[Intel-gfx] [PATCH xf86-video-intel v7 2/2] sna: Added AYUV format support for textured and sprite video adapters.
Stanislav Lisovskiy
stanislav.lisovskiy at intel.com
Fri Nov 9 14:14:40 UTC 2018
v2: Renamed DRM_FORMAT_XYUV to DRM_FORMAT_XYUV8888.
Added comment about AYUV byte ordering in Gstreamer.
v3: Removed sna_composite_op flags related change to the separate patch.
v4: Fixed review comments, done code refactoring
v5: Fixed following review comments:
- Fixed comment in shader code for ayuv kernel.
- Fixed naming to VIDEO_AYUV_BT601/BT709 for ayuv kernels.
- Removed duplicate gen9_kernel parameter, left from previous patches
- Added colorspace handling for new AYUV kernel
- Fixed naming of sna_copy_packed_data_ayuv to sna_copy_ayuv_data
- Started using standard bswap_32 function for byte swapping in sna_copy_ayuv_data
- Removed redundant code in sna_copy_ayuv_data so that it looks more neat
- Fixed XVIMAGE_AYUV structure initialization to contain proper byte sequence for GST
- Fixed bogus comment about subsampling for DRM_FORMAT_XYUV8888
- Fixed AYUV advertisement for all platforms
- Removed unnecessary RGB888 declaration.
v6:
- Fixed surface format not to use alpha as supposed
- Now doing byte swapping always during copy
- Changed hack, required for GST to work to be at one place
- Fixed invalid sampling values for XVIMAGE_AYUV
- Fixed sprite format checking order and images_ayuv definition.
v7:
- Removed reverse_bytes bool parameter, now swapping bytes
for XYUV unconditionally both for textured and sprite modes.
