      drm/i915: range-restricted bind_to_gtt · 920afa77
      Daniel Vetter authored
      Like before add a parameter mappable (also to gem_object_pin) and
      set it depending upon the context. Only bos that are brought into
      the gtt due to an execbuffer call can be put into the unmappable
      part of the gtt, everything else (especially pinned objects) need
      to be put into the mappable part of the gtt.

      drm/i915: range-restricted eviction support · a6e0aa42
      Daniel Vetter authored
      Add a mappable parameter to i915_gem_evict_something to distinguish
      the two cases (non-restricted vs. mappable gtt allocations). No
      functional changes because the mappable limit is set to the end of
      the gtt currently.

      drm/i915: Fix hangcheck to handle multiple rings · 893eead0
      Chris Wilson authored
      Currently, we believe the GPU is idle if just the RENDER ring is idle.
      This is obviously wrong if we only using either the BLT or the BSD
      rings and so masking genuine hangs.

      drm/i915: Move object to GPU domains after dispatching execbuffer · 7e318e18
      Chris Wilson authored
      In the event that we fail to dispatch the execbuffer, for example if
      there is insufficient space on the ring, we were leaving the objects in
      an inconsistent state. Notably they were marked as being in the GPU
      write domain, but were not added to the ring or any list. This would
      lead to inevitable oops:

      drm/i915: Propagate errors from writing to ringbuffer · e1f99ce6
      Chris Wilson authored
      Preparing the ringbuffer for adding new commands can fail (a timeout
      whilst waiting for the GPU to catch up and free some space). So check
      for any potential error before overwriting HEAD with new commands, and
      propagate that error back to the user where possible.

      Takashi Iwai authored
      Hi,
      
      while I looked through your changes in drm-intel git tree (as I've got
      a pressure for supporting DisplayPort audio), I stumbled on the
      possible bug in the commit a9756bb5
      
      	Author: Zhenyu Wang <zhenyuw@linux.intel.com>
      	Date:   Sun Sep 19 13:09:06 2010 +0800
      	drm/i915: Enable DisplayPort audio
      
      In this commit, you changed the return value of g4x_dp_detect()
      to "bit", but it should be "status", I suppose.
      
      [ickle: mea culpa.]
