This patch series brings the notion of JM contexts into Panfrost. UM will be able to create contexts, get a handle for them and attach it to a job submission. Contexts describe basic HW resource assignment to jobs, and also their job slot priorities.
A Mesa MR with UM changes that leverage this new kernel driver feature is still in the making.
