No. This way the driver would announce availability of NV12 even on
chipsets where NV12 is not supported for the writeback. Please define
separate formats array.
BTW: does HW only support NV12 for the writeback? What about YV12 or e.g. NV21?
Yes, as we discussed in the prev patch, I will split the wb2_formats
array to RGB only and RGB+YUV to address this issue.
Regarding the full list of supported formats, here it is:
https://git.codelinaro.org/clo/la/platform/vendor/opensource/display-drivers/-/blob/clo/main/msm/sde/sde_hw_catalog_format.h?ref_type=heads#L107
But YUV420 shouldnt be here as its not supported.
I have to see if I can add some test cases in IGT to validate NV16 and
DRM_FORMAT_YUYV. Hence I only exposed this one for now.
