Hi,
analysing the watchdog characteristics in our scenarios, I just wondered
if it is SMP-aware (we have no SMP in use, it's a pure analytical concern).
The watchdog timeout is stored system-wide in nkpod->watchdog_trigger,
but it is based on a per-CPU clock (TSC). Is the tick IRQ bound to a
specific CPU in SMP scenarios so that this doesn't matter? Or am I just
overseeing some detail?
Jan
