@leroyj We already know that our k10temp module doesn't have support beyond Zen 2, and needs to be updated. That's not incredibly complex, but still needs to be done. I was wondering if the amd cpu temp be probed the way you did for the intel cpu. No, AMD temperature infos are not exposed through MSR but through PCIe/MMIO (through various subsystems, like "SMU" and other ones). Like what does https://github.com/torvalds/linux/blob/master/drivers/hwmon/k10temp.c or https://github.com/ocerman/zenpower. (regarding the AI draft, there is no documented MSR 0xc0010292 in neither APM nor public Zen3 PPM) That doesn't require any specific Xen support aside the right Linux drivers in Dom0.
