drm/radeon: fix load detect on rn50 with hardcoded EDIDs.

2012-04-22T23:21:45+00:00

commit a09d431f344d854e4fe9cfac44f78cb8202f3eb7 upstream.

When the force changes went in back in 3.3.0, we ended up returning
disconnected in the !force case, and the connected in when forced,
as it hit the hardcoded check.

Fix it so all exits go via the hardcoded check and stop spurious
modesets on platforms with hardcoded EDIDs.

drm/radeon: disable MSI on RV515

2012-04-22T23:21:45+00:00

commit 16a5e32b83fd946312b9b13590c75d20c95c5202 upstream.

My rv515 card is very flaky with msi enabled. Every so often it loses a rearm
and never comes back, manually banging the rearm brings it back.

drm/radeon/kms: fix the regression of DVI connector check

2012-04-22T23:21:45+00:00

commit e36325071832f1ba96ac54fb8ba1459f08b05dd8 upstream.

The check of the encoder type in the commit [e00e8b5e: drm/radeon/kms:
fix analog load detection on DVI-I connectors] is obviously wrong, and
it's the culprit of the regression on my workstation with DVI-analog
connection resulting in the blank output.

Fixed the typo now.

drm/radeon: only add the mm i2c bus if the hw_i2c module param is set

2012-04-22T23:21:22+00:00

commit 46783150a6552f9513f08e62cfcc07125d6e502b upstream.

It seems it can corrupt the monitor EDID in certain cases on certain
boards when running sensors detect.  It's rarely used anyway outside
of AIW boards.

drm/i915/ringbuffer: Exclude last 2 cachlines of ring on 845g

2012-04-22T23:21:22+00:00

commit 27c1cbd06a7620b354cbb363834f3bb8df4f410d upstream.

The 845g shares the errata with i830 whereby executing a command
within 2 cachelines of the end of the ringbuffer may cause a GPU hang.

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.
