721ebe005c reverse CONFIG_ACPI_PROC_EVENT default
Sigh.  Again an ACPI assault on the Thinkpad's Fn+F4 to suspend to RAM.
The default and text for CONFIG_THINKPAD_ACPI_INPUT_ENABLED were fixed
in -rc3, but now commit 14e04fb34f ("ACPI:
Schedule /proc/acpi/event for removal") introduces the ACPI_PROC_EVENT
config entry, and defaults it to 'n' to disable it again.

Change default to y, and add comment to make it clearer that n is for
future distros.

14e04fb34f ACPI: Schedule /proc/acpi/event for removal
Schedule /proc/acpi/event for removal in 6 months.

Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event()
to make sure there is no confusion that it is for /proc/acpi/event only.

Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event.
There is no functional change if CONFIG_ACPI_PROC_EVENT=y

128a2bcf9d ACPI: delete CONFIG_ACPI_PROCFS_SLEEP (again)
CONFIG_ACPI_PROCFS_SLEEP is a NO-OP -- delete it (again).

Apparently 296699de6b creating CONFIG_SUSPEND
and CONFIG_PM_SLEEP was based on an out-dated version of drivers/acpi/Kconfig,
as it erroneously restored this recently deleted config option.

296699de6b Introduce CONFIG_SUSPEND for suspend-to-Ram and standby
Introduce CONFIG_SUSPEND representing the ability to enter system sleep
states, such as the ACPI S3 state, and allow the user to choose SUSPEND
and HIBERNATION independently of each other.

Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
been chosen and the kernel is intended for SMP systems.

Also, introduce CONFIG_PM_SLEEP which is automatically selected if
CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
code needed for both suspend and hibernation.

The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the
changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
the number of ifdefs).

There are many other files in which CONFIG_PM can be replaced with
CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
the future.

e8b2fd0122 ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from source
As it was a synonym for (CONFIG_ACPI && CONFIG_X86),

7c5aa6642f ACPI: Kconfig: always enable CONFIG_ACPI_SLEEP on X86
The SMP dependency on HOTPLUG_CPU and SUSPEND_SMP
caused more harm than good -- making ACPI sleep
support vanish for configs missing those options.
So simply select them on the (ACPI && SMP && X86) systems
that need them.

Also, remove the prompt for ACPI_SLEEP,
virtually nobody (intentionally) enables ACPI without it.

43532c8a46 ACPI: Kconfig: fold /proc/acpi/sleep under CONFIG_ACPI_PROCFS
/proc/acpi/sleep has had its own "default n" option,
ACPI_SLEEP_PROC_SLEEP, for many months.
Time to delete ACPI_SLEEP_PROC_SLEEP.

Users that still need /proc/acpi/sleep can still get it
along with the other deprecated /proc/acpi files
by enabling CONFIG_ACPI_PROCFS.

Also delete ACPI_SLEEP_PROC_FS, which was an umbrella
for /proc/acpi/sleep, wakeup, alarm, because it was
effectively just a synonym for ACPI_SLEEP.

798d910398 ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACE
Split ACPI_DEBUG into function trace enabled and not enabled.

Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.

Size of kernel image increased on test compile:
+ 48k  (Full ACPI_DEBUG)
+ 35k  (ACPI_DEBUG with function trace compiled out)

Performance without function trace is also much better.

Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.

23b0f015bf ACPI: video: output switch sysfs support
Requires CONFIG_VIDEO_OUTPUT_CONTROL and CONFIG_ACPI_VIDEO.

After loading output.ko and video.ko, you would have
/sys/class/video_output and several device acpi_videoNum there.

For example, I got acpi_video0, acpi_video1,acpi_video2,and acpi_video3
under /sys/class/video_output on my T40.
I can query the status of  output device0 by running " cat
/sys/class/video_output/acpi_video0
" The return value is defined in ACPI SPEC B.5.5 _DCS(Return the
Status of Output Device).  Also you can turn off video1 and turn on
video0  by " echo 0 > acpi_video1; echo 0x80000000 > acpi_video0".
Please reference ACPI SPEC  B.5.7 _DSS for the parameter definition.

Please note that it may or may NOT works purely depending on if
your vendor providing correct ACPI video extension support in bios.
the driver output.ko and video.ko just works like a interface to
invoke BIOS.
