2007-08-27reverse CONFIG_ACPI_PROC_EVENT defaultHugh Dickins
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 14e04fb34ffa82ee61ae69f98d8fca12d2e8e31c ("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.

2007-08-23ACPI: Schedule /proc/acpi/event for removalLen Brown
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 Signed-off-by: Len Brown <len.brown@intel.com>
2007-07-31ACPI: delete CONFIG_ACPI_PROCFS_SLEEP (again)Len Brown
CONFIG_ACPI_PROCFS_SLEEP is a NO-OP -- delete it (again). Apparently 296699de6bdc717189a331ab6bbe90e05c94db06 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.

2007-07-29Introduce CONFIG_SUSPEND for suspend-to-Ram and standbyRafael J. Wysocki
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. Signed-off-by: Rafael J.

2007-07-26Don't force-enable suspend/hibernate support just for ACPILinus Torvalds

2007-07-25ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from sourceLen Brown
As it was a synonym for (CONFIG_ACPI && CONFIG_X86), the ifdefs for it were more clutter than they were worth. For ia64, just add a few stubs in anticipation of future S3 or S4 support. Signed-off-by: Len Brown <len.brown@intel.com>
2007-07-24ACPI: Kconfig: always enable CONFIG_ACPI_SLEEP on X86Len Brown
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.

2007-07-24ACPI: Kconfig: fold /proc/acpi/sleep under CONFIG_ACPI_PROCFSLen Brown
/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. Signed-off-by: Len Brown <len.brown@intel.com>
2007-07-24ACPI: Kconfig: CONFIG_ACPI_PROCFS now defaults to NLen Brown

2007-07-22ACPI: create CONFIG_ACPI_DEBUG_FUNC_TRACEThomas Renninger
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.

2007-05-09ACPI: video: output switch sysfs supportLuming Yu
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.

Add ACPI debug attributes in sysfs. /proc/acpi/debug_layer && debug_level are deprecated by /sys/module/acpi/parameters/debug_layer && debug_level. NOTE: The operations to them are quite the same. E.g. if you want to enable ACPI_DB_INFO, ACPI_DB_WARN, ACPI_DB_ERROR and disable the others, #echo 0x13 >/sys/module/acpi/parameters/debug_level is OK, and a boot option "acpi.debug_level = 0x13" also works.

This reverts commit 2df910b4c3edcce9a0c12394db6f5f4a6e69c712. ACPI_BAY has not been merged into mainline yet, so the changes to ibm-acpi related Kconfig entries that depend on ACPI_BAY were permanently disabling ibm-acpi bay support.

2006-11-09ACPI: button: register with input layerDmitry Torokhov
In addition to signalling button/lid events through /proc/acpi/event, create separate input devices and report KEY_POWER, KEY_SLEEP and SW_LID through input layer. Also remove unnecessary casts and variable initializations, clean up formatting. Sleep button may autorepeat but userspace will have to filter duplicate sleep requests anyway (and discard unprocessed events right after wakeup). Unlike /proc/acpi/event interface input device corresponding to LID switch reports true lid state instead of just a counter. SW_LID is active when lid is closed.
