Hi Paulicat
I tried the command sysctl -a | grep curfreq and sysctl -a | grep throttle

all gave me error message saying

"kern.exec: unknown type returned"

Is there anything I haven't done to enable this two command?

That means that CPUThrottle was not loaded correctly. If it did, you would get something.

Thanks Ppan76, then how can I load it?
But as I remember ACPIcputhrottle.kext is conflicting with 10.4.8 kernel right?

ok guys, this: "kern.exec: unknown type returned" is an error returned by ALL osx boxes. Its not from or related to my kernel mods.

Once Okik and I get our changes together, we'll have a solid kext.

Thanks Paulicat!, hope OKik and you can solve it

Ppan76, may be you are right
I try to kextload ACPICPUthrottle and it says

kextload: extension ACPICPUThrottle.kext appears to be valid
kextload: kmod_control/start failed for com.OSx86Project.kext.ACPICPUThrottle; destroying kmod

excellent ... so its only a matter of time now (hopefully).

Good work guys.

Thats the error i was getting, try loading it again, i.e: do it three times in one go. Or try the kext from my pkg

Thanks Okik
here is my system log after I tried few mor times

It's possible your BIOS does not think your system should be throttled and therefore did not return any available power states, or maybe your CPU only supports one other power state than maximum which is below 1Ghz!



I actually use your kext,
The CPU throttle doesn't work either, report frequency of zero and all option are blank

just for your reference.
my CPU is pentium D 945 dual core at 3.4G support EIST S3 T1M and in windows with CPU right mark utiliy I can set 7 VIP/PID from 12X (2.4G) to 17x (3.4G)
so I don't quite understand why it says my CPU doesn't support power state or max lower than 1G



btw
one more thing I found is that after install your pkg, I cannot try paulicat's pkg again.
Ppan76 seems able to do it, I wondering how? (go to back up kernel, delete /Library/Startupitems and delete the cpu throttle from application folder?)

The way I do is start macosx on single user mode (-s).
Then delete the CPUThrottle Kext from the \Library\StartupItems and copy my mach_kernel back.
After that you can install whatever packages you need as many times as you want to test.

I just realized there was a CPU Throttler Application Installed. I just launched it and tried changing the settings. Nothing happends when I change the CPU Speed or load or save a profile. Nothing happends.

Also when the appication is open. I cannot run Activity Monitor, Terminal and checking System Profiler don't return all the parameters.

Thanks.

Hello,

I've been testing all the flavours of this patch and I've been unable to get through the login window. I get a coreservicesd crash (the login windows does not apperar and the screen remains blue).
I tested it on a Vaio SZ1M laptop, 1.6 Dual Core Intel CPU.

Right now I'm stuck with the latest Paulicat Patch as I tried to boot the mach_kernel.bak but I get a kernel Panic as soons as it tries to load the CPUthrottler startup item.

Tried to boot with -s (single mode) but the filesystem is mounted as read only, does anybody know how to remove the StartupItems in single mode?

I'll reinstall the system and try again to see if the coreservicesd crash is due to another kext incompatibility.

I've managed to make everything working on this laptop (except wireless, dual nvidia/intel support and SpeedStep/Sleep) so drop me a line for help if you have a Vaio.

thanks for your work.

Simple fix for anyone testing.
Boot in -s mode
fsck -fy
mount -uw /
rm -fr /Library/StartupItems/ACPICPUThrottle

Reboot.

Remember guys, my kernel mod is the only one supporting speedstep, the only thing Okik and I have to work together on is the kext. I didnt write the kext, it was written Neall Douglas a while ago, probably before c2d's existed...
My kernel will act the same as any other kernel without that folder.

The kernel's the same for me, I was worried I may lose sound but it's good. I had to use Kikos Okiks kext because the latest paulicat wouldn't install. I still have no sleep, but I do have speed step working. I don't know if I like it. My bus speed is cut down to 100MHz and my CPU stays at 1.33GHz. It may sound odd but my temps seem to have gone up instead of down, by about 10C. I haven't tested battery life but I guess it would be longer, being that the clock speed is lower. I was hoping for a dual core fix, unfortunately still cpus=1. I can boot with both cores but system will freeze with in a couple minutes.

In my case the problem should be another issue because deleting the throttle StartupItem and booting from the speedstep modified kernel just does the same, a coreservicesd crash.

"Historically" I have always booted safely from any other kernel, 8.8.1, sf9 and DaemonES

launchd: Server 5a0f in bootstrap 1103 uid 0: "/System/Library/CoreServices/coreservicesd"[85]: exited abnormally: Illegal instruction

The crash is seen as no login windows appearing and the screen in blue eternally during booting.

I will reinstall everything from scratch to try to see if it really depends on the kernel, the bios or whatever other component.

thks for the fix.

j.

Just Wondering, Have Paulicat and Okik disscussed the detail of their pkgs?
No pressure, I am just desperate to hear any progress on the issue and I am willing to do all kinds of testing.

does it works on sse2 intel processors

After trying the packages I do gain 30 minutes more of battery time. That's running the laptop at 1GHz and 100Mhz Bus speed.

