New version 1.1 of GenericCPUPowerManagement, For Speedstep/Cool'n'Quiet and other power management Options

[Superhai]

This thread is becoming a bit unmanageble for me to follow, because there are so many different issues, and some of you are very poor at posting specs or outputs and following directions.

I suggest all of you with some kind of issue. Read the documentation. If you don't find an answer, make a new thread on my forum at http://www.superhai.com/ , describe it as detailed as possible. Ensure this has to do with CPU power management, or are caused by it. (I.e. no fan control, backlight, smbios, or whatever)

If it freezes, run the debug version of the kext in "single user mode" (only -s option at boot). Include in the post a picture of the screen when it freezes.

If it is not freezing you need to post me a bug report as it is stated in the documentation. You find a link to the documentation at the first post or on my website.

Failure to do the above, will either result in ignore and the issue considered solved or that your post is deleted.

And no PM's whatsoever.

What does this thing do?
It will control some aspects of power management for your cpu. Most important is the speedstep functionality, to lower power footprint. It makes your cpu cooler or your battery lasting longer.

Update on 20th of December 2008

1.1.4 Fixes for netburst (p4, pd, etc) and other bugfixes
Version 1.1.3 mainly bugfixes.
1.1.2: AMD PowerNow running as well as other bugfixes.
A few new features including T-States or stopclock throttling (intel only for now). Should give some more time out from the battery if not running resource heavy apps.
Now the GUI app is ready, and also the command line tool. Go to http://www.superhai.com/ to find downloads.

I have released version 1.1
This is a major rewrite and therefore a new app will be required for those of you who want to see the values. That is not ready yet so have patience. The kext loads and works fine by itself. I will try to create a pdf or similar so to have a better help for you to understand all features.

What is new in 1.1?

• AMD implementation
• New option to use ACPI Performance State Control
• Better automatic CPU detection and probing
• Much improved multi core support
• Source is easier for me to maintain and have fewer bugs
• A new GUI application
• A command line app
• Much more information provided

Yet to come

• Small fixes for Non Constant TSC CPUs
• Minimal footprint release with no external control
• New bugs etc.

Any ideas for improvements? Tell me

GenericCPUPowerManagement Help

-------------------------------------------------------------------------------------
Not working? Do this:
After the kext is loaded, post the output of this to me;

CODE

sudo dmesg | grep GenericCPUPowerManagement
ioreg -lxw0 -r -c GenericCPUPowerManagement | grep "Characteristics"
ioreg -lxw0 -r -c GenericCPUPowerManagement | grep "Status"

After request from a few, I also added shutdown/restart fix functionality, which works for some of you.

Download is here:
http://www.superhai.com/darwin.html

Support forum is here:
http://www.superhai.com/forum/viewforum.php?f=12
I would prefer if you post feedback there

You don't need to copy it to /System/Library/Extensions to run it if you don't want it at startup.
Just copy it somewhere and ensure that you do a

sudo -s
chmod -R 755 GenericCPUPowerManagement.kext
chown -R root:wheel GenericCPUPowerManagement.kext

then a

kextload GenericCPUPowerManagement.kext

To unload it again you can use

kextunload GenericCPUPowerManagement.kext

It will complain about "Kext has immediate dependencies on both com.apple.kernel and com.apple.kpi components; use only one style" because some functions are required from both kpi and kernel.

If you have frequency issues on intel cpus, check that your system is able to provide the correct FSB. This is not an issue of this kext, but your system. On AMD you should make a bug report.

The app can be anywhere, but in /Application is ok, no need to set any custom permission.

And last but least thanks to mercurysquad et al for some of the ideas and basis of this kext. This is free app and kext, but it is limited and reserved licence and not for any purpose or fitness. Commercial distribution is prohibited without additional licence.

