[PATCH 3/3] drm/msm/mdp5: Disable pingpong autorefresh at tearcheck init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxxx>

If pp autorefresh is up (from bootloader splash), we will surely get
vblank and pp timeouts.  Ensure it is turned off.
