+			===========

+Introduction
+------------
+
+   The kernel provides an interface to manage DMA transfers
+   using the DMA channels in the cpu, so that the central
+   duty of managing channel mappings, and programming the
+   channel generators is in one place.
+
+
+DMA Channel Ordering
+--------------------
+
+   Many of the range do not have connections for the DMA
+   channels to all sources, which means that some devices
+   have a restricted number of channels that can be used.
+
+   To allow flexibilty for each cpu type and board, the
+   dma code can be given an dma ordering structure which
+   allows the order of channel search to be specified, as
+   well as allowing the prohibition of certain claims.
+
+   struct s3c24xx_dma_order has a list of channels, and
+   each channel within has a slot for a list of dma
+   channel numbers. The slots are searched in order, for
+   the presence of a dma channel number with DMA_CH_VALID
+   orred in.
+
+   If the order has the flag DMA_CH_NEVER set, then after
+   checking the channel list, the system will return no
+   found channel, thus denying the request.
+
+   A board support file can call s3c24xx_dma_order_set()
+   to register an complete ordering set. The routine will
+   copy the data, so the original can be discared with
+   __initdata.

+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.

 The fan speed control features are limited to manual PWM mode. Automatic
 "Smart Guardian" mode control handling is not implemented. However
 if you want to go for "manual mode" just write 1 to pwmN_enable.
+
+If you are only able to control the fan speed with very small PWM values,
+try lowering the PWM base frequency (pwm1_freq). Depending on the fan,
+it may give you a somewhat greater control range. The same frequency is
+used to drive all fan outputs, which is why pwm2_freq and pwm3_freq are
+read-only.

+Implementation Details
+----------------------
+
+Future driver development should bear in mind that the following registers have
+different functions on the 627EHF and the 627DHG. Some registers also have
+different power-on default values, but BIOS should already be loading
+appropriate defaults. Note that bank selection must be performed as is currently
+done in the driver for all register addresses.
+
+0x49:  only on DHG, selects temperature source for AUX fan, CPU fan0
+0x4a:  not completely documented for the EHF and the DHG documentation assigns
+       different behavior to bits 7 and 6, including extending the temperature
+       input selection to SmartFan I, not just SmartFan III. Testing on the EHF
+       will reveal whether they are compatible or not.
+
+0x58:  Chip ID: 0xa1=EHF 0xc1=DHG
+0x5e:  only on DHG, has bits to enable "current mode" temperature detection and
+       critical temperature protection
+0x45b: only on EHF, bit 3, vin4 alarm (EHF supports 10 inputs, only 9 on DHG)
+0x552: only on EHF, vin4
+0x558: only on EHF, vin4 high limit
+0x559: only on EHF, vin4 low limit
+0x6b:  only on DHG, SYS fan critical temperature
+0x6c:  only on DHG, CPU fan0 critical temperature
+0x6d:  only on DHG, AUX fan critical temperature
+0x6e:  only on DHG, CPU fan1 critical temperature
+
+0x50-0x55 and 0x650-0x657 are marked "Test Register" for the EHF, but "Reserved
+       Register" for the DHG
+
+The DHG also supports PECI, where the DHG queries Intel CPU temperatures, and
+the ICH8 southbridge gets that data via PECI from the DHG, so that the
+southbridge drives the fans. And the DHG supports SST, a one-wire serial bus.

+Sony Notebook Control Driver (SNC) Readme
+-----------------------------------------
+	Copyright (C) 2004- 2005 Stelian Pop <stelian@popies.net>
+	Copyright (C) 2007 Mattia Dongili <malattia@linux.it>
+
+This mini-driver drives the SNC device present in the ACPI BIOS of
+the Sony Vaio laptops.
+
+It gives access to some extra laptop functionalities. In its current
+form, this driver let the user set or query the screen brightness
+through the backlight subsystem and remove/apply power to some devices.
+
+Backlight control:
+------------------
+If your laptop model supports it, you will find sysfs files in the
+/sys/class/backlight/sony/
+directory. You will be able to query and set the current screen
+brightness:
+	brightness		get/set screen brightness (an iteger
+				between 0 and 7)
+	actual_brightness	reading from this file will query the HW
+				to get real brightness value
+	max_brightness		the maximum brightness value
+
+
+Platform specific:
+------------------
+Loading the sony-laptop module will create a
+/sys/devices/platform/sony-laptop/
+directory populated with some files.
+
+You then read/write integer values from/to those files by using
+standard UNIX tools.
+
+The files are:
+	brightness_default	screen brightness which will be set
+				when the laptop will be rebooted
+	cdpower			power on/off the internal CD drive
+	audiopower		power on/off the internal sound card
+	lanpower		power on/off the internal ethernet card
+				(only in debug mode)
+
+Note that some files may be missing if they are not supported
+by your particular laptop model.
+
+Example usage:
+	# echo "1" > /sys/devices/platform/sony-laptop/brightness_default
+sets the lowest screen brightness for the next and later reboots,
+	# echo "8" > /sys/devices/platform/sony-laptop/brightness_default
+sets the highest screen brightness for the next and later reboots,
+	# cat /sys/devices/platform/sony-laptop/brightness_default
+retrieves the value.
+
+	# echo "0" > /sys/devices/platform/sony-laptop/audiopower
+powers off the sound card,
+	# echo "1" > /sys/devices/platform/sony-laptop/audiopower
+powers on the sound card.
+
+Development:
+------------
+
+If you want to help with the development of this driver (and
+you are not afraid of any side effects doing strange things with
+your ACPI BIOS could have on your laptop), load the driver and
+pass the option 'debug=1'.
+
+REPEAT: DON'T DO THIS IF YOU DON'T LIKE RISKY BUSINESS.
+
+In your kernel logs you will find the list of all ACPI methods
+the SNC device has on your laptop. You can see the GCDP/GCDP methods
+used to pwer on/off the CD drive, but there are others.
+
+I HAVE NO IDEA WHAT THOSE METHODS DO.
+
+The sony-laptop driver creates, for some of those methods (the most
+current ones found on several Vaio models), an entry under
+/sys/devices/platform/sony-laptop, just like the 'cdpower' one.
+You can create other entries corresponding to your own laptop methods by
+further editing the source (see the 'sony_acpi_values' table, and add a new
+entry to this table with your get/set method names using the
+HANDLE_NAMES macro).
+
+Your mission, should you accept it, is to try finding out what
+those entries are for, by reading/writing random values from/to those
+files and find out what is the impact on your laptop.
+
+Should you find anything interesting, please report it back to me,
+I will not disavow all knowledge of your actions :)
+
+Bugs/Limitations:
+-----------------
+
+* This driver is not based on official documentation from Sony
+  (because there is none), so there is no guarantee this driver
+  will work at all, or do the right thing. Although this hasn't
+  happened to me, this driver could do very bad things to your
+  laptop, including permanent damage.
+
+* The sony-laptop and sonypi drivers do not interact at all. In the
+  future, sonypi could use sony-laptop to do (part of) its business.
+
+* spicctrl, which is the userspace tool used to communicate with the
+  sonypi driver (through /dev/sonypi) does not try to use the
+  sony-laptop driver. In the future, spicctrl could try sonypi first,
+  and if it isn't present, try sony-laptop instead.

