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.
