+ANRdaemon is a daemon to help analyze ANR due to CPU starvation by logging system
+activity when CPU usage is very high. The daemon uses debugfs underlying for
+logging. Trace are configured ahead by setting different modules in /d/tracing.
+Depending on the CPU usage level, the trace is turn on/off by writting to the
+global control /d/trace/trace_on. The raw trace file is stored at
+/d/tracing/trace.
+
+The daemon will be started at boot time and will be running with the following
+settings:
+$ ANRdaemon -t 9990 sched gfx am
+This means tracing will be enabled above 99.90% CPU utilization and will trace
+sched, gfx and am modules (See -h for more info).
+
+Use ANRdaemon_get_trace.sh [device serial] to dump and fetch the compressed trace file.
+
+The compressed trace file can be parsed using systrace:
+$ systrace.py --from-file=<path to compressed trace file>
+
+Known issue: in the systrace output, anrdaemon will show up when the trace is
+not running. This is because the daemon process turns off tracing when CPU usage
+drops, the last entry it leaves in the raw trace file is the scheduler switched
+from some other process to the daemon. Then sometime later (say 20 secs later),
+when the CPU usage becomes high and the daemon process turn on tracing again,
+the first entry in /d/tracing/trace logged by sched is switching away from the
+daemon process to some other process. Due to this artifact, when the raw trace
+file is parsed by systrace.py, the daemon process is shown as running for the
+whole 20secs (because from systrace's view, the two 20 sec apart sched trace
+entries regarding the daemon process indicates the daemon process ran continuously
+for all 20sec). However, this will not affect the actual captured trace during
+high CPU usage case.

- * Binder add integers benchmark
+ * Binder add integers benchmark (Using google-benchmark library)

- * Measures the rate at which a short binder IPC operation can be

- * that contains two integers. For each parcel that the server
- * receives, it adds the two integers and sends the sum back to
- * the client.
- *
- * This benchmark supports the following command-line options:
- *
- * -c cpu - bind client to specified cpu (default: unbound)
- * -s cpu - bind server to specified cpu (default: unbound)
- * -n num - perform IPC operation num times (default: 1000)
- * -d time - delay specified amount of seconds after each
- * IPC operation. (default 1e-3)

+# 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
