I had tried to add YUYV support to dri image(to support overlay),
however Kristian enabled YUYV as a special planar YUV for wayland
(two planes which are overlaped).
so I try to follow it and pick up the useful part in my previous patches.
- add tiling support for bo update (from user data)
- add shared_handle (global region name) in gbm
- add YUYV support in gbm
- test case to render XRGB or YUYV buffer to weston
my understanding of current YUV buffer support in mesa is: it can interpret a
YUV buffer,
not how to create such buffer. it make me a little nervous to add YUYV to
gbm since there is no such format in dri image yet (though there is
WL_DRM_FORMAT_YUYV
for wayland buffer); I just try to use __DRI_IMAGE_FORMAT_GR88 instead to make
sure it
create buffer with same size.
so, one point I want to seek your comments are:
should we consider YUYV buffer allocation in mesa/gbm?
should we still need a YUYV format for dri image?
thanks.
