Hi Harald,

Good to hear :-)

Do you have any answers to my previous questions:

1) My driver uses the CPUID instruction to read the performance
registers that contain the temp and voltage data. Harald's driver
reads MSRs. I don't know if there are any benefits of using one method
over the other.

2) If we pick Harald's, it would be nice if his driver can also read
and export the CPU core voltage.

3) Quite a few testers of my driver reported 0 temp readings for some
C7 CPUs. I was never able to figure out why some CPUs return 0 temp
but I'm guessing it depends on the thermal monitor settings. I'd like
to understand what is going on and hope Harald can shed some light.
