`perfmon' is a sample program to access the performance-monitoring
counters on Pentium and Pentium Pro CPUs. See perfmon(4) for a
description of this facility.
The program takes the following options:
-u count events in user mode
-o count events in kernel mode
(these two can be combined)
-e count events, not duration
-l n run `n' loops (default 50)
-s n sleep `n' seconds between loop iterations (default 0)
The following options are not implemented on Pentium CPUs:
-m n use count mask `n'
-i invert sense of count mask comparison
-U n use unit mask `n'
There is one mandatory argument, which must be the number of the counter.
All numbers can be specified in any format acceptable to strtol(3).
