Testers needed: CPU Power Management for SB and IB Xeon(s) or i7-39xx on X79 or C60x chipset

[shilohhh]

friend your score it is very high 23,854 ( 4400 oc ) mine cpu to 4700 only 23982 this is a very strange

Maybe because I have 32Gb ram @ 2133 cas 9. This score is normal with my OC in 4206 and GeekBench 3.

or maybe i use again NULL CPU ?

To address some of your questions:

 

- AICPM I provided you with *is* from MacPro6,1 build, there's no other that you can get or need - this one detects the IB Xeon in MacPro6,1, all others don't.

 

- I *have* a Xeon E5 2.6GHz 8-core (two of them) and with it and my patched AICPM, my GB3 scores double. This tells me that at least my Turbo works. But also my CPU packages idles down to 10-11W which also tells me that it steps down, too. I also have a physical temperature monitor on my fan controller and it shows a drop when running this patch vs. no patch.

 

- I never said there are any guarantees this would work, especially with i7 Core-E chips. My guesstimate was (and still is) that because the cores of those chips are very close to Xeon ones (they lack SMP) it should basically be the same deal.

Your Max Efficient Power State is the lowest clock state your CPU can do, so look at your SSDT.

Hi Omni,

 

I'm sorry. Apparently i missunterstood stomething. I tought you took the "old" AICPUPM and patched it, so that it recognizes the xeon e5.

 

I also have the Xeon E5-2690 v2. With your patched versions i also have fully working turbo states. Only downclocking and C-States are not working.

Could you provide an unpatched version(stock kext from macpro6,1)?

 

Do you have working p-state reporting in HWmon and/or AICPUPMI by Pike? I especially mean between 1200Mhz and stock frequency. (e.g. 3000Mhz).

 

Doing crazy things with my SSDT i also get very low power/wattage and working turboboost. But the P and C States aren't correctly recognized by HWmon and AICPUPMI, but with IPG. (I posted a screenshot).

 

Could you tell us, what and why you patched the stock kext? Did it kernel panic?

 

I think with the right SSDT the stock version shouldn't panic. therefore i would like to try the stock kext.

 

Could you also upload your SSDT? Did you use pike's script to generate it?

I'm a loss for understanding. With Rampage IV Extreme BIOS 4206 I had to use CodeRush's fix to unlock MSR E2 and the v2 patched AICPUPM worked without KP but v3 gave me KP within 2-3 seconds. I updated to BIOS 4802 (MSR E2 is unlocked from Asus in this version) and I can now use v3 without KP. In IOReg the X86PlatformPlugin is loaded with all CStates enabled and all PStates listed but my 3930K is locked at 12x and HWmonitor reports CPU Temp=23c & CPU Package Cores=3.92W @ idle. Under load the CPU Temp=35c & CPU Package Cores=24.58W Geekbench=6,763 so it's definitely not stepping from 12.

However, if I do anything that causes X86PlatformPlugin not to load like change the Plugin type to Zero, @ idle,  I jump around between 32-44x, CPU Temp=24c & CPU Package Cores=6.3-7W. Under load I stick at 44x, CPU Temp=55c & CPU Package Cores=53W and my GeekBench goes back up to 23,854. Of course the X86PlatformPlugin isn't loaded so there is no C or PStates reported in IOReg.

Any suggestions?

I'm not sure it's correct to do this, but try adding APLF to your SSDT. 

 

On another note, I noticed  AICPUPMI reads your max turbo freq correctly.  Mine reads 5700 no matter what I do.  Can you attach your SSDT for me to check out if you don't mind?

I have tried APLF 1 & 0 with the same results. I have tried manny ssdt variations including modifying the R4E 4802 stock with correct freq vectors and the same with the stock ssdt from MP6,1. Currently I'm using non turbo values up to 3200 from stock R4E (it had nothing above 3201 in it) with turbo values (only above 3200 up to 4401) from pike in pikes SSDT. I had to add 4401 above 4400 to match what the stock r4e values were doing at the top. I don't think we're dealing with an ssdt problem. According to omni, the patched kext may not work for our 3930.

I used APLF 0x04 because I read somewhere that it equates to 1200. I'm not overclocked though so perhaps that makes a difference. Right now my system idles at 32x but with wattage equal to what I'd get at 12x and turbo up to 38x. My geekbench score equals what it did before on bios 4206 and nullcpu at 38x max turbo. I'll do some testing tonight with an OC and check the results.

[shilohhh]

@kundica

Our stock ssdt starts at 1200. Pikes starts at 800 and adds one extra state between all the others. That's why I used stock states up to turbo and 0. With values starting at 1200, 0=1200

. According to omni, the patched kext may not work for our 3930.

 

good news, what a disappointment I had now,......uffff

[omni]

@magnfico,

 

Don't despair, there's still a possibility to get it working because the CPU cores aren't really that different.

 

 

I posted a "virgin" version of AICPM for anyone who wants to help out in the OP.

 

What I patched were routines for processor matching and then some init methods that were causing KPs because my Xeons don't have those MSRs. Obviously, if IB Xeon has them they could be used, but I'm not sure it would make a difference really.

 

The work is not done, as there's probably more things to be possibly patched, I just have limited time at hand.

 

We need to get someone with a real MacPro6,1 (nMP) to run Pike's AICPMI so we can see its MSRs and then compare to what we have.

Yeah, I'm using stock states, there's 27 from 1200 to 3800.  My APLF is actually "One" so I was wrong about what I said before.  

