-xcpm flag ignored for ivybridge processor - cpu locked at lowest frequency

[esther]

So I just noticed that Sierra is ignoring the -xcpm boot flag (worked with 10.10 and 10.11) and uses AICPM for power management. Is this normal/expected behaviour?

Moreover my multiplier is locked at the lowest value (8x) and won't scale up. Could this be because I am using an ssdt generated with Pike's script using the -x flag?

gosh, I wish I didn't upgrade

Thanks.
I regenerated the ssdt with the latest script and now scaling seems to be working better. How can I check GPU frequency and available P-states? I used to do it with DPCI manager, but is not working with sierra.

(I still wish I hadn't upgraded :-/)
