[Guide] - SSDT with Pike's PM Script and use with CPUFriend

[onemanosx]

Update: Creating injector kext with CPUFriend script 

 

What is CPUFriend?

Step A. Creating SSDT Using Pike's Script

 

1. Go to Pike’s Github and download ZIP master https://github.com/Piker-Alpha/ssdtPRGen.sh

 

 

2. Extract “ssdtPRGen.” folder and copy and paste to /Users/YourUsername/Library

4. Download attached “Data” folder and replace existing Data folder in “/ssdtPRGen”

Data.zip

 

5. Open “User Defined.cfg” file in “ssdtPRGen/Data” folder

6. Open Coffee Lake.cfg file and look for your processor type ( in this example, I will be using “i5-8600”)

7. Paste your CPU details in User Defined.cfg and save file

 

 

Note: If you plan to use a different clock speed frequency (mostly for energy saving) or base/turbo frequency, here is where you make the desired frequency changes. The example in the screenshot above is setting using clock speed of 500 instead of OEM 800.

 

8. Open Terminal

9. Type

cd ~/Library/ssdtPRGen/

 

Hit Enter

 

10. Type CPU format as such (for i5-8600) :

 

./ssdtPRGen.sh -p 'i5-8600' -f 3100 -turbo 4300

 

11. Press Enter

12. Let the script run and when script asks Do you want to open ssdt.dsl (y/n)? Just return N.

 

 

13. Your ssdt.aml and ssdt.dsl can be found in ~/Library/ssdtPRgen folder

 

Step B: Generating SSDT data using CPUFriend script

 

1. Download CPUFriend master zip https://github.com/acidanthera/CPUFriend

While you’re there, download CPUFriend kext from the release tab and place the kext in Clover/Kext/Other

 

2. Extract CPUFriend-master folder to desktop

3. Open terminal

4. Type

cd ~/Desktop/CPUFriend-master/Tools

 

Hit Enter

 

5. Type

./ResourceConverter.sh --acpi 

 

 

Then drag ssdt.aml from ~/Library/ssdtPRgen folder into terminal window and press ENTER

 

6. Your ssdt-data.dsl result can be found at ~/Desktop/CPUFriend-master/Tools folder

 

Step ? Combining CPUFriend data into Pike's SSDT

 

1. Open the ssdt-data.dsl and copy the whole scope of “cf-frequency-data”

 

 

2. Go to ~/Library/ssdtPRgen folder and open the file ssdt.aml

3. Find the _DSM section

4. Paste “cf-frequency-data’ like shown in the screenshot. Also, delete 0x02 in the Return line leaving just the brackets or else your will not be able to compile.

 

 

5. You can save the ssdt.aml and copy to Clover/acpi/patched.

 

Reboot and enjoy!

 

Note: If you do not find the cf-frequency-data as shown like in the IOReg screenshot below, it means the SSDT is not injecting properly. You might want to consider creating CPUFriendDataProvider kext instead.

Some of us might prefer to use injector kext instead of SSDT. This is how its done.

 

Creating injector kext with CPUFriend script

 

1. Type

./ResourceConverter.sh --kext

 

 

2. Drag ssdt.aml from ~/Library/ssdtPRgen folder to terminal and Press Enter

3. Your CPUFriendDataProvider.kext will be generated and can be found at ~/Desktop/CPUFriend-master/Tools folder

4. Place both CPUFriendDataProvider.kext and CPUFriend.kext in clover/kext/others

 

 

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

 

 

Unknown CPU

 

What if I have a CPU that is unknown and not in the .cfg list? Can I still generate ssdt using Pike's script?

 

Yes. And this is what we have to do.

 

1. Determine CPU details by going through https://ark.intel.com and fill in the details for an i5-8600 as an example.

 

Code Name: Coffee Lake
Processor Number: i5-8600
Max TDP: 65
Low Frequency Mode: 3100
Clock Speed: 800
Max Turbo Frequency: 4300
No. of Cores: 6
No. of Threads: 6

 

 

The format to be input in Coffee Lake. cfg and User Defined.cfg will look like this

 

i5-8600,65,800,3100,4300,6,6

Ok Thanks

[brynts]

what should I do if no _DSM in my ssdt.aml?

[onemanosx]

[ref]brynts[/ref], never experienced that in all of my 4 hack machines.

[MaLd0n]

[ref]brynts[/ref], if u don't like .aml/.dsl, generate a kext injector instead

Did you do step 7 from the guide?

 

[platinumsteel]

I followed the Guide exactly as I saw it my friend...

[onemanosx]

Good. You can hit the Enter/Return key at Terminal, if you have not done so
