v1:
- make pp_table invisible on VF mode (only valid on BM)
- make pp_table invisible on Mi* chips (Not supported)
- make pp_table invisible if scpm feature is enabled.
v2:
move pp_table invisible code logic into amdgpu_dpm_get_pp_table() function.
v3:
add table buffer pointer check both on powerplay & swsmu.

drm/amd/pm: Remove power2_average node2025-11-12T02:54:17+00:00Asad Kamalasad.kamal@amd.com2025-11-06T16:56:32+00:00urn:sha1:9dc8d07ce08364b53bab48271beda9c3fc7c085b
SOC power consumption is reported by power1_average.
power2_cap_default/min/max only represent second level limits
and don't represent a different type of power or power consumption
by a subsection of the SOC. Therefore power2_average does not serve any
purpose and hence removing power2_average sysfs node

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-redundant explicit call to
pm_runtime_mark_last_busy().

drm/amd/pm: Grant interface access after full init2025-10-13T18:14:35+00:00Lijo Lazarlijo.lazar@amd.com2025-10-08T07:37:13+00:00urn:sha1:2b5b3f9b698f8e5d6492763947231e7d9420d8da
Allow access to user interfaces like sysfs/hwmon only after full
initialization of the device. When device is part of XGMI hive and a
reset is required during initialization, the inteface files will be
created as part of minimal device initialization. Full initialization of
the device will be done only after all devices in XGMI hive are probed
and a reset is done together on all.

When passed around internally the upper 8 bits of power limit include
the limit type. This is non-obvious without digging into the nuances
of each function. Instead pass the limit type as an argument to all
applicable layers.
