The highlight of this release is gen4, from 965g to gm45. Quite an old
bug surfaced in the shader assembly, sparking a chance to review a few
design choices within that backend and experiment on fresh ways to
workaround the remaining issues.

 * Avoid using inplace XOR'ed uploads for very large buffers

 * Fix the gen4/5 opacity shader

 * Queue a pending vblank request after flip completion

 * Avoid migrating an uninitialised pixmap for use as a render source

 * Improve handing of texture fallbacks for 830/845.

Chris Wilson (45):
      sna: Compile against ancient libdrm
      sna/dri: Prevent scheduling a swap on stale buffers
      sna/dri: Apply the can_blit() check for CopyRegion

      sna/dri: Clear the last-used-cpu flag when performing CopyRegion
      Remove useless indirection of intel_chipsets
      sna/gen6+: Tweak prefer-blt to offset latency when in rc6
      sna/dri: Avoid setting off-delay after a failed flip (use-after-free)
      sna/dri: Add an assert that the cached DRI2 buffer is pinned for DRI
      sna/dri: Avoid a NULL dereference inside a DBG
      sna/dri: Queue a vblank-continuation after flip-completion

      sna: Remove the kgem_bo_is_mappable refcnt assertion from freed paths
      sna: Do not dispose of a shadow pixmap
      sna: Do not migrate uninitialised pixmaps
      sna: Add the missing assertion for !proxy
      sna: Skip uploading unintialiased pixmap data
      sna: Assert that we do not replace a GPU bo with a proxy
      sna/gen3+: Clear the render.vbo when replacing it for vertex upload
      Revert "uxa: Refactor early-exit paths of uxa_try_driver_composite()."
      sna/gen4: Use a dummy white mask to avoid the flush w/a when compositing
      sna/gen4: Backport the more efficient composite box emitters
      sna/gen4: Move the flush from inside the spans to emit_state()
      sna/gen4: Update render fill routines to use the dummy mask
      sna/gen4: Reduce the flush before performing the CA pass
      sna/gen4: Pass the mask channel explicitly rather than through a dummy mask
      sna/gen4: Set composite op before testing for a BLT compatible op
      sna/gen4: Force composite(WHITE, glyph) for building the glyphstring mask
      sna/gen4: Don't force a flush for the dirty target if the we do not read back
      sna/gen4: Revert changes to 965g[m]
      sna/g4x: Use the render pipeline more often for composite operations
      sna/g4x: Refine the w/a for the broken sf shader
      sna: Make GPU idle more consistent during wakeup
      sna: Transform a simple repeat pattern into range of the BLT
      sna: Exploit the alpha-fixup of the BLT for texture format conversions
      2.20.14 release

Eric Anholt (5):
      configure.ac: Fix bad syntax for test calls
      uxa/dri: Factor out the repeated swap fallback code.
      uxa: Add printf attribute to intel_debug_fallback().
      uxa: Work around uninitialized-value warning.
      uxa: Refactor early-exit paths of uxa_try_driver_composite().
