Adding Radeon GPU Temperatures

[startergo]

Maybe you can incorporate these sensors: https://github.com/aluveitie/RadeonSensor

I don't mind, any chance for a sample code how to query those GPU list and T values? I don't own a hackintosh.

All you need is 2 Kexts. One of them is installed inside the other one. So install this kext in /L/E and see if you can read the temperatures of AMD GPU on a real Mac in MFC. SIP probably has to be disabled as the kexts are not signed. VirtualSMC.kext.zip

The source code for the RadeonSensorSMC.kext is in my first post. https://github.com/Andrej-Antipov/Kext-Install-Utility/blob/master/KextLEinstaller.zip

Some thoughts about this possible feature.

This is obviosly limited to

• Intel macs using Thunderbolt eGPU
• Classic Mac Pro (5,1)
• Mac Pro 2019
• Hackintosh

A custom kext is an issue here - special code signing from Apple is required.

Still not sure if it would be worth efforts.

FYI. It's reporting egpu temp without any custom kext. I don't know when it happened exactly from. but I checked this today after update to ventura.

[startergo]

Ventura shows it. But not earlier macOS.

Could you please run this command and post the output?

ioreg -l | grep '"PerformanceStatistics"' | sed -E "s/,/\\n/g;s/\"//g" | grep -E "(temp|power|Device Utilization|Fan|speed|GPU Activity)"

Radeon temperature shows now. At least on hackintosh in Ventura:

Edit: Added statistics for troubleshooting

I can confirm it's working in Ventura
