Also in 2002, Michael [Michael02b,Michael02a] presented techniques
that defer the destruction of data structures to simplify non-blocking
synchronization (wait-free synchronization, lock-free synchronization,
and obstruction-free synchronization are all examples of non-blocking
synchronization). In particular, this technique eliminates locking,
reduces contention, reduces memory latency for readers, and parallelizes
pipeline stalls and memory latency for writers. However, these
techniques still impose significant read-side overhead in the form of
memory barriers. Researchers at Sun worked along similar lines in the
same timeframe [HerlihyLM02,HerlihyLMS03].

Answer to Quick Quiz
Why does the search function need to return holding the per-entry
lock for this deleted-flag technique to be helpful?
If the search function drops the per-entry lock before returning, then
the caller will be processing stale data in any case. If it is really
OK to be processing stale data, then you don't need a "deleted" flag.
If processing stale data really is a problem, then you need to hold the
per-entry lock across all of the code that uses the value looked up.

Beside functions you can also write documentation for structs, unions,
enums and typedefs. Instead of the function name you must write the name
of the declaration; the struct/union/enum/typedef must always precede
the name. Nesting of declarations is not supported.
Use the argument mechanism to document members or constants.
Inside a struct description, you can use the "private:" and "public:"
comment tags. Structure fields that are inside a "private:" area

The template will have defintions that will be initialised to appropritae values for a specific family of controllers. The template definition has four function pointers. During driver initialisation the function pointers will be set based on the controller family type. This change is done to support new controllers that has different processors and thus different register set.

Zone_reclaim_mode allows to set more or less agressive approaches to

The user can override this setting. It may be beneficial to switch
off zone reclaim if the system is used for a file server and all

It may be beneficial to switch off zone reclaim if the system is
used for a file server and all of memory should be used for caching files
from disk. In that case the caching effect is more important than
data locality.
It may be beneficial to switch this on if one wants to do zone
reclaim regardless of the numa distances in the system.
Allowing zone reclaim to write out pages stops processes that are
writing large amounts of data from dirtying pages on other nodes. Zone
reclaim will write out dirty pages if a zone fills up and so effectively
throttle the process. This may decrease the performance of a single process
since it cannot use all of system memory to buffer the outgoing writes
anymore but it preserve the memory on other nodes so that the performance
of other processes running on other nodes will not be affected.
Allowing regular swap effectively restricts allocations to the local
node unless explicitly overridden by memory policies or cpuset
configurations.
It may be advisable to allow slab reclaim if the system makes heavy
use of files and builds up large slab caches. However, the slab
shrink operation is global, may take a long time and free slabs
in all nodes of the system.
================================================================
zone_reclaim_interval:
The time allowed for off node allocations after zone reclaim
has failed to reclaim enough pages to allow a local allocation.
Time is set in seconds and set by default to 30 seconds.
Reduce the interval if undesired off node allocations occur. However, too
frequent scans will have a negative impact onoff node allocation performance.

