| -c cpu | Subsequent enable and disable options affect the CPU denoted by cpu. The argument cpu is either a number denoting a CPU number in the system, or the string "*", denoting all CPUs in the system. |
| -d pmc | Disable PMC number pmc on the CPU specified by -c , preventing it from being used till subsequently re-enabled. The argument pmc is either a number denoting a specified PMC, or the string "*" denoting all the PMCs on the specified CPU. Only idle PMCs may be disabled. |
| -e pmc | Enable PMC number pmc, on the CPU specified by -c , allowing it to be used in the future. The argument pmc is either a number denoting a specified PMC, or the string "*" denoting all the PMCs on the specified CPU. If PMC pmc is already enabled, this option has no effect. |
| -l | List available hardware performance counters and their current disposition. |
| -L | List available hardware performance counter classes and their supported event names. |
| -s | Print driver statistics maintained by hwpmc(4). |

EXAMPLES
To disable all PMCs on all CPUs, use the command: "pmccontrol -d*"
To enable all PMCs on all CPUs, use:
"pmccontrol -e*"
To disable PMCs 0 and 1 on CPU 2, use:
"pmccontrol -c2 -d0 -d1"
To disable PMC 0 of CPU 0 only, and enable all other PMCS on all other CPUs, use:
"pmccontrol -c* -e* -c0 -d0"