+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.

+
+     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.

+	  0 = Normal (UV)
+	  1 = Swapped (VU)
+
+     In normal usage, the first plane is Y & the second plane is UV. Though the
+     order of the planes can be swapped, only the byte order of the second plane
+     can be swapped. This isn't much use for the Y plane, but can be useful for
+     the UV plane.

+
+     These three registers control the vertical aliasing filter for the Y plane.
+     Operation is similar to the horizontal Y filter (2804). The only real

+
+     NOTE: For both registers, the resulting image must be fully visible on

+     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.

+ *   - dst is writable
+ * memcpy uses the standard calling convention
+ *
+ * __copy_user copies up to len bytes from src to dst and sets a2 (len) to
+ * the number of uncopied bytes due to an exception caused by a read or write.
+ * __copy_user assumes that src and dst don't overlap, and that the call is

+ *   copy_to_user
+ *     - src is readable  (no exceptions when reading src)
+ *   copy_from_user
+ *     - dst is writable  (no exceptions when writing dst)
+ * __copy_user uses a non-standard calling convention; see

+/*
+ * Implementation

+ * The exception handler for loads requires that:

+ *  2- src_entry <= src < AT, and
+ *  3- (dst - src) == (dst_entry - src_entry),
+ * The _entry suffix denotes values when __copy_user was called.
+ *
+ * (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
+ * (2) is met by incrementing src by the number of bytes copied
+ * (3) is met by not doing loads between a pair of increments of dst and src
+ *
+ * The exception handlers for stores adjust len (if necessary) and return.
+ * These handlers do not need to overwrite any data.

+ * For __rmemcpy and memmove an exception is always a kernel bug, therefore

+   image sensors connected to the SN9C1XX bridges. The entire API is documented
    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
-      function to the two corresponding tables SENSOR_TABLE and ID_TABLE (see
-      below);
+      function to the two corresponding tables in sn9c102_devtable.h;
    3) implement the methods that you want/need (and fill the rest of the main
       structure accordingly).

+ * The actual system manager is implemented as an application running in the

+ * through port 2 of the vuart using a simple packet message protocol.
+ * Messages are comprised of a fixed field header followed by a message

+	  If you say yes here you get support for the Philips PCF8583
+	  RTC chip found on Acorn RiscPCs.  This driver supports the
+	  platform specific method of retrieving the current year from
+	  the RTC's SRAM.
 
 	  This driver can also be built as a module. If so, the module
 	  will be called rtc-pcf8583.

- *	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.
- *

- *	it under the terms of the GNU General Public License as published by
- *	the Free Software Foundation; either version 2 of the License, or
- *	(at your option) any later version.
- *
- *	This program is distributed in the hope that it will be useful,
- *	but WITHOUT ANY WARRANTY; without even the implied warranty of
- *	MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
- *	GNU General Public License for more details.
- *
- *	You should have received a copy of the GNU General Public License
- *	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

- *	linux/drivers/sbus/char/aurora.h -- Aurora multiport driver
- *
- *	Copyright (c) 1999 by Oliver Aldulea (oli@bv.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

- *	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.

-/*
- * Todo list:
- *
- * memcpy_to_flash() and memcpy_from_flash() functions.
- *
- * Implementation of hard links.
- *
- * Organize the source code in a better way. Against the VFS we could
- * have jffs_ext.c, and against the block device jffs_int.c.
- * A better file-internal organization too.
- *
- * A better checksum algorithm.
- *
- * Consider endianness stuff. ntohl() etc.
- *
- * Are we handling the atime, mtime, ctime members of the inode right?
- *
- * Remove some duplicated code. Take a look at jffs_write_node() and
- * jffs_rewrite_data() for instance.
- *
- * Implement more meaning of the nlink member in various data structures.
- * nlink could be used in conjunction with hard links for instance.
- *
- * Better memory management. Allocate data structures in larger chunks
- * if possible.
- *
- * If too much meta data is stored, a garbage collect should be issued.
- * We have experienced problems with too much meta data with for instance
- * log files.
- *
- * Improve the calls to jffs_ioctl(). We would like to retrieve more
- * information to be able to debug (or to supervise) JFFS during run-time.

 	  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

+	  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

+	  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 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).
