radeon: add AGPMode 1 quirk for RV250

2012-12-06T11:20:30Z

commit 45171002b01b2e2ec4f991eca81ffd8430fd0aec upstream. The Intel 82855PM host bridge / Mobility FireGL 9000 RV250 combination in an (outdated) ThinkPad T41 needs AGPMode 1 for suspend/resume (under KMS, that is). So add a quirk for it. (Change R250 to RV250 in comment for preceding quirk too.) Signed-off-by: Paul Bolle Signed-off-by: Alex Deucher Signed-off-by: Ben Hutchings

drm/radeon: properly track the crtc not_enabled case evergreen_mc_stop()

2012-12-06T11:20:29Z

commit 804cc4a0ad3a896ca295f771a28c6eb36ced7903 upstream. The save struct is not initialized previously so explicitly mark the crtcs as not used when they are not in use. Signed-off-by: Alex Deucher Signed-off-by: Ben Hutchings

drm/i915: Check VBIOS value for determining LVDS dual channel mode, too

2012-12-06T11:20:15Z

commit b03543857fd75876b96e10d4320b775e95041bb7 upstream. Currently i915 driver checks [PCH_]LVDS register bits to decide whether to set up the dual-link or the single-link mode. This relies implicitly on that BIOS initializes the register properly at boot. However, BIOS doesn't initialize it always. When the machine is booted with the closed lid, BIOS skips the LVDS reg initialization. This ends up in blank output on a machine with a dual-link LVDS when you open the lid after the boot. This patch adds a workaround for that problem by checking the initial LVDS register value in VBT.

ttm: Clear the ttm page allocated from high memory zone correctly

2012-12-06T11:20:07Z

commit ac207ed2471150e06af0afc76e4becc701fa2733 upstream. The TTM page can be allocated from high memory. In such case it is wrong to use the page_address(page) as the virtual address for the high memory page. bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=50241 Signed-off-by: Zhao Yakui Reviewed-by: Thomas Hellstrom Signed-off-by: Dave Airlie [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings

drm/i915/sdvo: clean up connectors on intel_sdvo_init() failures

2012-12-06T11:20:05Z

commit d0ddfbd3d1346c1f481ec2289eef350cdba64b42 upstream. Any failures in intel_sdvo_init() after the intel_sdvo_setup_output() call left behind ghost connectors, attached (with a dangling pointer) to the sdvo that has been cleaned up and freed. Properly destroy any connectors attached to the encoder.
