Actually, on ARM the default HZ is 100, not 1000 ... so the default latency would be 10 msec not 1 msec. Recent kernels have oneshot clockevent support for PXA though, so there are many options. I don't recall whether HZ is settable there, but high-res timers might affect scheduling a bit. - Dave ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
