drm/i915: Check overlay stride errata for i830 and i845

2010-08-10T18:09:22+00:00

commit a1efd14a99483a4fb9308902397ed86b69454c99 upstream.

Apparently i830 and i845 cannot handle any stride that is not a multiple
of 256, unlike their brethren which do support 64 byte aligned strides.

drm/i915: Unset cursor if out-of-bounds upon mode change (v4)

2010-08-10T18:09:22+00:00

commit cda4b7d3a5b1dcbc0d8e7bad52134347798e9047 upstream.

The docs warn that to position the cursor such that no part of it is
visible on the pipe is an undefined operation. Avoid such circumstances
upon changing the mode, or at any other time, by unsetting the cursor if
it moves out of bounds.

"For normal high resolution display modes, the cursor must have at least a
single pixel positioned over the active screen.” (p143, p148 of the hardware
registers docs).

Fixes:

  Bug 24748 - [965G] Graphics crashes when resolution is changed with KMS
              enabled
  https://bugs.freedesktop.org/show_bug.cgi?id=24748

v2: Only update the cursor registers if they change.
v3: Fix the unsigned comparision of x,y against width,height.
v4: Always set CUR.BASE or else the cursor may become corrupt.

drm/radeon/kms: handle the case of no active displays properly in the bandwidth code

2010-08-10T18:09:22+00:00

commit e06b14ee91a2ddefc9a67443a6cd8ee0fa800115 upstream.

Logic was:
if (mode0 && mode1)
else if (mode0)
else

Should be:
if (mode0 && mode1)
else if (mode0)
else if (mode1)

Otherwise we may end up calculating the priority regs with
unitialized values.

drm/radeon/kms/r7xx: add workaround for hw issue with HDP flush

2010-08-10T18:09:22+00:00

commit 812d046915f48236657f02c06d7dc47140e9ceda upstream.

Use of HDP_*_COHERENCY_FLUSH_CNTL can cause a hang in certain
situations.  Add workaround.

drm/radeon: fall back to GTT if bo creation/validation in VRAM fails.

2010-08-10T18:09:22+00:00

commit e376573f7267390f4e1bdc552564b6fb913bce76 upstream.

This fixes a problem where on low VRAM cards we'd run out of space for validation.

drm/edid: Fix the HDTV hack sync adjustment

2010-07-29T06:14:43+00:00

We're adjusting horizontal timings only here, moving vsync was just a
slavish translation of a typo in the X server.

drm/i915: make sure we shut off the panel in eDP configs

2010-07-26T22:34:16+00:00

Fix error from the last pull request.  Making sure we shut the panel off
is more correct and saves power.
