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.

Hot keys that have a valid keycode mapping are reported through the input layer if the input device is open. Otherwise, they will be reported as ACPI events, as they were before. Scan codes are reported (using EV_MSC MSC_SCAN events) along with EV_KEY KEY_UNKNOWN events. For backwards compatibility purposes, hot keys that used to be reported through ACPI events are not mapped to anything meaningful by default. Userspace is supposed to remap them if it wants to use the input device for hot key reporting. This patch is based on a patch by Richard Hughes <hughsient@xxxxxxxxx>.

This is the current behavior, and I set this to be the default. if immediate_undock == 0, then when the user presses the undock button, the laptop will send an event to userspace and do nothing. User space can query the "flags" sysfs entry to determine if an undock request has been made by the user (if bit 1 is set). User space will then need to write the undock sysfs entry to complete the undocking process.

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.

Sometimes user-space reads this file frequently, and on some systems _BST takes a long time to evaluate due to a slow EC. Further, when we move to sysfs, the values returned from _BST will be in multiple files, and evaluating _BST for each file read would make matters worse. Here code is added to support caching the results of _BST. A new module parameter "update_time" tells how many seconds the cached _BST should be used before it is re-evaluated. Currently, update_time defaults to 0, and so the existing behaviour of re-evaluating on each read retained.
