I'm curious if you intend to bring back support for EAS with
intel_pstate in active mode down the line?
That would get this working out of the box across distros, since
`intel_pstate=active` is the default setup everywhere (and typically
what users should prefer? as I understand from the documentation.)
Thanks for your work!
