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

[Zhao, Halley]

Hi Kristian:
These changes mostly work for wayland-drm, do you think we'd better have this
simple test for wayland-drm?

If yes, do you have better idea to create YUYV buffer from gbm? Or just let it
be to use GR88 to get buffer with same size.

Thanks
