Revert "drm/amd/display: disable SubVP + DRR to prevent underflow"

[ Upstream commit f38129bb081758176dd78304faaee95007fb8838 ] This reverts commit 80c6d6804f31451848a3956a70c2bcb1f07cfcb0. The orignal commit was intended as a workaround to prevent underflow and flickering when using one normal monitor and the other high refresh rate monitor (> 120Hz). This patch is being reverted in favour of a software solution to enable SubVP+DRR Signed-off-by: Aurabindo Pillai Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amd/display: disable SubVP + DRR to prevent underflow

2023-02-16T03:26:22+00:00

[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 Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Deucher
