The ACPI video driver defers registration to the i915 driver if the system supports opregion-mediated backlight control. This registration was only being performed in the KMS case. Ensure it's done even if we don't have modesetting enabled. http://bugzilla.kernel.org/show_bug.cgi?id=13048Signed-off-by: NMatthew Garrett <mjg@redhat.com> Signed-off-by: NLen Brown <len.brown@intel.com>

The changes to opregion initialisation order meant that the ASLE setup code might not be run at the correct time. Ensure that the interrupts are set up. Signed-off-by: NMatthew Garrett <mjg@redhat.com> Signed-off-by: NEric Anholt <eric@anholt.net>

The i915 DRM triggers registration of the ACPI video driver on load. It should unregister it at unload in order to avoid generating backtraces on being reloaded. Signed-off-by: NMatthew Garrett <mjg@redhat.com> Signed-off-by: NEric Anholt <eric@anholt.net>

Intel graphics hardware that implements the ACPI IGD OpRegion spec requires that the list of display devices be populated before any ACPI video methods are called. Detect when this is the case and defer registration until the opregion code calls it. Fixes crashes on HP laptops. http://bugzilla.kernel.org/show_bug.cgi?id=11259Signed-off-by: NMatthew Garrett <mjg@redhat.com> Acked-by: NEric Anholt <eric@anholt.net> Signed-off-by: NLen Brown <len.brown@intel.com>

The pipestat fields affect reporting of all vblank-related interrupts, so we have to reset them during the irq_handler, and while enabling vblank interrupts. Otherwise, if a pipe status field had been set to non-zero before enabling reporting, we would never see an interrupt again. This patch adds i915_enable_pipestat and i915_disable_pipestat to abstract out the steps needed to change the reported interrupts.

This adds the support necessary for allowing ACPI backlight control to work on some newer Intel-based graphics systems. Tested on Thinkpad T61 and HP 2510p hardware. Signed-off-by: NMatthew Garrett <mjg@redhat.com> Signed-off-by: NDave Airlie <airlied@linux.ie>
