When remaining resources are being cleaned up on driver close,
outstanding VM mappings may result in resources being leaked, due
to an object reference loop, as shown below, with each object (or
set of objects) referencing the object below it:
PVR GEM Object
GPU scheduler "finished" fence
GPU scheduler “scheduled” fence
PVR driver “done” fence
PVR Context
PVR VM Context
PVR VM Mappings
PVR GEM Object
The reference that the PVR VM Context has on the VM mappings is a
soft one, in the sense that the freeing of outstanding VM mappings
is done as part of VM context destruction; no reference counts are
involved, as is the case for all the other references in the loop.
To break the reference loop during cleanup, free the outstanding
VM mappings before destroying the PVR Context associated with the
VM context.

This adds a linked list of VM contexts which is needed for the next patch
to be able to correctly track VM contexts for destruction on file close.
It is only safe for VM contexts to be removed from the list and destroyed
when not in interrupt context.

Switching to memdup_user(), which combines kmalloc() and copy_from_user(),
and it can simplfy code.

Implement job submission ioctl. Job scheduling is implemented using
drm_sched.
Jobs are submitted in a stream format. This is intended to allow the UAPI
data format to be independent of the actual FWIF structures in use, which
vary depending on the GPU in use.
The stream formats are documented at:
https://gitlab.freedesktop.org/mesa/mesa/-/blob/f8d2b42ae65c2f16f36a43e0ae39d288431e4263/src/imagination/csbgen/rogue_kmd_stream.xml
Changes since v8:
- Updated for upstreamed DRM scheduler changes
- Removed workaround code for the pending_list previously being updated
after run_job() returned
- Fixed null deref in pvr_queue_cleanup_fw_context() for bad stream ptr
given to create_context ioctl
- Corrected license identifiers
Changes since v7:
- Updated for v8 "DRM scheduler changes for XE" patchset
Changes since v6:
- Fix fence handling in pvr_sync_signal_array_add()
- Add handling for SUBMIT_JOB_FRAG_CMD_DISABLE_PIXELMERGE flag
- Fix missing dma_resv locking in job submit path
Changes since v5:
- Fix leak in job creation error path
Changes since v4:
- Use a regular workqueue for job scheduling
Changes since v3:
- Support partial render jobs
- Add job timeout handler
- Split sync handling out of job code
- Use drm_dev_{enter,exit}
Changes since v2:
- Use drm_sched for job scheduling

Implement ioctls for the creation and destruction of contexts. Contexts are
used for job submission and each is associated with a particular job type.
Changes since v8:
- Fixed one error path in pvr_stream_process_1()
- Corrected license identifiers
Changes since v5:
- Fix context release in final error path in pvr_context_create()
Changes since v3:
- Use drm_dev_{enter,exit}
