[PATCH v2 0/4] Introduce Panfrost JM contexts

[Adrián Larumbe]

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, but at the moment that includes priorities only.

There's a MR for a Mesa commit series that makes use of these changes:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/37075

Changelog:

v2:
 - Core and L2 cache affinities are not longer part of the context uAPI
 - Individual JS priorites are no longer possible, and the same context
 priority is applied onto all the JS and scheduler entities.
 - Minor changes in the debugfs knob to reflect all the above.

Boris Brezillon (4):
  drm/panfrost: Introduce uAPI for JM context creation
  drm/panfrost: Introduce JM contexts for manging job resources
  drm/panfrost: Expose JM context IOCTLs to UM
  drm/panfrost: Display list of device JM contexts over debugfs
