I have a fairly new monitor that requires Display Stream Compression (DSC) support to run at a high refresh rate with a high resolution.
To achieve such refresh rate, the GPU needs to support DSC.
The AMDGPU driver supposedly has support for DSC.
DSC initialization fails on my system and I cannot use the monitor unless I lower the refresh rate down to 60hz at ~4k.
I know my GPU supports DSC and this monitor as it works on Windows™ /shrug
I wonder whether the options enabled by this PR would resolve the issue?
