This is a RFC series to implement usermode graphics queues for AMDGPU driver (Navi 3X and above). The idea of usermode graphics queue is to allow direct workload submission from a userspace graphics process who has amdgpu graphics context. Once we have some initial feedback on the design, we will publish a follow up V1 series with a libdrm consumer test.
