In Android M and above, there is a new method of collecting fps
statistics, using gfxinfo rather than SurfaceFlinger, but the
SF method is still available however.
This parameter lets the user decide whether to always use SF,
or to allow the instrument to pick the best method based on
Android version it detects.
The summary energy metric was being calculated incorrectly. Instead of
dividing power by the sampling rate, it was being multiplied by it and
divided by a million for some reason.
perf instrument was forcing killall() to run as root on Android devices.
This constraint was preventing perf from being used on unrooted devices.
However, it appears that it is possible for killall() to succeed on at
least some devices as a regular user.
This commit removes the constraint. Since killall() will default to
running as root whenever possible, the instrument will still behave
correctly on rooted Android devices where root is required.
Changed the `files` parameter to be mandatory and added check to
ensure that at least one file is passed in configuration otherwise
the instrument crashes.
Android marshmallow uses a different default view for logcat
therefore prevented output from being extracted. The regex
expression has been updated to include matching the new format.
Fixed a bug, where "ui" runtime parameter was being set regardless of
the underlying platforms for "freq" iterations, causing the to fail on
non-ChomeOS devices.
Add a new parameter to fps instrument to specify the time period between
calls to ``dumpsys SurfaceFlinger --latency`` in seconds when collecting
frame data. A lower value improves the granularity of timings when
recording actions for UX Performance metrics.
Processing logic for frame statistics can be moved out of fps instrument
to a new utility file. This will allow result processors to use the same
logic to produce frame statistics on a subsection of the data
produced by the fps instrument.
- Updated poller binary to propery check for errors (e.g. on attempting
to open a file) and report them to stderr
- Updated the file_poller instrument to collect poller stderr output
into a log file and to check the log for errors or warnings on
completion of an iteration.
- device.is_rooted check was being perfromed inside validate() which
gets invoked before the device is connected. This worked for most
Android devices, because connections is a no-op for them, however
failed for Linux targets. The check is now performed inside
initialize().
- Added _is_ready() check inside is_rooted to catch similar problems
quicker in the future.
energy_model instrument generates job specs during the run. One of the
things it does is set "ui" runtime parameter to "off". This parameter
only exists for ChromeOS devices. This commit ensure that the parameter
is not set when running on any other device.
If the tar.gz already existed on the target device the instruments would
fail. This fix adds the "-f" option to gzip to force it to overwrite the
file.
Servo is a debug board used for Chromium OS test and development. Among other uses, it allows
access to the built in power monitors (if present) of a Chrome OS device. More information on
Servo board can be found in the link bellow:

Previously the sensor name was just appeneded to the end of the
previous sensors name.
Now the hwmon name is added as a classifier of the metric.
If the hwmon sensor has a label, the metric will use this for its name,
if it does not then the sensors kind and ID will be used e.g. temp3
Commit 724f6e590e changed sysfile_getter
behavior to first tar up copied files and then gzip them. Tarball name
needs to be updated to not include '.gz' extension.
- android/workload: emoved an extra bank line between methods
- trace_cmd: define member attribute inside __init__
- adb_shell: ignore pylint warning about too many branches in this case
The timeout for the pulling the trace file after the run is being set
based on the time for which the trace was collected. For workloads with
short execution time, but large number of events, the resulting timeout
might be too short. To deal with this, do not let the timout be shorter
than 1 minute.
Added:
get_binary_path: Checks binary_directory for the wanted binary, if
if its not there, it will use which to find a
system one. returns the full path
install_if_needed: will install a binary only if it is not present.
Changes:
- Busybox is now deployed to non-rooted devices
- is_installed has now been removed as the new functions supersede it
- binaries will now always be installed to `binaries_directory` and
not system folders.
- updated workloads to use these new functions
- rt-app and sysbench might still need work
When report_on_target option is set, binary trace will be "reported"
into a text version on the target device. This removes the need for
trace-cmd to be installed on the host, in which case that should not be
reported as an error.
- Summary metrics are now calculated from the contents of energy.csv and
added to the overall results.
- Added a new "strict" parameter. If this is set to False, the device
check during validation is omitted.
