With the perf instrument configured as:
perf:
perf_type: simpleperf
command: stat
optionstring: '-a --interval-only-values --csv'
WA fails to parse simpleperf's output:

ERROR ValueError(Not numeric: Performance counter statistics)
With the above options, the csv that simpleperf produces looks like
this:
Performance counter statistics,
123456789,raw-l1-dtlb,,(60%),
42424242,raw-l1-itlb,,(60%),
Total test time,1.001079,seconds,
Performance counter statistics,
123456789,raw-l1-dtlb,,(60%),
42424242,raw-l1-itlb,,(60%),
Total test time,2.001178,seconds,
Performance counter statistics,
[...]
That is, with "--interval-only-values", the "Performance counter
statistics," header is repeated every interval. WA current expects
it only in the first line. Modify the condition so that it is ignored
every time we find it in the file and not just the first time.
Workload Automation
+++++++++++++++++++
Workload Automation (WA) is a framework for executing workloads and collecting
measurements on Android and Linux devices. WA includes automation for nearly 40
workloads and supports some common instrumentation (ftrace, hwmon) along with a
number of output formats.
WA is designed primarily as a developer tool/framework to facilitate data driven
development by providing a method of collecting measurements from a device in a
repeatable way.
WA is highly extensible. Most of the concrete functionality is implemented via
plug-ins, and it is easy to write new plug-ins to support new device types,
workloads, instruments or output processing.
Requirements
============
- Python 3.5+
- Linux (should work on other Unixes, but untested)
- Latest Android SDK (ANDROID_HOME must be set) for Android devices, or
- SSH for Linux devices
Installation
============
To install::
git clone git@github.com:ARM-software/workload-automation.git workload-automation
sudo -H python setup [install|develop]
Note: A `requirements.txt` is included however this is designed to be used as a
reference for known working versions rather than as part of a standard
installation.
Please refer to the `installation section <http://workload-automation.readthedocs.io/en/latest/user_information.html#install>`_
in the documentation for more details.
Basic Usage
===========
Please see the `Quickstart <http://workload-automation.readthedocs.io/en/latest/user_information.html#user-guide>`_
section of the documentation.
