Didn't realize 16-bits will max out so fast. For THM_GFX -
"SMU_THROTTLER_TEMP_GPU_BIT" looks appropriate. SOC domain will need a new one.
As temp throttling reasons are more, you may shift the "OTHERS" by 8-bits if
required.
Thanks,
Lijo

Great, thanks for all the feedback Lijo. Out of the new bit definitions in
amdgpu_smu.h are there any that currently exist that are more applicable for
these mappings? *_THM_GFX and *_THM_SOC only exist in VanGogh and Renoir. With
the expansion of the MEM and LIQUID bits there is not enough room in the
temperature field to add two new definitions.
Best,
Graham

Above two mappings don't look correct. They essentially mean throttling due to
GFX/SOC domain temperatures in APU exceeding their limits, not the VR
temperatures. Except those mappings, rest of the patch series looks good to me.
Thanks,
