Colin Percival 20d1a304b3 Reduce the Xen timecounter from 1GHz to 2^-9 GHz, thereby increasing the ... timecounter period from 2^32 ns (~4.3s) to 2^41 ns (~36m39s). Some time sharing systems can skip clock interrupts for a few seconds when under load (e.g., if we've recently used more than our fair share of CPU and someone else wants a burst of CPU) and we were losing time in quanta of 2^32 ns due to timecounter wrapping. Increasing the timecounter period up to 2^41 ns is definitely overkill, but we still have microsecond timecounter precision, and anyone using paravirtualized hardware when they need submicrosecond timing is crazy.		2010-12-11 22:33:33 +00:00
