SSDT generation script (Ivybridge PM)

[xpamamadeus]

Just find this, and try to make it work so I can use Macmini6,2 instead of MacPro3,1. I have a i5-3570K on H77ITX-A-E.

Few issue:
During generate ssh, I got two warnings:

~/ssdtPRGen.sh i5-3570K

After I apply new generated ssdt, I got:
MSRDumper PStatesReached: 16 21 28 34 36 37 38

I saw many people are get more than this, and lowest go to 12. What I did wrong?

Model: Macmini6,2
GeneratePStates=Yes
GenerateCStates=Yes
DropSSDT=Yes


Any idea?

Thanks

The next step is to make sure that SSDT's are dropped by the boot loader, and that it won't generate P/C-States for you because you don't need them with the generated SSDT.

I thought that we answered this a few pages back, no?

Someone else brought up the same question but with a similar CPU. Not sure if he made is own SSDT manually. There is no automatic way to create a SSDT with an Arrandale CPU?

 

[Noodle]

Thank you, but after I change both GenerateCStates and GeneratePStates to "No", it's still just MSRDumper PStatesReached: 16 21 28 34 36 37 38.

I'm sorry but there is no 1200 MHz support for your processor. You can check this yourself by using my AppleIntelCPUPowerManagementInfo.kext (use search) and that may as well show at least one more P-State.

@GostRaiderMX,

I'm afraid not.

@GostRaiderMX,

I'm afraid not.

How did you get the values for Sandy Bridge and Ivy Bridge processors for your script? I mean that shouldn't be different for Arrandale. Maybe I can use this information and make my own SSDT manually?

I think that Sam used biosbits.org but we changed the algorithm later on to match that of Apple. Which is slightly different.

At the risk of being regarded a complete fool, I have a question about ssdtPRGen:

I downloaded and unzipped ssdtPRGen.app and placed it on my desktop.
Double-clicked it and it created ssdtPRGen.command on my desktop.
Double-clicked it again and it opened a command/shell/terminal window. It shows:

I already found out that the two warnings are probably of no importance.
It downloads IASL after entering password
The app does create a ssdt_pr.dsl file on my desktop.
But i dont get a ASL or AML file; it says: permission denied.

On an other tutorial on an other site i read that I had to do this in my homefolder.
So I did that and now I have the same three files in my home folder as wel:
ssdtPRGen.app ssdtPRGen.command ssdtPRGen.sh

Well, I tried all the above a few times, including redownloading the original zip and extracting it.

Does anybody know a link to a tutorial how to use the ssdtPRGen app version 6.6?
Or better, tell me what I am doing wrong?

You are the first person to report this, but maybe we should change line 2121 and add sudo like this:

[FONT=Menlo]_   [COLOR=#D12F1B]"$iasl"[/COLOR] $gSsdtPR
[/FONT]+   sudo [COLOR=#D12F1B]"$iasl"[/COLOR] $gSsdtPR

Does that work for you?

 

[zetje01]

Thank you for your quick answer!
Maybe it has to do with that I login with user admin (and not a user with admin rights)

i will edit this message when i found out where to change your suggested lines, and do a follow-up.

EDIT:

Found it, changed it, ran it and:

So I guess it worked!
Thanks, Mr. PikeRAlpha!

(now on the next mission: ssdt_pr.aml is on my desktop, find out what to do with that )

If you're using Chimera or Chameleon bootloader, in /Extra you'll find ssdt_pr.aml. Just rename it as ssdt.aml, install AppleIntelCPUPowerManagementInfo.kext, reboot and check speed steps as stated in that thread from Pike
