# Script to gather perf and perf/watt data for several workloads
#
# Setup:
#
# - device connected to monsoon with USB passthrough enabled
# - network enabled (baseline will be measured and subtracted
#   from results) (network needed for chrome, youtube tests)
# - the device is rebooted after each test (can be inhibited
#   with "-r 0")
#
# Default behavior is to run each of the known workloads for
# 30 minutes gathering both performance and power data.
#
# The default time can be overridden with the -t option. To
# change individual test times, a config file can be specifed
# via -f with times for individual tests. Example file contents:
#
#	idleTime=60
#	recentflingTime=60
#	chromeTime=60
#	youtubeTime=0
#	sysappsTime=60
#	suntempleTime=5
#
# Output goes to the current directory.
#
# Examples:
#
# - Run all tests for 15 minutes (default is 30): ./pwrtest.sh -t 15 -R MDA20
#
# - Use a config file for test times: ./pwrtest.sh -f ./myconfig -R MDA20
#
# - Use a init file to setup device tuneables after each restart (this is
#   a bash script which should include adb commands to set up device):
#     ./pwrtest.sh -F devtunables
#
