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.
Boris Brezillon (5):
drm/panfrost: Add job slot register defs for affinity
drm/panfrost: Introduce uAPI for JM context creation
drm/panfrost: Introduce JM context for manging job resources
drm/panfrost: Expose JM context IOCTLs to UM
drm/panfrost: Display list of device JM contexts over debugfs