[THe KiNG]

Thanks so much!
As always GREAT JOB!
Work as it should now on my T8300 CPU.
Still I want to go under 39*C (j/k)
Now if you don't mind I have some tips for the application:
- when info data is selected on menu bar to can chose what value to remain( for me only interested for all day long is temp. and freq., no need for the rest)
- freq to be integer not like now 832, 978 etc. (just cosmetic)
and app needs a icon

Thanks again!

Hi.
Thanks for you hard work and nice gui for the speedstep app...

Here is all the info i can get from my cpu (i tried to use cpuz under parallels, but it didnt gave me all the info and i dont know how to get it on my hackintosh... will try more programs to get all the info...

Yes, I know this, and yesterday evening i released an update to correct the load, (i forgot to divide by 10 so it showed 10 times higher!) I am trying to sort out with the cpu freqs, but i choose to do this by tables and intel have so many almost equal cpus

Hi, i loaded the newest .kext wirth success. (C2D 4400, EP35)
But the CPUMControl shows lock like below and it seems that no control is available.
Could you explain what the red text means ?
Must be something with my new board, i have now GA-EP35-DS3 and the ACPI of that.
Also the orig. 1.3.2 speedstep.kext didnt work anymore (using my old PSTATES).
EDIT: I have in idea: I also installed (to change board) some new kext for that board (pcwiz).
Maybe thats the problem.
I remember i has an loaded ACPIThermal.kext or similar named - now not.
And also remember that thats essential for some tools.
Must be a .kext of the ACPIPlatform i think.
I will report that later.

I added my old AppleACPIPlatform.kext content and the newer/changed one .
There are much less plugins in the newer one !
Can someone tell me which are needed . All of them run well with old MSI-965P i dont know why pcwiz didnt included them.
I wrote an pm to pcwiz also, he is always very helpfull.

It means, that the kext didnt load. Try the debug version and look at the output in dmesg or system.log. The correct ACPIPlatform kext has only 3 plugins. The other plugins are from old versions. But this kext does not depend on any plugins of acpiplatform.

Hey, it's working here (specs in signature), but the app shows 100-225 MHz. Kinda strange for a T8100! This is what I got with grep:

Here are some experiences by me. Voltage can be quite a bit lower (925). So far Multiplier change results in immediate crash. (everything under windows)

Great work so far! Thanks

a bit confusing is that the terminal says:

: GenericIntelCPUPowerManagement.kext loaded successfully

Which parts (.kexts) can be ACPI depended (SMSBIOS.kexts also ?!) ?

I also added IOREGISTRY output screensoout (CPU1 less ACPI entry, but that was ever i can think, also with the old board)
Also i remember i had always (3 diff boards 4 CPU entrys in ACPI, 2 with values (0-1, OK my C2D 2 Kernels, 2+3 not). No problems

EDIT: Even if kext is NOT loaded - try kextloading it makes CPU run at slowest PSTATE - not controlable - half results in geekbench.
Also HW Monitor shows that MHZ drop.

Tomorrow I will update with tables for the cpus that i have received now. Should fix your issue. It is nothing wroong that ACPI has 4 and IOCPU has 2. It is because of hyperthreading. It says succesfully loaded as the kext loads successfully. But it unloads because it is not able to get the p-states from acpi. It is possible you have issues with your appleacpiplatform.kext. Try to avoid to use moded versions of acpi, system and the superclass kexts.

Here are some experiences by me. Voltage can be quite a bit lower (925). So far Multiplier change results in immediate crash. (everything under windows)

I will add it in the table that voltage. Tomorrow should I have kext with updated cpu tables.

[BlackCH]

I tryed the app/kext. Looks very good; but I cannot get the 'most important' speeds (800 and 2000 mhz). With mercurysquad kext+old app I can get 800-1200-1600-2000 mhz. With your kext 1200-1400-1600-1800 mhz. I used to get 800-1200-1400-1600-1800-2000 with coolbook...
I will post the details of my cpu and debug logs...

great job superhai!, thanx!
