Chameleon RC5 mode with mem detection enabled and automatic P-States & C-States generation for native power managment

Recommended Posts

If you experienced a problem patching your DSDT/SSDT to enable Mac OS X native power management, or you don't know how to do this - the new bootloader is for you! Should work on most modern systems/processors.

 

Bootloader based on latest Chameleon RC5 rev184. Mem detection is enabled and slightly modified: fixed system profiler returns error while reading memory info in some cases. P-States & C-States are exported to the system via additional SSDTs, so if you have native SSDTs with _CST methods you should use "DropSSDT" = "Yes" option in boot.plist. If you have modded DSDT with _CST methods you should remove them or it'll be kernel panic on system start. The bootloader also supports multiple SSDT loading (names should be SSDT.aml, SSDT-1.aml ... SSDT-29.aml). Bootloader also supports latest graphic cards (code was obtained from here)

 

To enable native power management you should use proper mac model + HPET enabled. To enable C-States you must have LPC working on your system. It could be enabled via DSDT mod or injector.

 

To activate P-States generation add "GeneratePStates"="Yes" option into boot.plist. To activate C-States generation add "GenerateCStates"="Yes" option into boot.plist. Those features are not activated by default!

I felt this days ago, when we talked on the other topic .. and it works amazing on my q9300 (only on this i have try for now). I have remove ss code in dsdt,, great! :(

 

Thanks for this.

I've been hearing the buzz about this.. and have just downloaded the source. I'll build it tonight and test with it when I get home to my hack. But great job Mojodojo :)

I have already native speedstep with my MSi board but have to add _CST data to DSDT.

Will give this a go tonight.

 

Really glad to see this implemented to Chameleon.

Nice one mojodojo :)

Well after many trials I can't seem to get it to work.

 

I can have native power management when using either Cartri's modified Gigabyte BIOS, or standard Gigabyte BIOS with my DSDT patched with _PSS / _CST info. But not with this modded chameleon bootloader, using standard Gigabyte BIOS and DSDT without _PSS / _CST info.

 

AppleLPC loads by default on my board and doesn't need to be patched.

 

If I manually add patched SSDT tables to /Extra then I can see in VoodooMonitor my Multiplier changing and the CPU temps come down, but voltage doesn't change. But I am missing PerformanceStateArray from ioreg.

So am I right in saying the P-States and C-States aren't working automatically for me with this bootloader mod, but manually adding correct SSDT tables to /Extra enables C-States?

 

If it helps, I have attached the SSDT tables I am manually adding to get the C-states, as well as the SSDT tables extracted from the running system when just using the modded bootloader without the manually added SSDT tables.

blackosx, the problem could be in your patched DSDT, if it has different CPU names from CPU0, CPU1 ... CPUn. The fix almost complete, need to back to home to finish it.

 

P.S. And you have already SSDTs with _CST, this is a problem. You need to DropSSDT or not to use GenerateCStates feature.

Thanks for the quick reply mozodojo.

I think that must be it!.. As thinking about it, I quickly removed the _PSS / _CST info last night from my patched DSDT and must have missed adding back the default CPU declarations.

 

I am at work now and will have a look at it again this evening and report back. I did play with the DropSSDT option last night and I'll remember to double check the setting again tonight.

 

Thanks for the help :(

Hi mojodojo

 

Not having too much luck here either.

I have tried with original scope _pr, with and without CPU alias removed (actually no KP now with CPU alias, which is great!) and have tried both, with and without DropSSDT=Yes

 

Either way I get _cst evaluation errors again and significantly higher temps.

 

ApplePLC is loading.

 

EDIT: - Using iMac9,1 and Speedstep continues to work, but works naively anyway.

 

Thanks again for the hard work.

same for me. cst error if I don't inject them

sorry for the noob question,

how does one know if this is working, or if it is needed, where to check, is there a test?

thank you

Hi Mozodojo

 

Sorry to report but I still don't have success. If you get time, I have attached some files for you to look at to hopefully see what's going on. The files are:

 

• DSDT file I use for power management when using normal Chameleon

• DSDT file i am using when booting your modified Chameleon

• Extracted ACPI tables from my system booted with r346 using both DropSSDT and not.

• Extracted ACPI tables from my system booted with r350 using both DropSSDT and not.

• Screenshots of ioreg showing LPC and APCI SMC PlatformPlugin

• kernel log when booting from r350 without DropSST

 

If there's anything else I can supply then let me know.

Thanks

I am not sure how the new Pstate/C-State generator works.

But the Adress of the Control Register is on some mainbaords 0x4xx and some 0x8xx (400,410,415, 416 like my EP35 vs 800,810,815,816). Maybe here is the problem ? (patched DSDT works, chameleon PStates gen not).

Great Work mojodo !

 

Thanks especially for fixing the system profiler problem happening on few systems, I couldn't figure that alphas-digits-only-char-allowed problem :)

 

We could improve the memory detection speed as well, by reading only the headers instead of a full spd page and finally read it only when a slot is not empty.

 

I wanted to improve that myself after my first mem detect impl., but found a (great) new job sucking all my development time & energy right now :)

 

Keep on the good work !

sorry for my silly question....how can i compile it? i'm a newbie and i want to try since i want to get ride of cpuinjector kext to get my cpu recognized....is there any tutorial or some one good pal can tell me how to do it? my cpu it's a core 2 duo e7600 same on imac 10,1 bot no one loader recognize it...it's always unknown on about this mac and no info on system profiler....but with my old cpu e4700 was detected proper....can some one give me a hand?

Thanks a lot!

Install XCode from your OS X install DVD. Open Chameleon.xcodeproj in the 'Chameleon/Chameleon-Mozodojo' folder. Go to Build in the main menu, and build it. Right-click the sym/i386 folder on the left pane and choose 'Reveal With Finder'. Copy the 'boot' file to the root of your main drive.

 

Reboot.
