Hi Peter,
Thank you for looking at this patchset.
Yes, I am certain it is 0 or near 0 on reset on this machine. Because,
I actually wondered about it, and used stop watch as an alternative way
to verify the result, twice.
While, I suspect it is often the case that on reset tsc is 0, it is not
really import, as the offset value is not the important part of the
project. The important part is that we can cover the whole Linux boot
process with timestamps, and know where spend time, and avoid
regressions in the future.
Thank you,
Pasha

Lol, how cute. You assume TSC starts at 0 on reset.
