+CPU load
+--------
+
+Linux exports various bits of information via `/proc/stat' and
+`/proc/uptime' that userland tools, such as top(1), use to calculate
+the average time system spent in a particular state, for example:
+
+ $ iostat
+ Linux 2.6.18.3-exp (linmac) 02/20/2007
+
+ avg-cpu: %user %nice %system %iowait %steal %idle
+ 10.01 0.00 2.92 5.44 0.00 81.63
+
+ ...
+
+Here the system thinks that over the default sampling period the
+system spent 10.01% of the time doing work in user space, 2.92% in the
+kernel, and was overall 81.63% of the time idle.
+
+In most cases the `/proc/stat' information reflects the reality quite
+closely, however due to the nature of how/when the kernel collects
+this data sometimes it can not be trusted at all.
+
+So how is this information collected? Whenever timer interrupt is
+signalled the kernel looks what kind of task was running at this
+moment and increments the counter that corresponds to this tasks
+kind/state. The problem with this is that the system could have
+switched between various states multiple times between two timer
+interrupts yet the counter is incremented only for the last state.
+
+
+Example
+-------
+
+If we imagine the system with one task that periodically burns cycles
+in the following manner:
+
+ time line between two timer interrupts
+|--------------------------------------|
+ ^ ^
+ |_ something begins working |
+ |_ something goes to sleep
+ (only to be awaken quite soon)
+
+In the above situation the system will be 0% loaded according to the
+`/proc/stat' (since the timer interrupt will always happen when the
+system is executing the idle handler), but in reality the load is
+closer to 99%.
+
+One can imagine many more situations where this behavior of the kernel
+will lead to quite erratic information inside `/proc/stat'.

+Description
+-----------
+
+rchar
+-----
+
+I/O counter: chars read
+The number of bytes which this task has caused to be read from storage. This
+is simply the sum of bytes which this process passed to read() and pread().
+It includes things like tty IO and it is unaffected by whether or not actual
+physical disk IO was required (the read might have been satisfied from
+pagecache)
+
+
+wchar
+-----
+
+I/O counter: chars written
+The number of bytes which this task has caused, or shall cause to be written
+to disk. Similar caveats apply here as with rchar.
+
+
+syscr
+-----
+
+I/O counter: read syscalls
+Attempt to count the number of read I/O operations, i.e. syscalls like read()
+and pread().
+
+
+syscw
+-----
+
+I/O counter: write syscalls
+Attempt to count the number of write I/O operations, i.e. syscalls like
+write() and pwrite().
+
+
+read_bytes
+----------
+
+I/O counter: bytes read
+Attempt to count the number of bytes which this process really did cause to
+be fetched from the storage layer. Done at the submit_bio() level, so it is
+accurate for block-backed filesystems. <please add status regarding NFS and
+CIFS at a later time>
+
+
+write_bytes
+-----------
+
+I/O counter: bytes written
+Attempt to count the number of bytes which this process caused to be sent to
+the storage layer. This is done at page-dirtying time.
+
+
+cancelled_write_bytes
+---------------------
+
+The big inaccuracy here is truncate. If a process writes 1MB to a file and
+then deletes the file, it will in fact perform no writeout. But it will have
+been accounted as having caused 1MB of write.
+In other words: The number of bytes which this process caused to not happen,
+by truncating pagecache. A task can cause "negative" IO too. If this task
+truncates some dirty pagecache, some IO which another task has been accounted
+for (in it's write_bytes) will not be happening. We _could_ just subtract that
+from the truncating task's write_bytes, but there is information loss in doing
+that.
+
+
+Note
+----
+
+At its current implementation state, this is a bit racy on 32-bit machines: if
+process A reads process B's /proc/pid/io while process B is updating one of
+those 64-bit counters, process A could see an intermediate result.
+
+
+More information about this can be found within the taskstats documentation in
+Documentation/accounting.

+PVR350 Video decoder registers 0x02002800 -> 0x02002B00
+=======================================================
+
+This list has been worked out through trial and error. There will be mistakes
+and omissions. Some registers have no obvious effect so it's hard to say what
+they do, while others interact with each other, or require a certain load
+sequence. Horizontal filter setup is one example, with six registers working
+in unison and requiring a certain load sequence to correctly configure. The
+indexed colour palette is much easier to set at just two registers, but again
+it requires a certain load sequence.
+
+Some registers are fussy about what they are set to. Load in a bad value & the
+decoder will fail. A firmware reload will often recover, but sometimes a reset
+is required. For registers containing size information, setting them to 0 is
+generally a bad idea. For other control registers i.e. 2878, you'll only find
+out what values are bad when it hangs.

