Support

After the latest kernel update to 5.10.19-1 k10temp is missing some sensors, before it showed:

$ sensors
 k10temp-pci-00c3
 Adapter: PCI adapter
 Vcore:         1.41 V  
 Vsoc:          1.13 V  
 Icore:        33.00 A  
 Isoc:         10.75 A
 Tctl:         +43.0°C  
 Tdie:         +43.0°C

After the update it only shows Tctl and Tdie.

Please fix it, thank you.

what was the last working kernel for you out of 5.10 series?

They dropped those sensors in k10temp.

Seems it now also got backported to 5.10. :man_shrugging:

edit

Seems that happened with revision 4 already:
