Subject: [PATCH 0/2] Rework ACPI video driver
Date: Mon, 09 Sep 2013 16:37:23 +0800 [thread overview]
Message-ID: <522D88C3.7000808@intel.com> (raw)
The ACPI video module provides two functionalities: backlight control
and backlight hotkey event delivery. It is possible the backlight
control interface is broken while the system still needs its event
delivery, so it's worth to seperate the two interfaces clearly.
This patchset has two patches, the first is to sepeate the two
interfaces in the ACPI video module and the second one solves some
Win8 backlight control problems by removing ACPI video's backlight
interface while still keeping its event delivery functionality. Due
to some systems whose firmware claims win8 compatible have problems
with i915's backlight control interface, a module param is introduced
to give user a chance to select if they want to remove ACPI video's
backlight control interface. The param is set to false by default.
