Subject: [PATCH] HACK: MTK: Disable AFBC support
|
|
|
|
Starting with Mesa 25 AFBC will get more eagerly used. Unfortunately it
|
|
seems both primary and overlay planes on Genio 700 and Genio 1200 are
|
|
broken in this regard. On 1200 it results in odd corrupted frames, while
|
|
on 700 it results in vblank timeouts (for primary planes)
|
|
|
|
Add a HACK to disable AFBC for now until this can be further diagnosed
