`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).
