Currently, queue is updated with data in queue_properties.
And all allocated resource in queue_properties will not
be freed until the queue is destroyed.
But some properties(e.g., cu mask) bring some memory
management headaches(e.g., memory leak) and make code
complex. Actually they have been copied to mqd and
don't have to persist in queue_properties.
Add an argument into update queue to pass such properties,
then we can remove them from queue_properties.

[WHY]
On certain configs, SMU clock table voltages don't match which cause parser
to behave incorrectly by leaving dcfclk and socclk table entries unpopulated.
[HOW]
Currently the function that finds the corresponding clock for a given voltage
only checks for exact voltage level matches. In the case that no match gets
found, parser now falls back to searching for the max clock which meets the
requested voltage (i.e. its corresponding voltage is below requested).

tl;dr ChromeOS uses the atomic interface for everything except the cursor. This
is incorrect and forces amdgpu to disable some hardware features. Let's revert
the ChromeOS-specific workaround in mainline and allow the Chrome team to keep
it internally in their own tree.
See [1] for more details. This patch is an alternative to [2], which added
ChromeOS detection.

[Why]
When rapidly plugging and unplugging a DP sink, detection link
training can be mistakenly skipped.
This is due to the hotplug processing occurring before the
encoder assignment logic has had a chance to process the removal
of a stream. The encoder that would be used for detection link
training is then erroneously reported as already in use and
detection link training is skipped.
[How]
During hot plug processing, only determine a link encoder to be
unavailable for a particular link if it has been assigned to a
different link.

This fix the deadlock with the BO reservations during SVM_BO evictions
while allocations in VRAM are concurrently performed. More specific,
while the ttm waits for the fence to be signaled (ttm_bo_wait), it
already has the BO reserved. In parallel, the restore worker might be
running, prefetching memory to VRAM. This also requires to reserve the
BO, but blocks the mmap semaphore first. The deadlock happens when the
SVM_BO eviction worker kicks in and waits for the mmap semaphore held
in restore worker. Preventing signal the fence back, causing the
deadlock until the ttm times out.
We don't need to hold the BO reservation anymore during validation
and mapping. Now the physical addresses are taken from hmm_range_fault.
We also take migrate_mutex to prevent range migration while
validate_and_map update GPU page table.

result in an infinite loop of link training to occur in
dp_verify_link_cap during detection.
[How]
Since preferred link settings are already considered inside
decide_link_settings, skip the check in override_training_settings
to avoid infinite link training loops.

[Why]
Trying to enable multiple displays simultaneously exposed shortcomings
with the algorithm for dynamic link encoder assignment.
The main problems were:
- Assuming stream order remained constant across states would
sometimes lead to invalid DIG encoder assignment.
- Incorrect logic for deciding whether or not a DIG could support a
stream would also sometimes lead to invalid DIG encoder assignment.
- Changes in encoder assignment were wholesale while updating of the
pipe backend is incremental. This would lead to the hardware state
not matching the software state even with valid encoder assignments.
[How]
The following changes fix the identified problems.
- Use stream pointer rather than stream index to track streams across
states.
- Fix DIG compatibility check by examining the link signal type
rather than the stream signal type.
- Modify assignment algorithm to make incremental updates so software
and hardware states remain coherent.
Additionally:
- Add assertions and an encoder assignment validation
function link_enc_cfg_validate() to detect potential problems with
encoder assignment closer to their root cause.
- Reduce the frequency with which the assignment algorithm is
executed. It should not be necessary for fast state validation.

[Why]
Current FPU code for DCN2x is located under dml/dcn2x.
This is not aligned with DC's general source tree
structure.
[How]
Move FPU code for DCN2x to dml/dcn20.

[Why]
Overriding link setting inside override_training_settings
result in fallback link settings being ignored. This can
potentially cause link training to always fail and consequently
result in an infinite loop of link training to occur in
dp_verify_link_cap during detection.
[How]
Since preferred link settings are already considered inside
decide_link_settings, skip the check in override_training_settings
to avoid infinite link training loops.

In current code, when a PCI error state pci_channel_io_normal is detectd,
it will report PCI_ERS_RESULT_CAN_RECOVER status to PCI driver, and PCI
driver will continue the execution of PCI resume callback report_resume by
pci_walk_bridge, and the callback will go into amdgpu_pci_resume
finally, where write lock is releasd unconditionally without acquiring
such lock first. In this case, a deadlock will happen when other threads
start to acquire the read lock.
To fix this, add a member in amdgpu_device strucutre to cache
pci_channel_state, and only continue the execution in amdgpu_pci_resume
when it's pci_channel_io_frozen.

In the rare event when GFX IP suspend coincides with a s0ix entry, don't
schedule a delayed work, instead signal PMFW immediately to allow GFXOFF

Allow us to query instances versions more cleanly.
Instancing support is not consistent unfortunately. SDMA is a
good example. Sienna cichlid has 4 total SDMA instances, each
enumerated separately (HWIDs 42, 43, 68, 69). Arcturus has 8
total SDMA instances, but they are enumerated as multiple
instances of the same HWIDs (4x HWID 42, 4x HWID 43). UMC
is another example. On most chips there are multiple
instances with the same HWID. This allows us to support both
forms.
