samtimbaud, fyi you don't need speedstep on for xpcm to work properly.

Also that entire post has a lot of useful information... There's a list of entirely new kernel flags for xpcm besides just -xpcm:
-xcpm
-xcpm_assert (sets machdep.asserts to 1)
-xcpm_assert_trace (sets machdep.asserts_traced to 1)
-xcpm_ignore_fv (ignores the frequency vectors)
-xcpm_ipi
idlehalt
cstates
Also a ton of information can be found using sysctl.
By the way, has anyone tried Pike's AppleIntelInfoto to see if it shows more information than intel power gadget?
Here is the github: https://github.com/Piker-Alpha/AppleIntelInfo
You can build it yourself pretty easily.
download the zip on the right side, then unzip it and navigate the the folder:
build it:
navigate to the folder of the new kext:
set permissions and ownership:
and load the kext:
Then open Console.app, in the "All Messages" log search for aicpupmi.
You can also install it to /S/L/E if you wish, the difference is if you do that it will log to the console constantly.

We can now even disabled EIST, Turbo and the Cn states in the (UEFI) BIOS and XCPM will still work. A big change.
