Subject: [PATCH] drm/vc4: plane: Increase UPM allocation size for YUV444
|
|
|
|
YUV444 support isn't officially supported by the hardware, but
|
|
worked if you told it the image was YUV422 with double the width
|
|
and altered chroma scaling.
|
|
|
|
Adding BCM2712 support gained a fetcher memory (UPM). The code
|
|
handling UPM allocations didn't have a case for YUV444, so only
|
|
allocated based on the base width, and therefore underflowed.
|
|
|
|
Increase the UPM allocation size for the luma plane of YUV444
|
|
to match.
|
|
|
