2025-11-24drm/amd/pm: adjust the visibility of pp_table sysfs nodeYang Wang
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.

2025-05-08drm/amd/pm: Avoid open-coded use of ratelimit_state structure's internalsPaul E. McKenney
The amdgpu_set_thermal_throttling_logging() function directly accesses the ratelimit_state structure's ->missed field, which works, but which also makes it more difficult to change this field. Therefore, make use of the ratelimit_state_reset_interval() function instead of directly accessing the ->missed field. Nevertheless, open-coded use of ->burst and ->interval is still permitted, for example, for runtime sysfs adjustment of these fields.

If a device supports runtime pm, then pm_runtime_get_if_active returns 0 if a device is not active and 1 if already active. However, if a device doesn't support runtime pm, the API returns -EINVAL. A device not supporting runtime pm implies it's not affected by runtime pm and it's active. Hence no need to get() to increment usage count. Remove < 0 return value check. Also, ignore runpm state to determine active status. If the device is already in suspend state, disallow access.