 

I just tested with an OC to 40x and it behaves like it does with turbo at 38x.  System idles at 32x but with very low wattage as if it were at 12x (like 17W) and if I stress the system it'll move up to 40x. HWMonitor at times occasionally shows idle freq jump down to 12 but barely.  IGP shows the system idle at 3.2ish.

[Klonkrieger2]

Hi Omni,

 

thanks for posting the "virgin" AICPUPM. it works fine with my xeon e5 v2. No patching necessary! But as you already supposed: no visible changes at all!

 

Different SSDT variations bring the same results as with your patched version.

[omni]

Does it show Unknown CPU though in the kernel log or not?

 

There's more lower level debugging needed to figure it out, most likely remote kernel debugging of the kext itself to see what values are passed around etc.

[Klonkrieger2]

the cpu gets recognized, so NO "unknown cpu"

 

Turboboost even works for me, without registered P-States in ioreg. 

So it seems, even if they are registered correctly, they aren't really used by AICPUPM. Who knows why not...

 

IOreg tells me, my bus-frequency is 0xfffffff. the macpro61 ioreg has a normal value for that... may that be an issue?

[shilohhh]

THIS IS WRONG: AFAIK, One=1300. I think it counts up from Zero.

 

I think Zero was locking me at 1200. If I add 1100 and use One, it works like yours. AICPUPM reports 12, 32 & 44.

 

Omni's patched AICPUPM is definitely doing something good for us (3930K) in the OS. If I use stock AICPUPM I'm locked at 32x, 62w & 43c. If I add NullCPUPM to stock AICPUPM I get 12 and 32 (4802 BIOS) Idle @ 10.6w & 29c. Load @ 101w 53c and geekbench 17.4k. Similar to 4206 with NullCPU but without the turbo OC. According to wattage, heat and GeekBench, Omni's patch allows Turbo and OC to work in BIOS 4802 (Nothing else does) and as a matter of fact it appears that CPUPM is fully working BUT ONLY if I keep the X86PlatformPlugin from loading: AICPUPMI reports only 12 and 44 (HWMon only shows 32-44 & bounces around allot), idle @ 6w & 23c. Load (Prime95 torture test) @ 164-181w (from IPG because HWMon cant show anything this high), 58c & geekbench=24k. Again, this is ONLY WITHOUT X86PlatformPlugin loaded and my logic says it should be opposite.

Edited January 24, 2014 by shilohhh

[omni]

Interesting, my bus-frequency is also 0xffffffff on all CPUs in the IODeviceTree, but I wonder if this is because something is missing in SMBios.plist or not.

 

X86Plugin looks at that P-States array to at least determine the maxGuaranteedTurboPState so it must be in use.

[Klonkrieger2]

hm.. I even added SMbusspeed to smbios.plist but this didn't change anything. Also i tried to edit the chameleon source code, but I'm not a good coder at all..

 

bdmesg tells me:

AppleProcessorBusSpeed:

ProcessorBusSpeed (QPI): 25.4GT/s

 

But this should be 8 GT/s for my CPU i think

oh my gosh... i just installed chimera boot loader, which gives my a correct value in ioreg for bus-frequency and look:

Suddenly reported C3 cores and C6 package residency!!! Also power wattage and temperature went further down! 

 

But, my cpu speed is not properly recognized. 3,1Ghz instead of 3,0. I will now try some older chameleon versions...

 

Edit:  Chameleon r2269 works. correct speed detection and bus frequency.

[Klonkrieger2]

AppleProcessorBusSpeed:
ProcessorBusSpeed (QPI): 0.0GT/s

This is bad. SSDT and chameleon plist files won't help here. please install Chameleon r2269, for example with Chameleon Wizard.

[kundica]

Thank you Klonkrieger2,

 

please, could you indicate which flag i have to select in Chameleon Wizard?

I think he's saying to use Chameleon Wizard to change versions. I wouldn't use it to edit your smbios. You can, but you're better off just editing it yourself to ensure it's correct.

 

[Klonkrieger2]

maaannn...i don't know what has happened, but after shutting down my pc yesterday I don't have c3 states anymore.

 

But if I boot in safe mode (-x) I do have c3 states??? What kind of sorcery is this?

 

Even C6 states on core 0 and 1 are not guaranteed... I have no clue what was going on yesterday.

 

Hm.. after installing chimera and rebooting, my system automatically booted in safe mode and did reset some things. (icon/application link and the warning when starting a application, that it's from the internet)

Has someone an idea what did happen??

[omni]

New build 13C44 of 10.9.2 now includes AppleIntelCPUPowerManagement.kext.

 

It is the same size as the one I put in the OP, but perhaps there are other changes inside.

[Klonkrieger2]

Thanks for the info. no changes to PM after the update for me. But i should probably  do a clean reinstall, something seems to be really messed up

[Balamut]

@omni: With patched AICPM, there is a small lag between the CPU power jumps, with the latest OG jump is much faster, also for some odd reason MSR 0xE2 is now  0x403 instead of 404, weird.
 
@fabiosun: I can bet x86Platform didn't load

[Klonkrieger2]

Did anyone else notice this ioreg entry in the original macpro61 ioreg?

"PLimitVersion"=3

I don't have this in my own ioreg, so maybe thats something important, we miss yet?

 

I disassembled the x86platformplugin and found the ascii string "pliimitversion" in here. Maybe someone with more disassembling skills could have a look at it.
