SSDT generation script (Ivybridge PM)

[PikeRAlpha]

Hi Guys need help to understand a little. I used the script and got (first pic) what happens when I execute by entering password?

That allows ssdtPRGen to download IASL (the Intel compiler/decompiler) and place it in: /usr/local/bin/

It already created the ssdt_pr.dsl but when opening with dsdt editor i get second pic. I delete last line and get it to compile, but I don't think it's right. What do u think?
Thanks for the help.

There is no need, or there should not be a need, to modify the generated SSDT, or the whole purpose of ssdtPrGen would be pointless. Anyway. If you want to have a look at the generated DSL file, that can be done with almost anything. Even TextEdit, but it's like RehabMan said; Use MacIASL

OK so then I will let it complete through then...It makes sense. So after its done, just put in extra folder and select ssdt drop in boot plist and give a go?

thanks Pike and Rehabman...

Pike ran like a charm. Great work on this! MacIasl worked very well, compiled with no errors. I do now see another step @x22 in HWMonitor. Is there a test or software I can run to see how many more speed steps it added if any?

Yes there is. In fact there are different kind of soups for this, but since I like to promote our work... here it is:

Also. Here is something that you –– and the others here may want to try:

Set the top multiplier in your UEFI settings to 45. This will help to speed up the boot/shutdown process. Then run ssdtPRGen from a terminal window with something like (example):

ssdtPRGen.sh 4500 77 1

After this you change the value of Name (APSN, 0x04) to 0x1C. A side effect of this is that it will change the aggressiveness of the power management kext.

You can experiment with this value to get what you like it, but don't set it past the 16 multiplier. Mine is set even higher, but that is because I changed the top multiplier to 50. And using a higher value of ASPN will stop it from triggering the highest multipliers all the time.

p.s. You should get more p-states with this trick

As I suspected only 3 p-states on my laptop. Unfortunately I cannot set multiplier in bios to try your tip. Have a look at my ssdt,should I have more steps? Its a i3 3110M cpu.

Processors without turbo support generally have less p-states, and you should use AICPUPMI: to get the data we want. In particular the: "Low Frequency Mode" which may be lower than what ssdtPRGen assumes is right.

How do I get the lower frequency? What changes in the ssdt file do I need to do if any to get that. Sorry Pike but kind newbie at this.

See link in past #324 – report the data we need there.

p.s. Warning. I don't have a lot of time right now so I can be a tad slow from time to time!

when i run ssdtPRGen.app this is what the terminal window is showing:

But i've overclocked my CPU (3770 non k) to 4100mhz so i run the following
~/Download/ssdtPRGen.sh 77 4100

the terminal window doesnt return anything and my geekbench scores are really low. Is there something i need to do after running ssdtPRGen.sh 77 4100?

You should invert order values like ~/Download/ssdtPRGen.sh 4100 77
