Arm11 clock

Note: This was originally posted on 13th October 2008 at http://forums.arm.com

Hello,

Does anyone know if there is a timestamp clock in Arm? Something like the RDTSC in intel?
Or some other high frequency clock?
I need a clock to mesure performance of my linux kernel (and I use the RTC for something else).

Thanks everyone!

Thanks for the info. We know that linux isn't perfect for hard real time, but we would like to test it and see maybe it will be good enough for us.

What do you think is the best way to measure the latecy of the interrupt?

Thanks,
