linux.git/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_crtc.h, branch v7.0 Linux kernel source tree drm/amd/display: Disable replay and psr while VRR is enabled 2025-01-13T19:21:36+00:00 Tom Chung chiahsuan.chung@amd.com 2024-12-05T15:20:45+00:00 67edb81d6e9af43a0d58edf74630f82cfda4155d [Why] Replay and PSR will cause some video corruption while VRR is enabled. [How] 1. Disable the Replay and PSR while VRR is enabled. 2. Change the amdgpu_dm_crtc_vrr_active() parameter to const. Because the function will only read data from dm_crtc_state.

[Why]
The amdgpu_dm file contains most of the code that works as an interface
between DRM API and DC. As a result, this file becomes very large since
it comprises multiple abstractions such as CRTC manipulation.

[How]
This commit extracts the CRTC code to its specific file named
amdgpu_dm_crtc. This change does not change anything inside the
functions; the only exception is converting some static functions to a
global function.
