Here is an example output with xrt-smi(1) tool.
# xrt-smi examine -r all | grep Power

Do you have a preference on how this gets merged ? Should it go
through drm-next or platform-x86-next?
I suppose whoever is going to have more development layering on top
the next cycle it would be preferable to put in that tree.
I do not have preference. :) And this depends on Shyam's previous patch
which is not in drm-next yet?
Thanks,
Lizhi
