Hey guys,

Guess what. Mr Paulicat has done it again. This time he has fixed Semthex's kernel to support Sleep - aka S3 Sleep. Usually , you could sleep the hack , but then if you try to wake it up..It does not. So , Mr Paulicat has found a way to fix it , its simply by creating a patched Kernel to support SpeedStep Extensions and S3 Sleep. So if you're on a laptop , you'll know that you need it soo much

Please bear in mind , this whole thing is 'Beta'. Meaning that , it might or might not work for you.


Please backup your kernel and your Library/StartupItems folder.

Oh one more thing , if you plan to use your Old Kernel back , make sure you delete the ACPI Folder from the StartupItems. Otherwise you'll get a Kernel Panic

Oh yeah , it does not work on AMDs !

Okay , enough of the blah blah blahing . Now lets get back to our topic

Firstly , please make sure you're using OSX 10.4.8 with 8.8.1 Kernel [and please make sure your Processor supports SSE3 Extensions and Intel ® SpeedStep ™ Technology [ this includes the enhanced version found on Core 2 Duo , Core Duo , Core Solo processors]


Link down

3. Install it and reboot . If everything goes okay , you should have OSX Kickin' In. You may want to test Sleep [if it wakes up - kudos] , if it does not [Then I am sorry]. Thirdly , you might also notice that this 'patch' increases your battery life. Whenever you unplug , the processor automatically goes to power-saving mode a.k.a the 'slowest' speed to 'extend your battery life'

It didn't work for me

No wake from any sleep options and I cant see any speed stepping affects. Oh well, I'll keep dreaming....

Why do I have Loading Kext/Finished Loading Kext on boot now???

Thanks, Sleep and SpeedStep works here. Sleep never worked with any of Semthex's kernels for me before (it didn't wake up).
Still need to use cpus=1 though, without cpus=1 system stutters and locks up. Is there any way to fix both cores for some notebooks?

Do you have the Loading Kext stuff on boot with -v??

Ok, I lied. I do have sleep if I let Energy Saver time out, but thats it, no power button and no lid close wake

So close now.... I get the picture of my desktop back, then nothing... HD spins for a bit then it's just a frozen desktop. Before I just got the HD spin and no picture.

dont forget to add that the 2007-02 update messes with this a little bit.

-DiaboliK

Nevermind...

I found the updated CPu-throttler thread... Its the updated and upgraded version...

Didn't works and messed my system (If I try open "Apple SAystem Profiler" from "About This Mac window - the finder are reseted). How I can uninstall it? I deleted ACPI files from the /Library/StartupItems, but the problem remains. Thanks in advance and even the problems are in my system, I appreciate your work.

Yup, exactly the same here!
But i'm not on laptop, maybe this is the beginning for the fix for desktops too....
Good work so far Paulicat.

BiTRiP

Xanthrax go in -s
mount -uw /
rm -R /Library/Startupitems/ACPI..........blabla
then u can run the regular kernel

think this might help my Pentium D920 machine wake from sleep? (see sig for spec)

EDIT: it didnt help. ah well.

in my concerning the kernel + the acpi kext did freeze my core2duo vaio after gui was loaded so i had to remove it...i only could move the mouse cursor after 1 second the DOCK wasnt responding

Sleep only works when I let Energy saver options kick in. Does not work when I put computer in Sleep mode or when I closes the lid - goes to sleep but can't get it out of sleep.

Keep up the good work guys!

Ok, i think I worked it out. If I let energy saver kick in it works (with fans running), provided I wake it up reasonably early. If it's left sitting for a while it will get me only the frozen desktop, same as if I select sleep from the menu.

My theory is that there are two 'levels' of sleep and we are only getting the first stage, the deeper "hibernation" mode is still broken.

BTW, regardless, kudos to you prasys.

This information may be useful to kernel coders looking at this, I hope.

