drm/i915: quirk away broken OpRegion VBT

2012-04-13T15:14:07+00:00

commit 25e341cfc33d94435472983825163e97fe370a6c upstream. Somehow the BIOS manages to screw things up when copying the VBT around, because the one we scrap from the VBIOS rom actually works.

drm/i915: Add lock on drm_helper_resume_force_mode

2012-04-13T15:14:06+00:00

commit 927a2f119e8235238a2fc64871051b16c9bdae75 upstream. i915_drm_thaw was not locking the mode_config lock when calling drm_helper_resume_force_mode. When there were multiple wake sources, this caused FDI training failure on SNB which in turn corrupted the display.

drm/i915: Sanitize BIOS debugging bits from PIPECONF

2012-04-13T15:14:06+00:00

commit f47166d2b0001fcb752b40c5a2d4db986dfbea68 upstream. Quoting the BSpec from time immemorial: PIPEACONF, bits 28:27: Frame Start Delay (Debug) Used to delay the frame start signal that is sent to the display planes. Care must be taken to insure that there are enough lines during VBLANK to support this setting. An instance of the BIOS leaving these bits set was found in the wild, where it caused our modesetting to go all squiffy and skewiff.

drm: Validate requested virtual size against allocated fb size

2012-04-13T15:14:06+00:00

commit 62fb376e214d3c1bfdf6fbb77dac162f6da04d7e upstream. mplayer -vo fbdev tries to create a screen that is twice as tall as the allocated framebuffer for "doublebuffering". By default, and all in-tree users, only sufficient memory is allocated and mapped to satisfy the smallest framebuffer and the virtual size is no larger than the actual. For these users, we should therefore reject any userspace request to create a screen that requires a buffer larger than the framebuffer originally allocated.

drm/i915: suspend fbdev device around suspend/hibernate

2012-04-02T16:27:20+00:00

commit 3fa016a0b5c5237e9c387fc3249592b2cb5391c6 upstream. Looking at hibernate overwriting I though it looked like a cursor, so I tracked down this missing piece to stop the cursor blink timer. I've no idea if this is sufficient to fix the hibernate problems people are seeing, but please test it. Both radeon and nouveau have done this for a long time. I've run this personally all night hib/resume cycles with no fails.

drm/radeon: Restrict offset for legacy hardware cursor.

2012-04-02T16:27:12+00:00

commit c4353016dac10133fa5d8535af83f0c4845a2915 upstream. The hardware only takes 27 bits for the offset, so larger offsets are truncated, and the hardware cursor shows random bits other than the intended ones.
