need help with speedstep

mcarswell · March 4, 2012

Hi all, If anyone can help me with this problem it would be greatly appreciated.

I'm running 10.7.3 on an Asus P8P67 Evo board with an i7 2600k cpu. everything is working great except i can't get C/P states to work. my bootloader is chimera 1.8 and i have a custom DSDT and SSDT, and patched AICPUPM.kext. My LPC device ID is already in AppleLPC.kext and AppleLPC is loading (checked with kextstat). I get this in the kernel.log:

ACPI_SMC_PlatformPlugin::pushCPU_CSTData - _CST evaluation failed

ACPI_SMC_PlatformPlugin::registerLPCDriver - WARNING - LPC device initialization failed: C-state power management not initialized

and this in bdmesg

Read HFS+ file: [hd(0,2)/Extra/DSDT.aml] 35744 bytes.

Read HFS+ file: [hd(0,2)/Extra/SSDT.aml] 2829 bytes.

ACPI table not found: SSDT-1.aml

FADT: Restart Fix applied!

FADT: Restart Fix applied!

FADT: Using custom DSDT!

ACPI CPUs not found: C-States not generated !!!

ACPI CPUs not found: P-States not generated !!!

Added 1 SSDT table(s) into XSDT

checking with MSRDumper i get 2 states: 16 and 34 (no turbo, which is set to manual 43 in bios)

Any ideas what i should try to at least get turbo working?

Thanks!

If your custom SSDT has P and C states, you don't need to enable the "generate states" options. If you want to use them, add scope _PR to your DSDT with processors definition.

By the messages in your log I guess your SSDT.aml doesn't have C states.

thanks for the reply. i added the processor definitions to my DSDT and that worked, but caused a kernel panic because of mismatched P states in the SSDT. i deleted the SSDT and booted ok with this:

but i'm still only getting 2 states, and these error messages in the kernel log:

ACPI_SMC_PlatformPlugin::pushCPU_CSTData - _CST evaluation failed

Did you take those definitions from your original SSDT?

Did you enable GeneratePStates too?

mcarswell · March 5, 2012

i got the processor definitions and my SSDT from this thread: http://www.insanelymac.com/forum/index.php?showtopic=253642

i assumed they would be the same as mine since they're for an i7 2600k also. I compared them to the SSDT i extracted from my system and they look the same.

I removed everything from the scope _PR section of my DSDT except the processor definitions and got rid of the ACPI_SMC_PlatformPlugin errors, but i still have this error.

ACPI_SMC_CtrlLoop::loadStepperContext - pmCPUControl (pmioctlPStateContext_t) failed, result = 0x16

I removed the GenerateXStates options from my boot.plist and put the SSDT back in /Extra and have 5 working Pstates now: 16 35 36 37 and 38.

Maybe this is the best i can hope for?

Cassio · March 5, 2012

Get the definitions from your original SSDT, it depends on the motherboard (BIOS), not on CPU.

mcarswell · March 5, 2012

Thanks again for the reply. Can you tell me if this is right?

This is the scope _PR from my DSDT:

    Scope (_PR)
   {
       Processor (CPU0, 0x01, 0x00000410, 0x06) {}
       Processor (CPU1, 0x02, 0x00000410, 0x06) {}
       Processor (CPU2, 0x03, 0x00000410, 0x06) {}
       Processor (CPU3, 0x04, 0x00000410, 0x06) {}
       Processor (CPU4, 0x05, 0x00000410, 0x06) {}
       Processor (CPU5, 0x06, 0x00000410, 0x06) {}
       Processor (CPU6, 0x07, 0x00000410, 0x06) {}
       Processor (CPU7, 0x08, 0x00000410, 0x06) {}
   }

If I use DSDTSE and extract the SSDT, i get this:

also i just noticed that something i did while working on this has caused sleep to no longer work right. when i sleep the computer, the screen goes black but the fans stay on, and it won't wake back up.

...frustrating

It's correct, you just used CPU0 instead of P000 (and so on), but I think it's not a problem.

Try using this plist in /System/Library/Extensions/IOPlatformPluginFamily.kext/Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/Contents/Resources http://Olarila.com/forum/download/file.php?id=1491

i'm pretty sure i had done that, but i did it again just in case. i figured out why my sleep stopped working. deleting the method _CST from my DSDT made the errors go away, but broke sleep. any suggestions how i should modify it?

        Method (CST, 0, NotSerialized)
       {
           If (LNotEqual (And (PDCV, 0x0200), 0x0200))
           {
               If (LEqual (NCST, 0x02))
               {
                   Store (One, NCST)
               }
           }
           If (LEqual (NCST, Zero))
           {
               Return (C1ST)
           }
           If (LEqual (NCST, One))
           {
               Return (CIST)
           }
           If (LEqual (NCST, 0x02))
           {
               Return (CMST)
           }
           Return (C1ST)
       }

I would let Chameleon generate P and C states.

mcarswell · March 7, 2012

Yeah, i would rather have them generated automatically. i'm working toward that now. got rid of SSDT.aml and put GenerateCStates and GeneratePStates back into org.chameleon.boot.plist.

what i'm trying to figure out now is why sleep stops working when i remove the Method CST section from Scope _PR in my DSDT, and how to put it back in without causing ACPI_SMC_PlatformPlugin errors.

Cassio · March 7, 2012

Have you tried leaving only CPU definitions in scope _PR in DSDT? You can remove all the rest, _CST and _PSS will be generated in SSDT by Chameleon.

mcarswell · March 7, 2012

yeah, when i only have the processor definitions speedstep works but sleep doesn't work right. with the Method CST block in there sleep works, but i get ACPI_SMC_PlatformPlugin errors and only 2 speeds, 16 and 38.

surfcaster · March 7, 2012

same problem, GA-Z68MA-D2H-B3, i5 2400, only 16, 34, Chamaleon only generates C-states

amone_78 · June 13, 2012

Hi all! please i have a same message on boot screen:

acpi_smc_platformplugin start waitforservice resourcematching appleintelcpupowermanagement timed out, and i don't know if the used patches are working for my system config,

Please if there is something to do to DSDT

here is my patched DSDT.aml, and original acpi Aida 64: dsdt and ssdt from windows7
