@ -273,3 +273,48 @@ Why: Speedstep-centrino driver with ACPI hooks and acpi-cpufreq driver are
Who: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com>
---------------------------
What: ACPI hotkey driver (CONFIG_ACPI_HOTKEY)
When: 2.6.21
Why: hotkey.c was an attempt to consolidate multiple drivers that use
ACPI to implement hotkeys. However, hotkeys are not documented
in the ACPI specification, so the drivers used undocumented
vendor-specific hooks and turned out to be more different than
the same.
Further, the keys and the features supplied by each platform
are different, so there will always be a need for
platform-specific drivers.
So the new plan is to delete hotkey.c and instead, work on the
platform specific drivers to try to make them look the same
to the user when they supply the same features.
hotkey.c has always depended on CONFIG_EXPERIMENTAL
Who: Len Brown <len.brown@intel.com>
---------------------------
What: /sys/firmware/acpi/namespace
When: 2.6.21
Why: The ACPI namespace is effectively the symbol list for
the BIOS. The device names are completely arbitrary
and have no place being exposed to user-space.
For those interested in the BIOS ACPI namespace,
the BIOS can be extracted and disassembled with acpidump
and iasl as documented in the pmtools package here:

Who: Len Brown <len.brown@intel.com>
---------------------------
What: /proc/acpi/button
When: August 2007
Why: /proc/acpi/button has been replaced by events to the input layer
since 2.6.20.
