VirtualSMC — SMC Emulator

[vit9696 1,097]

SMC emulator with 2nd generation SMC support. Includes some monitoring plugins as API usage examples. New plugin additions are very welcome, given that they are well-written.

 

Source code: repository.

FAQ and documentation: link.

Features and configuration: link.

 

I wish to express my deep gratitude to all the people who worked on this project with me.

It works. Though I seem to have lost GPU sensor data in iStat, as well as some temperature readings. Is there additional configuration I need to set in order get correct SMC output for my model (iMac17,1)?

[vit9696 1,097]

Sensors are not a priority, and are mostly missing except CPU, Battery, and ambient light. Contributions are welcome.

I can't compile it with Xcode: /Users/wanderleypires/Documents/GitHub/VirtualSMC/VirtualSMC/kern_keys.cpp:10:10: 'Headers/kern_time.hpp' file not found. Sorry if it is a newbie question.

[Allan 5,177]

Very nice!!

 

Thank you @vit9696 

 

EDIT: And all the necessary info about the Battery are showing at the right way.

The only thing that I've worried about is the temp of my SSD.

I Got a KP using SMCProcessor, if i remove it, works perfect.

If you need something log to see it, please say it to me.

 

Thanks you @vit9696

Hi,

 

Probably some MSR register is not available on your CPU. To know which please provide a usual panic log (a screenshot would do too). keepsyms=1 -v debug=0x100 boot-args are your friends. If you go with a screenshot, make sure you add a kernel patch to avoid kext list printing (https://applelife.ru/posts/686953) and make sure the stack trace is clearly visible.

 

Also, use the debug binaries of both SMCProcessor and VirtualSMC and attach your compiled binaries, since there currently are no official releases to compare the offsets against.

 

Also, include the output of the following command in terminal:

sysctl machdep

Is there any guardian angel that let me join the party by dropping precompiled binaries here please?

Here.

[cecekpawon 941]

Muchas gracias @m0no 

 

Booted fine with Ozmosis. But my "Mac-F60DEB81FF30ACF6" isnt there yet, IDK if everything is corrected. I guess I need to wait for g00d contributors to fill the datas for that board-id LOL. Kudos to author!

Hi

Do we need to use efi driver+kext?

or is one of them is enough?

I don't use sensors at all

thanks

You need both.

Now the 6 million dollar question

Does this REPLACE FakeSMC??

[cecekpawon 941]

According to FAQ (thanks to Applelife), efi driver need to wotk with FileVault

Yes

[KGP-iMacPro 281]

Congrats to the authors! 

 

However, 

 

a.) seems not to properly compile under 10.14, Xcode 10 (repetitive nasm, mtoc, etc. errors discussed and already fixed along the IM Build_Clover.command thread) 

b.) Processor kext not compatible with Skylake-X (KP)

c.) No X299 onboard sensor data

d.) No ATI/Nvidia GPU Sensor data

 

below I provide a link to the latest working FakeSMC Skylake-X/X299 HWSensor distribution, in case that this helps...

Cheers,

 

KGP

Do not use HWMonitor with VirtualSMC, correct data are not guaranteed.

HWMonitor only for FakeSMC.
Use iStat Menus.

tryied the virtualsmc with smcprocessor an istat is not working properly as i do not see fans

[Wppley2 16]

Hi all! I've managed to build the kexts, but hen I install it in EFI/CLOVER/KEXTS it stuck on dependency. We have to install VirtualSMC in S/L/E?

No.

At present time there are only CPU, battery and ambient light sensors.

For frequency show, install  Intel® Power Gadget

Sorry but it stuck completly, but i whant to test. Anybody can help me?

I committed a change that is supposed to fix kernel panics with SMCProcessor.kext.

 

Regarding boot issues, I strongly recommend to read the instructions before using any software.

https://github.com/acidanthera/VirtualSMC/blob/master/Docs/FAQ.md#what-are-the-requirements

dart=0 could be related, I am still looking for a better workaround for this bug.

 

Also, regarding HWMonitor, it is not like it should not be used, but rather it needs to be updated to properly handle SMC keys according to Apple docs found in libSMC.dylib.

Some details may be found in: https://github.com/acidanthera/VirtualSMC/blob/master/Docs/SensorInfo.md#recommendations

 

UPD: Committed a change to fix hangs without dart=0 on 10.12.

HWMonitor devs, turn on your machines 

[Wppley2 16]

All working good at the moment. Thanks to the devs.

Thanks for the fix, @vit9696! Appreciated! 

 

My Skylake-X/X299 i9-7980XE (18 core)/ASUS Prime X299 Deluxe system now successfully boots without boot flag dart=0 and with all 3 sensor kexts included (no further KPs)...

 

However, still there seems to exist an issue with the sensor kext information or with the interface to iStat Menus... 

 

Let's just focus on the CPU sensor information, as there are anyway no sensor kexts yet for providing e.g. GPU and X299 onboard information:  

 

All I see under sensors.. 

 

  

 

..is the average CPU Frequency, while the "average" CPU Temp always remains 0.. There is no information about CPU cores and heatsink temps, CPU cores and package frequencies , CPU cores and package multipliers or CPU Package power consumption, when compared with @interferenc 's perfectly working FakeSMC and HWSensor kext distribution. 

 

 

Evidently, as yet there are no kexts for displaying GPU, onboard, memory or PSU properties, I am also missing information on CPU, RAM and PSU voltage and power consumption, fan rotation or GPU and mainboard temps.. 

 

Only thing currently working in iStat Menus is the delivered information on CPU thread utilisation, which is properly displayed for all 36 threads..  

 

     

 

 

although the latter also might be provided without adding any CPU sensor kext distribution.. 

 

I really hope that @interferenc's FakeSMC and HWSensor kext distribution linked in post 

 

might be of help for providing complete and correct sensor information also with your current and novel VirtualSMC distribution..
