Info plist Pstates doesnt goes to 800mhz #1

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Enter manually values in the Plist to undervolting 
2. reload the kext (reboot)
3. the throttle does not go to 800 mhz

What is the expected output? What do you see instead?
spected to go to 800 mhz, but stays in 1200 as the lowest freq

What version of the product are you using? On what operating system?
1.3.2 on 10.5.4 (vanilla kernel)

Please provide any additional information below.
I can get 800 Mhz wheen the kext gets the pstates by itself. I was tempting
to override the defaults by putting different voltages on the Plist. Using
C2D T7250 (2,0 ghz). Defaults:

kern.cputhrottle_freqs: 800 1200 1600 2000 
kern.cputhrottle_factoryvolts: 876 988 1148 1292 

the rest of the values (freq, voltage) on the plist works fine, just the
lowest pstate gets ignored desregarding what voltage I use for it.

Could you edit Info.plist again, and change DebugMessages to <true/>, then 
reload the kext and try going to 
800 MHz again.

Then please type:
echo `sysctl uname -a && sysctl hw.busfrequency && sysctl machdep.cpu && sudo 
dmesg` > ~/Desktop/Log.txt

And attach the file from your desktop and post here.

Before nothing i want to say thank you for this great work!
Im having exactly the same problem with the same t7250 intel processor, Log.txt 
attached!, im having this 
problem when i try to enter pstates manually on info.plist, i want to do it 
manually because the acpi doesnt give 
the pstates and the heuristic are giving undervolt (940v) and overvolt (1292v) 
while the specs says that it works 
on 1075v-1175v and maybe it is causing my notebook shutdown on high load.. 
Im using v1.4.0 because on v1.4.9 auto throttling is not working anymore for 
me..
Again, thanks and sorry for my bad english!
