I changed the P-States as directed, but still no stepping.

 

I've attached my merged DSDT to see if anyone here can help me figure out what I'm missing.

 

Thanks for all the help thus far.

MacPro2,1

 

Then you need to ammend the ACPI_SMC_PlatformPlugin.kext info.plist with MacPro2,1, as described earlier in the thread.

Your CPU cores are labeled CPU1,2,3,4

They should be CPU0, 1, 2, 3 no?

 

also make the edit to ACPI_SMC_PlatformPlugin.kext info.plist if not done already.

Ah, that is more like it (the one in your PM was garbled).

 

Now, don't you worry about the CPUn identifier, which is fine (Asus just doesn't like calling the first CPU 0). However, I do see that you have two cores (see NCPU) yet you included 4 Processor declarations! Please remove the last two. One other thing is that the _CST object is still missing, and then this coding style:

Return (^^CPU1._PSS ())
Return (^^CPU1._PPC)

Which I personally would replace by:

Return (\_PR.CPU1._PSS())

Just to make things more logical. And when you include _CST then don't forget to call it from the second CPU like this:

Return (\_PR.CPU1._CST ())

Also replace the two PDC0's with TYPE in your _CST object (to match your DSDT).

Now I don't have any CST code available from my dumps, so I'm still a little fuzzy on how to use the CST code from another machine (like the MacPro3,1 for example) and make it work. I've tried a simple append to my current DSDT and I still see no evidence of stepping or use of the C-state code. Is there a site with example code, or a manual I can read?

You are using Snow Leopard, correct (sig might be wrong)?

What model identifier do you see in System Profiler?

Does that match with any of the models in the ACPI_SMC_PlatformPlugin.kext info.plist?

Where and how did you add _CST()

 

p.s. The first post has some links (me ducks).

Thanks :P

 

What entries in the plist do I need to change?

if I use smbios.plist with IMac9,1 (for example) do I still need to edit this plist?

(because MacPro2,1 isn't in the plis but IMac9,1 is)

See post #15 for Leo and #53 for SL

As Chief told you - Enter the model that's shown in System Profiler.

Hello & Thanks for the interest. I have not used any unmodified DSDT. There is only one patched DSDT.aml which I use on the 10.5.7 version (working fully) and same DSDT on a separate spare HDD (in same machine) with 10.6 install to test.

In 10.5.7 AppleIntelCPU...kext initializes properly but same DSDT in 10.6 causes KP with AppleIntelCPU...kext. Can you beat that?

DSDT.aml Attached here. Please take a peek.

 

Exactly!

 

BTW: The version of CPU-i that I compiled for Snow Leopard (32-bit) works here – unlike that ugly MSRTools tools thing. Even for my computer, which still shows up as: "P5K PRO" in System Profiler (I changed the ACPI plugin Info.plist). And not only that. because the 7.5 multiplier (0x4720 in my _PSS) works too!!! I am however still looking for the value for the 6.5 multiplier; the reported value in CPU-i (0x461C) doesn't seem to work here (no 6.5 showing up in CPU-i).

 

 

I take it that the unmodified dsdt.dsl works with Snow Leopard? As in it fails after your changed it? Then attach both the original (working) and modified dsdt.dsl because how else should anyone here help you?

 

 

What kind of "Model Identifier:" do you see in System Profiler?

 

Mine still reports: "P5K PRO" and thus I modified ACPI_SMC_PlatformPlugin.kext (I simply replaced MacPro3,1" and "MacPro4,1" with "P5K PRO" in the Info.plist) to get P-stepping working.

Yep, I'm using SL. I've set my model to MacPro3,1, so I shouldn't have to modify the ACPI_SMC_PlatformPlugin plist, right?

 

Here is how I've added the CST object, does that appear correct to you?

Yep, I'm using SL. I've set my model to MacPro3,1, so I shouldn't have to modify the ACPI_SMC_PlatformPlugin plist, right?

 

You still need to make the edit . I'm set to MacPro3,1 also and had to do this.

 

##EDit## CST looks fine but as I said in an earlyer post the MacPro3,1 only has arguments for C1 and C2.

See if you can get this working and I'll post the _cst I have with C1, C2 and C3 when I get bacik from work this evening.

;) it's a fiddly isn't it ..

NB edit above ^^^

 

 

##ALSO## still to be proved - if MacPro only has C1 and C2 - and we set model to MacPro in ACPI_SMC, will C3 be supported ??

Well I can't test until tonight now, but I'll be sure and report back ASAP. I'm getting excited now. :D

Thanks! CPU-I is working and showing that Speedstepping is working :D CPU-I is showing the lowest p-state under "status" (x6 multiplier). Strange thing is, it doesn't update once i have high cpu load. Is that normal? It should be showing x7 or even x8 once CPU gets hit.

 

Without any SSDT-Editing i have the same results in CPU-i as you.

But here it seems to report correct temp and frequency, though changes only happen x6 to x8 and viceversa.

Here is how I've added the CST object, does that appear correct to you?

...

I've attached the full file below.

