| 1`perfmon' is a sample program to access the performance-monitoring 2counters on Pentium and Pentium Pro CPUs. See perfmon(4) for a 3description of this facility. 4 5The program takes the following options: 6 7 -u count events in user mode 8 -o count events in kernel mode --- 4 unchanged lines hidden (view full) --- 13 -s n sleep `n' seconds between loop iterations (default 0) 14 15The following options are not implemented on Pentium CPUs: 16 17 -m n use count mask `n' 18 -i invert sense of count mask comparison 19 -U n use unit mask `n' 20 | 1`perfmon' is a sample program to access the performance-monitoring 2counters on Pentium and Pentium Pro CPUs.
