[PATCH xf86-video-amdgpu 05/10] Wait for pending flips synchronously before turning off a CRTC
Michel Dänzer
michel at daenzer.net
Fri Aug 18 08:53:17 UTC 2017
From: Michel Dänzer <michel.daenzer at amd.com>
Allows removing drmmode_clear_pending_flip and the pending_dpms_mode
field and cleaning up the code considerably.
(Ported from radeon commit e6d7dc2070f4d21a6900916bb70a31839112882c)
