CPU temperature in iStat

If someone want to, please test this. Should show temp for each core, and there's a "tjmax" key in Info.plist so one can change it's value.

Thanks.

Hi,

Checked the latest edit to your fakesmc.kext. Indeed shows 4 CPU temp values in istat menus. Left Tjmax @ 100 (default), which values seem correct with Q9550 CPU.

But friend, those messages about smckeys are still there in the log. All else seems to work okay.

 

Thank you.

Mate those are there with a purpose, the kext is not finished...

Wait until someone add debug option in plist, or you do the job if that upset you so much...

Temperature monitor still shows 9000 degrees for diode A with this one. Anyone care to confirm?

I confirm it, but if you change the kext to work with Temperature Monitor, iStat won't work anymore.

Temperature Monitor reads the same 2 bytes TC0D key, but big-endian, while iStat uses little-endian.

For example:

TC0D =

iStat reads: 0x0031 = 49

Temperature Monitor reads 0x3100 = 12544

I confirm it, but if you change the kext to work with Temperature Monitor, iStat won't work anymore.

 

I get these kind of readings, Temperature monitor application works, but all sensors show +5 degrees compared to VoodooMonitor or iStat.

Maybe Temperature Monitor calculates a different Tjmax value for your CPU?

Here it shows the same values as iStat and VoodooMonitor (except for diode temps which are 10000º+ as mentioned).

 

In Temperature Monitor preferences, under sensor tab, you can select "don't acquire readings from this sensor" for the ones showing wrong values.

Seems to be defined to 105 for some reason.

I tried it, but im just getting Sensor A and B for my Quad Core Q6600 in iStat, Temp monitor reprts A B C D but as youve explained the wrong temp 8000+

Strange thing, just tested with CPU injector and it still shows 4 cores, did you test without it to see if it's the problem?

Do you see 4 CPUs in IORegistryExplorer?

 

Edit: did you check iStat preferences? Maybe other cores are unchecked. If Temperature Monitor shows the other cores, the keys must be there (even it showing wrong values).

i see this:

 

please test with this kext

fakesmc.kext.zip

then check your kernel.log for which keys were added

 

grep added /var/log/kernel.log

 

Oct 22 15:40:18 localhost kernel[0]: added TC0D key

Oct 22 15:40:18 localhost kernel[0]: added TC1D key

Oct 22 15:40:18 localhost kernel[0]: added TC2D key

Oct 22 15:40:18 localhost kernel[0]: added TC3D key

ok tried new kext get these messages

Oct 22 19:47:25 localhost kernel[0]: netkas presents fakesmc, a kext which emulates smc device

Oct 22 19:47:25 localhost kernel[0]: added TC0D key

Oct 22 19:47:25 localhost kernel[0]: added TC1D key

Oct 22 19:47:25 localhost kernel[0]: added TC2D key

Oct 22 19:47:25 localhost kernel[0]: added TC3D key

 

and some key not found...

 

Still 2 CPU A and B in iStat and the IORegistryExplorer shows the same information as before.

Oct 22 19:47:25 localhost kernel[0]: added TC2D key

Oct 22 19:47:25 localhost kernel[0]: added TC3D key

 

This means the keys for all cores were added, the problem must be in iStat.

Are you using the latest version? Try to reinstall version 2.0 and the sensor module.

iStatPro that works in Dashboard uses following keys for sensors

I've updated latest version to use with markswell's utulities. Now it works well in snowleo and shows correctly all cores.

Thank you Mojodojo.

 

I see you use cpuid_count_cores() from cpuid.h, the previous method didn't work for you in SnowLeo? Should we increase MaxCpuCount then?

 

BTW, are you the author of VoodooMonitor (CPU-i)? I got the code to count cores from CPU-i 1.03 source.

 

Are markswell's utilities open source? It would be nice to add mobo temp and fan speeds to fakesmc, I see it supports some more chips now.

 

Regards.

Yes, I made cpu-i.

 

You must ask a question about license and mark-i sources to mark. Cpuid utilities from voodoomonitor is different from mark-i project.

 

It would be great if fakesmc will receive mark-i functionality.