4. Overview and features
========================
This driver supports the video interface of the devices mounting the ET61X151
or ET61X251 PC Camera Controllers.
It's worth to note that Etoms Electronics has never collaborated with the
author during the development of this project; despite several requests,
Etoms Electronics also refused to release enough detailed specifications of
the video compression engine.
The driver relies on the Video4Linux2 and USB core modules. It has been
designed to run properly on SMP systems as well.
The latest version of the ET61X[12]51 driver can be found at the following URL:
http://www.linux-projects.org/
Some of the features of the driver are:
- full compliance with the Video4Linux2 API (see also "Notes for V4L2
application developers" paragraph);
- available mmap or read/poll methods for video streaming through isochronous
data transfers;
- automatic detection of image sensor;
- support for any window resolutions and optional panning within the maximum
pixel area of image sensor;
- image downscaling with arbitrary scaling factors from 1 and 2 in both
directions (see "Notes for V4L2 application developers" paragraph);
- two different video formats for uncompressed or compressed data in low or
high compression quality (see also "Notes for V4L2 application developers"
paragraph);
- full support for the capabilities of every possible image sensors that can
be connected to the ET61X[12]51 bridges, including, for istance, red, green,
blue and global gain adjustments and exposure control (see "Supported
devices" paragraph for details);
- use of default color settings for sunlight conditions;
- dynamic I/O interface for both ET61X[12]51 and image sensor control (see
"Optional device control through 'sysfs'" paragraph);
- dynamic driver control thanks to various module parameters (see "Module
parameters" paragraph);
- up to 64 cameras can be handled at the same time; they can be connected and
disconnected from the host many times without turning off the computer, if
the system supports hotplugging;
- no known bugs.
5. Module dependencies
======================
For it to work properly, the driver needs kernel support for Video4Linux and
USB.
The following options of the kernel configuration file must be enabled and
corresponding modules must be compiled:
# Multimedia devices
#
CONFIG_VIDEO_DEV=m
To enable advanced debugging functionality on the device through /sysfs:
# Multimedia devices
#
CONFIG_VIDEO_ADV_DEBUG=y
# USB support
#
CONFIG_USB=m
In addition, depending on the hardware being used, the modules below are
necessary:
# USB Host Controller Drivers
#
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_UHCI_HCD=m
CONFIG_USB_OHCI_HCD=m
And finally:
# USB Multimedia devices
#
CONFIG_USB_ET61X251=m
6. Module loading
=================
To use the driver, it is necessary to load the "et61x251" module into memory
after every other module required: "videodev", "usbcore" and, depending on
the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd".
Loading can be done as shown below:
[root@localhost home]# modprobe et61x251
At this point the devices should be recognized. You can invoke "dmesg" to
analyze kernel messages and verify that the loading process has gone well:
[user@localhost home]$ dmesg
7. Module parameters
====================
Module parameters are listed below:
-------------------------------------------------------------------------------
Name: video_nr
Type: short array (min = 0, max = 64)
Syntax: <-1|n[,...]>
Description: Specify V4L2 minor mode number:
-1 = use next available
n = use minor number n
You can specify up to 64 cameras this way.
For example:
video_nr=-1,2,-1 would assign minor number 2 to the second
registered camera and use auto for the first one and for every
other camera.
Default: -1
-------------------------------------------------------------------------------
Name: force_munmap
Type: bool array (min = 0, max = 64)
Syntax: <0|1[,...]>
Description: Force the application to unmap previously mapped buffer memory
before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not
all the applications support this feature. This parameter is
specific for each detected camera.
0 = do not force memory unmapping
1 = force memory unmapping (save memory)
Default: 0
-------------------------------------------------------------------------------
Name: debug
Type: ushort
Syntax: <n>
Description: Debugging information level, from 0 to 3:
0 = none (use carefully)
1 = critical errors
2 = significant informations
3 = more verbose messages
Level 3 is useful for testing only, when only one device
is used at the same time. It also shows some more informations
about the hardware being detected. This module parameter can be
changed at runtime thanks to the /sys filesystem interface.
Default: 2
-------------------------------------------------------------------------------
8. Optional device control through "sysfs"
==========================================
If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled,
it is possible to read and write both the ET61X[12]51 and the image sensor
registers by using the "sysfs" filesystem interface.
There are four files in the /sys/class/video4linux/videoX directory for each
registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files
control the ET61X[12]51 bridge, while the other two control the sensor chip.
"reg" and "i2c_reg" hold the values of the current register index where the
following reading/writing operations are addressed at through "val" and
"i2c_val". Their use is not intended for end-users, unless you know what you
are doing. Remember that you must be logged in as root before writing to them.
As an example, suppose we were to want to read the value contained in the
register number 1 of the sensor register table - which is usually the product
identifier - of the camera registered as "/dev/video0":
[root@localhost #] cd /sys/class/video4linux/video0
[root@localhost #] echo 1 > i2c_reg
[root@localhost #] cat i2c_val
Note that if the sensor registers can not be read, "cat" will fail.
To avoid race conditions, all the I/O accesses to the files are serialized.
9. Supported devices
====================
None of the names of the companies as well as their products will be mentioned
here. They have never collaborated with the author, so no advertising.
From the point of view of a driver, what unambiguously identify a device are
its vendor and product USB identifiers. Below is a list of known identifiers of
devices mounting the ET61X[12]51 PC camera controllers:

10. Notes for V4L2 application developers
========================================
This driver follows the V4L2 API specifications. In particular, it enforces two
rules:
- exactly one I/O method, either "mmap" or "read", is associated with each
file descriptor. Once it is selected, the application must close and reopen the
device to switch to the other I/O method;
- although it is not mandatory, previously mapped buffer memory should always
be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's.
The same number of buffers as before will be allocated again to match the size
of the new video frames, so you have to map the buffers again before any I/O
attempts on them.
Consistently with the hardware limits, this driver also supports image
downscaling with arbitrary scaling factors from 1 and 2 in both directions.
However, the V4L2 API specifications don't correctly define how the scaling
factor can be chosen arbitrarily by the "negotiation" of the "source" and
"target" rectangles. To work around this flaw, we have added the convention
that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the
scaling factor is restored to 1.
This driver supports two different video formats: the first one is the "8-bit
Sequential Bayer" format and can be used to obtain uncompressed video data
from the device through the current I/O method, while the second one provides
"raw" compressed video data (without frame headers not related to the
compressed data). The current compression quality may vary from 0 to 1 and can
be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP
V4L2 ioctl's.

The driver is divided into two modules: the basic one, "w9968cf", is needed for
the supported devices to work; the second one, "w9968cf-vpp", is an optional
module, which provides some useful video post-processing functions like video
decoding, up-scaling and colour conversions. Once the driver is installed,
every time an application tries to open a recognized device, "w9968cf" checks
the presence of the "w9968cf-vpp" module and loads it automatically by default.