+ (2818), as this register actually clocks the data through for the first
+ five.
+
+ To correctly program set the filter, this whole procedure must be done 16
+ times. The actual register contents are copied from a lookup-table in the
+ firmware which contains 4 different filter settings.

+ Most of these registers either control horizontal scaling, or appear linked

+ correctly set the divider in Reg 2874.
+
+ To enlarge:
+ Reg 2854 = (source_width * 0x00200000) / destination_width
+ Reg 2874 = No divide
+
+ To reduce from full size down to half size:
+ Reg 2854 = (source_width/2 * 0x00200000) / destination width
+ Reg 2874 = Divide by 2
+
+ To reduce from half size down to quarter size:
+ Reg 2854 = (source_width/4 * 0x00200000) / destination width
+ Reg 2874 = Divide by 4
+
+ The result is always rounded up.

+
+ When the bits-per-pixel is set to 8, the colour mode is ignored and
+ assumed to be 8 bit indexed. For 16 & 32 bits-per-pixel the colour depth
+ is honoured, and when using a colour depth that requires fewer bytes than
+ allocated the extra bytes are used as padding. So for a 32 bpp with 8 bit
+ index colour, there are 3 padding bytes per pixel. It's also possible to
+ select 16bpp with a 32 bit colour mode. This results in the pixel width
+ being doubled, but the color key will not work as expected in this mode.
+
+ Colour key is as it suggests. You designate a colour which will become
+ completely transparent. When using 565, 555 or 444 colour modes, the
+ colour key is always 16 bits wide. The colour to key on is set in Reg 2A18.
+
+ Local alpha is a per-pixel 256 step transparency, with 0 being transparent
+ and 255 being solid. This is only available in 32 bit & 8 bit indexed
+ colour modes.
+
+ Global alpha is a 256 step transparency that applies to the entire osd,
+ with 0 being transparent & 255 being solid.
+
+ It's possible to combine colour key, local alpha & global alpha.

+The compression is used to achieve high frame rates. With regard to the
+SN9C101, SN9C102 and SN9C103, the compression is based on the Huffman encoding
+algorithm described below, while the SN9C105 and SN9C120 the compression is

+The current video format may be selected or queried from the user application

+API specifications.
The name "Sequential Bayer" indicates the organization of the red, green and

Select this option, if you want to share the text segment of the
Linux kernel between different VM guests. This reduces memory
usage with lots of guests but greatly increases kernel size.
+ Also if a kernel was IPL'ed from a shared segment the kexec system

You should only select this option if you know what you are
doing and want to exploit this feature.

below. In the most general case, to support a sensor there are three steps
you have to follow:
1) define the main "sn9c102_sensor" structure by setting the basic fields;
2) write a probing function to be called by the core module when the USB
camera is recognized, then add both the USB ids and the name of that

- * linux/drivers/sbus/char/aurora.c -- Aurora multiport driver
- *
- * Copyright (c) 1999 by Oliver Aldulea (oli at bv dot ro)
- *
- * This code is based on the RISCom/8 multiport serial driver written
- * by Dmitry Gorodchanin (pgmdsg@ibi.com), based on the Linux serial
- * driver, written by Linus Torvalds, Theodore T'so and others.
- * The Aurora multiport programming info was obtained mainly from the
- * Cirrus Logic CD180 documentation (available on the web), and by
- * doing heavy tests on the board. Many thanks to Eddie C. Dost for the
- * help on the sbus interface.

- * along with this program; if not, write to the Free Software
- * Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
- *
- * Revision 1.0
- *
- * This is the first public release.
- *
- * Most of the information you need is in the aurora.h file. Please
- * read that file before reading this one.
- *
- * Several parts of the code do not have comments yet.
- *
- * n.b. The board can support 115.2 bit rates, but only on a few
- * ports. The total badwidth of one chip (ports 0-7 or 8-15) is equal
- * to OSC_FREQ div 16. In case of my board, each chip can take 6
- * channels of 115.2 kbaud. This information is not well-tested.
- *
- * Fixed to use tty_get_baud_rate().
- * Theodore Ts'o <tytso@mit.edu>, 2001-Oct-12

- * The Aurora multiport programming info was obtained mainly from the
- * Cirrus Logic CD180 documentation (available on the web), and by
- * doing heavy tests on the board. Many thanks to Eddie C. Dost for the
- * help on the sbus interface.

