Mountain Lion: Native Ivy Bridge CPU and GPU Power Management

UPDATE - 6/28/13 - Added ML CPU Native Power Management System Definition Recommendations

UPDATE - 2/11/13 - Includes PikeRAlpha's IB SSDT Generation Script
(ssdtPRGen.sh)

CPU Native Power Management System Definition Recommendations

0. Previous generation processors (i.e., Core2...)
0a. use native ssdt.
0b. SysDef: macpro3,1
1. !st Generation Core i processors Nehalem/Westmere (i.e., Core i7-875K)
1a. use native ssdt
1b. SysDefs: imac11,x, macbookpro6,x, macpro5,1 (2)
2. 2nd Generation Core i processors/Sandy Bridge (i.e., Core i7-2600K)
2a. use MultiBeast/Customization/SSDT Options/Sandy Bridge (4)
2b. SysDefs: imac12,x, macmini5,x, mabookpro8,x
3. 3nd Generation Core i processors/Ivy Bridge (i.e., Core i7-3770K) (3) (5)
3a. processor specific ssdt required, see SSDT generation script (Ivybridge PM) (4)
3b. SysDefs: imac13,x, macmini6,x, mabookpro9/10,x
4. 4nd Generation Core i processors/Haswell (i.e., Core i7-4770K) (3) (5)
4a. processor specific ssdt required, see SSDT generation script (Ivybridge PM) (4)
4b. SysDefs: imac14,x, macbookairi6,x, mabookpro11,x

Notes
():
1. CPU PM applies to the installed processor (not relevant: motherboard series, OS X version, graphics, etc.)
2. macpro5,1: remove S/L/E/AppleTyMCEDriver.kext to avoid KP on restart
3. Using one of these sysdefs without a custom ssdt disables CPU PM
4. SSDT generation script (Ivybridge PM) supports 2nd, 3rd and 4th generation Core i processors.
5. If Ivy Bridge ssdt not installed, use Sandy Bridge ssdt and sysdef.
Code:
[B]Processor/OS X version[/B]       
[B]Gen[/B][B]    10.6    10.7   10.8   10.9
[/B][B]Prev[/B].   All     All    All    All
[B]1st[/B]     All     All    All    All
[B]2nd[/B]    .6.8     All    All    All
[B]3rd[/B]            .7.5    All    All
[B]4th[/B]​                   .8.5    All
Summary
1. Ivy Bridge power management requires 10.8.2 or newer, edited SSDT, edited AppleGraphicsPowerManagement.kext and Ivy Bridge System Definitions: macmini6, imac13, macbookpro9/10 (Note: 10.8.2 Supplemental/Supplemental 2.0 Updates are not working)
2. 3rd Gen/HD4000 processors without Ivy Bridge power management should use Sandy Bridge sysdefs: macmini5, imac12, macbookpro8 (Note: Sandy Bridge Power Management is working; ignore Console/WARNING: IOPlatformPluginUtil : getCPUIDInfo: this is an unknown CPU model 0x3a)
3. 2nd Gen/HD3000 processors on a 7 Series motherboard should use Sandy Bridge Bridge sysdef. 4. macmini6 and macbookpro10 are working, imac13 is partially working. HD4000 is working with a kernel error.
5. This guide enables native power management, optimizing CPU and GPU power management is left to the experts.

Issues:
1. iMac CPU power management partially working
2. HD4000, 100% functional, kernel error

IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Mac-F65AE981FFA204ED.plist

In all OS X systems up to and including Sandy Bridge, native power management was enabled by ACPI_SMC_PlatformPlugin.kext, a plugin in IOPlatformPluginFamily.kext. For Ivy Bridge processors, native power management is enabled with the X86PlatformPlugin.kext.
HD3000 processors on a 7 Series motherboard should not use Ivy Bridge power management.

AppleGraphicsPowerManagement.kext/Contents/Info.plist

Like the X86PlatformPlugin.lext, the board-id is used for product specific graphics power management. IGPU (integrated) and GFX0 (discrete) are the dsdt device names for the standard Mac configurations (Note, the ML HDMI audio edits rename the native device names to IGPU and GFX0).
IGPU is only HD4000; HD3000 processors on a 7 Series motherboard should not use Ivy Bridge graphics power management. On the iMac and MacBookAir models, max power is half of MacBookPro. However, reducing max power does not reduce performance. A kernel error remains (AICPM failed to load ring table). The ring table is present in IOReg/X86PlatformPlugin.

For optional discrete graphics (iMac13), the discrete graphics card device_id is used for graphics power management. Ivy Bridge graphics power management is significantly easier to implement. For Macs without discrete graphics (Mini), simply adding the device_id power profile to the appropriate board-id adds graphics power management (i.e., Vendor10deDevice1086).

ML: Native Ivy Bridge Power Management

If your Ivy Bridge system already has native power management is there any advantage to going this route?

I no longer have the P8Z77-I build or I would test it on there.

If I extract a DSDT from the MSI Z77A-GD65 using NullCPU and booting from the backup ROM on the original BIOS, make these edits to the DSDT do I need the SSDT?

The Ivy Bridge advantage is lower power and slightly more performance. IB power management on IB processors delivers lower power. My 3770K idles at 1600 MHz with SB PM and idles at 1200 MHz with IB PM (can be set as low as 800 MHz). IB PM also manages the power on HD4000 graphics (13 steps from 700 MHz to 1300 MHz). SB PM does not support integrated graphics.

IB PM does not address the locked register in the AMI BIOS. Patching the AMI BIOS for OS X is still required, regardless of the processor generation. As well, the native SSDT does not support OS X power management for SB or IB and the SB SSDT is different than the IB SSDT.

OK, updated to 10.8.2 with a side step to delete a certain OEMSMBIOS kext.

I get this at boot: IMG_1177.JPG

but it seems to have little effect as I get this from MSRDumper: Console.jpg

In any case, here is a new ioreg

The boot messages are the difference between i5 (4 threads) and i7 processors (8threads), no worries. To fix, remove cpu4, cpu5, cpu6 and cpu7. I think there is big difference between 2 p states and 7 p states. You have confirmed IB PM is working on your system, without a dsdt.

Toleda, could you please help me...

When you say "use SandyBridge sysdefs", do you simply mean (in my case, where I have a 7 series MB with a 2nd gen i5-2450 processor) that I should use a MacBook Pro 8 for the smbios.plist file, or something more than that?

Also, when you say "ignore Console", what does that mean, please?

Hope you [or someone else] don't mind answering these questions for a newbie.[/

Summary/Item 3 represents your situation:
1. Use a Sandy Bridge sysdef: macmini5, imac12, macbookpro8
2. You will not see the console message with a Sandy Bridge processor using Sandy Bridge power management.

This isn't working yet but I am working on it, so to speak ... using the iMac13,1, as you noted, there are some issues. I have resolved one, I think, and maybe the info will spark other ideas. I am on a Dell 17R SE 3D, i7-3630QM and even at this juncture things are much better on start up using the iMac board ID.

i had to add a method call behind the cpu1 thru cpu7 SSDT entry points for the ACST method just like the call for APSS - when I did that, the CStates table in the IOREG is now filled out (it was empty under cpu1 thru cpu7 before). Less messages (all of the unexpected data for C1, etc. are now gone) but same result at the moment, still no ring table.

I did find my bug - when I updated your i7 table with my cpus values, I miskeyed one of the values so I had three values at the same level and it couldn't figure out which was the last normal pstate; fixed.
