Is the IA32_TSC_AUX_MSR initialized by the operating system per core?

which OS ?
some may not even touch MSR C000_0103h and keep its BIOS setting.

But Yes, if the OS is at all aware of hardware features then it may initialize TSCs different for each core.

Welcome back!

Thanks.
it took a horde of physicians several months to partly repair me :)
I'm now part of a machine, mobile like Darth, not like Steven (RIP).

next step will be to get new glasses or 2nd-hand eyes ...
then I may be fit again for decoding your hex dumps.
