Can anyone here tell me where the IA32_TSC_AUX_MSR of each hw-thread register is set?
Is it set by the operating system?

Thanks in advance.

Linux has supported this MSR since it was first introduced at least 10 years ago....   I don't know if the code that sets the values is in the same place from generation to generation, but I have not run across incorrect values in the MSR....
