      drm/i915: fix i915_frequency_info on BDW · 9dd3c605
      Paulo Zanoni authored 
      The GEN6_PM* registers don't exist on BDW anymore, so when we read
this file we trigger unclaimed register errors. The equivalent BDW
register for PMs is GEN8_GT_I*R(2), so use it.

      drm/i915: Add 180 degree primary plane rotation support · 48404c1e
      Sonika Jindal authored 
      Primary planes support 180 degree rotation. Expose the feature
through rotation drm property.

v2: Calculating linear/tiled offsets based on pipe source width and
height. Added 180 degree rotation support in ironlake_update_plane.

v3: Checking if CRTC is active before issueing update_plane. Added
wait for vblank to make sure we dont overtake page flips. Disabling
FBC since it does not work with rotated planes.

v4: Updated rotation checks for pending flips, fbc disable. Creating
rotation property only for Gen4 onwards. Property resetting as part
of lastclose.

v5: Resetting property in i915_driver_lastclose properly for planes
and crtcs. Fixed linear offset calculation that was off by 1 w.r.t
width in i9xx_update_plane and ironlake_update_plane. Removed tab
based indentation and unnecessary braces in intel_crtc_set_property
and intel_update_fbc. FBC and flip related checks should be done only
for valid crtcs.

v6: Minor nits in FBC disable checks for comments in intel_crtc_set_property
and positioning the disable code in intel_update_fbc.

v7: In case rotation property on inactive crtc is updated, we return
successfully printing debug log as crtc is inactive and only property change
is preserved.

v8: update_plane is changed to update_primary_plane, crtc->fb is changed to
crtc->primary->fb  and return value of update_primary_plane is ignored.

v9: added rotation property to primary plane instead of crtc. Removing reset
of rotation property from lastclose. rotation_property is moved to
drm_mode_config, so drm layer will take care of resetting. Adding updation of
fbc when rotation is set to 0. Allowing rotation only if value is
different than old one.

v10: Calling intel_primary_plane_setplane instead of update_primary_plane in
set_property(Daniel).

v11: Using same set_property function for both primary and sprite, Adding
primary plane specific code in the same function (Matt).

v12: Removing disabling/ enabling of fbc from set_property because it is done
from intel_pipe_set_base. Other formatting

v13: we need to call disable_fbc before changing the rotation to 180,
disable_fbc from intel_pipe_set_base gets called very late, that will
be used to re-enable fbc if rotation is set to 0 (Ville).

hunk to disable fbc when rotated 180 degree. And make checkpatch
happier.]

      drm/i915: Updating plane parameters for primary plane in setplane · ce54d85a
      Sonika Jindal authored 
      This unifies how the primary plane functions work with how the sprite
functions works, which allows us to reuse them to update primary plane
properties.

v2: Moving setting of plane members in the end to take care of failure cases and
not-visible cases (Matt).

      drm/i915: Rework GPU reset sequence to match driver load & thaw · 6689c167
      McAulay, Alistair authored 
      This patch is to address Daniels concerns over different code during reset:

http://lists.freedesktop.org/archives/intel-gfx/2014-June/047758.html

"The reason for aiming as hard as possible to use the exact same code for
driver load, gpu reset and runtime pm/system resume is that we've simply
seen too many bugs due to slight variations and unintended omissions."

Tested using igt drv_hangman.

V2: Cleaner way of preventing check_wedge returning -EAGAIN
V3: Clean the last_context during reset, to ensure do_switch() does the MI_SET_CONTEXT. As per review.

      drm/qxl: enables gem prime helpers for qxl using dummy driver callbacks · 47c12968
      Andreas Pokorny authored 
      As there should not be any other virtual device that might share buffers,
the callbacks remain empty stubs. Still prime can be used to transfer buffers
between processes that use qxl.
