in the above structure, and
assuming ipmi_smi_get_info returns success, you must call put_device
on the dev pointer.

CONFIG_TINY_RCU and CONFIG_TINY_PREEMPT_RCU debugfs Files and Formats
These implementations of RCU provides a single debugfs file under the
top-level directory RCU, namely rcu/rcudata, which displays fields in
rcu_bh_ctrlblk, rcu_sched_ctrlblk and, for CONFIG_TINY_PREEMPT_RCU,
rcu_preempt_ctrlblk.
The output of "cat rcu/rcudata" is as follows:
rcu_preempt: qlen=24 gp=1097669 g197/p197/c197 tasks=...
ttb=. btg=no ntb=184 neb=0 nnb=183 j=01f7 bt=0274
normal balk: nt=1097669 gt=0 bt=371 b=0 ny=25073378 nos=0
exp balk: bt=0 nos=0
rcu_sched: qlen: 0
rcu_bh: qlen: 0
This is split into rcu_preempt, rcu_sched, and rcu_bh sections, with the
rcu_preempt section appearing only in CONFIG_TINY_PREEMPT_RCU builds.
The last three lines of the rcu_preempt section appear only in
CONFIG_RCU_BOOST kernel builds. The fields are as follows:
o "qlen" is the number of RCU callbacks currently waiting either
for an RCU grace period or waiting to be invoked. This is the
only field present for rcu_sched and rcu_bh, due to the
short-circuiting of grace period in those two cases.
o "gp" is the number of grace periods that have completed.
o "g197/p197/c197" displays the grace-period state, with the
"g" number being the number of grace periods that have started
(mod 256), the "p" number being the number of grace periods
that the CPU has responded to (also mod 256), and the "c"
number being the number of grace periods that have completed
(once again mode 256).
Why have both "gp" and "g"? Because the data flowing into
"gp" is only present in a CONFIG_RCU_TRACE kernel.
o "tasks" is a set of bits. The first bit is "T" if there are
currently tasks that have recently blocked within an RCU
read-side critical section, the second bit is "N" if any of the
aforementioned tasks are blocking the current RCU grace period,
and the third bit is "E" if any of the aforementioned tasks are
blocking the current expedited grace period. Each bit is "."
if the corresponding condition does not hold.
o "ttb" is a single bit. It is "B" if any of the blocked tasks
need to be priority boosted and "." otherwise.
o "btg" indicates whether boosting has been carried out during
the current grace period, with "exp" indicating that boosting
is in progress for an expedited grace period, "no" indicating
that boosting has not yet started for a normal grace period,
"begun" indicating that boosting has bebug for a normal grace
period, and "done" indicating that boosting has completed for
a normal grace period.
o "ntb" is the total number of tasks subjected to RCU priority boosting
periods since boot.
o "neb" is the number of expedited grace periods that have had
to resort to RCU priority boosting since boot.
o "nnb" is the number of normal grace periods that have had
to resort to RCU priority boosting since boot.
o "j" is the low-order 12 bits of the jiffies counter in hexadecimal.
o "bt" is the low-order 12 bits of the value that the jiffies counter
will have at the next time that boosting is scheduled to begin.
o In the line beginning with "normal balk", the fields are as follows:
o "nt" is the number of times that the system balked from
boosting because there were no blocked tasks to boost.
Note that the system will balk from boosting even if the
grace period is overdue when the currently running task
is looping within an RCU read-side critical section.
There is no point in boosting in this case, because
boosting a running task won't make it run any faster.

The boot loader must load a device tree image (dtb) into system ram

Customizing OPP for platform
============================
Defining CONFIG_PM should enable OPP layer for the silicon
and the registration of OPP table should take place automatically.
However, in special cases, the default OPP table may need to be
tweaked, for e.g.:
* enable default OPPs which are disabled by default, but which
could be enabled on a platform
* Disable an unsupported OPP on the platform
* Define and add a custom opp table entry
in these cases, the board file needs to do additional steps as follows:
arch/arm/mach-omapx/board-xyz.c
#include "pm.h"

static void __init omap_xyz_init_irq(void)

/* Initialize the default table */
omapx_opp_init();
/* Do customization to the defaults */

Software emulation of deprecated SWP instruction (CONFIG_SWP_EMULATE)
---------------------------------------------------------------------
ARMv6 architecture deprecates use of the SWP/SWPB instructions, and recommeds
moving to the load-locked/store-conditional instructions LDREX and STREX.
ARMv7 multiprocessing extensions introduce the ability to disable these
instructions, triggering an undefined instruction exception when executed.
Trapped instructions are emulated using an LDREX/STREX or LDREXB/STREXB
sequence. If a memory access fault (an abort) occurs, a segmentation fault is
signalled to the triggering process.
/proc/cpu/swp_emulation holds some statistics/information, including the PID of
the last process to trigger the emulation to be invocated. For example:
---
Emulated SWP: 12
Emulated SWPB: 0
Aborted SWP{B}: 1
Last process: 314
---
NOTE: when accessing uncached shared regions, LDREX/STREX rely on an external
transaction monitoring block called a global monitor to maintain update
atomicity. If your system does not implement a global monitor, this option can
cause programs that perform SWP operations to uncached memory to deadlock, as
the STREX operation will always fail.

