There could be configs where some UMC instances are harvested. This
information is obtained through discovery data and populated in
umc.active_mask. Avoid reassigning this as AID mask, instead use the
mask directly while iterating through umc instances. This is to avoid
accesses to harvested UMC instances.

Now that we can select a workload profile dynamically when
we submit work, it's best to default to the bootup
default workload profile. Defaulting to other profiles
prevents some power management features from kicking in
during idle periods. Once all jobs have finished, the
workload profile will automatically move back to default
bootup for max power savings.

Add helpers to switch the workload profile dynamically when
commands are submitted. This allows us to switch to
the FULLSCREEN3D or COMPUTE profile when work is submitted.
Add a delayed work handler to delay switching out of the
selected profile if additional work comes in. This works
the same as the VIDEO profile for VCN. This lets dynamically
enable workload profiles on the fly and then move back
to the default when there is no work.

Current kfd driver has its own PASID value for a kfd process and uses it to
locate vm at interrupt handler or mapping between kfd process and vm. That
design is not working when a physical gpu device has multiple spatial
partitions, ex: adev in CPX mode. This patch has kfd driver use same pasid
values that graphic driver generated which is per vm per pasid.
These pasid values are passed to fw/hardware. We do not need change interrupt
handler though more pasid values are used. Also, pasid values at log are
replaced by user process pid; pasid values are not exposed to user. Users see
their process pids that have meaning in user space.

It is possible for some waves in a workgroup to finish their save
sequence before the group leader has had time to capture the workgroup
barrier state. When this happens, having those waves exit do impact the
barrier state. As a consequence, the state captured by the group leader
is invalid, and is eventually incorrectly restored.
This patch proposes to have all waves in a workgroup wait for each other
at the end of their save sequence (just before calling s_endpgm_saved).

The destructor of a gtt bo is declared as
void amdgpu_amdkfd_free_gtt_mem(struct amdgpu_device *adev, void **mem_obj);
Which takes void** as the second parameter.
GCC allows passing void* to the function because void* can be implicitly
casted to any other types, so it can pass compiling.
However, passing this void* parameter into the function's
execution process(which expects void** and dereferencing void**)
will result in errors.

Currently, there are several files in drm/amd/display that aim to have a
higher -Wframe-larger-than value to avoid instances of that warning with
a lower value from the user's configuration. However, with the way that
it is currently implemented, it does not respect the user's request via
CONFIG_FRAME_WARN for a higher stack frame limit, which can cause pain
when new instances of the warning appear and break the build due to
CONFIG_WERROR.
Adjust the logic to switch from a hard coded -Wframe-larger-than value
to only using the value as a minimum clamp and deferring to the
requested value from CONFIG_FRAME_WARN if it is higher.

hpo_stream_to_link_encoder_mapping has size MAX_HPO_DP2_ENCODERS(=4),
but location can have size up to 6. As a result, it is necessary to
check location against MAX_HPO_DP2_ENCODERS.
Similiarly, disp_cfg_stream_location can be used as an array index which
should be 0..5, so the ASSERT's conditions should be less without equal.