I wonder why you have all the extra bits (NPCT, SPCT, XPSS, PCT, PPC, SPSS and PSD) in it. I mean you normally only need the objects: PDC, OSC and CST because the former will be read from SystemMemory (see OperationRegion). Sure, you need to add PSS to change/enhance the P-Stepping, but that's about it.

 

Without any SSDT-Editing i have the same results in CPU-i as you.

But here it seems to report correct temp and frequency, though changes only happen x6 to x8 and viceversa.

I wonder what multipliers you and ApexDE are using.

 

N.b. Please note that this might be caused by incorrectly specified power values (second argument) in your PSS object.

 

TIP: You might want to check your system.log on Leopard or kernel.log on Snow Leopard; look for CPU-i buffer related errors!

@formerlyknownas Great thread, but is there another app besides p-state calculator that will allow fractional multipliers? The Q9550 has six p-states. with multipliers of 6, 6.5, 7, 7.5, 8 and 8.5.

 

Without any editing of the dsdt and with nullcpupm in my extra folder CPU-i is showing a change from 6x at idle to 8.5 under load. The multiplier/freq is changing but the voltage always remains at the highest p-state.

 

@william parker

I am just delving into the speedstep myself. Also with the Q9550 processor. Since p-state setting are processor dependent... Please keep posted if you make any progress.

Seems like bit 14 (0x4000/16384) is set for all fractional multipliers i.e. add a 4 in front of the values supplied by the P-States Calculator (0x4720 is working here for 7.5).

 

Update: I checked the source code of CPU-i and that appears to be correct. Have a look:

#define FID(ctl) (((ctl) & 0xff00) >> 8)
#define VID(ctl) ((ctl) & 0x00ff)

columnIdentifier = [NSString stringWithFormat:@"x %d%s", fid & 0x1F, fid & 0x40 ? ".5" : ".0" ];

PStatesArray[i].Multiplier =  (fid & 0x0f) + (fid & 0x1F, fid & 0x40 ? 0.5 : 0.0);

But the error checking is... well there is none so I don't know what the API returns.

Hello,

 

Help is needed here :P

 

I followed FormerlyKnownAs's guide at the first post, It took me quite some time and I'm not sure I know exactly what to add to my DSDT, so I have a few questions that will help me clarify things a bit:

 

  1. I used ubuntu to dump my ssdt tables, and I got 3 ssdt files, 2xcpuist and 1xcpupm, I guess i do not have c-states ?
     
  2. I read the guide for combining the ssdt's into the dsdt at http://s2.enemy.org/~zaunmayc/speedstep8.04.html How far do i have to go along with the guide ? do i just need to stop after cat'ing the ssdt's to the dsdt ? The guy over there says something about setting the correct register adress for the PERF_CTL and the PERF_STATUS registers, do I have to do that ?
     
  3. I opened FormerlyKnownAs's combined dsdt file and tried to match the end of the file to my own ssdt's, I saw that on FormerlyKnownAs's dsdt there was this code:
     
            Method (_PCT, 0, NotSerialized)
           {
               If (LEqual (And (CFGD, 0x00060000), 0x00020000))
               {
                   Return (Package (0x02)
                   {
                       ResourceTemplate ()
                       {
                           Register (SystemIO, 
                               0x10,               // Bit Width
                               0x00,               // Bit Offset
                               0x0000000000000199, // Address
                               ,)
                       }, 
    
                       ResourceTemplate ()
                       {
                           Register (SystemIO, 
                               0x10,               // Bit Width
                               0x00,               // Bit Offset
                               0x0000000000000198, // Address
                               ,)
                       }
                   })
               }


     
    on my ssdt there was this code:
     

            Method (_PCT, 0, NotSerialized)
           {
               If (LEqual (And (CFGD, 0x00060000), 0x00020000))
               {
                   Return (Package (0x02)
                   {
                       ResourceTemplate ()
                       {
                           Register (SystemIO, 
                               0x10,               // Bit Width
                               0x00,               // Bit Offset
                               0x0000000000000880, // Address
                               ,)
                       }, 
    
                       ResourceTemplate ()
                       {
                           Register (SystemIO, 
                               0x10,               // Bit Width
                               0x00,               // Bit Offset
                               0x0000000000000882, // Address
                               ,)
                       }
                   })
               }


     
    Why there's a difference between the addresses of the two ? do I have to change mine to 199 and 198 like on FormerlyKnownAs's dsdt ? or do I need to leave it as it is as long as it's not 000000 ? is that what the guy meant by fixing the PERF_CTL and the PERF_STATUS registers ?
     

  4. By looking on FormerlyKnownAs's DSDT it looks like the CST section from the Mac Pro is inserted before the CPUIST code inside the SCOPE (_PR.CPU0), is that correct ?
     
  5. Is there anywhere an official info by intel on the speed steps for each of it's cpu's ? If not, does anyone know what info should be inserted to the PSS for Intel C2D E8400 (3GHz) ? currently I have only 2 steps on the ACPI.

 

10x anyone in advance,

Jonathan

Here's DSDT with C1, 2 and 3 for my MB that does not support C-states

DSDT11_09_09.dsl.zip

 

Note: I've tried with cst memory address left as zero and with (as posted) arbitrary consecutive addresses. Maybe these addresses are already occupied for this Gigabyte MB?? suggestions welcome.

