TSC in oprofile

[Yaoping R. <yr...@cs...>]

Hello,

I've been using GLOBAL_POWER_EVENTS in oprofile to measure elapsed
cycles. If I understand corrently, this is different from the "elapsed
machine cycles", from the Time Stamp Counter (TSC), right? My question
is how I can get TSC with oprofile. Does oprofile support it? or I need
to read the register by myself?

Thanks a lot
