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

2012-04-22T22:31:16+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

2012-04-22T22:31:15+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

2012-04-22T22:31:15+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/i915: make rc6 module parameter read-only

People have been getting confused and thinking this is a runtime control.

drm/i915: properly compute dp dithering for user-created modes

2012-04-22T22:30:57+00:00

commit c4867936474183332db4c19791a65fdad6474fd5 upstream.

We've only computed whether we need to fall back to 6bpc due to dp
link bandwidth constrains in mode_valid, but not mode_fixup. Under
various circumstances X likes to create new modes which then lack
proper 6bpc flags (if required), resulting in mode_fixup failures and
ultimately black screens.

Chris Wilson pointed out that we still get things wrong for bpp > 24,
but that should be fixed in another patch (and it'll be easier because
this patch consolidates the logic).

The likely culprit for this regression is

    drm/i915: Force explicit bpp selection for intel_dp_link_required

v2: Fix indentation and tune down the too bold claim that this should
fix the world. Both noticed by Chris Wilson.

v3: Try to really git add things.

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

2012-04-22T22:30:57+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

2012-04-22T22:30:57+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.

commit afceb9319f21b18ee3bc15ee9a5f92e18ef8a8c9 upstream.

Some r4xx chips have the wrong frev in the
DVOEncoderControl table.  It should always be 1
on r4xx.  Fixes modesetting on DVO on r4xx chips
with the bad frev.

drm/i915: mask transcoder select bits before setting them on LVDS

commit 7885d2052bd94395e337709cfba093a41f273ff1 upstream.

The transcoder port may changed from mode set to mode set, so make sure
to mask out the selection bits before setting the right ones or we'll
get black screens when going from transcoder B to A.

drm/i915: quirk away broken OpRegion VBT

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.
