[igt-dev] [PATCH i-g-t 1/3] lib/igt_fb: Add support for Y21x formats as well, v3.
Maarten Lankhorst
maarten.lankhorst at linux.intel.com
Thu Mar 28 18:08:43 UTC 2019
Those formats are packed like YUYV, but only 16 bits per component.
Changes since v1:
- Rebase on top of upstream YUV changes.
Changes since v2:
- Use drm_fourcc.h from upstream.