 

and here is dmesg having booted with voodoo kernel (NB voodoo kernel does not like fakeSMC !!)

Note I get same result with memory addresses set to 0 and arbitrary!

Current conclusion - If it is possible to fix ACPI for MB that do not support C-states, I'm not smart enough to do it!

Here's DSDT with C1, 2 and 3 for my MB that does not support C-states

Current conclusion - If it is possible to fix ACPI for MB that do not support C-states, I'm not smart enough to do it!

Huh? I am confused. You mean that this CST object �" the one in the attachment file �" wasn't obtained from your BIOS? Or are you saying that it doesn't work for you? Anyway. Let's just have a look at some part of your dsdt.dsl:

    Scope (_PR.CPU0)
   {
       Name (HI0, Zero)
       Name (HC0, Zero)
       Name (TLD0, Zero)
       Method (_PDC, 1, NotSerialized)
       {
           CreateDWordField (Arg0, 0x08, CAP0)
           Store (CAP0, PDC0)
           If (LEqual (TLD0, Zero)) // Is TLD0 Zero?  Which is true.
           {
               If (LEqual (And (PDC0, 0x0A), 0x0A)) // Is bit 2 of PDC0 set?  Which must be true, or it won't load the IST table.
               {
                   If (And (CFGD, 0x02)) // Is bit 1 of CFGD set?  Which is true for the provided value of 0x04030302.
                   {
                       // Point IST0 to the provided memory area
                       OperationRegion (IST0, SystemMemory, DerefOf (Index (SSDT, One)), DerefOf (Index (SSDT, 0x02
                           )))
                       Load (IST0, HI0) // Load the IST0 table �" HI0 is a handle which can be used to unload the table.
                   }

                   Store (One, TLD0) // Preserve state information across S1-S3 sleep.
               }
           }
       }
   }

And in particular the following snippet, which is part of all but the first PDC object:

			  
If (And (CFGD, 0x10)) // Is bit 4 of CFGD set? Which is NOT true for the provided value of 0x04030302.
{
  OperationRegion (CSTn, SystemMemory, DerefOf (Index (SSDT, 0x0A)), DerefOf (Index (SSDT, 0x0B)))
  Load (CSTn, HC1) // Load the CSTn table.
}

This code is responsible for loading the CST tables, on MB's with CST tables that is. Now note the CFGD value in your DSDT, which is 0x4030302. Got it? Yes, that bit is not set. You might want to change it to 0x4030312 and remove the CST object from your DSDT. That should (also) work, or at least make it the same :)

 

Note that the PDC object is evaluated only once, and prior to evaluation of any other processor power management objects returning configuration information. And PDC objects are normally called with three arguments, being: RevisionID, Count and CapabilitiesDWORD1. However, not in your case it seems. Time for me to change my PDC object to see what I am getting :)

I've tried changing CFGD value to 0x4030312 and I still dont see any cst loaded in dmesg.

In fact if you look at previous output from dmesg there is no ist loaded either???? OR in fact any SSDT !!

And yes I have no cst table and have borrowed from, initially MacPro3,1 and now from HP530 but have edited C-state values to suit my latency requirements.

 

I'm stepping away from this for a week or so. Be interesting to see where you get to. I'm still sceptical that it is possible to achive c-state support if it is not native to your MB.

 

Enjoy

D.

 

**EDIT** please not with DSDT11-09-09.dsl (post No.120) and with CFGD value set to 0x4030312, my p-states are still working and I still don't have any cst evaluation errors !!

Dave,

 

I would say because of this: "PDC objects are normally called with three arguments, being: RevisionID, Count and CapabilitiesDWORD1." I mean, just have a look at the original MacPro3,1 files and note the three arguments there. Not to mention the missing OSC objects in your DSDT.

I wonder if it still works when you restore the original kext – the one without any modifications – and/or remove the (calls to) PSS object in your DSDT. If that still works... then it must be the native Intel SpeedStep Technology kicking in.

Ok, so I tested the DSDT I attached earlier with the P-states and the C-state object added and I dont' see any evidence of stepping and I'm getting garbled playback in iTunes unless I'm moving the mouse around like a mad-man.

 

Where do I set the C-state latency values in the CST object with the ones dumped in my FACP table?

Hellooo ?

 

Could someone help with the following question ?

 

Yesterday i fixed my hpet on the dsdt to use the cpupm kext, then i've seen what you guys are talking about with the _cst error. later on I found in my bios that there are options to enable c2,c3,c4 and maybe c5 states, so I enabled it, and there was no cst error on boot. I did not alter my dsdt in any other way nor made any change to the SMC plugin, does it mean that my system now works with c-states ? Do I have to do anything else ? I did notice with cpu-i that my system is now on full power (multiplier is on x9) before the change I had 2 steps out of the box x6 and x9 and most of the time was x6.

Do I have to do anything else in order to bring speed stepping back to operation ? do i still need to add the PSS to my DSDT ?

 

10x in advance,

Jonathan
