From ecd6fce2611e88ff8468a354cff8eda39f260a31 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 31 Aug 2016 17:44:01 -0400 Subject: mesa/st: support lowering multi-planar YUV 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: https://lists.freedesktop.org/archives/mesa-dev/2016-September/127832.html They all seemed worse than pipe_resource::next Signed-off-by: Rob Clark --- src/gallium/include/pipe/p_state.h | 6 ++++++ src/gallium/include/state_tracker/st_api.h | 3 +++ 2 files changed, 9 insertions(+) (limited to 'src/gallium/include') diff --git a/src/gallium/include/pipe/p_state.h b/src/gallium/include/pipe/p_state.h index ebd03379e94..415ea85a2ad 100644 --- a/src/gallium/include/pipe/p_state.h +++ b/src/gallium/include/pipe/p_state.h @@ -498,6 +498,12 @@ struct pipe_resource unsigned bind; /**< bitmask of PIPE_BIND_x */ unsigned flags; /**< bitmask of PIPE_RESOURCE_FLAG_x */ + + /** + * For planar images, ie.
