This instrument will log serial traffic to a file. The idea is to
assist with debugging development boards, as otherwise there is a
chance that crash reports, for example, are lost when the device is
reset by WA.
It logs the pre-run and post-run traffic to preamble_serial.log and
postamble_serial.log , respectively, in the top-level output
directory. Serial logs for each workload are stored in the appropriate
workload directory as serial.log.
As we are tying up the serial port, we stop the logging when the
device is reset to allow board such as the Arm Juno to be reset via
the serial connection.
Since daq-server has been split out into a separate package, daq setup
is no longer part of WA documentation. This resulted in a warning when
building the docs.
As part of resolving a resource, record its MD5 hash in the output
metadata. In order to enable this, resource resolution is now done via
the context, rather than directly via the ResourceResolver (in order not
to introduce a context dependency in the Gui object, context now
emulates the resolver interface).
Extracting trace and pulling the trace file from the target can take a
relatively long time, as the trace file can be tens, and even hundreds,
of MB. Add an info-level log message to inform the user why WA execution
appears to have paused for a few seconds.
- Add missing descriptions to backends.
- Describe how to get instrument-specific parameter descriptions in the
help for instrument_parameters param of EnergyMeasurementInstrument
Add an instrument which wraps the devlib screencapture poller, which
allows us to capture a screenshot from the device every `period`. The
`period` is configurable based on the user requirements.
All captured screenshots are named according to the timestamp on the
device, and are placed into an output directory (screen-capture)
within the job directory.
resistor_values is an array of float and not int as the shunt resistors
are most of the time lower than 1 Ohm.
With kind=list_of_ints, all resistor values are rounded to 0. Replace it
by list_of_numbers
sample_rate_hz is an int used to get sample period and to compute energy.
Changes its type from str to int
With these 2 fixes, the daq instrument has been successfully tested with
NI DAQ6211

Arm Energy Probe with arm_probe has been recently added in devlib's
instrument.
Add the arm_energy_probe in the WA list of Energy measurement instruments

energy instruments might need to save platform specific configurations in
order to help to reproduce the use case. Such configuration should be saved in
__meta directory.
Add the directory path as a parameter of get_instruments() to save such
informations

Both the instrument and utility functions were called `trace-cmd.py`.
`"-"`'s are not valid python identifiers therefore when trying to import
the `trace-cmd` module this causes an error.
- Add an option to the poller binary insert a marker into ftrace that
aligns with the first output entry. The option is exposed as an
instrument parameter.
- If this parameter is set, the resulting .csv will be post-processed to
update the timestamps to align with trace-cmd output.
- Change poller artifact names to use - instead of _ to be consistent
with trace-cmd artifact naming.
