Subject: [PATCH 0/3] Support mclk switching when monitors are in sync
Date: Thu, 22 Aug 2019 10:36:42 -0500 [thread overview]
Message-ID: <20190822153645.3296-1-alexander.deucher@amd.com> (raw)
This patch set enables mclk switching with multiple monitors when all
monitors are sync. Normally mclk switching is not available with
multiple monitors because the vblank timing does not line up. However,
if the timing is identical, the display driver can sync up the displays
in some cases. Check for these cases and allow mclk switch when
possible.

drm/amdgpu/powerplay/smu7: enable mclk switching if monitors are
synced
drm/amdgpu/powerplay/vega10: enable mclk switching if monitors are
synced
drm/amd/display: update bw_calcs to take pipe sync into account (v2)
