Panfrost can skip the reset if TDR has fired before the free-job worker.
Currently, since Panfrost doesn't take any action on these scenarios, the
job is being leaked, considering that `free_job()` won't be called.
To avoid such leaks, inform the scheduler that the job did not actually
timeout and no reset was performed through the new status code
DRM_GPU_SCHED_STAT_NO_HANG.

Xe can skip the reset if TDR has fired before the free job worker and can
also re-arm the timeout timer in some scenarios. Instead of manipulating
scheduler's internals, inform the scheduler that the job did not actually
timeout and no reset was performed through the new status code
DRM_GPU_SCHED_STAT_NO_HANG.
Note that, in the first case, there is no need to restart submission if it
hasn't been stopped.

Etnaviv can skip a hardware reset in two situations:
1. TDR has fired before the free-job worker and the timeout is spurious.
2. The GPU is still making progress on the front-end and we can give
the job a chance to complete.
Instead of manipulating scheduler's internals, inform the scheduler that
the job did not actually timeout and no reset was performed through

When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and allow the timer to be rearmed. This gives long-running jobs
a chance to complete.

As more KUnit tests are introduced to evaluate the basic capabilities of
the `timedout_job()` hook, the test suite will continue to increase in
duration. To reduce the overall running time of the test suite, decrease
the scheduler's timeout for the timeout tests.

When the DRM scheduler times out, it's possible that the GPU isn't hung;
instead, a job just took unusually long (longer than the timeout) but is
still running, and there is, thus, no reason to reset the hardware. This
can occur in two scenarios:
1. The job is taking longer than the timeout, but the driver determined
through a GPU-specific mechanism that the hardware is still making
progress. Hence, the driver would like the scheduler to skip the
timeout and treat the job as still pending from then onward. This
happens in v3d, Etnaviv, and Xe.
2. Timeout has fired before the free-job worker. Consequently, the
scheduler calls `sched->ops->timedout_job()` for a job that isn't
timed out.
These two scenarios are problematic because the job was removed from the
`sched->pending_list` before calling `sched->ops->timedout_job()`, which
means that when the job finishes, it won't be freed by the scheduler
though `sched->ops->free_job()` - leading to a memory leak.
To solve these problems, create a new `drm_gpu_sched_stat`, called
DRM_GPU_SCHED_STAT_NO_HANG, which allows a driver to skip the reset. The
new status will indicate that the job must be reinserted into
`sched->pending_list`, and the hardware / driver will still complete that
job.

Among the scheduler's statuses, the only one that indicates an error is
DRM_GPU_SCHED_STAT_ENODEV. Any status other than DRM_GPU_SCHED_STAT_ENODEV
signifies that the operation succeeded and the GPU is in a nominal state.
However, to provide more information about the GPU's status, it is needed
to convey more information than just "OK".
Therefore, rename DRM_GPU_SCHED_STAT_NOMINAL to
DRM_GPU_SCHED_STAT_RESET, which better communicates the meaning of this
status. The status DRM_GPU_SCHED_STAT_RESET indicates that the GPU has
hung, but it has been successfully reset and is now in a nominal state
again.

By default the GuC starts in the 'native' mode and enables the VGT
mode (aka 'virtualization' mode) only after it receives at least one
set of VF configuration data. While this happens naturally while PF
begins VFs provisioning, we might need this sooner as some actions,
like TLB_INVALIDATION_ALL(0x7002), is supported by the GuC only in
the VGT mode.
And this becomes a real problem if we would want to use above action
to invalidate the LMTT early during VFs auto-provisioning, before VFs
are enabled, as such H2G would be rejected:

This could be mitigated by pushing earlier a PF self-configuration
with some hard-coded values that cover unlimited access to the GGTT,
use of all GuC contexts and doorbells. This step is sufficient for
the GuC to switch into the VGT mode.

As part of the resume or GT reset, the PF driver schedules work
which is then used to complete restarting of the SR-IOV support,
including resending to the GuC configurations of provisioned VFs.
However, in case of short delay between those two actions, which
could be seen by triggering a GT reset on the suspened device:
$ echo 1 > /sys/kernel/debug/dri/0000:00:02.0/gt0/force_reset

There's no need to submit the nop job again on the first queue. Any
state needed is already saved when the first LRC is switched out. The
comment is a little misleading regarding indirect W/A: first of all
there's still no indirect W/A enabled and secondly, even after they are,
there's no need to submit this job again for having their state
propagated: the indirect W/A will actually run on every LRC switch.

Both the nop and wa jobs are going through the same boiler plate calls
to emit the job with a timeout and handling error for both bb and job.
Extract emit_job_sync() so those functions create the bb, handling
possible errors and delegate the part about really emitting the job
and waiting for its completion.

The bb allocation in emit_wa_job() is wrong in 2 ways: first it's
allocating enough space for the 3DSTATE or hardcoding 4k depending on
the engine. In the first case it doesn't account for the WAs and in the
former it may not be sufficient. Secondly it's using the size instead of
number of dwords, causing the buffer to be 4x bigger than needed:
xe_bb_new() receives number of dwords as parameter and its declaration
was also not following its implementation.
Lastly, reword the debug message since it's not only about the LRC WAs
anymore as it also include the 3DSTATE for render.
While it's unlikely this is causing any real issue, let's calculate the
needed space and allocate just enough.

We plan to add more PF and VF types and mixing them in a single

When the GPU scheduler was ported to using a struct for its
initialization parameters, it was overlooked that panfrost creates a
distinct workqueue for timeout handling.
The pointer to this new workqueue is not initialized to the struct,
resulting in NULL being passed to the scheduler, which then uses the
system_wq for timeout handling.
Set the correct workqueue to the init args struct.

In some application scenarios, we hope to get the corresponding
connector when the bridge's detect hook is invoked.
In most cases, we can get the connector by drm_atomic_get_connector_for_encoder
if the encoder attached to the bridge is enabled, however there will
still be some scenarios where the detect hook of the bridge is called
but the corresponding encoder has not been enabled yet. For instance,
this occurs when the device is hot plug in for the first time.
Since the call to bridge's detect is initiated by the connector, passing
down the corresponding connector directly will make things simpler.

Document xe module params with the default values following a similar
strategy for all of them:
1) Define a DEFAULT_* macro with the default value. When the
value can't be directly stringified, also define a *_STR
variant
2) Use __stringify() or the _STR variant to make sure the
default value shows up in the param description
This allows us to show the correct default according to the
configuration. max_vfs for example was wrongly documented for
CONFIG_DRM_XE_DEBUG and svm_notifier_size didn't have its default
documented.

The check would fail if the address is unaligned, but not when
accounting the offset. Instead of `buf | offset` it should have
been `buf + offset`. To make it more readable and also drop the

DRM_NOUVEAU_NVIF command, but ignores the type and direction bits, so any

Check for all the bits except the size that is handled inside of the
handler.