Questioning install of kernel or testing of it:

I am currently running the DaemonES kernel without sleep or speedstep (I would assume). HOWEVER - when I run XBench I get a performance of 80-85 when OSX is booted of my AC adapter. After I go on battery mode, I get a score around 50-60 consistantly. I assume this would be due to speedstep being set to my low frequency (1GHz). CPU performance itself goes from 60 to 30 according to XBench when on battery. When I plug my AC adapter back in, however, XBench score match those of running on battery, and will never recover to 80+ until I reboot (on AC). So:

- Is XBench really a good benchmarking tool for this? When I get a difference between battery and AC performance, is it due to speedstep throttling my CPU and I just never recover on AC, or am I getting flaky results due to XBench itself?

- I get the same results with both the DaemonES kernel (which, I believe, doesn't support speedstep) and the new Paulicat kernel. Does that mean that DES and PC both support speedstep, or is the PC kernel not running properly on my machine?

- Both DES and PC kernels report the same battery life (around 6 hours) on battery, which moves a little erratically to about 5.5 hours and is stable from there, with wireless enable and screen brightness knocked down a few notches. Again, does this mean both are using speedstepping, or neither are?

- Still can't wake from sleep (for what it is worth - just reporting this).

Thought these results might be interesting to build on the progress so far Thanks for the work, everyone! Outside of sleep, the known headphone/speaker issue and possibly speedstep(?), my Dell 640m-acintosh is running perfectly!


EDIT: I have a Dell 640m, Core Duo T2300 - thought I should specify so you know what processor/platform this is occuring on. Thanks!

Hi all,
First things first, the sleep fix was an unintended side effect since the wake function needed to be rewritten to support some of the other changes I needed to make for speedstep.
However, it did fix wake on my laptop so thats why I made mention of it.

As for speedstep, lets make some things clear, any 10.4.8 kernel besides mine has panic calls to speedstepping functions. However, some bioses have speedstep support built in. Mine doesnt so I can't test how it would work enabled in the bios or disabled...but...last night I helped a fellow get speedstep going on his Thinkpad T60 with coreduo. (On that model notebook, it works fine with both cores btw). Initially, he had speedstep enabled in the bios, and it showed 1:30 of time left on the battery. Also, the throttle kext would not load.
So I suggested he disable it in the speedstep. He did, and when he came back, his 1.87ghz coreduo was running at 1ghz, and his time went up to 2:10.
He did say he would try to make a success story post here today.

Now, back to wake, I found something out last night, purely by accident. My laptop loads a kext called AppleACPILPC.kext (plugin of AppleACPIPlatform.kext), I found that I needed to remove that kext in order for my laptop to reboot properly (previously, it would power off instead of reboot).
Once I removed that kext, my laptop reboots properly, however, I noticed I can no longer wake from sleep.
A bit of investigation into what the LPC bus is used for showed me that OSX uses the LPC bus to wake from sleep.
So...long story short, if your pc (laptop or desktop) does not load the AppleACPILPC.kext I doubt you'll be able to wake from sleep on any current kernel.

For Analog: DES kernel is not controlling speedstep, likely, its your BIOS. How the bios interacts with osx I can't say.

If anyone has any other questions, put them here and Ill do my best to answer them.

Paulicat.

Pentium Ds 805 & 820 do not support speedstep (EIST). I don't think that AppleACPILPC.kext gets loaded (can't see it in sys profiler anyway) on my computer. So sounds like you need a least an 830 for dual or a 630 for a single to get desktop sleep. Note: EIST is not available on all cedarmill revisions, some 6x1s have it disabled due to a fck up by Intel.



P.S. http://en.wikipedia.org/wiki/Low_Pin_Count

I have a Pentium D 945, which support EIST TM2 C1E (so inhanced speedstep is supported, so does the S3), after I installed the kernel and startup Item,
first time there is a warning after reboot says the ACPI folder has something doesn't match securty check, need to be fix and reboot

then I am able to going to sleep, during wake up, the desktop shows but mouse freeze.

