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