[Mesa-dev] [PATCH 0/7] Support for samplerExternalOES YUV EGLImages

[Kristian Høgsberg]

From: Kristian Høgsberg Kristensen <krh at bitplanet.net>

This patche series adds support for importing YUV buffers as EGLImages
and sampling from them using samplerExternalOES. This series
implements the sampling by lowering the texture operation to 1-3
texture operations from the YUV planes and inserts color space
conversion in the shader.

Kristian Høgsberg Kristensen (7):
  nir: Add new 'plane' texture source type
  nir: Add a lowering pass for YUV textures
  i965: Create multiple miptrees planar YUV images
  i965: Support textures with multiple planes
  i965: Invoke lowering pass for YUV textures
  i965: Allow creating planar YUV __DRIimages
  dri: Add YVU formats
