# Description: A program to run a simple program against every available
# pmc counter present in a system.
#
# To use:
#
# pmctest.py -p ls > /dev/null
#
# This should result in ls being run with every available counter
# and the system should neither lock up nor panic.
#
# The default is to wait after each counter is tested. Since the
# prompt would go to stdout you won't see it, just press return
# to continue or Ctrl-D to stop.
import sys
import subprocess
from subprocess import PIPE
# A list of strings that are not really counters, just
# name tags that are output by pmccontrol -L