It's great progress though, Thank you Paulicat!

about loaded kext, I used ioreg to check (I am not a experienced mac user) and didn't see any entry for AppleACPILPC so I guess it is not loaded, is trying to load it manually will help?

As to speedstep, I feel my CPUs is not slowing down and overheat, but I have no way to know the realtime frequency VID or PID,

Paulicat, I was wondering Is there a way that I can see my real time cpu frequency?
I tried several apps (temp monitor, cpu throttle.... ) but none works,
I guess the Reggie SE may work but it seems to complicated


Any cue how I can monitor the realtime frequency or VID PID?

Paulicat, thanks for the information

That's interesting about the bios controlling the speedstep. Definitely good to note! I don't have AppleACPILPC.kext, which could definitely be a leading reason I can't get my computer to sleep. Is there a source I could use to snag the AppleACPILPC.kext from, off hand to try to sleep with?

Thanks again, Paulicat! Your work on this is appreciated by many on the board, including me

Have you looked INSIDE AppleACPIPlatform.kext?

hey paulicat, its working great on my commell lv-677 mobo with a C2D memrom 2ghz.
i helps prasys intitally when you first released it.
i have only one problem. the restart doesnt work i have to hard restart.
sleep and speedstep work greak eventho its a desktop and i dont really need it. it also enabled sleep on my once sleepless 7600GS.

Thanks for your great work!

on another note can you supply me with the help i need to fix the smbios to read ddr2 memory again?

-DiaboliK

The reboot problem is odd, and Im not 100% sure its not a screw up from my part. I was trying to fix the reboot problem I had on my laptop (powering off instead of rebooting) and I might have left some code in that I was testing.

Prasys has a new build from me and will be creating an installer very soon. The first installer might have been messing up the StartupItems folder so he's removed it and recreate it very soon.

Keep the reports coming folks, Im really glad to hear its helping some of you out!

Paulicat

Well, I feel like a fool. Thanks! I assumed spotlight could search inside of a kext. I guess it doesn't look inside packages like that.
Thanks! I found it! Too bad I still can't sleep :/ Ah well!

Is there any other similar solution for AMD systems?
My notebook runs very hot too.

Ric

Ok I got this version from the IRC Channel. It didn't come with any instructions. But I installed the Kernel and the system seems to work. I also added the ACPICPUThrottle to the Startup folder and repair all the permissions.


Can anybody tell me the best way to install ACPIThrottle and how to test that it's working?

New Installer with working start-up item and cputhrottler beta2 included (installed to you applications folder)
http://tinyurl.com/32yfg3

Just add few more things to my original post (see upper part of this post), I can cofirm that the AppleACPILPC is loaded.

but the speedstep seems still not working. but it's hard to know since I have no way to tell expect the behavior of cpu fan

I (and seems most people on this thread) doesn't have a objective measure of the speedstep behavior

A tool to monitor real time frequency/VID/PID measurement will be really handy to see the effect of speedstep control

any suggestions? cues?

Progress !!

Installed Paulicat kernel w ACPIthrottler. I can put my laptop to sleep (from menu) and my screen "wakes up". I have never seen this result from 10.4.4 to 10.4.8. Unfortunately system is "frozen" after screen on and I have to do a hard reboot.

Also tried without ACPIthrottler in startup folder with same result.
Also tried removing "keithpk power management bundle" w same result.

Notice one post saying they have this working on a dell w NVidia graphics ...

Anyone else with a Dell 6400 get this working ...?

Cheers ...

