A new 'ParameterDict' has been added that automatically encodes and
decodes values when they are store in a dictionary. The dictionary uses 2 characters
prefixed to each value to store the original type information, e.g. 'fl' -> list of
floats, before being passed through a url encoder. The reverse process happens on retrieval.
To access the encoded values an `iterEncodedItems` and `getEncodedValue` methods have been added.
The appropriate unit tests have also been added.
UxperfParser class is moved from the UxperfResultProcessor class into a new
python module in utils. This will help to use the UxperfParser even when
the result procesor is not configured.
Fixed new gamemode not being set for compatibility mode.
Fixed input buffer not being flushed causing replay to fail.
Fixed infinte loop if revent recording did not end correctly.
Updated revent binaries.
When collecting ftrace events, the instrument will insert frequencies
into the trace to make it possible reconstruct power states when there
were no frequency transitions during the measured period.
The format in which frequencies are inserted is different in devlib.
Since post-processing scripts may be run on traces collected by devlib
as well as WA, it needs to support both formats.
- Corrected the depency for opencv bindings. Even though the library is
imported as "cv2", the package containing it is called
"opencv-python".
- pylint: ignore no-member warnings; cv2 pulls it's memebers dynamically
from the underlying libopencv, so pylint can't see them.
Due to inaccuracies in revent playback, the resultant state does not
always match the templates precisely causing state detection to fail.
To help this images are now scaled to different sizes before being
matched to the templates to compensate for slight variations in size.
When using 'check_exit_code' and 'as_root' options for adb_shell with
a command containing single quotes, the provided command was escaped
twice which has now been avoided.
- Updated the revent parser to handle the new revent format.
- Updated the revent parser to expose device info and recording
metatdata.
- The parser can now be used in streaming and non-streaming mode (stream
events from the file as they are being accessed, or read them all in
at once).
- -g option added to "record" command to expose the gamepad recording
mode.
- Corrected code highlighting and phase names in documentation
- Fixed check_states paremeter not being honoured
- Moved state dependencies check to happen earlier in execution
and to be a user facing error
It looks like on recent systems, adb has started to correctly forward
stderr from the target device to stderr on the host (wereas in the past,
it got output to stdout on the host). This commit makes sure that
stderr gets correctly forwarded to the coller in cases where return code
checking was not enabled.
When running the stand-alone cpustates script and specifying a timeline
file (which causes the corresponding reporter to be enabled), a
timeline report is generated in addition to the usual cpustates and
parallelism reports.
Up to this point, the main() of the stand-alone script was expecting
exactly two reports and so it crashing when running with the timeline
option. This commit fixes this case.
CalledProcessErrorWithStderr is a subclass of CalledProcessError that
also takes stderr output. Both that and normal output must be passed as
keyword arguments. They were being passed as keyword arguments inside
_scp() of SshConnection, causing cryptic errors to appear.
Additionally, "output" was not being properly poped off before invoking
super's init.
Add method to automatically check against a dictionary of known package
versions that don't work well with AndroidUiAutoBenchmark workloads.
Raises an exception if found.
- Added statedetect.py in utils which is a standalone module that
contains all the methods needed for state detection
- Modified the setup() and run() methods of the GameWorkload class
in common/android/workload.py to have a parameter that enables
state checks and run the check after setup and run if requested.
State detection uses the template matching method available in
OpenCV to determine the state of the workload by detecting
predefined unique elements on a screenshot from the device.
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.
Standard string representation of a subprocess.CalledProcessError does
not include the output of the command, so it was not previsouly included
in the resulting DeviceError. This commit ensures that the output is
propagated, regardless of whether it came from stdout or stderr of the
underlying process.
cpustates can now handle the lack of a start marker in three ways:
- try: If the start marker is present only the correct section of the trace
will be used, if its not the whole trace will be used.
- error: An error will be raised if the start marker is missing
- ignore: The markers are ignored and the whole trace is always used.
If an exception is raised inside a generator it cannot be continued.
To get around this exceptions are now caught and later output via the
logger.
Also added logger setup when running cpustates as a standalone script
This allows the return value of a function to be cached so that
when it is called in the future the function does not need to
run.

The stock camera app as of Android M has changed. This commit updates
the ui automation to work with this new app. As part of this change
it was required to bump the API level of the ui automation to 18.
Also made the teardown of the capture workload close the app like the
record workload.
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
They way we were attempting to get return codes before always gave
us a return code of the previous echo, therefore always `0`.
This commit adds the newline into the last echo.
Previously, only reports that were generated were returned. With this
commit, there will be an entry for each active reporter in the returned
list. If a reporter did not produce a valid report, the entry will be
None.
This ensures consistent output, even if a run time issue causes a
reporter not to produce a report (e.g. if cpufreq events were not
enabled).
Previously Linaro U-Boot releases had a bug where they used \n\r
as the line ending. This has now been fixed which caused
issues with WA. WA now detects the U-Boot version and uses the
coresponding line ending.
Fixed error in percentage when frequency is 'None'. Now default to 0 in these cases
cpu_utilisation is now a separate parameter in cpustate. Now generates a floating point number representing the utilisation based on the maximum frequency of the capture. No longer performs averaging of values, this can be done as a post-processing step
cpu utilisation now based on the max cpu freq per core, not max captured freq overall
As of ADB 1.0.35/Android N, it will return the exit code of the command that it runs
This code handles this scenario as before WA treated a return code from ADB as an
error with ADB.
- 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.
Depending on the kernel, sched_switch events may be formatted one of two
different ways in the text output. Previously, we've only handled the
"old" format. This commit updates the parser to handle the new format as
well.
- Deal with the dropped connection on issuing "reboot"
- Introduced a fixed initial delay before polling for connection to
avoid re-connecting to adevice that is still in the process of
shutting down.
