Only V13.0.2 on SMU v13 will get 0 based max level from fw and
increment by one, other ASIC will not need for this.
V2: replace the asic_type check with ip versioning check.

Some initial settings now are not available from
the atom data table. The assumption that !ps[0]
|| !ps[1] in amdgpu_atom_asic_init is not valid.
In addition, driver needs to strictly follow
atomfirmware structure (asic_init_parameters) to
initialize parameters used to execute asic_init
function, otherwise, the execution of asic_init
would fail.

While technically Xen dom0 is a virtual machine too, it does have
access to most of the hardware so it doesn't need to be considered a
"passthrough". Commit b818a5d37454 ("drm/amdgpu/gmc: use PCI BARs for
APUs in passthrough") changed how FB is accessed based on passthrough
mode. This breaks amdgpu in Xen dom0 with message like this:
[drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3
While the reason for this failure is unclear, the passthrough mode is
not really necessary in Xen dom0 anyway. So, to unbreak booting affected
kernels, disable passthrough mode in this case.

*** DEADLOCK ***
This commit fixes the deadlock warning by ensuring pm.mutex is not
held while holding the topology lock. For this, kfd_local_mem_info
is moved into the KFD dev struct and filled during device init.
This cached value can then be used instead of querying the value
again and again.

The logic to update the IO links when a KFD device
is removed was not correct as it would miss updating
the proximity domain values for some nodes where the
node_from and node_to both were greater values than the
proximity domain value of the KFD device being removed
from topology.

All uses of the 'kfd->gtt_sa_bitmap' bitmap are protected with the
'kfd->gtt_sa_lock' mutex.
So:
- prefer the non-atomic '__set_bit()' function
- use the non-atomic 'bitmap_[set|clear]()' functions instead of
equivalent 'for' loops. These functions can work on several bits at a
time

'kfd->gtt_sa_bitmap' is a bitmap. So use 'bitmap_zalloc()' to simplify
code, improve the semantic and avoid some open-coded arithmetic in
allocator arguments.
Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.

From [1], I realized two other calls to dcn30 code are associated with
FPU operations and are not protected by DC_FP_* macros:
* dcn30_populate_dml_writeback_from_context()
* dcn30_set_mcif_arb_params()
So, since FPU-associated code is not fully isolated in dcn30, and
dcn3.1.x reuses them, let's wrap their calls properly.
Note: this patch complements the fix from [1].

There are two error code bugs here. The copy_to/from_user() functions
return the number of bytes remaining (a positive number). We should
return -EFAULT if the copy fails.
Second if we fail because "context.resp_status" is non-zero then return
-EINVAL instead of zero.

suspend, and eventually s0ix entry will be blocked.
