throttling. So make the query function globally accessible.
v2: Revert include order change (review feedback from Lucas)
v3: Remove '_sysfs' from throttle file names and keep limit query in

Rodrigo).
v4: Correct #include while renaming header file (review feedback

This error capture prints into dmesg HW state when a gpu hang happens.
It was useful when we did not had devcoredump, now it is a incompleted

Now that we eliminated all the mem_access get/put with its
locking issues from the inner calls of migration, we can
allow D3Cold.
Enable it when VRAM utilization is lower then 300Mb. On
higher utilization we only allow D3hot so we don't increase
so much the latency on runtime resume due to the memory
restoration.

GuC reset status is not reliable for this purpose and it is
once in a while ending up in a situation of D3Cold, where
power_reset is false and without the proper memory restoration
the GuC reload and Display will fail to come back from D3Cold.
So, let's do a full restoration of everything if we have a risk
of losing power, without further optimizations.

Prepare power-well and DC handling for a full power
lost during D3Cold, then sanitize it upon D3->D0.
Otherwise we get a bunch of state mismatch.
Ideally we could leave DC9 enabled and wouldn't need
to move DC9->DC0 on every runtime resume, however,
the disable_DC is part of the power-well checks and
intrinsic to the dc_off power well. In the future that
can be detangled so we can have even bigger power savings.
But for now, let's focus on getting a D3Cold, which saves
much more power by itself.
v2: create new functions to avoid full-suspend-resume path,
which would result in a deadlock between xe_gem_fault and the
modeset-ioctl.
v3: Only avoid the full modeset to avoid the race, for a more

In the regular use case scenario, user space will create a
VM, and keep it alive for the entire duration of its workload.
For the regular desktop cases, it means that the VM
is alive even on idle scenarios where display goes off. This
is unacceptable since this would entirely block runtime PM
indefinitely, blocking deeper Package-C state. This would be
a waste drainage of power.
Limit the VM protection solely for long-running workloads that
are not protected by the scheduler references.
By design, run_job for long-running workloads returns NULL and
the scheduler drops all the references of it, hence protecting
the VM for this case is necessary.
v2: Update commit message to a more imperative language and to
reflect why the VM protection is really needed.
Also add a comment in the code to let the reason visbible.
v3: Remove vma_access case and the mentions to mmap. Mmap cases
are already protected by the gem page fault.

Here we are using drmm to ensure we release the coredump when unloading
the module, however the coredump is very much tied to the struct device
underneath. We can see this when we hotunplug the device, for which we
have already got a coredump attached. In such a case the coredump still
remains and adding another is not possible. However we still register
the release action via xe_driver_devcoredump_fini(), so in effect two or
more releases for one dump. The other consideration is that the
coredump state is embedded in the xe_driver instance, so technically
once the drmm release action fires we might free the coredumpe state
from a different driver instance, assuming we have two release actions
and they can race. Rather use devm here to remove the coredump when the
device is released.

This is quite broken since we are nuking the pdev link to the private
driver struct, but note here that driver_release is called when the
drm_device is released (poor mans drmm), which can be long after the
device has been removed. So here what we are actually doing is nuking
the pdev link for what is potentially bound to a different drm_device.
If that happens before our pci remove callback is triggered (for the new
drm_device) we silently exit and skip some important cleanup steps,
resulting in hilarity.
There should be no reason to implement driver_release, when we already
have nicer stuff like drmm, so just remove completely. The actual pdev
link is already nuked when removing the device.

Print the accumulated runtime for client when printing fdinfo.
Each time a query is done it first does 2 things:
1) loop through all the exec queues for the current client and
accumulate the runtime, per engine class. CTX_TIMESTAMP is used for
that, being read from the context image.
2) Read a "GPU timestamp" that can be used for considering "how much GPU
time has passed" and that has the same unit/refclock as the one
recording the runtime. RING_TIMESTAMP is used for that via MMIO.
Since for all current platforms RING_TIMESTAMP follows the same
refclock, just read it once, using any first engine available.
This is exported to userspace as 2 numbers in fdinfo:
drm-cycles-<class>: <RUNTIME>
drm-total-cycles-<class>: <TIMESTAMP>
Userspace is expected to collect at least 2 samples, which allows to
know the client engine busyness as per:
RUNTIME1 - RUNTIME0
busyness = ---------------------
T1 - T0
Since drm-cycles-<class> always starts at 0, it's also possible to know
if and engine was ever used by a client.
It's expected that userspace will read any 2 samples every few seconds.
Given the update frequency of the counters involved and that
CTX_TIMESTAMP is 32-bits, the counter for each exec_queue can wrap
around (assuming 100% utilization) after ~200s. The wraparound is not
perceived by userspace since it's just accumulated for all the
exec_queues in a 64-bit counter) but the measurement will not be
accurate if the samples are too far apart.
This could be mitigated by adding a workqueue to accumulate the counters
every so often, but it's additional complexity for something that is
done already by userspace every few seconds in tools like gputop (from
igt), htop, nvtop, etc, with none of them really defaulting to 1 sample
per minute or more.

gt->info.engine_mask used to indicate the available engines, but that
is not always true anymore: some engines are reserved to kernel and some
may be exposed as a single engine (e.g. with ccs_mode).
Runtime changes only happen when no clients exist, so it's safe to cache
the list of engines in the gt and update that when it's needed. This
will help implementing per client engine utilization so this (mostly
constant) information doesn't need to be re-calculated on every query.

Add a helper to accumulate per-client runtime of all its
exec queues. This is called every time a sched job is finished.
v2:
- Use guc_exec_queue_free_job() and execlist_job_free() to accumulate
runtime when job is finished since xe_sched_job_completed() is not a
notification that job finished.
- Stop trying to update runtime from xe_exec_queue_fini() - that is
redundant and may happen after xef is closed, leading to a
use-after-free
- Do not special case the first timestamp read: the default LRC sets
CTX_TIMESTAMP to zero, so even the first sample should be a valid
one.
