# Description: A program to run a simple program against every available
|
||
|
|
# pmc counter present in a system.
|
||
|
|
#
|
||
|
|
# To use:
|
||
|
|
#
|
||
|
|
# pmctest.py ls > /dev/null
|
||
|
|
#
|
||
|
|
# This should result in ls being run with every available counter
|
||
|
|
# and the system should neither lock up nor panic.
