mesa/st: support lowering multi-planar YUV

Graphics / Mesa 3D Graphics Library / Mesa - Rob Clark [gmail.com] - 26 September 2016 14:29 UTC

Support multi-planar YUV for external EGLImage's (currently just in the dma-buf import path) by lowering to multiple texture fetch's for each plane and CSC in shader.

There was some discussion of alternative approaches for tracking the additional UV or U/V planes:

They all seemed worse than pipe_resource::next
