Like I mentioned in the cover letter of this series, the CPPC patch is only compile tested. I'm trying to verify it at runtime, but I've put it out there early so that anyone who already has platform support for CPPC can help us immensely in giving it a try. Come to think of it, I should have probably mentioned this again in the subject of this patch. Will do it in the next revision. :)
I have some questions.
1. When os request the changing frequent to firmware, can the request be changed? (for example. if os request P0 state, can firmware change P0 into P2, p3 considering thermal or other condition)?
2. Can firmware change the P-state itself without OS’s request? -If it is possible, I think that cpufreq governor also should be changed. -And can firmware nofity OS the change then?
Thanks
Best Regards.
