drm/amd/pm/smu13: BACO is supported when it's in BACO state

2023-01-10T23:10:34+00:00

This leverages the logic in smu11. No need to talk to SMU to
check BACO enablement as it's in BACO state already.

drm/amd/pm: correct the fan speed retrieving in PWM for some SMU13 asics

2022-12-20T18:22:56+00:00

For SMU 13.0.0 and 13.0.7, the output from PMFW is in percent. Driver
need to convert that into correct PMW(255) based.

drm/amd/pm: avoid large variable on kernel stack

2022-12-20T17:59:34+00:00

The activity_monitor_external[] array is too big to fit on the
kernel stack, resulting in this warning with clang:

drivers/gpu/drm/amd/amdgpu/../pm/swsmu/smu13/smu_v13_0_7_ppt.c:1438:12: error: stack frame size (1040) exceeds limit (1024) in 'smu_v13_0_7_get_power_profile_mode' [-Werror,-Wframe-larger-than]

Use dynamic allocation instead. It should also be possible to
have single element here instead of the array, but this seems
easier.

v2: fix up argument to sizeof() (Alex)
