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.

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

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.
cpustate result processor generates a view of the cpu subsystem power
state during execution of a workload from cpu_idle and cpu_frequency
ftraces. There exists a period before the first events in those
categories are seen where the state of the cpu subsystem is (partially)
unknown and it is reported as such by the result processor.
Unknown state usually exists for a relatively short period of time and
is generally not a big deal. For certain kinds of workloads, however, it
may constitude a significant protion of the trace.
Changes in this commit attempt to deal with this by a) reading starting
cpu frequencies and writing them into the trace, and b) nudging each
core to bring it out of idle; this happens before the start marker, so
that the system state between the markers should be completely known.
In order to execute as root, the command string gets echo'd into so;
previusly, double quotes were used in echo, which caused any veriables
in the command string to be expanded _before_ it was echoed.
- Compiled regular expressions in EVENT_PARSER_MAP now get handled
correctly.
- regex_body_parser now attemts to convert field values to ints,
bringing it inline with the default parser behavior.
- There is now a regex for sched_switch events.
- adb protcol uses "\r\n" for line breaks. This is not handled by
Python's line break translation, as not a file. So spliting on '\n'
when extracting the exit code resulted in stray '\r' in the output.
- adb_shell expects exit code to be echoed on the same line. This may
not have been the case if latest output from executed command was not
a complete line. An extra echo will now ensure that the exit code will
be on its own line even in that case.
- Allowed telnet connections without a password.
This is required as part of the upcoming Gem5Device, which uses a
password-less telnet connection to communicate with the device.
