PCI IDs for XEHPSDV were never added and platform always marked with
force_probe. Drop what's not used and rename some places to either be
xehp or dg2, depending on the platform/IP checks.
The registers not used anymore are also removed.

The must-have part of the documentation was already added to the existing

are currently active in the community. None of those discussion should

Current drm-xe-next doesn't have any drm/scheduler patch that is not

the relationship between drm_gpu_scheduler and drm_sched_entity.

No DRM scheduler changes required, drivers just return NULL in run_job
vfunc.
The rough consensus is that no helper or extra scaffolding is needed
around long-running jobs and no further changes to drm-scheduler.
At least for now. Other drivers that currently do long-running workloads
have no plat to use drm-scheduler. Besides, the current consensus is
that this solution of simply returning NULL to the run_job function should
work without extra code duplication or complication.
On top of that, this item was already a non-blocking one for upstreaming Xe,
so let's move that to the 'Completed' section and revisit the long-running
solution as a community after Xe is integrated in DRM.

Let’s establish a merge plan for Xe, by writing down clear pre-merge goals, in
order to avoid unnecessary delays.
This initial document starts with a TODO list containing items with clear and
measurable key results. Xe’s initial pull request should only be sent to
dri-devel after all the items are clearly resolved.
Since many of them involve some level of a community consensus, in many cases,
the consensus will be reached in follow-up patches to this document with more
details of the API or helpers that will be developed or modified.
Besides of the items that are highlighted in this document, it is important
to highlight that Oded, has been volunteered to give the overall ack on Xe
driver as the way to confirm that it looks good for upstream.
v2: Incorporated Daniel's feedback:
- Do not make long-running compute a blocker.
- Add a mention to drm-exec that that ties to vm_bind and long-running
compute jobs. Then I also added GPUVA since I recently noticed that this
ties also to the work Matt is doing on that front.
- Added the devcoredump section.
- Add the mention to Oded being volunteered for the overall ack.
v3: Reword a bit the Async VM_BIND to incorporate Daniel's feedback on ensuring
the async vmbind consensus explicitly include Mesa, besides other kernel
drivers.
