The must-have part of the documentation was already added to the existing
/gpu/drm-vm-bind-async. The other extra discussion around GPUVM helpers
are currently active in the community. None of those discussion should
block Xe since documentation, specially around locking was completed in
a community consensus.

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.

To be used by drivers that do per-buffer (e.g: virtio-gpu) uploads (rather

That way, these drivers could force a full plane update if the framebuffer

Currently, job flow control is implemented simply by limiting the number
of jobs in flight. Therefore, a scheduler is initialized with a credit
limit that corresponds to the number of jobs which can be sent to the
hardware.
This implies that for each job, drivers need to account for the maximum
job size possible in order to not overflow the ring buffer.
However, there are drivers, such as Nouveau, where the job size has a
rather large range. For such drivers it can easily happen that job
submissions not even filling the ring by 1% can block subsequent
submissions, which, in the worst case, can lead to the ring run dry.
In order to overcome this issue, allow for tracking the actual job size
instead of the number of jobs. Therefore, add a field to track a job's
credit count, which represents the number of credits a job contributes
to the scheduler's credit limit.

The drm-stats fdinfo tags made available to user space are drm-engine,
drm-cycles, drm-max-freq and drm-curfreq, one per job slot.
This deviates from standard practice in other DRM drivers, where a single
set of key:value pairs is provided for the whole render engine. However,
Panfrost has separate queues for fragment and vertex/tiler jobs, so a
decision was made to calculate bus cycles and workload times separately.
Maximum operating frequency is calculated at devfreq initialisation time.
Current frequency is made available to user space because nvtop uses it
when performing engine usage calculations.
It is important to bear in mind that both GPU cycle and kernel time numbers
provided are at best rough estimations, and always reported in excess from
the actual figure because of two reasons:
- Excess time because of the delay between the end of a job processing,
the subsequent job IRQ and the actual time of the sample.
- Time spent in the engine queue waiting for the GPU to pick up the next
job.
To avoid race conditions during enablement/disabling, a reference counting
mechanism was introduced, and a job flag that tells us whether a given job
increased the refcount. This is necessary, because user space can toggle
cycle counting through a debugfs file, and a given job might have been in
flight by the time cycle counting was disabled.
The main goal of the debugfs cycle counter knob is letting tools like nvtop
or IGT's gputop switch it at any time, to avoid power waste in case no
engine usage measuring is necessary.
Also add a documentation file explaining the possible values for fdinfo's
engine keystrings and Panfrost-specific drm-curfreq-<keystr> pairs.

Pull drm ci scripts from Dave Airlie:
"This is a bunch of ci integration for the freedesktop gitlab instance
where we currently do upstream userspace testing on diverse sets of
GPU hardware. From my perspective I think it's an experiment worth
going with and seeing how the benefits/noise playout keeping these
files useful.
Ideally I'd like to get this so we can do pre-merge testing on PRs
eventually.
Below is some info from danvet on why we've ended up making the
decision and how we can roll it back if we decide it was a bad plan.
Why in upstream?
- like documentation, testcases, tools CI integration is one of these
things where you can waste endless amounts of time if you
accidentally have a version that doesn't match your source code
- but also like the above, there's a balance, this is the initial cut
of what we think makes sense to keep in sync vs out-of-tree,
probably needs adjustment
- gitlab supports out-of-repo gitlab integration and that's what's
been used for the kernel in drm, but it results in per-driver
fragmentation and lots of duplicated effort. the simple act of
smashing an arbitrary winner into a topic branch already started
surfacing patches on dri-devel and sparking good cross driver team
discussions
Why gitlab?
- it's not any more shit than any of the other CI
- drm userspace uses it extensively for everything in userspace, we
have a lot of people and experience with this, including
integration of hw testing labs
- media userspace like gstreamer is also on gitlab.fd.o, and there's
discussion to extend this to the media subsystem in some fashion
Can this be shared?
- there's definitely a pile of code that could move to scripts/ if
other subsystem adopt ci integration in upstream kernel git. other
bits are more drm/gpu specific like the igt-gpu-tests/tools
integration
- docker images can be run locally or in other CI runners
Will we regret this?
- it's all in one directory, intentionally, for easy deletion
- probably 1-2 years in upstream to see whether this is worth it or a
Big Mistake. that's roughly what it took to _really_ roll out solid
CI in the bigger userspace projects we have on gitlab.fd.o like
mesa3d"

The consensus is for individual drivers VM_BIND uapis with
the GPUVA helpers that are already implemented and merged
upstream.
The merged GPUVA documentation also establish some overall
rules for the locking to be followed by the drivers.
