Quick Guide to Generate a SSDT for CPU Power Management

tonymacx86 · Nov 1, 2015

Piker Alpha's ssdtPRGen script will generate a SSDT you can use to achieve the maximum amount of power states for your desktop CPU. Please note that desktop power management is not mandatory.

Requirements:
Working internet connection

How to Generate a SSDT for Power Management

1. Configure system with appropriate SMBIOS for your CPU using Clover Configurator

2. Open Terminal and download Piker Alpha's ssdtPRGen.sh

Code:

curl -o ~/ssdtPRGen.sh https://raw.githubusercontent.com/Piker-Alpha/ssdtPRGen.sh/master/ssdtPRGen.sh

3. That will download ssdtPRGen.sh to your user directory. The next step is to change the file mode (+x) with:

Code:

chmod +x ~/ssdtPRGen.sh

4. For default SSDT generation, type:

Code:

sudo ~/ssdtPRGen.sh

5. Type n, n

6. Open Finder and in menubar choose Go/Go to Folder...

7. Type ~/Library/ssdtPRGen/

8. Mount EFI using EFI Mounter v3

9. Copy SSDT.aml to /Volumes/EFI/EFI/CLOVER/ACPI/patched/

NOTE: The Power Management SSDT should always be SSDT.aml. If you have an SSDT.aml there already, rename it SSDT-1.aml, etc...

10. Reboot

How to Test Power Management

1. Download and compile AppleIntelInfo.kext using XCode. Or download here: View attachment AppleIntelInfo.kext.zip.

2. Drag AppleIntelInfo.kext to desktop

3. Open Terminal

4. Type:

Code:

sudo -s

5. Type:

Code:

chown -R 0:0 ~/Desktop/AppleIntelInfo.kext

6. Type:

Code:

chmod -R 755 ~/Desktop/AppleIntelInfo.kext

7. Type:

Code:

kextload ~/Desktop/AppleIntelInfo.kext

8. Type:

Code:

cat /tmp/AppleIntelInfo.dat

The amount of power states will then show in the Terminal window.

Perfect, yesterday, I tried it by following the "old" guide, can anyone please check my result?

details (logs, terminal logs etc.) are in this post: http://www.tonymacx86.com/mavericks...cpu-igpu-power-management-86.html#post1142796

Output from kext

Code:

And I do not know, but I think that turbo mode wont start

How does the SSDT need to be referred to in the config.plist file?

zoona · Nov 5, 2015

I think...

Clover
1. Clover Configurator (1 or 2, not both)
  1. ACPI/Set DropOEM ((Ignore if 9 Series) or
  2. ACPI/Drop Tables
    1. SSDT/CpuPm
    2. SSDT/Cpu0Ist
  3. Save (Export)
  4. Example

Firs of all thanks
Second, what is the benefit?
Third I just generated ssdt.aml and ssdt-1.aml and put them in the patched folder with DSDT.
I got one error, it said Board-ID doesn't support ivy bridge but I generated anyway.
Here is the test result I hope I did correct.

The benefits are that the are more states, so if your desktop is idle it will be at 16 (1.6GHz) or when your rendering a video it will be at 37(3.7GHz) if you did not generate an SSDT it would be stuck at one state.

"Error: Unknown processor model" on my i5-6600k. I guess this hasn't been updated for Skylake yet?

I can't understand, i don't have any SSDT and i have at least 2 states (1,6 and 3,5 GHz)...
Is it possible ?
