What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY)
When: 2.6.21
Why: hotkey.c was an attempt to consolidate multiple drivers that use
the BIOS can be extracted and disassembled with acpidump
and iasl as documented in the pmtools package here:
http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils
-
Who: Len Brown <len.brown@intel.com>
---------------------------
+What: ACPI procfs interface
+When: July 2007
+Why: After ACPI sysfs conversion, ACPI attributes will be duplicated
+ in sysfs and the ACPI procfs interface should be removed.
+Who: Zhang Rui <rui.zhang@intel.com>
+
+---------------------------
+
What: /proc/acpi/button
When: August 2007
Why: /proc/acpi/button has been replaced by events to the input layer
Who: Jeff Garzik <jeff@garzik.org>
---------------------------
+
+What: sk98lin network driver
+When: July 2007
+Why: In kernel tree version of driver is unmaintained. Sk98lin driver
+ replaced by the skge driver.

+ Video Output Switcher Control
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ 2006 luming.yu@intel.com
+
+The output sysfs class driver provides an abstract video output layer that
+can be used to hook platform specific methods to enable/disable video output
+device through common sysfs interface. For example, on my IBM ThinkPad T42
+laptop, The ACPI video driver registered its output devices and read/write
+method for 'state' with output sysfs class. The user interface under sysfs is:
+
+linux:/sys/class/video_output # tree .

- * DESCRIPTION: This function is called to get an ACPI table header. The caller
- * supplies an pointer to a data area sufficient to contain an ACPI
- * struct acpi_table_header structure.
+ * RETURN: Status and pointer to the table
*
- * The header contains a length field that can be used to determine
- * the size of the buffer needed to contain the entire table. This
- * function is not valid for the RSD PTR table since it does not
- * have a standard header and is fixed length.
+ * DESCRIPTION: Obtain a table by an index into the global table list.

+ ---help---
+ This is the new Linux driver for Asus laptops. It may also support some
+ MEDION, JVC or VICTOR laptops. It makes all the extra buttons generate
+ standard ACPI events that go through /proc/acpi/events. It also adds
+ support for video output switching, LCD backlight control, Bluetooth and
+ Wlan control, and most importantly, allows you to blink those fancy LEDs.
+
+ For more information and a userspace daemon for handling the extra

-
- A big thank you to the S&K support for providing me so quickly with
- documentation!
-
- Also see http://www.syskonnect.com/
-
- Missing things:
-
- -> set debug level via ioctl instead of compile-time switches
- -> I didn't follow the development of the 2.1.x kernels, so my
- assumptions about which things changed with which kernel version
- are probably nonsense
-
-History:
- May 16th, 1999
- startup
- May 22st, 1999
- added private structure, methods
- begun building data structures in RAM
- May 23nd, 1999
- can receive frames, send frames
- May 24th, 1999
- modularized initialization of LANCE
- loadable as module
- still Tx problem :-(
- May 26th, 1999
- MC2 works
- support for multiple devices
- display media type for MC2+
- May 28th, 1999
- fixed problem in GetLANCE leaving interrupts turned off
- increase TX queue to 4 packets to improve send performance
- May 29th, 1999
- a few corrections in statistics, caught rcvr overruns
- reinitialization of LANCE/board in critical situations
- MCA info implemented
- implemented LANCE multicast filter
- Jun 6th, 1999
- additions for Linux 2.2
- Dec 25th, 1999
- unfortunately there seem to be newer MC2+ boards that react
- on IRQ 3/5/9/10 instead of 3/5/10/11, so we have to autoprobe
- in questionable cases...
- Dec 28th, 1999
- integrated patches from David Weinehall & Bill Wendling for 2.3
- kernels (isa_...functions). Things are defined in a way that
- it still works with 2.0.x 8-)
- Dec 30th, 1999
- added handling of the remaining interrupt conditions. That
- should cure the spurious hangs.
- Jan 30th, 2000
- newer kernels automatically probe more than one board, so the
- 'startslot' as a variable is also needed here
- June 1st, 2000
- added changes for recent 2.3 kernels
