SSDT generation script (Ivybridge PM)

[giacomoleopardo]

I've tried to get Power Management working on my rig, but I get a kernel panic. I have a simple rig: GA-Z77X-UD5H, i5-3570K, HD 4000, no external GFX. I have generated a smbios.plist with Chameleon Wizard, using the iMac13,1 system definition. I've ran the sdtPRGen.sh script, loaded the generated SSDT_PR.dsl in DSDT Editor, saved ssdt.aml in /Extra folder and added DropSSDT=Yes to org.chameleon.Boot.plist. Toleda stated in the thread http://www.tonymacx86.com/mountain-...tive-ivy-bridge-cpu-gpu-power-management.html that installing the 10.8.2 Supplemental Updates breaks Power Management. Is that also the case for the sdtPRGen.sh script?

I've updated my system (macmini 6,2) and IvyBridge PM works, post #96

I've updated my system (macmini 6,2) and IvyBridge PM works, post #96

I have changed my system to macmini6,2, generated a new SSDT_PR.dsl:

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

and generated a new ssdt.aml, but still get the kernel panic, see attached photo.

Edit: Toleda has just updated his instructions in http://www.tonymacx86.com/mountain-...tive-ivy-bridge-cpu-gpu-power-management.html. I followed his instructions using the pre-edited ssdt_pr_3570k_4200oc.aml. Now it's working. I used the macmini6,2 definition. Thanks all, great work!

Hi all,
I get this output:

sdtPRGen.sh v3.3 Copyright (c) 2013 by Pike R. Alpha

Ivy Bridge Core i5-3317U processor installed
./ssdtPRGen.sh: line 1212: let: logicalCPUs=: syntax error: operand expected (error token is "=")

The processor (i5-3317U) is detected correctly, what's wrong?

The processor (i5-3317U) is detected correctly, what's wrong?

Thank you for spotting this error – we missed a zero in the cpu data array. All should be fine in version 3.4

Interesting. This is the first time I see that error (not the KP). The output is fine, for a vanilla (non-OC'ed) setup so is your computer OC'ed or not?

@Francis,

First. Thank you for testing this. And what you have in object SPSS is normal (see biosbits.org) but I was hoping that the extra P-State in object _PSS made it tick for Apple setups, since that is basically one extra frequency. Your testing however revealed that this didn't work. At least not for you. Which is too bad, but what I don't understand is that, looking at the disassembled code of the kexts, why it reads both APSS and _PSS without jumping over the read of _PSS when it finds APSS.

I also think that using 15 P-States in a _PSS object, combined with a _CST object, without having APSN/APLF works. In that case CPUMaxNonTurboPState gets set to 1 by the kext. Which is exactly right. Maybe Apple did this to support older (think MacPro) setups... who knows.​

No, my computer is not overclocked.

Hmm. I don't understand why you need the extra P-States, especially since none of them will be used. Please attach the output of sysctl -a so that we can start digging for clues.

I've tried the script again:

After the warning the script stops, but the file SSDT_PR.dsl is generated and placed on the desktop. I generated SSDT.aml with DSDT Editor, put it in /Extra and rebooted. It works. It seems the only issue now is the warning, but it has no effect on the result apparently. Maybe I did something wrong the first times I tried the script, I don't know. Here is the output of sysctl -a:
