ML: Native Ivy Bridge CPU and GPU Power Management

[moonrotation]

hi Toleda, thanks for answering

I've tried bios settings PCI first whit multimonitor disabled, and onboard first. Only works with onboard first (I need PCI only)

My Graphics works OBB, also probe G=Y and G=N with the same result

and AGPM attempt to insert GFX 13,2 Imac (Mac-FC02E91DDD3FA6A4) in macmini 6,2

I'm using Clover UEFI

Agree, Only works with onboard first
If you are using imac13,2 GFX0 on your 6870, stop and remove. imac13,2 GFX0 is for Nvidia 6xx only.

Solved editing AGPM

Put "Vendor1002Device6720" from iMac on "Mac-F65AE981FFA204ED and replace 6720 with 6738

kernel[0]: [AGPM Controller] build GPUDict by Vendor1002Device6738
kernel[0]: AMDBartsGraphicsAccelerator: ** Device in slot: SLOT--1 **

but now not detect HD4000 (No problem)

for editing dsdt now is IGPU?

 

[toleda]

for editing dsdt now is IGPU?

Yes.

After power off pc, not working.

I can do? rename PEGP to iGPU on DSDT?

Edit:

Rename GFX0 to IGPU not work

 

[toleda]

Rename GFX0 to IGPU not work

No. See [Easy Guide] ML: UEFI HDMI Audio

No. See [Easy Guide] ML: UEFI HDMI Audio

thanks for your help, I think I'm giving up
I can not run with single HD6870, I think I have some conflict with bios, Ethernet does not work with MacMini and HD6870 (I have no idea) and my bios was broken after many tests and restarts. (AICPM stopped working, boot without DSDT worked but with HD4000 but with screen artifacts) All fixed after reflash bios

Using iMac everything works perfect, but I lose pstates and Erp messange on boot
next time buy motherboard recommended by the community

Not helpful. The only way to figure out what you really did is with a new IOReg. Ask a question, attach an IOReg, automatic.

Use AppleIntelCPUPowerManagementInfo.kext (MSRDumper successor).

new IOreg attached, sorry, I wasn't aware that I needed to reextract it every time.
just to sum up again:
put SSDT in place, set DropSSDT to Yes in org.chameleon.Boot.plist
now speedstep is between 8-16 while it was 16-42 without the ssdt.
I want a working ssdt though to get sleep to work properly (still the question whether I am on the right track here at all )

thank you!

Every time you make a change, IOReg changes.
What boot flags are you using?

What boot flags are you using?

here are my bootflags.
in general, I only set GraphicsEnabler=No
