NAME
     pmc — performance-monitoring counter interface for command execution

SYNOPSIS
     pmc -h
     pmc -C
     pmc -c event command [options ...]

DESCRIPTION
     pmc is a means of using a processor's performance-monitoring counter
     (PMC) facility to measure various aspects of a program's execution.  It
     is meant to be used in a fashion similar to time(1).

     The arguments are as follows:

     -h	     Display a list of performance counter events available on the
	     system.

     -C	     Cancel any performance counters that are currently running.

     -c event
	     Count the event specified by event while running the command.

DIAGNOSTICS
     PMC support is not compiled into the kernel  Performance-monitoring
     counter support has not been compiled into the kernel.  It may be
     included using the PERFCTRS option.  See options(4) for details.

     PMC counters are not supported by CPU  Performance-monitoring counters
     are not available for the CPU.

SEE ALSO
     time(1), options(4)

HISTORY
     The pmc command first appeared in NetBSD 1.6.

AUTHORS
     The pmc command was written by Frank van der Linden
     ⟨fvdl@wasabisystems.com⟩.	The kernel support for reading performance
     counters on the i386 architecture was written by
     Jason R. Thorpe ⟨thorpej@zembu.com⟩.

BUGS
     The pmc command currently only supports performance-monitoring counters
     on the i386 architecture.
