Does your native CPU power management work?

[VioletDragon]

To check out CPUPM only

ioreg -c X86PlatformPlugin | grep CPUPStates

if it is working you will see something similar to

| | |   |   "CPUPStates" = ({"Frequency"=3600,"PState"=0},
{"Frequency"=3500,"PState"=1},{"Frequency"=3400,"PState"=2},
{"Frequency"=3300,"PState"=3},{"Frequency"=3200,"PState"=4},
{"Frequency"=3100,"PState"=5},{"Frequency"=3000,"PState"=6},
...

Need to verify that AppleLPC is loaded. You can check in ioreg or Kernel Cache.

I get no response to "ioreg -c X86PlatformPlugin | grep CPUPStates"

So does that mean I have no powermanagement?

Probably because AppleLPC isn't loaded. Attach ioreg can soon tell you. [Guide] How to Make a Copy of IOReg | tonymacx86.com

Attached is my ioreg

Please explain how to read it!

Well you have more of a problem but AppleLPC is loaded but X86PlatformPlugin isn't loaded but AGPM Controller which indicates to me that using Mac Pro 5,1 is causing a issue with Powermanagement change to iMac 14,2.

I had to much audio popping on iMac 14,2
All those went away wit Mac Pro 5,1 def

But I guess also my powermanagement went down the drain...
Is switching back the only option?

Of course. No Mac Pro has ever had Z87 chipset with a i7 4770k. Audio popping can be caused by AppleHDA not patched correctly. Maybe not having Native Powermanagement implemented can also cause it might require a IRQ patch.

Switched back to 14,2

here is the new ioreg

Where do I need to look for difference?

 

[TomHsiung]

Ioreg shows that X86PlatformPlugin is loaded along with AGPMController. AppleLPC is also loaded. Only thing is that SATA is coming under SAT0 should be under SATA in ioreg.

Despite so, the Intel Power Gadget showed no CPU speedstep.

At least, my issue is that the Intel Power Gadget shows a constant CPU frequency (nearly a straight line) all the time (during idle).

Looks like your CPU is working with native power management. Power gadget hasn't been updated for Sierra maybe that is why it shows garbage for your system. You can use hardware monitor with fakesmc plugins if you don't believe me.
