The function is only used from within GEM_BUG_ON(), which is causing
warnings with Wunneeded-internal-declaration in some builds. Since the
function is a simple wrapper around a CT function, we can just call the
CT function directly instead.

These two arrays are populated with data read from the I2C device
through regmap_read(), and the data is then compared with hardcoded
vendor/product ID values of supported chips.
However, the return value of regmap_read() was never checked. This is
fine, as long as the two arrays are zero-initialized, so that we don't
compare the vendor/product IDs against whatever garbage is left on the
stack.
Address this issue by zero-initializing these two arrays.

The code was making a copy of a struct ttm_resource. However,
recently the struct ttm_resources were allowed to be subclassed and
also were allowed to be malloced, hence the driver could end up assuming
the copy we handed it was subclassed and worse, the original could have
been freed at this point.
Fix this by using the original struct ttm_resource before it is
potentially freed in ttm_bo_move_sync_cleanup()

Due to high latency in PCIE clock switching on RKL platforms,
switching the PCIE clock dynamically at runtime can lead to HDMI/DP
audio problems. On newer asics this is handled in the SMU firmware.
For SMU7-based asics, disable PCIE clock switching to avoid the issue.
AMD provide a parameter to disable PICE_DPM.
modprobe amdgpu ppfeaturemask=0xfff7bffb
It's better to contorl PCIE_DPM in amd gpu driver,
switch PCI_DPM by determining intel RKL platform for SMU7-based asics.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
The "Board Parameters" members of the structs:
struct atom_smc_dpm_info_v4_5
struct atom_smc_dpm_info_v4_6
struct atom_smc_dpm_info_v4_7
struct atom_smc_dpm_info_v4_10
are written to the corresponding members of the corresponding PPTable_t
variables, but they lack destination size bounds checking, which means
the compiler cannot verify at compile time that this is an intended and
safe memcpy().
Since the header files are effectively immutable[1] and a struct_group()
cannot be used, nor a common struct referenced by both sides of the
memcpy() arguments, add a new helper, amdgpu_memcpy_trailing(), to
perform the bounds checking at compile time. Replace the open-coded
memcpy()s with amdgpu_memcpy_trailing() which includes enough context
for the bounds checking.
"objdump -d" shows no object code changes.

There's only one exclusive slot, and we must not break the ordering.
Adding a new exclusive fence drops all previous fences from the
dma_resv. To avoid violating the signalling order we err on the side of
over-synchronizing by waiting for the existing fences, even if
userspace asked us to ignore them.
A better fix would be to us a dma_fence_chain or _array like e.g.
amdgpu now uses, but
- msm has a synchronous dma_fence_wait for anything from another
context, so doesn't seem to care much,
- and it probably makes sense to lift this into dma-resv.c code as a
proper concept, so that drivers don't have to hack up their own
solution each on their own.

Just deletes some code that's now more shared.
Note that thanks to the split into drm_sched_job_init/arm we can now
easily pull the _init() part from under the submission lock way ahead
where we're adding the sync file in-fences as dependencies.
v2: Correctly clean up the partially set up job, now that job_init()
and job_arm() are apart (Emma).
v3: Rebased over renamed functions for adding depdencies

I found a few too many things that are tricky and not documented, so I
started typing.
I found a few more things that looked broken while typing, see the
varios FIXME in drm_sched_entity.
Also some of the usual logics:
- actually include sched_entity.c declarations, that was lost in the
move here: 620e762f9a98 ("drm/scheduler: move entity handling into
separate file")
- Ditch the kerneldoc for internal functions, keep the comments where
they're describing more than what the function name already implies.
- Switch drm_sched_entity to inline docs.

Originally a job was only bound to the queue when we pushed this, but
now that's done in drm_sched_job_init, making that parameter entirely
redundant.
Remove it.
The same applies to the context parameter in
lima_sched_context_queue_task, simplify that too.
v2:
Rebase on top of msm adopting drm/sched

Instead of just a callback we can just glue in the gem helpers that
panfrost, v3d and lima currently use. There's really not that many
ways to skin this cat.
v2/3: Rebased.
v4: Repaint this shed. The functions are now called _add_dependency()
and _add_implicit_dependency()

It might be good enough on x86 with just READ_ONCE, but the write side
should then at least be WRITE_ONCE because x86 has total store order.
It's definitely not enough on arm.
Fix this proplery, which means
- explain the need for the barrier in both places
- point at the other side in each comment
Also pull out the !sched_list case as the first check, so that the
code flow is clearer.
While at it sprinkle some comments around because it was very
non-obvious to me what's actually going on here and why.
Note that we really need full barriers here, at first I thought
store-release and load-acquire on ->last_scheduled would be enough,
but we actually requiring ordering between that and the queue state.
v2: Put smp_rmp() in the right place and fix up comment (Andrey)

Originally drm_sched_job_init was the point of no return, after which
drivers really should submit a job. I've split that up, which allows
us to fix this issue pretty easily.
Only thing we have to take care of is to not skip to error paths after
that. Other drivers do this the same for out-fence and similar things.
v2: It's not really a bugfix, just an improvement, since all
drm_sched_job_arm does is reserve the fence number. And gaps should be
fine, as long as the drm_sched_job doesn't escape anywhere at all.
For robustness it's still better to align with other drivers here and
not bail out after job_arm().
v3: I misplaced drm_sched_job_arm by _one_ line! Thanks to Rob for
testing and debug help.

This is a very confusingly named function, because not just does it
init an object, it arms it and provides a point of no return for
pushing a job into the scheduler. It would be nice if that's a bit
clearer in the interface.
But the real reason is that I want to push the dependency tracking
helpers into the scheduler code, and that means drm_sched_job_init
must be called a lot earlier, without arming the job.
v2:
- don't change .gitignore (Steven)
- don't forget v3d (Emma)
v3: Emma noticed that I leak the memory allocated in
drm_sched_job_init if we bail out before the point of no return in
subsequent driver patches. To be able to fix this change
drm_sched_job_cleanup() so it can handle being called both before and
after drm_sched_job_arm().
Also improve the kerneldoc for this.
v4:
- Fix the drm_sched_job_cleanup logic, I inverted the booleans, as
usual (Melissa)
- Christian pointed out that drm_sched_entity_select_rq() also needs
to be moved into drm_sched_job_arm, which made me realize that the
job->id definitely needs to be moved too.
Shuffle things to fit between job_init and job_arm.
v5:
Reshuffle the split between init/arm once more, amdgpu abuses
drm_sched.ready to signal gpu reset failures. Also document this
somewhat. (Christian)
v6:
Rebase on top of the msm drm/sched support. Note that the
drm_sched_job_init() call is completely misplaced, and hence also the
split-out drm_sched_entity_push_job(). I've put in a FIXME which the next
patch will address.
v7: Drop the FIXME in msm, after discussions with Rob I agree it shouldn't
be a problem where it is now.
