It's impressive how specific power management and soft reset issues were resolved while transitioning the 10-year-old AMD GCN 1.0/1.1 graphics card to the latest AMDGPU driver. With AMD not significantly expanding official support, it's interesting to see how Valve took the lead in identifying and addressing these problems, highlighting how much driver optimization can be driven by the community. It would also be worthwhile to verify how reliably these improvements operate across various Linux environments.
