Sorry for reposting it.
For example, 1 rdtsc() is invoked on CPU0 2 process is migrated to CPU1, and rdtsc() is invoked on CPU1 3 if TSC on CPU1 is slower than TSC on CPU0, can kernel guarantee that the second rdtsc() doesn't return a value smaller than the one returned by the first rdtsc()?
Thanks, Forrest
