[RFC 0/7] RFC: Usermode queue for AMDGPU driver

[Shashank Sharma]

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.
