ML: Native Ivy Bridge CPU and GPU Power Management

Kazbah · Jul 27, 2015

Trying to enable Ivy bridge CPU Power managment on my build to no avail so far ..

I generate the SSDT with PikerAlpha's script .. i5-3570K no overclock with a sysDef of iMac13,2

@Boot the firmware confirms that it found and injected SSDT.aml
but it still don't see X86PlatformPlugin in IOregistry

Any idea ?

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,

Code:

if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

You'll need to do the appropriate research to determine how Ozmosis deals with SSDTs.

I'm not familiar with it.

According to the bootlog, only SSDT.aml is being injected. SSDT-1.aml has your ssdtPRgen.sh output.

I don't see patchmatic output (no RehabMan directory).

Kazbah · Jul 27, 2015

The whole zip file is the Rehabman directory into which I copied output from IOReg..

SSDT.aml genrated from the script was copied where Ozmosis needs it ... I do not know if there is anything to do with the other files generated by the script .. I've looked at the script and if this be Clover would only copy SSDT.aml to the /Extra folder

The script content is in SSDT-1.aml. According to your bootlog, Ozmosis is not loading it. I don't know if you have an additional SSDT that is SSDT.aml (maybe an OEM SSDT?)?

That's between you and Ozmosis. I have no experience iwth Ozmosis and plans to look into it.

Your DSDT also has a bunch of stuff that duplicates SSDT-1.aml content.

This poses a problem for the content in SSDT-1.aml as the entire SSDT will likely be ignored by OS X.

A good way to detect that there are serious issues with the ACPI config is to attempt disassembly:

Code:

If you can't disassemble the injected files as a group (iasl -da), then you're likely to have issues with OS X as well.

This is becoming interesting ...

I placed a file called SSDT.aml in /Efi/Oz/Acpi/Load. Oz finds it and injects it but when we extract it with patchmatic it comes out as SSDT-1.aml ...

From what i have seen so far , OZ doesn't care what the file is named as long as it end with .aml.

If i would remove my own SSDT, reboot and run patchmatic -extract I guess we would get whatever is provided by the firmware, right ?

Your system is obviously loading an OEM SSDT, which becomes SSDT.aml "in front of" SSDT-1.aml.

If i would remove my own SSDT, reboot and run patchmatic -extract I guess we would get whatever is provided by the firmware, right ?

As I already detailed for you, your problem is in the DSDT you or Ozmosis is providing. No possibility to make the generated SSDT work with that DSDT.

Kazbah · Jul 28, 2015

I am not providing a DSDT so whatever is there comes from the firmware...

I will do some more research/digging (actually research where i can research this some more) on how Oz works ...

Thanks for your time it is very appreciated
