Subject: [PATCH] drm/vc4: Fix synchronization firmwarekms against GL
|
|
rendering.
|
|
|
|
We would present the framebuffer immediately without waiting for
|
|
rendering to finish first, resulting in stuttering and flickering as a
|
|
window was dragged around when the GPU was busy enough to not just win
|
|
the race.
