Hi.

I have a question regarding this kext for speedstep : GenericIntelCPUPowerManagement.kext

If i load it using the instructions and then launch GenericIntelCPUPMControl. I can see by monitoring voltage and frequency that my CPU does Throttle even if i don't have Auto Throttle selected. Does this mean that my Bios takes care of it and i don't need to have the kext loaded or is it the kext that enables it? E.g. I only need to load the kext etc if i want to control manually or adjust the auto throttle in the app?

 

BTW seems to work ok for me, frequenzy readings are as correct as they can be etc Q6600..

OK, here is a screen shot and the logs from the new version. See for yourself that the frequency issue still exist, now it's even funnier than before (~3000MHz is the lowest 250MHz the highest)!

the combination of kext from here

LINK

with speedstep.app is working if i define the pstates manually in plist.

 

Yeah I have real problems with this laptop. ACPI-related

 

linux

no speedstep at all, no display after wake from sleep, no usb 2.0

 

windows

speedstep only with RMclock, no S3 available at all, usb 2.0 only with vendors super old intel chipset driver

 

osx

speedstep working with IntelEnhancedSpeedStep.kext v1.3.2 (with manual plist edit), no display after wake from sleep, but machine responds to ping over network, no usb 2.0, hardrive spinning down and up every few seconds

no sound

 

so, as you can see big problems :(

 

is your kext manually editable for unrecognized p-states?

the 1.0.3 version can set my CPU at 2000 mhz (before only 1800), but still can not go to 800 mhz (1200 as lowest).

 

Im on a C2D T7250. Thats the ioreg output:

I am getting throttling however reaction seems to be a bit slow (2 seconds?) with threshold/intervals set at minimum.

4036 with Auto Throttling (minimal threshold and interval) and 4052 set at full speed.

 

Frequency bar graph never hits max.

 

Unfortunately I am not getting results with ioreg -lw0 | grep PerformanceStateArray

 

Hope this helps

"Unfortunately I am not getting results with ioreg -lw0 | grep PerformanceStateArray"

SAME FOR ME - i think thats because you/i have some ACPI (BIOS) Problems , so PSTATES can read from OS X, only direct (CPU).

Superhai uses for us an direct way (not over OS X device Tree) to get those values. It doenst matter really.

See my signature as reference,

how do i get those value in mac? i need cpuz?

ioreg -lw0 | grep PerformanceStateArray

 

not result for this, why?

 

p.s. the program works fine for me.

Nothing done, just loaded kext, then the app and set interval to 100ms.

 

Throttling works perfectly i think, no issues seen yet: 798Mhz, 950mV, 0%, 62 C with Safari and Geekbench opened. When Geekbench begins to test all values go up immediately!

 

 

Great work MegaHai! :(

 

 

PS: Does it AutoThrottle without the app loaded?

Bad news. Loading the kext from the command line just freezes the system. Loading the kext at boot time causes a kernel panic.

 

The original mercurysquad 1.3.2 kext appears to work OK using sysctl to change frequency although I see no difference in CPU temperature even after reducing down to 600MHz/748mV from 1700MHz/1484mV.

 

The system is a Dell Precision M60 with 1.7GHz Pentium M running 10.5.4 from a retail install with about 6 kexts changed/removed. The kernel is mercurysquad's 9.4 & most everything is working although at present waking from sleep the screen stays black although the system is OK & I can use ssh or VNC to connect to it.

Well it's not for Mac's. Hack's maybe, but killed my Macbook Pro. Had to kill it via command line in the install disk, cause it wouldn't stop killing the startup. In verbose mode it hung too after the "this data might be bogus" message. Can you make a mac version too?

 

Edit: Could it be because I am running 10.5.5? Not 10.5.4 or older too? Just a thought.

Works good here...

 

It finds 4 P-States (Before i have to manualy sets it, mecury's kext finds only 2 pStates...)

 

Really good work... But i continue to use old 1.4 kext, because it more smooth with... (window animations, movies...)

 

Can we manualy undervolt our proc ?? Like 1.4 old kext ... Is the only thing i regret...with smoothing !

I can't try our test.

 

My hack freeze here : kextload GenericIntelCPUPowerManagement.kext

 

and i can report you this :

"PerformanceStateArray" = (<40060000c05701000a0000000a0000002808000028080000>)

 

CPU Type [Core 2 Duo E4500]

CPU Signature [?] Mobile CPU [NO] Latency [?] us

Max multiplier [11] Half multiplier [6] TjMAX [55] C

Control Max [8*366=2928] Min [6*366=2196]

Range: Frequency [2928] MHz to [1200] MHz, Voltage [Default] mV to [Default] mV

Voltage stepping [Default] mV.

CPU Family [6] Model [F] Stepping [D] revision [M0]

 

If it could helpme to have the speedstep...

 

PS : i've only windows on my parallels emultor, not natively.

I found out: most E C2D have more than one version(Core stepping) with different tMax.

CPU Type [__________E4400 (2.0 GHZ@2.33)________________________________________]

so changes for my E4400 Stepping L2 , 6f2, C1E=12 Watt (CPU Sig is the key for getting your Stepping, Sig 6fd = M0 (newer, LESS C1E=8 Watt)

CPU Signature [6f2] Mobile CPU [No] Latency [_____] us

Max multiplier [10] Half multiplier [No] TjMAX [_61.4 (L2) insted of 73.3(M0)____] C

You can find that TjMAX, Core Stepping(=Version), Watts:

I have tried a couple of other kernels (ToH 9.2, StageXNU 9.4) but with both I get a kernel panic when loading this kext. Is this a generic SSE2 problem or just my particular system (Dell Precision M60, Pentium M 1.7GHz, 10.5.4 retail install). Mercurysquad's 1.3.2 kext works OK so it is some problem with this particular kext.

Just so you know, I am on vacation and will not work much on this before end of september/beginning of october.

 

Anyway, if you have panic, I NEED what kind of panic you have.

I.e. the text on this line: panic (cpu X caller 0xXXXXXXXX): <<panic text>>)

If you cant get it try to run the kext from single user mode (-s option from darwin boot loader)

and if possible also the text output from the kext just before it paniced (use the debug version)

Also kext version (it says on line after "Kernel loadable modules in backtrace...")

 

For the moment it will work best with core2 cpus as it is what i have tested it on, and which is able to autodetect pstates. If you have pentium m/celeron m/pentium 4/pentium D, i need the full cpu information if it is not working.

 

I have not added any features for checking for kernel and below 1000MHz states problems yet.

 

When I get back I will make some app to try to gather and test values more.

 

 

 

{censored} stole my idea. ideas arent safe on IRC ;)

 

Haha. It cant be, there is no pron in here. If you stopped w to the glossy donkey pictures under your fathers bed, you had time to do this :)
