perf stat: Continue even on counter creation error
Before: $ perf stat ~/hackbench 5 error: syscall returned with -1 (No such device) After: $ perf stat ~/hackbench 5 Time: 1.640 Performance counter stats for '/home/mingo/hackbench 5': 6524.570382 task-clock-ticks # 3.838 CPU utilization factor 35704 context-switches # 0.005 M/sec 191 CPU-migrations # 0.000 M/sec 8958 page-faults # 0.001 M/sec <not counted> cycles <not counted> instructions <not counted> cache-references <not counted> cache-misses Wall-clock time elapsed: 1699.999995 msecs Also add -v (--verbose) option to allow the printing of failed counter opens. Plus dont print 'inf' if wall-time is zero (due to jiffies granularity), instead skip the printing of the CPU utilization factor.