Dell 6400 Core DUO T2300 (1.86GHz)
GMA 950 graphics
10.4.8 w semthex beta8 sf9 or paulicat kernels

trexplorer: I use keithpks powermanagement bundle also, it works for me...however, it might take a little while before it fully wakes (I've heard upwards of 5 minutes). For reference, my wakes within a minute...

offal: Its pretty easy to monitor temp, google Temperature Monitor and get/install bresinks app. How I know that its working (besides doing sysctl -a | grep curfreq) is that my temperatures float at 55C rather than without speedstep they are always over 62 and climbing. Without speedstep my fan comes on every 40 seconds, and I get about 1.5 hours of battery. With speedstep my fan does not come on unless Im stressing the cpu and I get about 2.75 hours of battery life. All in all, its a pretty noticeable difference between the two.

ppan: easiest well to see if everything is installed and working properly is to do sysctl -a | grep throttle in Terminal. If everythings working proper, and your cpu is generally idle, when you run that command it will give you a value that will be less than your cpu's max as the curfreq, and also a list of available frequencies.

Ill be back as soon as possible, but in testing a new kernel with sleep mods, and being a little tired, I've pooched my laptops install. Thankfully, I don't do development work on there anymore and all the source is safe and sound. I might not be available on irc or here for the rest of today.

Paulicat.

Thanks for the tip. Unforutnately mine just crashes and tells me I have to reboot if I wait long enough (i.e., 12 minutes).

Keep up the good work.

Cheers ...

will it works with AMD too?
harry

Any other links to this other than the one thats down?

Also anyone tried this on a dell e1505?

Keep up the good work.

haribo: AMD is planned, but not working currently...

trexplorer: Bloody Dell laptops I really think their bioses are the cause for the majority of the problems...not sure what else I can do for them...

naldo: there should be a link in the channel topic for the latest manual install version. Or, if you want to try Okik's installer he posted just above here in this thread.

Keep you posted when I get my laptop working again...

By the way, any mod wanna make this a sticky seeing as how this is the only 4.8 kernel/thread going on for speedstep?

Paulicat.

Dell E1505 and 6400 are the same laptops ... See my comments in above posts.

Cheers ...

please make AMD users happy
harry

This package installs ACPICPUThrotttler in the \LIBRARY\StartupItems folder. Is this correct?

I am almost 80% sure ACPICPUThrottler is supposed to go to the \SYSTEM\Library\StartupItems folder.
-------------------------------------------------------
I guess I was wrong and it's supposed to go to \LIBRARY\StartupItems after all

Here is my results

So my CPUfreq is reduced to 1GHZ. Which is great!! Also It does seems that my fans are slowing down. By the fan noise.

I installed Temperature Monitor as Paulicat was saying and the temperature for the CPUs stays at 53-54C. Once it reaches 60-64C the fan stars spinning and the temperature drops. Then they slow down or shut off. But this seems like a never ending cycle. It seems is 0% fan or 100% fan. So it goes like this fan on for like 10 minutes then off for like 10 minutes.. then repeat.

I have a Core Duo Processor, CPUThrottle seems only to be working on one core?

Thanks for the great work. I have been waiting for this forever.

I have not tried the sleep function yet. But crossing my fingers

Here is my result with sleep.

I dont see any changes to the laptop sleep function. The screen goes blank and I am unable to wake the computer up. It also seems the fan goes to 100% when trying to go to sleep.

And it also seems to be inconsistant. My notebook has a keyboard shortcut to put the laptop to sleep (FN+F5). The laptop seems to go to sleep (HD, Screen and FAN). Then after about 1 minute it will wakeup. Yes the screen comes back, wireless comes back, but I cant do anything. Mouse and keyboard not responding. And sometimes it just decides not to wake.

Which means that ACPILPC is loaded.

So no luck for me with sleep/wakeup.
At least SpeedStep is working!!.

Stickied as requested. I'm really hoping to find a solution to my particular sleep issue. The machine appears to sleep and then wake normally, but the monitor never powers on. Weirdly, the machine will respond to ping, ssh etc - I can remotely login. I try to connect via VNC, and while it does connect, the window remains black.

Any thoughts?

Ok - still can't wake up (played around a bit and waited for 5 minutes). Same issue - computer is "awake" except for the screen. Ah well.

