VoodooPower 1.2.3

[vali29]

Yes, but how do I solve this so that my CPU would stay cool and quiet fan runs ±2600rpm cpu temp - 50 degrees. What do you use? Or maybe you just put up with the noise?

 

I've installed this version http://www.insanelymac.com/forum/index.php...898&st=150# but the system it's running very slow.

Only when i run more program's the frequency of processor it's going up.

I can not adjust the frequency from GenericCPUPMControl. They stay at 1000Mhz.

 

 

 

Sorry for my bad english.

AMD K8 (only) VoodoPower.kext (1.2.3 + patch) + mach_kernel (voodoo 9.5.0 + patch)

 

Sorry for the bogus version last time.

Try this one ( at your own risk ) if you need power management and less timing change on K8 platform.

 

http://www.mediafire.com/?ytl5yjdzngb

 

In case you want to set p-state at max, just "pstate 0".

(It is necessary if you play sound with USBAudio and might be necessary to play music/movie )

 

I include source files for the case you need to debug / tweak.

If it does not work, please build your own kernel/kext or just avoid using it.

 

Note: old MB which has no ACPI_PSS support would not load the kext.

Thanks hnak! This one works flawlessly, no problems at all. Happy to have a quiet system! Temp. is about 40 degrees.

Thanks for this hnak, you're the boss!

 

This is gonna help superhai to broaden his scope with VDPW

I would like to implement this in my kernel but I need to know if there are any disadvantages for other cpu's by patching the kernel this way...

If there are I'll make a boot argument for switching this on...

Great work BTW

Hi

No problem so far with Hnak´s kext on a gigabyte ga-ma78gm-s2h, Phenom 9550 2,2 Ghz. Pstate shows 1100mhz on idle, 2200mhz when converting videos, watching HD movies.

Only "problem" is that i have to run a terminal command to view my temp..

 

Thanks Superhai and Hnak for your good work on AMD support

Hi Andy,

It is great if you incorporate the changes into your new kernel.

The patch is safe. I believe it should be enabled by default. It basically does the same thing as what the original voodoo does in less dangerous way.

 

CPU with constant TSC never calls the modified entries anyway. Systems without PowerNow/SpeedStep kext never call it. Actually, the Apple's original implementation is ospanic.

 

Here is the diff.

Run this python script if you care about pstate/freq/volt/temp. ( assuming pstate exists in path, for example /usr/local/bin/ )

You might have to install xcode ( not sure). If you install xcode, you can also build an executable applet.

Sorry to bother you once more but could you make an unified diff rather than a regular one with diff -Nur?

It is easier to apply to newer sources...

Thanks in advance

You use both GenericCPUPowerManagement and VoodooPower?

Remove GenericCPUPowerManagement.kext + Extensions cache...

hnak, I'm testing your latest kext and it's running great so far, the only thing is that the temperature seems odd, it's higher when it's running at the lowest frequency. Any idea?

How do you monitor the temperature ?

If you are using pstate, it reads CPU thermal sensor, but pre-revision 0FH processor (I believe you are using rev.E) does not have the sensor. ( at least, it is not formally supported .)

My kext just reads the thermal register and returns the value regardless of CPU revision.

Hey Hnak, Thanks again for the fixed. So; I've installed the AMD K8 (only) VoodoPower.kext (1.2.3 + patch) + mach_kernel (voodoo 9.5.0 + patch) on my AMD Turion Tl-64 . The only problem I've having right now is when I adjust the pstate to either 3,2,1,0 my fan starts to run constantly. But when I have it on 4 (the fan is somewhat quiet) or on auto the fan can auto throttle by itself (and adjust to how heavy I''m using the system). I don't want to burn out my fan (by always putting it on pstate 0 )but I also want to watch movie and I don't want to manually adjust the pstate to 0 everytime i want to watch a movie and change it back to auto in order to get good sound (without the jittering). So my final question is, is there anyway to get my fan quiet or autothrottle (or at least make my fan quiet down) when I set pstate to 0 in order to watch movies or any type of media without the jittering audio? I've tried to delete all the cputhermal.kext intelcpumanagement.kext and thermalcpu.kext but it doesn't see to work.

No way.

Fan is tied to MB hardware and we have no control on it. (At least, you need to write a driver for you own hardware )

Fan must work at pstate 0 to avoid burning CPU anyway.

