I have a T7300 too. When running with the kext and the app set to displaying freq I see it jump back and forth between 600 and 1000 quite a lot. For instans just by typing this message in safari it switches all the time. When I in a former version got 800-1200-1600-2000 it was very stable in 800 except when doing something heavy.

 

You can set the threshold for when it will switch the p-states in Info.plist in the kext.

Your kext works very well now for me, also detection of energy source (AC or battery) works with Chun Nan (Now named Eureka) ACPIBattery kext....!!!!!

 

Thanks, now my hack is almost complete... (Next step is sleep, perhaps with pc_efi 9 !)

I have chmoded it and all but when loaded

 

FavleX:~ ema$ sudo kextload /Users/ema/Desktop/superhai/GenericCPUPowerManagement.kext 
kextload: extension /Users/ema/Desktop/superhai/GenericCPUPowerManagement.kext is not authentic (check ownership and permissions; run with -t for details)

1. recursive owner/group needed : sudo chown -R root:wheel /Users/ema/Desktop/superhai/GenericCPUPowerManagement.kext

2. also do recursive : sudo chmod -R 755 /Users/ema/Desktop/superhai/GenericCPUPowerManagement.kext

This may needed after DL or if you change something in the .plist

Just did it before but no way ;)

[Edit] My fault.I'm dumb.Mistake on typing :P

 

Then , the kext is loaded correctly , the app is working but when using it on manual the cpu freq doesn't change at all

It is stuck at 798MHz.

Tried last version on Msi Wind

The Frequency cursor doesn't move on the GUI interface

You have a gigabyte board right?

 

Yes a DS4 and the Wind indeed.

 

Now I must remember how to change FSB as u mentioned before..

I overclocked my Q9550 to 3.4Ghz and the frequency is no longer recognized correctly:

 

Daxs-Apple-Mizuki:~ dax$ ioreg -lxw0 -r -c GenericCPUPowerManagement | grep "CPU "

"CPU Status" = {"Auto Throttle"=Yes,"Load"=0x0,"Temperature"=0x15,"Current profile"=0x0,"High jump"=0x12c,"Voltage"=0x3db,"Timer"=0xfa,"Low jump"=0x96,"Frequency"=0x96,"Kext Timer"=0xb56,"Kext Online"=Yes,"Current state"=0x3,"Voltage ID"=0x16,"Frequency ID"=0x6}

"CPU Init" = {"CTL max"=0x481d,"FSB frequency min"=0x64,"Signature"=0x1067a,"FSB frequency max"=0x64,"CTL min"=0x616,"Kext unlock"=No,"Kext version"=0x10010,"Brand string"="Intel® Core™2 Quad CPU Q9550 @ 2.83GHz","Voltage max"=0x433,"Frequency min"=0x96,"Frequency max"=0xd4,"Voltage min"=0x3db}

 

It shows up as:

Did I miss something basic? :lol:

 

Edit: Hmm, it seems like sysctl isn't recognizing my CPU speed very well. It also says 150mhz.

Likewise, looks like it's because the CPU is detected as having a minimum frequency greater than the maximum Here's the dmesg output when using the debug build:

Ok.It's supposed to be 800Mhz to 1600Mhz.

 

So In ur opinion what can I do for having it correctly recognised ?

 

I got it tested with vanilla and voodoo_beta2 kernels as well.

 

Just to say...

With modified dsdt, that kext and Apple's intelcpupm i've won one hour of battery !

 

What ? ;) could you be a bit more detailed please ? Very interested !

any way to add fan control to this too?

 

PS, I'm using a lenovo s10, it is an atom 270, my frequency shows 300-600, but it's a 1.6 ghz chip, probably the same issue the MSI wind poster had, same chip & chipset

 

 

Before loading kext, about this mac shows 1.6 ghz

 

after loading kext it shows 600mhz

 

 

and the control gui only lets me go up to 600 mhz

 

hw.busfrequency shows the same before and after loading the kext

and the control gui only lets me go up to 600 mhz

 

hw.busfrequency shows the same before and after loading the kext

 

Weird.IN my case ,tried on battery , the cpu and freq changed

No, that is out if this scope... unless you have a fan inside your cpu :)

You have wrong fsb as well. The Atom CPU should show around 533 MHz. Fix that.

 

GenericCPUPowerManagement: [Debug] CPU bus frequency is 533 MHz

Chip in the MSI Wind is the Intel Atom N270, normal speedstep range is 900MHz to 1600MHz (ignoring overclock settings). Let me know if you need any extra info. :)

 

If you had correct fsb reported from OSX it would have showed 133 MHz not 533. Tell me if you use pc_efi, what smbios etc.

 

Mh it's working now, but it still displays the wrong frequency. I also get a KP when the voltage is too far down. I don't think it happens on auto mode, but I tried manual mode on 925 mV and the computer crashed.

 

Post the output of ioreg -lxw0 -r -c GenericCPUPowerManagement | grep "CPU "

If you undervolt with high frequencies the cpu becomes unstable. Therefore you get a kp.