Hierarchical Cgroups
====================
- Currently none of the IO control policy supports hierarhical groups. But
cgroup interface does allow creation of hierarhical cgroups and internally
IO policies treat them as flat hierarchy.
So this patch will allow creation of cgroup hierarhcy but at the backend
everything will be treated as flat. So if somebody created a hierarchy like
as follows.
root
/ \
test1 test2
|
test3
CFQ and throttling will practically treat all groups at same level.
pivot

Down the line we can implement hierarchical accounting/control support
and also introduce a new cgroup file "use_hierarchy" which will control
whether cgroup hierarchy is viewed as flat or hierarchical by the policy..
This is how memory controller also has implemented the things.

The kernel source tree now contains the drivers/staging/ directory, where
many sub-directories for drivers or filesystems that are on their way to
being added to the kernel tree live. They remain in drivers/staging while
they still need more work; once complete, they can be moved into the
kernel proper. This is a way to keep track of drivers that aren't
up to Linux kernel coding or quality standards, but people may want to use
them and track development.
Greg Kroah-Hartman currently (as of 2.6.36) maintains the staging tree.
Drivers that still need work are sent to him, with each driver having
its own subdirectory in drivers/staging/. Along with the driver source
files, a TODO file should be present in the directory as well. The TODO
file lists the pending work that the driver needs for acceptance into
the kernel proper, as well as a list of people that should be Cc'd for any
patches to the driver. Staging drivers that don't currently build should
have their config entries depend upon CONFIG_BROKEN. Once they can
be successfully built without outside patches, CONFIG_BROKEN can be removed.

Device-mapper RAID (dm-raid) is a bridge from DM to MD. It
provides a way to use device-mapper interfaces to access the MD RAID
drivers.
As with all device-mapper targets, the nominal public interfaces are the
constructor (CTR) tables and the status outputs (both STATUSTYPE_INFO
and STATUSTYPE_TABLE). The CTR table looks like the following:
1: <s> <l> raid \
2: <raid_type> <#raid_params> <raid_params> \
3: <#raid_devs> <meta_dev1> <dev1> .. <meta_devN> <devN>
Line 1 contains the standard first three arguments to any device-mapper
target - the start, length, and target type fields. The target type in
this case is "raid".
Line 2 contains the arguments that define the particular raid
type/personality/level, the required arguments for that raid type, and
any optional arguments. Possible raid types include: raid4, raid5_la,
raid5_ls, raid5_rs, raid6_zr, raid6_nr, and raid6_nc. (raid1 is
planned for the future.) The list of required and optional parameters
is the same for all the current raid types. The required parameters are
positional, while the optional parameters are given as key/value pairs.
The possible parameters are as follows:
<chunk_size> Chunk size in sectors.
[[no]sync] Force/Prevent RAID initialization
[rebuild <idx>] Rebuild the drive indicated by the index
[daemon_sleep <ms>] Time between bitmap daemon work to clear bits
[min_recovery_rate <kB/sec/disk>] Throttle RAID initialization
[max_recovery_rate <kB/sec/disk>] Throttle RAID initialization
[max_write_behind <sectors>] See '-write-behind=' (man mdadm)
[stripe_cache <sectors>] Stripe cache size for higher RAIDs
Line 3 contains the list of devices that compose the array in
metadata/data device pairs. If the metadata is stored separately, a '-'
is given for the metadata device position. If a drive has failed or is
missing at creation time, a '-' can be given for both the metadata and
data drives for a given position.
NB. Currently all metadata devices must be specified as '-'.
Examples:
# RAID4 - 4 data drives, 1 parity
# No metadata devices specified to hold superblock/bitmap info
# Chunk size of 1MiB
# (Lines separated for easy reading)
0 1960893648 raid \
raid4 1 2048 \
5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81
# RAID4 - 4 data drives, 1 parity (no metadata devices)
# Chunk size of 1MiB, force RAID initialization,
# min recovery rate at 20 kiB/sec/disk
0 1960893648 raid \
raid4 4 2048 min_recovery_rate 20 sync\
5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81
Performing a 'dmsetup table' should display the CTR table used to
construct the mapping (with possible reordering of optional
parameters).
Performing a 'dmsetup status' will yield information on the state and
health of the array. The output is as follows:
1: <s> <l> raid \
2: <raid_type> <#devices> <1 health char for each dev> <resync_ratio>
Line 1 is standard DM output. Line 2 is best shown by example:
0 1960893648 raid raid4 5 AAAAA 2/490221568
Here we can see the RAID type is raid4, there are 5 devices - all of
which are 'A'live, and the array is 2/490221568 complete with recovery.

- dcr-reg : < DCR register range >
Optional properties:
- er-offset : All 4xx SoCs with a CPM controller have
one of two different order for the CPM
registers. Some have the CPM registers
in the following order (ER,FR,SR). The
others have them in the following order
(SR,ER,FR). For the second case set
er-offset = <1>.
- unused-units : specifier consist of one cell. For each
bit in the cell, the corresponding bit
in CPM will be set to turn off unused
devices.
- idle-doze : specifier consist of one cell. For each
bit in the cell, the corresponding bit
in CPM will be set to turn off unused
devices. This is usually just CPM[CPU].
- standby : specifier consist of one cell. For each
bit in the cell, the corresponding bit
in CPM will be set on standby and
restored on resume.
- suspend : specifier consist of one cell. For each
bit in the cell, the corresponding bit
in CPM will be set on suspend (mem) and
restored on resume. Note, for standby
and suspend the corresponding bits can
be different or the same. Usually for
standby only class 2 and 3 units are set.
However, the interface does not care.
If they are the same, the additional
power saving will be seeing if support
is available to put the DDR in self
refresh mode and any additional power
saving techniques for the specific SoC.
