ML: Native Ivy Bridge CPU and GPU Power Management

[ktzyeah]

hi,
i'm using imac13,1 model on i7 3770 and z77-ds3h with clover 1750 (uefi). I got this with ssdtprgen script:

sdtPRGen.sh v6.1 Copyright (c) 2013 by Pike R. Alpha
----------------------------------------------------------------
Processor Declaration(s) Found in DSDT (ACPI 1.0 compliant)
Generating ssdt_pr.dsl for a iMac13,2 [Mac-942B59F58194171B]
Ivy Bridge Core i7-3770 processor [0x0704] setup
With a maximum TDP of 77 Watt, as specified by Intel
Number logical CPU's: 8 (Core Frequency: 3400 MHz)
Number of Turbo States: 5 (3500-3900 MHz)

Injected C-States for CPU0 (C1,C3,C6)
Injected C-States for CPU1 (C1,C2,C3)

the problem is that with msrdumper i see that i'm only getting 2 p-states (16 and 39)
am I doing something wrong? i tried to change smbios model to macmini6,2 and 6,1, imac12,2 and 13,2 but it's always the same.

Post to SSDT generation script (Ivybridge PM) . Attach dsdt, ssdt and a copy of IOReg. [Guide] How to Make a Copy of IOReg.

Suggest AppleIntelCPUPowerManagementInfo.kext (MSRDumper successor)

I'll do it thanks.
Btw Speedstep is working fine with Chameleon 2235 and Macmini6,2!

it's only not working with Clover 1750... and with Macmini6,2 the system reboots itself during boot...

Verify ssdt is in the right place and config.plist is configured properly. Clover is off topic.

Hello
I need some help, I can not run just GFX0 with macmini smbios (HD4000 disabling in the bios) or GFX0 as primary.

Everything works perfect with GFX0 as secondary or only with HD4000

Graphics Radeom HD6870
CPU i5 3570k
Board Z77 Pro4-M

is there any way to use macmini smbios without IGPU?

with iMac smbios works perfectly.

attempt to modify AppleGraphicsPowerManagement.kext not work

Hi toleda,

I also need some help, thank you in advance!
before I created the ssdt, speedstep seemed to work fine (system definition was macpro3,1) but sleep didn't.

So I went trough your guide, changed system definition to macmini3,2 (because it works best if I got that correct?), created the ssdt and put it into extra. boots fine but now speedstep only shows two states and sleep still doesn't quite work (all fans stay on, only screen goes black.. I hoped to resolve that by getting power managment to work.. is that even correct?)

attached are dsdt, ssdt and ioreg.. :/

ssdt gen looks like this:

What BIOS graphics setting? Are you using GE=Y? What mod did you try that did not work with AGPM?

 

[toleda]

any advice?

The edited ssdt,aml is not loading; likely it is named wrong and in the wrong place. For Chimera, rename ssdt_pr.aml to SSDT.aml and install /Extra.

Allright, I renamed the ssdt to SSDT.aml and put it into /Extra, rebootet and now MSRDumper
only switches between 8 and 16
ôO

it used to be 16-42 without the ssdt.
Sleep still not working :/
is it the mac mini definition?

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).
