NAME    [Toc]    [Back]

     pctr - display CPU performance counters

SYNOPSIS    [Toc]    [Back]

     pctr [-l 5 | 6]

DESCRIPTION    [Toc]    [Back]

     The pctr program is a sample implementation of how to access
the pctr(4)
     pseudo device available on many i386 compatible machines.

     By  default, the pctr command displays the current values of
the TSC and
     any vendor specific counter registers.

     The options are as follows:

     -l 5 | 6
             List all possible vendor specific counters.  The argument specifies
 which ``family'' to display; it defaults to the
             designation of the current processor.

     The pctr program exits with a value of 0 on success or 1  on

SEE ALSO    [Toc]    [Back]


HISTORY    [Toc]    [Back]

     The pctr program appeared in OpenBSD 2.0.

BUGS    [Toc]    [Back]

     The pctr program is still orientated towards Intel brand microprocessors.