Please keep in mind that official kernels do not include the second module for
performance purposes. However it is always recommended to download and install
the latest and complete release of the driver, replacing the existing one, if
present: it will be still even possible not to load the "w9968cf-vpp" module at
all, if you ever want to. Another important missing feature of the version in
the official Linux 2.4 kernels is the writeable /proc filesystem interface.
Note that the official kernels do neither include nor support the second

Page migration
--------------
Page migration allows the moving of the physical location of pages between
nodes in a numa system while the process is running. This means that the
virtual addresses that the process sees do not change. However, the
system rearranges the physical location of those pages.
The main intend of page migration is to reduce the latency of memory access
by moving pages near to the processor where the process accessing that memory
is running.
Page migration allows a process to manually relocate the node on which its
pages are located through the MF_MOVE and MF_MOVE_ALL options while setting
a new memory policy. The pages of process can also be relocated
from another process using the sys_migrate_pages() function call. The
migrate_pages function call takes two sets of nodes and moves pages of a
process that are located on the from nodes to the destination nodes.
Manual migration is very useful if for example the scheduler has relocated
a process to a processor on a distant node. A batch scheduler or an
administrator may detect the situation and move the pages of the process
nearer to the new processor. At some point in the future we may have
some mechanism in the scheduler that will automatically move the pages.
Larger installations usually partition the system using cpusets into
sections of nodes. Paul Jackson has equipped cpusets with the ability to
move pages when a task is moved to another cpuset. This allows automatic
control over locality of a process. If a task is moved to a new cpuset
then also all its pages are moved with it so that the performance of the
process does not sink dramatically (as is the case today).
Page migration allows the preservation of the relative location of pages
within a group of nodes for all migration techniques which will preserve a
particular memory allocation pattern generated even after migrating a
process. This is necessary in order to preserve the memory latencies.
Processes will run with similar performance after migration.
Page migration occurs in several steps. First a high level
description for those trying to use migrate_pages() and then
a low level description of how the low level details work.
A. Use of migrate_pages()
-------------------------
1. Remove pages from the LRU.
Lists of pages to be migrated are generated by scanning over
pages and moving them into lists. This is done by
calling isolate_lru_page() or __isolate_lru_page().
Calling isolate_lru_page increases the references to the page
so that it cannot vanish under us.
2. Generate a list of newly allocates page to move the contents
of the first list to.
3. The migrate_pages() function is called which attempts
to do the migration. It returns the moved pages in the
list specified as the third parameter and the failed
migrations in the fourth parameter. The first parameter
will contain the pages that could still be retried.
4. The leftover pages of various types are returned
to the LRU using putback_to_lru_pages() or otherwise
disposed of. The pages will still have the refcount as
increased by isolate_lru_pages()!
B. Operation of migrate_pages()
--------------------------------
migrate_pages does several passes over its list of pages. A page is moved
if all references to a page are removable at the time.
Steps:
1. Lock the page to be migrated
2. Insure that writeback is complete.
3. Make sure that the page has assigned swap cache entry if
it is an anonyous page. The swap cache reference is necessary
to preserve the information contain in the page table maps.
4. Prep the new page that we want to move to. It is locked
and set to not being uptodate so that all accesses to the new
page immediately lock while we are moving references.
5. All the page table references to the page are either dropped (file backed)
or converted to swap references (anonymous pages). This should decrease the
reference count.
6. The radix tree lock is taken
7. The refcount of the page is examined and we back out if references remain
otherwise we know that we are the only one referencing this page.
8. The radix tree is checked and if it does not contain the pointer to this
page then we back out.
9. The mapping is checked. If the mapping is gone then a truncate action may
be in progress and we back out.
10. The new page is prepped with some settings from the old page so that accesses
to the new page will be discovered to have the correct settings.
11. The radix tree is changed to point to the new page.
12. The reference count of the old page is dropped because the reference has now
been removed.
13. The radix tree lock is dropped.
14. The page contents are copied to the new page.
15. The remaining page flags are copied to the new page.
16. The old page flags are cleared to indicate that the page does
not use any information anymore.
17. Queued up writeback on the new page is triggered.
18. If swap pte's were generated for the page then remove them again.
19. The locks are dropped from the old and new page.
20. The new page is moved to the LRU.

Select the desired split between kernel and user memory.
If the address range available to the kernel is less than the
physical memory installed, the remaining memory will be available
as "high memory". Accessing high memory is a little more costly
than low memory, as it needs to be mapped into the kernel first.
Note that increasing the kernel address space limits the range
available to user programs, making the address space there
tighter. Selecting anything other than the default 3G/1G split
will also likely make your kernel incompatible with binary-only
kernel modules.
If you are not absolutely sure what you are doing, leave this
