[PATCH xf86-video-amdgpu 8/9] Move DPMS check from amdgpu_scanout_do_update to amdgpu_scanout_flip

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

 



From: Michel Dänzer <michel.daenzer@xxxxxxx>

When amdgpu_scanout_do_update is called from
drmmode_crtc_scanout_update, drmmode_crtc->pending_dpms_mode may still
be != DPMSModeOn, e.g. during server startup.

Fixes intermittently showing garbage with TearFree enabled.

(Ported from radeon commit cc9d6b7db9c2078be1e530a64af6d517c6a42024)