Dynamic CPU throttling is not working for me. The CPU stays at 1GHZ though It does seem CpuThrottle is trying to change the frequency of the CPU...it s failing though.

Sleep at least for me is not working or there is no change.

I believe to get sleep and SpeedStep fixed is extremely difficult. I have never gotten it to work trying 4 different computers. (All the way from version 10.4.3)

The kext in m ypkg is not complete, it keeps your bus speed at 100mhz, me and paulicat are working on one which should work for more people

See Okiks post, his first kext had a problem in it which I fixed for mine, however c2d's dont like my kext.
Okiks and I are on the opposite sides of the planet, so its a little tough to co-ordinate, but we'll sort something out asap.

Paulicat.

Just a quick note, in case it helps someone in the future. I installed the latest installer on a thinkpad X60T. In order for it to work on my system, I needed to enable Speedstep in my BIOS. ACPIThrottle reported that CPU0 was throttled to 1ghz, CPU1 had no log messages associated with it at all...

I noticed no difference in battery time, fan speed or temperature with the kernel and Throttle kext installed. Bigger though, my system randomly hung solid, for no particular reason. Removing the kernel and throttle was no problem.

In any case, Paulicat is tops for trying this, despite my machine's outcome! Thanks for the awesome effort!

Hey Aeronick,

Can you post more log info with speedstep disabled in the bios?
Dont work about the error message about acpi not showing and cpu's to control, it doesnt use acpi at all now, it uses the IntelDirect drive...

Paulicat

wow this is quite awesome. After installing okik's package on my core2duo 5600 lappie my xbench score went form 75 to 130 ! Haven't tested sleep jet because I'm to exited
looking forward tot some final version!

thx paulicat and okik !!

Glad it worked for you

well I'm glad too

sleep working?

no, for me..

If you guys can get sleep working ... I would be forever in your debt (you can have my first born if you want it).

you guys can have my right and left nut.

Peanuts...that is.

Damn, i was getting evil plans of attaching them to a pidgeon. (your nuts)

Work is still being done

Thanks in advance Okik, I really wish the new verison of cpu throttle will work not only on core duo or c2D but also on my pentiumD (it supports EIST as well but never works in either yours or Paulicat's pervious verions, always says load cpu failed)

yeah, i dont have that many cpu's to test on, but what i can i will test

I tried this on a Toshiba M400 with an Intel T2400 chip, the speedstep doesn't seem to work. There is one bogus value for P3. P0 though P2 are correct, however.

Here is the log:

Hi, Kiko,
After played with my bios setting, I finally get the cpu throttle worked (kind of ), wow! its now 4AM but I am so excited.

But it seems still something not quite right. I was wondering can you show me some cues.
I am confused with two things now

1. there are so many failure report in my system log, what does it mean?

2. in windows, my cpu can run EIST on following frequency:
2.4G(PID12) 2.6G(PID13) 2.8G(PID14) 3.0G(PID15) 3.2G(PID16) 3.4G(PIO17)
but now it seems the cputhrottle.kext only detect the minimum and maxnium, (in cpu throttle 2 app, it also only reports two states)
any idea to enable rest of states?

here is my log

Wow you P3 is crazy, if only it ran that fast. Good on you Offal, what did u enable in Bios, EIST?

also, throttle fails sometimes becuase it tries to do it to fast, changing the value seems to break it on core 2 duo's i dotn know why it would, but its maybe just me. Testing some more tonight

Speed step works great here.. been working with Kiko on irc and it works well.

Sleep is still a bust for me..

I was wondering why no work had been done to port this to SSE2? Also is there a source patch of the kernel tree anyone can download, you know to tool around with?

well we cant do sse2 yet, as we have no sse2 source, semthex will do that later this/next week hopefully

Thanks Kiko for explainning the failure problem,
that makes great sense! and I am not worrying now
Great job on the previous kext, I really appreciate that !

I found a option in Bios says whether I want to enalbe speedstep function on all processors then suddenly the CPUThrottle start to working.


but, I am not sure what do you mean P3, and why you say it crazy fast
I get a Pentium D 945 which is essentially dual core pentium 4 running on 3.4G with EIST T2M.
I want more than just two frequency (the min and max) but more "steps" when it adjust speed.
do you think it is possible?

Hmm, i dunno, but i doubt it. If your cpu only supports two states then thats all you'll get i guess. You have to enable EST in the bios for it to work, imho.

I'll look into it some more tonight

thanks kiko, I thought that this had been integrated with the SSE3 semthex kernel, and for some reason was not being done this for the SSE2 kernel, that is obviously not the case.

Also what about a source tree for the new throttling kext? I know the one that is currently used was based off the original Neils one for 8.4.1, but a recent one would not be bad. I really want to try my hand at maybe modifying it a bit to allows for defining states based on aribitrary Vcore/multipler pairs like RMClock does in windows.

