[Mesa-dev] [PATCH 0/5] add wayland-drm test with gbm/intel-driver update

[Kristensen, Kristian H]

Hi Halley,

I don't think we need to create YUYV buffers in GBM.  For test cases,
it's fine to just use libdrm-intel directly, like what I've done here:

  http://cgit.freedesktop.org/~krh/simple-yuv

and for real use-cases, libva will use libdrm-intel directly.
