[Mesa-dev] [PATCH 6/8] egl: definitions for EXT_image_dma_buf_import

Tue Apr 16 03:45:05 PDT 2013


As specified in:

http://www.khronos.org/registry/egl/extensions/EXT/EGL_EXT_image_dma_buf_import.txt

Checking for the valid fourcc values is left for drivers avoiding
dependency to drm header files here.