Finally, and i don't know if this will help with sleep, but i had an insane time with sleep in linux on my laptop. A very similar problem happened, i would sleep, but i woke up, it either did not return the display state, or would crash instantly. So i did something rather simple, I dump the videocard state on sleep, and reloaded on wake, that way i ensured that everything was reinitialized properly, maybe this might help.

here is the script (no credit here, i did not write it)

# discover video card's ID
ID=`lspci | grep VGA | awk '{ print $1 }' | sed -e 's@0000:@@' -e 's@:@/@'`

# securely create a temporary file
TMP_FILE=`mktemp /var/tmp/video_state.XXXXXX`
trap 'rm -f $TMP_FILE' 0 1 15
# switch to virtual terminal 1 to avoid graphics
# corruption in X
chvt 1
# write all unwritten data (just in case)
sync
# dump current data from the video card to the
# temporary file
cat /proc/bus/pci/$ID > $TMP_FILE
# suspend
echo -n mem > /sys/power/state
# restore video card data from the temporary file
# on resume
cat $TMP_FILE > /proc/bus/pci/$ID
/etc/init.d/networking restart
# switch back to virtual terminal 7 (running X)
chvt 9
sleep 4
# remove temporary file
rm -f $TMP_FILE

thanks, i dont know what the issue is with sleep yet, as it works fine for me. But that may help people (if it can be ported to os x)

I would be interested to know, as my machine appears to sleep and wake correctly, except the display never comes back. The machine is fully active - responsive to ping, SSH, and I can access its drives over the network etc. I can connect with a VNC client, but while the window appears (indicating it connected successfully), it remains black.

I guess the key is this line:
# restore video card data from the temporary file
# on resume
cat $TMP_FILE > /proc/bus/pci/$ID

But I suspect that we dont have a /proc on Mac OS X, but rather we need to poke around the IO tree. Anyone got any ideas where I can prod the machine to try to resurrect the gfx?

My two desktop machines do exactly the same thing as Munky's. They seem to wake up succesfully but I only get blank video.
Definitely there's something to investigate down that line.

Ric

often, so does my laptop, that is what this is really for, the videostate is not being reinitalized by hardware, i think they expect "windows" to do it, but alas nothing. So it was the fix.

As for the no /proc, i was reading about it here http://www.kernelthread.com/mac/apme/procfs/, someone tried to port procfs over but with no luck, that does however mean that indeed all the data is there, we just need to get our hands on it.


happy hacking : )
(my 10.4.8 SSE2 ISO just finished, so i am going to try to be more helpful now) I am really just getting to the point where i can really code stuff that matter (just finshed my second year).

Thanks for explaination again, Kiko


It seems to me that cputhrottle can set desire FID to control the frequency.

in the log the
ACPICPUThrottle: rtc_cycle_count=170000000, newcount=170000000, cutoff=50000000

(from what I can see, the rtc_cycle_count may be the part it send FID to cpu and the cutoff it the "step size"???)


Since it only read the min and max FID from bios
so it only sending 2 FID in order to control the cpu frequency


I think one way may slove this question is to MANUALLY set all availble FIDs into cputhrottle
(just my wild guess, forgive me if it is silly, may be modify the kext to make the cutoff=1000000 instead of 50000000 ? to enable all the FIDs as in windows using rightmark utility shown in following screenshot)
,
then wec an force it to use more FIDs (more steps) instead of just 2


Actually I think this is not only me, now the new CD or C2D have mutliple FIDs avaible (and mutilple VIDs, I don't know if cputhrottle can controll that),
but from what I read in this thread, ppl only get max of 3-4 states lisited in cputhrottle kext , which is way less than the avaible ones, if you can manually add all the other aviablet PIDs to cputhrottle.kext , it will help to dynamiclly adjust the cpu speed.

Offal: It is possible to define your own steps in the source, this is what was done with the original speedstep kexts, so you could choose from a full range of FID/VID pairs. Im writing a kext to test, so once i get it working at home, i'll post a beta here

Blinksilver: THe source tree for my kexts is basically nial's kext, just recompiled, with the fsb setting commented out (where it sets the fsb to 100mhz) and states lower than 1ghz enabled, im currently working on a new kext that will be easier for me to understand (as i would have coded it), and should allow full control and cpu state and that will read the available states from the acpi table or by defining them the source

P.S: The kext will take some time, im pretty tied up at the moment
P.P.S: The CPU Throttler App included in my pkg, isnt mine, i do not have source for it so i cant change it. Maybe once this kext is done, i'll write a app to control it

Great to hear back from you Kiko, concentrate on your own stuff first, we will wait for your good news!

Heh, it seems i rushed to much to make my own kext. I think you can just add your own values into the source of the current kext. I'll also play around with the switching time. i'll up it from 10 to 15 to see if it makes a diffeernce

i dont know if the paulicat package to fix the speedstep to improve the battery life work on my Pentium M 1.73.

sorry if tha was posted.
but i have a poor english. XD

Wow,

I step away fore a few weeks and you guys fixed it thats awesome.

I had continued work to CPUThrottler2, but had quit when i found out it wouldnt work in 10.4.8. However, i have a much improved version nearly completed and after my midterm tommorow, I will get seriously back to work on it.

Kiko, i just recieved your PM asking for the source for CPUTHrottler. Let me finish up what I have started and clean up the code and then I will be willing to share it with you.
