ML: Native Ivy Bridge CPU and GPU Power Management

[RehabMan]

Yea i see it to but i don't have nullcpupowermanagement.kext installed, so i have no idea where it's coming from.

See post #742 (first two sentences of my reply)...

Thank you for pointing me in the right direction, found the nullcpu kext in another kext. Deleted it and now get instant panic instead. But now maybe i atleast can troubleshoot and get it to work.

You probably need patched AppleIntelCPUPowerManagment.kext.

BTW, what "other kext" did you find it in?

I tried to setup a good CPU and GPU PM guided
by this an other threads.
I got good CPU PM using ssdtPRgen like i already
explained in my own thread

Now i hang at the GPU Power Mangement with
my GTX 560TI
I copied the setting from FC02E91DDD3FA6A4 to my MacMini 6,2 definition (F65AE981FFA204ED)
and edited the GPU-ID:

I already mentionend in my thread, that my GPU works very smooth
in Desktop mode, but the perfomance in benchmarks seems very bad!
Also Open CL wasn´t enabled from the beginning!
It seems like my GPU get stuck at Idle mode a 50 MHz!
So how can i get proper AGPM + fully working GPU performance?

Thanks for helping!

See Post#1/AGPM, example: GTX 570.

Okay i carefully read your starting post again and again!
I kept my settings and tried to edit it with your screenshots!

After that, i got a working GTX 560TI at 850 MHz and benchmarks
are okay!
So my GFX seems to be working normal!


But now my GFX keeps always 850 MHz.
So AGPM doesn´t work yet!

The problem is Luxmark; try other apps.

Okay my benchmarks at Unique heaven are also good, but maybe
you haven´t understood my problem. (;
Now GPU stays at 850 MHz clock speed also in idle mode. It would
be nice, if my GPU would reach a lower level like before at 50 MHz.
What´s wrong again?

Just a quick question Toleda, is the SSDT transferable if down the line I decide to update to Maverick or does it need to be generated again? Thanks in advance

CPU PM does not change with system updates assuming the sysdef does not change. GPU PM does not change either, though, kext edits are required after each update.
