38 # Description: A program to run a simple program against every available
39 # pmc counter present in a system.
43 # pmctest.py -p ls > /dev/null
45 # This should result in ls being run with every available counter
46 # and the system should neither lock up nor panic.
48 # The default is to wait after each counter is tested. Since the
49 # prompt would go to stdout you won't see it, just press return
50 # to continue or Ctrl-D to stop.