Paulicat: after using the "syscnl -a" command, I found that the original DES kernel only shows the max-min frequencies as my max and I was "always running at that frequency" (outside of BIOS handling things without OSX knowing it, perhaps). I reinstalled your kernel and it switches between 1.3GHz and 1.66GHz (I've run it under idle and load and it definitely is switching states), so that does seem to be acting nicer for my install I'll have to actually run the comp. under heavy load with both kernels and ignore my battery estimates for now to determine which will win.

I do have 2 questions though, and I appologize in advance for asking. I've spent about an hour searching the forums to no avail:
1) as per the question above, I noticed my ram is also being detected as DDR instead of DDR2. Does this matter? If so, how can I fix this?
2) my system's true FSB frequency is 667MHz (max, with 553MHz DDR2 installed). Applying the "divide by 4" rule, my FSB should be set at 166MHz for 667MHz or 133MHz for 553Mhz. That being said, "syscnl -a" shows my fsb is 100MHz. Am I losing performance here? If so, how do I fix this? I used the "fsb=133" in my com.apple.Boot.plist, but it still boots into 100MHz FSB.

Thanks! I'll report back with actual battery times soon!

This is the system log when the laptop decided to wakeup (Only the screen)

Hope all this logs helps one way or another

Reading the logs made me realize that CPUThrottle is not working correctly as it cannot change the power state of the CPU. CPUThrottle tries to change the power states (State 0,1,2) But according to the logs it fails.

So the CPU stays in Powerstate mode 2 (1GHZ)

To Control the frequency use the included CPU Throttler app in my installer, you can either set it to dynamic or manual, (dynamic changes your frequency according to your cpu load, and manual lets you set it youself). Also, Bresinks temperature montior is weird on my computer,. When i had old 10.4.4 SMBios installed i always got temp raitngs of 45C (where it should be) using new paulicats smbios i get ratings of 52C (so most likely just a 10C bias), just keep that in mind.

Theres something very weird going on there.
Im going to test out the kext thats in that link, cause I got a strong feeling that is NOT the kext I've distributed.
I'll report back as soon as I test...

Paulicat.

EDIT: As I suspected, that is NOT the kext I distributed with my kernel. I'll be making a package shortly with my kernel and my modified kext. Ill update this post with a url shortly.

paulicat, the kext in my installer, was not the one you distributed, i had to edit it a bit to make it work on my Core 2 Duo's, it also worked on all my other Pentium 4's. (3.0ghz sse3) and on my Core Duo laptop. I can make a pkg with the kext u distributed in it as well, if thats what you want.

Ok, well heres an installer of exactly what is on my system right now.

http://tinyurl.com/26emuu

Okik, can you tell me what you modded (pm or irc if you prefer) , because I had to mod it to make it work with 4.8 in the first place...

Paulicat

Okik, what temp are you getting off your laptop with speedstep? I am getting 65 at idle and it goes to about 74 when using the computer. Mine is a Core 2 Duo.

for my core 2 duo, i get 53C reported (but take 10C off that for bias) and it = 43C. I think bresink adds a couple of C to it, because 74C is crazy, that'd burn a chicken. If you can, load up the cpu heaps in Mac OS X, then look in ur bios (if u have a heat sensor)

Paulicat, i'll try get to irc this afternoon, as here (at college, we have a firewall). If i miss you i'll send you a PM, but basically its just the source code off niall's site.

Okik, can you pop in irc now? Im curious to know what you changed?
Cause I can tell you you missed one thing in the kext that I found even before I started working on the kernel.
Lets swap code dude...

Paulicat.

Ok, i'll skip last class, and head home now. I'l be home in about 1-2 hours max. Cya

haha, dude, I didnt mean to say that you should skip class bro

Ill be on for the next 3 hours...

Ok I tried both of the packages and it seems I am getting better results with Okik's "modified" kext.

Results with Paulicat's:
