NetBSD 6.1.5 - man page for pmc (netbsd section 1)

PMC(1)				   BSD General Commands Manual				   PMC(1)

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 mea-
     sure 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 archi-
     tecture.
