[RFCv3 00/14] Unified plane support

[Matt Roper <matthew.d.roper@intel.com>]

Previous revision and explanation of series:
   http://lists.freedesktop.org/archives/dri-devel/2014-March/055222.html

Main changes since last pass:
 * Added cursor plane support on i915.  Unfortunately it isn't possible to
   create nice generic helper functions that make use of the legacy API's for
   cursor planes as was done for primary planes; the legacy cursor ioctl's take
   a driver handle directly (e.g., from GEM) rather than a DRM framebuffer.
   With the unified plane support, we receive a DRM framebuffer via the SetPlane
   API, but have no way of turning that into a driver handle that can be passed
   to the legacy interfaces.
 * Updated msm and omapdrm to use their existing "private" planes as primary
   rather than using the primary helper functions.  (thanks Rob Clark!)
 * Fixed several s/crtc->fb/crtc->primary->fb/ conversions that were missed
   on the first pass (or new instances that popped up due to rebasing to
   the latest code).

I believe some of the next steps are:
 * Create some new read-only plane properties that describe in more detail the
   capabilities & limitations of various planes (max/min size, scaling
   capabilities, tiling restrictions, etc.) so that generic userspace
   compositors can make intelligent decisions about how best to use the various
   planes on the plane list.  If anyone has strong feelings on what these
   properties should look like, this would be a good time to start the
   discussion.
 * Update cursor support for the rest of the non-i915 drivers.  I believe the
   list of drivers that currently support cursors are: armada, ast, gma500,
   mgag200, msm, nouveau, radeon, vmwgfx, and qxl.
 * Update imx-drm's CRTC creation to use its existing private primary plane
   rather than using the primary helper function to create one.  
 * Provide patches for weston & xf86-video-modesetting that make use of the
   unified plane interface to make real-world testing of this patchset a
   bit easier.

Note that the first patch here is simply a build fix for current breakage of
the drm-intel-nightly branch of the drm-intel repo.


Matt Roper (14):
  SQUASH! drm/i915: Do not dereference pointers from ring buffer in
    evict event
  drm: Add support for multiple plane types
  drm: Add primary plane helpers

  drm: Add plane type property
  drm: Specify primary plane at CRTC initialization (v2)
  drm: Replace crtc fb with primary plane fb (v2)
  drm: Allow userspace to ask for full plane list (universal planes)
  drm/i915: Rename similar plane functions to avoid confusion
  drm/i915: Intel-specific primary plane handling
  drm: Specify cursor plane at CRTC initialization
