This is a slightly modified FakeSMC kext, I just added the temp keys and some lines of code from VoodooMonitor to update them, so iStat will show the CPU core temps. It was tested on Snow Leopard and Leopard.

Thanks goes to Master Chief for his help, Netkas for the help and for writing FakeSMC, Mozodojo for writing VoodooMonitor, and Superhai for writing VoodooPower.

23/10/2009 - Updated by Mozodojo to use Markswell's utilities (uses code from Mac OS X kernel). Now it works well in Snow Leopard and shows correctly all cores.

20/11/2009 - Netkas added this patch to FakeSMC 2.5, he reworked it for reading temps on demand, not in loop.
Download from http://netkas.org/?p=338

23/05/2010 - Mozodojo, Slice and Usr-sse2 added plugin support to FakeSMC (fan, voltage, GPU, mobo sensors, ...)

14/10/2010 - Mozodojo released a new version that works from Extra folder.

Thanks man.  I'll look into it after the break.

Edit: See here:  keysToAdd = OSDynamicCast(OSDictionary, getProperty("SMCKeys"));

You don't need to re-compile the source – you can simply add a dictionary key (SMCKeys) in the Info.plist (when that is missing as child of FakeSMC) and add your key TCOD (type: Data) there.

Ok, but doing this way won't the key have a static value? It has to be updated with CPU temperature.

I did it and it works.  Real CPU temps, not just a static value.  Give it a try.

What about adding fan speeds and mobo temps?

But did you use the version I uploaded, or your original fakesmc?

With original fakesmc, if I add the key to Info.plist, iStat shows the static value. What value did you add? Just the key, without value?

About fan speeds and mobo temps, I think they must be get from the sensor chip, like Mark-i does from Winbond. Would have to take a look at lm-sensors from Linux.

I'll attach it shortly (attachment removed/see post#20).  Busy working on my Mac right now.

I haven't really check, but where is the CPU temp coming from then?

p.s. It's not a ZIP file but the kext I am using right now (didn't had time to compress it first).

Maybe you are using the version I modified, or you have some code in DSDT, or some kext loaded that does the magic. I tried just adding the key to Info.plist and it didn't work.

The code I added (from VoodooMonitor) is:
		UInt8 mynewvalue = 0;
		UInt64 msr = rdmsr64(0x019C);
		if (msr & 0x80000000) mynewvalue = (msr >> 16) & 0x7F;
		SMCData MySMCKey = 0;
		MySMCKey = SMCDevice->FindSMCKey("TC0D");
		MySMCKey->data[0] = 100-mynewvalue;
Probably "100" in the last line should be replaced by calculated Tjmax value.
This is the diode temperature.
Mark-i shows temp from the sensor under the CPU, which comes from Winbond chip, like mobo temp and fan speed (I think).

That is weird.  Did you patch your DSDT with the SMBUS/EC code blocks I've added?  And please add a kextstat dump for me.
BTW: You are running in 32 bit mode, right?

Yeah I noticed the new lines.  I'll better wait for your answers and attachments first (saving me some time).

No, I didn't add the SMBUS/EC patch to DSDT, I'll try to do it to see if it makes the difference.

I'm running 64 bit mode.

Something tells me that having a working/functional SBUS/EC is mighty important ;)

I feel mysteriously compelled to add the EC now, I only did the SBUS...I'm getting the same error from fakesmc after waking up from sleep.

/EDIT

Done... http://www.insanelym...40#entry1299409

I see "FakeSMC: key info not found CLWK, length - 6" when waking up from S3 sleep with the fakeSMC.kext from this thread.

I do see those FakeSMC messages in kernel.log, I guess they are the keys that iStat tries to read.

I added the SMBUS/EC patch to DSDT, copied all code blocks with EC support and SBUS support comments. The only difference is that my DSDT doesn't have an LPCB device, so I put the code from it in SBRG, which has the same address.

kextstat after SMBUS/EC patch to DSDT:

After that I added the "TC0D" key to Info.plist (original FakeSMC) and iStat still shows "0º C" for CPU temp.

Could you do the test? Use original fakesmc.kext from netkas and add TC0D key to Info.plist.

Thanks for your help.

I do see those FakeSMC messages in kernel.log, I guess they are the keys that iStat tries to read.

I added the SMBUS/EC patch to DSDT, copied all code blocks with EC support and SBUS support comments. The only difference is that my DSDT doesn't have an LPCB device, so I put the code from it in SBRG, which has the same address.

kextstat after SMBUS/EC patch to DSDT:

Would you mind attaching yours?  The one showing 0?  At least then we know for sure that we use the same version.

Sure, here it is
removed, doesn't work

The one attached to the first post also has TC0D in Info.plist, but shows variable temp because it has the code from VoodooMonitor.

Could be a condition in applesmc_fill_data?

What do you recommend, this or use LoopTimerEvent?

Thanks for your attention.

No temps with this version.  Just a dash "-" and nothing else.

Maybe Netkas can explain why we need fakesmc.kext in the first place, because the kext uses the very same ports.  What's the catch here?

BTW: I no longer use fakesmc.kext nor any other related kext (never mind asking how because I won't get sacked over this – my employer has a good relationship with Apple).

Does iStat show CPU temp without fakesmc.kext?

Edit: just tried to boot without fakesmc and boot stops before starting the GUI, I guess it's waiting for DSMOS. Did you add some DSDT code to be able to boot without fakesmc?

Not without hacking the DSDT first no.

You cannot boot without fakesmc.kext no.  I can because I did something "extra" which I won't reveal or I'll end up in court one day.  Think about it what you want, but this is as far as it goes (I have a family to take care off).

Asus mobo owners like us are very lucky to have Asus probe code in our DSDT .  This basically means that everything we need (CPU/Case/MB temperatures, fan speeds, voltage, bus speed et all) is available in our DSDT.

No problem man, I respect your reasons.

I'll move the temp update code from LoopTimerEvent to applesmc_fill_data as netkas suggested. iStat reads it from SMC each 10 seconds by default, so no need to update it every second, this way it will be updated when it's read.

For now this is good to me, I'll edit the first post so if someone is looking for this, won't have to read all posts.

If you don't mind, please remove the attachment from post #6, it has the update code in LoopTimerEvent, updates once a second.

Thanks again for your help.