As audio jittering is caused by TSC change, you need to fix it at some state in case of non constant TSC processor.

Hey Hnak, thanks for giving me the clue of TSC change; so now I'm booting with cpus=1 (although I'm only running with one cpu but the sound is definitly much better) and idlehalt=0 and I'm able to go on auththrottle without any audio jittering. I hope this helps other people.

I think idlehalt=0 helps at the cost of power consumption. K8 stops counting TSC in halt state.

Does your Turion have 2 cores ? If so, cous=1 is also useful as no TSC synchronization is necessary. Maybe I should check whether TSC difference is big enough before executing TSC sync, because when idlehalt=0, TSC difference between cores should be much smaller.

Yes, I do have two cores. When I boot with cpus=2 and idlehalt=0 (I have the MCP67 chipset and I need to do this in order to boot faster or else it'll take me 30+ minutes just to boot) I get the jittering sound. But with cpus=1 and idlehalt=0 no sound jittering but only one core; :\, maybe you can look into being able to use both cores with no sound jittering.

If you can build kext from Superhai's project + my source, please try disabling TSC synchronization (code block to check and call AMDTSCSync()) in VoodooPower::processorDriver() and build, install, then boot with idlehalt=0.

I would love to build the kext for you; but I have no idea how to edit any of the parameters you just mentioned above or how to build a kext in general. If you can do a step by step tutorial I can follow it or else; I would have to ask you to build the kext with those settings and I can definitely test it for you to see if it works or not. Thanks again.

OK, I try to explain step by step.

 

1. Install xcode from OSX DVD. Or you can register yourself as a developer at http://connect.apple.com and download it. - it's big.

 

2. Once you install xcode, go to Superhai's website and follow the link to get the original project files. In short, execute the following command in terminal.

svn checkout http://voodoo-power.googlecode.com/svn/trunk/ voodoo-power

 

3. Open the xcode project file in the folder named "VoodooPower" in the folder above. Use the popup menus on top-left to switch to "Release" build. Then choose "build" from menu. The kext will be built in [Project folder]/build/Release/. Note: This is the original VoodooPower.

 

4. Replace VoodooPower.cpp of the project with my AMD version (included in zip) and do "build" again. You get the AMD version. This is the kext you are using.

 

5. locate the next 2 parts and remove ( or comment out ) them, then you can build what I said!

	// Properly update kernel frequencies when no constant tsc
if (k8_data.syncTSC && GlobalRequest[0].fid != fid0) {
	uint64_t tsc = rdtsc64();
	IOSimpleLockLock(SimpleLock);
	mp_rendezvous_no_intrs(AMDTSCWrite, &tsc);
	IOSimpleLockUnlock(SimpleLock);
}

 

	// Properly update kernel frequencies when no constant tsc
if (k8_data.syncTSC && GlobalCurrent[0].fid != fid0) {
	uint64_t tsc = rdtsc64();
	IOSimpleLockLock(SimpleLock);
	mp_rendezvous_no_intrs(AMDTSCWrite, &tsc);
	IOSimpleLockUnlock(SimpleLock);
}

Okay Hnak, I did what you said and I tested out the new Kext also; there are some bad results. running on idlehalt=0 cpus=2; when I load my computer the pstate is at 0; even when it's on authrottle the pstate stays at 0. If I manually change the pstate to 4 I still get the jittering sound.

Thanks for testing.

Humm... it is different from my result with Athlon X2 4050e. I can see pstate changes at least.

Does pstate stay at 0 even with only finder ?

 

By the way, I found that TSC difference between cores stay within less than 500 without my crude synchronization code. Voodoo Kernel engineers must have done some smart job.

 

Will you try this one ?

This is what I am working on ( to support both Intel and AMD )

This is the continuation of GenericCPUPowerManagement under a new name.

thx so much superhai! this totally fixed my overheating issues with my amilo li 2727

[clipt81]

Hallo!

first of all, I'd like to thank you for all the work you've done.

I've always used your speedstep (new and old), but I've always meet

a recognition error of the cpu...

my processor is an 2,4 but he think that's an 2,21 one.

if I do a control with a xbech he say me that the score is less.

you can find my hardware down (in my signature), could you help me, please?

I await for your reply and

 

i thank you.

bye
