[Mesa-dev] [PATCH 0/9 v2] Add YUYV format support of dri image

[Zhao Halley]

Intel SNB/IVB platform supports rendering YUYV buffer to overlay plane, however YUYV is missing support from mesa/dri-image yet.
so I go ahead to add it; basing on it, libva can send YUYV buffer directly to wayland/weston, then weston output it to overlay plane.

I notice that there are some patches from Gwenole for YUV planar texture support. these patches have little to do with that. because:
    YUYV is packed format, it doesn't require additional attribute like 
       buffer layout (introduced by Gwenole)
    YUYV is introduced for overlay support, no shaders for texture is required.

update:
    - set internal_format to GL_YCBCR_MESA
    - improve gbm/intel-driver to support YUYV bo generation, 
      add handle2 (intel buffer name) in gbm
      buffer data update (intel_image_write with tiling support)
    - update test case to depend on gbm instead of intel driver directly

Zhao Halley (9):
  GL: add YUYV to dri image format
  mesa intel driver:
  egl wayland: add YUYV support
  gallium egl wayland: add YUYV support
  gbm dri backend: add YUYV support
  wayland-drm: add YUYV support
  gbm: add handle2(buffer region name)
  intel driver: add tiling support for intel_image_write()             
         all drm image are supported for write
  test: test case for wayland-drm in tests/wayland-drm
