Quick Guide to Generate a SSDT for CPU Power Management

Thanks, it's beginning to come clear to me. The double up of states simply means that it monitored twice.

No idea what you mean by "double up of states".
The kext writes a new line to the log whenever the set of observed states changes.

CPU-S is much the same with both SSDT in patched and without. At first blush it looks like p states are ok without any patches, which would be very nice.

Complete/correct PM only possible with "plugin-type"=1 injection.

So now I get 7 P states :)

You will likely observe more pstates the longer you monitor with AppleIntelInfo.kext.
 
Hello Guys,

I installed the SSDT generated by Piker-Alpha's ssdtPRGen.sh script V15.6
the CPU clock speed goes up and down as expected but sleep still wouldn't work
View media item 189351
So I tweaked my Clover settings using the configurator, added the EHC1 to EH01 and EHC2 to EH02 patches, compiled my DSDT, and now it sleeps (led off, fans off) and wakes perfectly, which is great! (not sure if DSDT or patches helped or not, anyway...) But clock speed stays around 3,4 Ghz.
View media item 189350
Not too much of a big deal, but I'm more into understanding the why than actually caring about what it does.

After reading a lot and testing countless options, I no longer use the ssdt.aml (now generated by ssdtPRGen.sh v21.5 - IDK if it makes a difference with the one generated with V15.6), since I read that on Haswell, CPU PM is handled by XPM. So I used RehabMan's SSDT-PluginType1.aml - and I got IOClass, String, X86PlatformPlugin activated, sleep works, but no low power states.

So I'm clueless, can you help me figure it out?
I attached everything that may be relevant, plus the -v boot without SSDT
Thanks in advance.

Did you build the kext from source?

hello

I'm running OS X Sierra 10.12.6 and I used ssdtPRGen.sh to try and generate ssdt but ge this

System information: Mac OS X 10.12.6 (16G29)

Brandstring: "Genuine Intel(R) CPU @ 2.00GHz"


Error: Unknown processor model ...

Visit http://ark.intel.com to gather the required data:

Processor Number

TDP

Low Frequency Mode (use AppleIntelInfo.kext)

Base Frequency

Done.

then I try ssdtPRGen.sh -p 'E5-2683 v3’ -turbo 2300 and get this



Error: Invalid argument detected: -p E5-2683 v3’ -turbo 2300 /Users/admin/Downloads/ssdtPRGen-4.sh-Beta/ssdtPRGen.sh -p E5-2683 (check ssdtPRGen.sh -h)

Aborting ...

Done.

any help??
 
hi!
I have followed the instructions and I had to use the beta branch to generate de file (i7 6700k)
When the script is running I got the following text:
Code: 
[B]Warning[/B]: 'cpu-type' may be set improperly (0x0705 instead of 0x0905)

    - Clover users should read https://clover-wiki.zetam.org/Configuration/CPU#cpu_type

[B]Error[/B]: board-id [Mac-27ADBB7B4CEE8E61] not supported by Skylake – check SMBIOS data / use the -target option


Do you want to continue (y/n)? y

if I continue I get the the next message:

Code: 
Warning: 'system-type' may be set improperly (1 instead of 2)
	 - Clover users should read https://clover-wiki.zetam.org/Configuration/ACPI#acpi_smartups
Compiling: ssdt_pr.dsl

but it is ok to use it?

It is telling you that your hardware does not match the iMac14,2 system definition.
Consider changing to something more suitable.
