2021-02-26drm/amd/display: Add module parameter for freesync video modeAurabindo Pillai
[Why] This option shall be opt-in by default since it is a temporary solution until long term solution is agreed upon which may require userspace interface changes. This feature give the user a seamless experience when freesync aware programs (media players for instance) switches to a compatible freesync mode when playing videos. Enabling this feature also have the potential side effect of causing higher power consumption due to running a mode with lower resolution and base clock frequency with the highest base clock supported on the monitor as per its advertised modes. There has been precedent of manufacturing modes in the kernel. In AMDGPU, the existing usage are for common modes and scaling modes. Other driver have a similar approach as well. [How] Adds a module parameter to enable freesync video mode modeset optimization. Enabling this mode allows the driver to skip a full modeset when a freesync compatible mode is requested by the userspace. This parameter will also add some additional modes that are within the connected monitor's VRR range corresponding to common video modes, which media players can use for a seamless experience while making use of freesync.
