Enabling native Speedstep on core 2310m

[blueking]

I would like to be able to use the vanilla AppleIntelCPUPM with my CPU.

I see this on boot:

Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=0 LocalApicId=0 Enabled
Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=1 LocalApicId=1 Enabled
Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=2 LocalApicId=2 Enabled
Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=3 LocalApicId=3 Enabled
Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=4 LocalApicId=0 Disabled
Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=5 LocalApicId=0 Disabled
Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=6 LocalApicId=0 Disabled
Jan 29 00:38:55 localhost kernel[0]: AppleACPICPU: ProcessorId=7 LocalApicId=0 Disabled

So I think this has something to do with it?

Here is my DSDT, do you see anything I can do with it?

That means you have four threads (i.e. 2 cores x 2 threads per core = 4 threads) in your processor. If you had an i7 with 8 threads, all ProcessorIDs would be active. Regarding native AICPUPM, is the issue a KP on boot? Does the flAked Speedstepper fix solve the KP problem?

Ah thanks. So not a problem.

And yes, it kernel panics on AICPUPM.

The flAked Speedstepper does solve the KP problem.

So knowing that fixes it, is there a way to patch for native?

It is a problem in all AMI BIOS. The problem is not present in Award BIOS (Gigabyte). The fix is to patch the AMI BIOS or patch AICPUPM; the dsdt has no effect on the problem. flAked has a patch for 10.7.3 AICPUPM and it works on my P8H67-I-Deluxe. Once you get AICPUPM to load, many other system requirements must be satisfied for native SpeedStep (AppleLPC, SBUS, CIST, SSDT, etc.). SpeedStep is working when Turbo Ratios like 1234 or 1378 appear in Console on boot and when IOReg/CPU0@0/AppleACIPICPU/ACPI_SMC_PlatformPlugin shows the following:
1. AICPMVers
2. CPUPLimit
3. PerformanceStateArray.

Hi, I also have a i3-2310m. I want to enable speedstep on it.

I already have a motherboard specific DSDT.aml patched (found on olarila.com). In additional patching AICPUPM.kext, What else do I need to do to enable speedstep?

I found several "speedstep" DSDT patches on (http://olarila.com/forum/patches.php), do i need to add those patches to my DSDT.aml, if I do, which ones, there are several speedstep DSDT patches.

Hm. Is there a decent guide anywhere as to how to do that?

Not that I'm aware of. When you have AICPUPM loading, attach a copy of IOReg and the part of Console boot log with any AICPUPM messages.

Speedstep is working. Run MSRDumper to see P-States dynamically http://www.insanelymac.com/forum/index.php?showtopic=258612

Alright thanks.

So nothing to improve on here? Its working fine, and I can't make it more vanilla then the speed stepper?
