2023-02-15drm/amd/display: disable SubVP + DRR to prevent underflowAurabindo Pillai
[Why&How] Temporarily disable SubVP+DRR since Xorg has an architectural limitation where freesync will not work in a multi monitor configuration. SubVP+DRR requires that freesync be working. Whether OS has variable refresh setting enabled or not, the state on the crtc remains same unless an application requests VRR. Due to this, there is no way to know whether freesync will actually work or not while we are on the desktop from the kernel's perspective. If userspace does not have a limitation with multi-display freesync (for example wayland), then this feature can be enabled by adding a dcfeaturemask option to amdgpu on the kernel cmdline like: amdgpu.dcfeaturemask=0x200 Signed-off-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Reviewed-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-12-15drm/amd/display: run subvp validation with supported vlevelDillon Varone
[WHY] Subvp portion validation currently assumes that if vlevel provided does not support pstate, then none will, and so subvp is not used. [HOW] After get vlevel, use lowest vlevel that supports pstate if it exists, and use that for subvp validation.

[Why] Iterating over every voltage state when we need to validate thousands of configurations all at once (i.e. display hotplug) can take a significant amount of time. [How] Check just the highest voltage state when fast_validate is true to verify whether the configuration can work at all, then do a proper validation including all voltage states later when fast_validate is false.