- *
- * Revision 1.0
- *
- * This is the first public release.
- *
- * This version needs a lot of feedback. This is the version that works
- * with _my_ board. My board is model 1600se, revision '@(#)1600se.fth
- * 1.2 3/28/95 1'. The driver might work with your board, but I do not
- * guarantee it. If you have _any_ type of board, I need to know if the
- * driver works or not, I need to know exactly your board parameters
- * (get them with 'cd /proc/openprom/iommu/sbus/sio16/; ls *; cat *')
- * Also, I need your board revision code, which is written on the board.
- * Send me the output of my driver too (it outputs through klogd).
- *
- * If the driver does not work, you can try enabling the debug options
- * to see what's wrong or what should be done.
- *
- * I'm sorry about the alignment of the code. It was written in a
- * 128x48 environment.
- *
- * I must say that I do not like Aurora Technologies' policy. I asked
- * them to help me do this driver faster, but they ended by something
- * like "don't call us, we'll call you", and I never heard anything
- * from them. They told me "knowing the way the board works, I don't
- * doubt you and others on the net will make the driver."
- * The truth about this board is that it has nothing intelligent on it.
- * If you want to say to somebody what kind of board you have, say that
- * it uses Cirrus Logic processors (CD180). The power of the board is
- * in those two chips. The rest of the board is the interface to the
- * sbus and to the peripherals. Still, they did something smart: they
- * reversed DTR and RTS to make on-board automatic hardware flow
- * control usable.
- * Thanks to Aurora Technologies for wasting my time, nerves and money.

+Verison 1.48
+------------
+Fix mtime bouncing around from local idea of last write times to remote time.
+Fix hang (in i_size_read) when simultaneous size update of same remote file
+on smp system corrupts sequence number. Do not reread unnecessarily partial page
+(which we are about to overwrite anyway) when writing out file opened rw.
+
Version 1.47

Fix oops in list_del during mount caused by unaligned string.

---help---
- Enable the possibility of suspending the machine.
- It doesn't need ACPI or APM.
- You may suspend your machine by 'swsusp' or 'shutdown -z <time>'
- (patch for sysvinit needed).
+ Enable the suspend to disk (STD) functionality.
- It creates an image which is saved in your active swap. Upon next
+ You can suspend your machine with 'echo disk > /sys/power/state'.
+ Alternatively, you can use the additional userland tools available
+ from <http://suspend.sf.net>.
+
+ In principle it does not require ACPI or APM, although for example
+ ACPI will be used if available.
+
+ It creates an image which is saved in your active swap. Upon the next
boot, pass the 'resume=/dev/swappartition' argument to the kernel to
have it detect the saved image, restore memory state from it, and
continue to run as before. If you do not want the previous state to
- be reloaded, then use the 'noresume' kernel argument. However, note
- that your partitions will be fsck'd and you must re-mkswap your swap
- partitions. It does not work with swap files.
+ be reloaded, then use the 'noresume' kernel command line argument.
+ Note, however, that fsck will be run on your filesystems and you will
+ need to run mkswap against the swap partition used for the suspend.
- Right now you may boot without resuming and then later resume but
- in meantime you cannot use those swap partitions/files which were
- involved in suspending. Also in this case there is a risk that buffers
- on disk won't match with saved ones.
+ It also works with swap files to a limited extent (for details see
+ <file:Documentation/power/swsusp-and-swap-files.txt>).
+
+ Right now you may boot without resuming and resume later but in the
+ meantime you cannot use the swap partition(s)/file(s) involved in
+ suspending. Also in this case you must not use the filesystems
+ that were mounted before the suspend. In particular, you MUST NOT
+ MOUNT any journaled filesystems mounted before the suspend or they
+ will get corrupted in a nasty way.
For more information take a look at <file:Documentation/power/swsusp.txt>.
- (For now, swsusp is incompatible with PAE aka HIGHMEM_64G on i386.
- we need identity mapping for resume to work, and that is trivial
- to get with 4MB pages, but less than trivial on PAE).
