H A D | builtin-top.c | 42e59d7d Tue Oct 06 08:14:21 CDT 2009 Ingo Molnar <mingo@elte.hu> perf tools: Default to 1 KHz auto-sampling freq events
Use auto-freq events by default in perf record and perf top.
This allows more consistent hardware event sampling, regardless of the intensity of the underlying event.
It also keeps us from over-sampling on larger/busier systems.
(also make surrounding initializations more consistent)
