Version 1.4.5 is out as a beta. Please test and report.
http://code.google.com/p/xnu-speedstep

• "Error getting PState array from ACPI" - if you get this error with older versions, this new version will try to create a pstate table for you based on some heuristics. It is not optimal, but will give you a headstart. Later you can fine-tune the pstate table yourself.
  
• Info.plist has a new key "TargetCPULoad" currently set to 30%. Change it to whatever you want to be the default.
  
• Should also fix the incorrect (high or -ve) cpu frequency problem.

The module failed to load on my machine. Confirmed the same behavior in both xnu-dev's most recent beta (2c) and Vanilla 9.5. Attached is the dump generated by the Vanilla kernel. Vitals in the sig. Thanks again for your great work on this project!

Hi Mercurysquad,

Has the memory Leak issue been fixed ?

Does this kext use ACPI_SMC_PlatformPlugin.kext to get the pstates ?

My system hangs during the installation   I install using terminal. After seemingly successful sudo copy of the file, the system just hangs ... and there's nothing I can do except hard reboot. Booting in single user mode then shows the file is not there  

Will update as it goes when I can install it!

Thanks for the release though. Great work.

[d!g!t@lTr@sh]

Finally installed (although still unsucessfully, using kext helper, machine still hangs after copying the kext). After repairing permissions in single mode, get a kernel panic.

Works fine for me here.

The earlier one did,so this one should also work.

I installed the IntelEnhancedSpeedStep.kext and it installed fine. How do I check to see if it is working and doing what it is suppose to do. I was thinking the speedstep.app would have some gui function when I try to run it...nothing pops up or nothing happens. Am I suppose to only install the kext or not run the app or do I install the kext and run the app. Any help will be appreciated. Thanks.


PS- I installed version 1.4.0 since many ppl here are reporting problems with 1.4.5.

If the kext is installed it is probably doing its job quietly in the background. You don't need to start any app.

To confirm, open Terminal and type:

sysctl -a | grep throttle

You should be able to see the current frequency and voltage, the list of available frequencies and voltages, the target cpu load, and whether auto throttle is active (kern.cputhrottle_auto: 1).

When I type in the sysctl -a | grep throttle in the terminal, I get the following error: "kern.exec: unknown type returned" Does this mean the kext did not install properly or do I have a non compatible kernel runnning? Thank for your help.

Hi,

Has the KP been fixed ?or was this issue with old kernel only(kernels older than 9.5) ?

The kext is compatible with all kernels. If you only get that line and don't get anything else then that means the kext is not working properly. In that case you should edit the kext's Info.plist file and set DebugMessages to true, then type sudo touch /System/Library/Extensions and reboot. After rebooting type sudo dmesg | grep Intel to see a list of debug messages. Paste those here.

Not yet, I got busy with the Voodoo kernel and other things .. once Voodoo is released I'll work on this.

Thanks man,no problems.

You've really inspired me to read "Mac OS X Internals By Amit Singh".I'll just grap a copy and start reading it.Chapter 10 would be of more interest to me coz of IOKit.
Anyways thanks for everything.

Will this work with a P-M ? i tried superhai but i gave me problems

Mercurysquad,
I was wondering that if I have a correct DSDT will I still get "Error getting Pstate array from ACPI" ?(Assuming i use version 1.4.4 of this kext)
