Hello all,
Recently, I meet a performance problem with drmModeSetPlane(), it
works quite slow with drm_atomic_commit(), I have to force it use
drm_atomic_async_commit() for drmModeSetPlane() which modifies the drm
base system. I want to optimize the performance in standard way, so I
think I could move those sync job to one of drmWaitVBlank() or
drmModePageFlip.
But I found most of atomic_commit() would have a sync internal,
waiting vbank. So those functions like drmWaitVBlank() or
drmModePageFlip are not necessary after drmModeSetPlane()?
