Subject: [PATCH 0902/1085] vc4/hvs: Fix lbm size calculation for yuv
|
|
|
|
The code was reducing the number of components by one when we were not
|
|
blending with alpha. But that only makes sense if the components include
|
|
alpha.
|
|
|
|
For YUV, we were reducing the number of components for Y from one to zero
|
|
which resulted in no lbm space being allocated.
