We remove the requirement for rt-app to run on a rooted device as this
does not appear to be required. We make sure that we run the workload
from a directory where we have write permissions by first changing the
directory before executing the workload (in_directory argument of
invoke).
In the case that the device is rooted, we run rt-app as
root. Otherwise, we simply run the workload.
By default rt-app writes to stderr, not to stdout. Therefore, if we
only sample the stdout, we get no output from the workload itself.
With this change, we redirect stderr to stdout to allow us to get the
workload output.
ExecutionContext.end_run() does final updates to the run info in the run
output (final status, run duration, etc). This was previously accessed
via self.output in the context. Typically, this would correctly resolve
to the run output, as there would be no current job. However, in the
event of a crash, current_job would be set, and this would resolve to
the job output itself, resulting in run info not being updated. Use
run_output to avoid this.
- RebootPolicy: correctly handle being passed another instance of
RebootPolicy on creation; this a requirement for it to be usable as a
ConfigurationPoint kind.
- RebootPolicy: move static method to above __init__ (consistency).
- RunConfiguration: handle deserialization of 'device_config' entry.
- RunConfiguration: move static method to above __init__ (consistency).
Save classifiers at Result as well as Metric level. Reason: when
processing output, one might want to filter complete results, as well as
individual metrics. While it is in theory possible to get the
classifiers for a job by simply extracting the common classifiers
between all metrics, this fails when there are no metrics generated for
a job (note that one might still want to process the output in this
case, e.g. for the artifacts).
Set target_binary as a class, rather than instance, attribute. This
happens only only once per run, and setting it as instance attribute the
first time, makes it unavailable for subsequent instances of the same
workload.
Do not explode if a result file for a job is missing when loading a
RunOutput. Specify job status as "UNKNOWN" and add the exception from
attempting to load the file to the events.
Fix an issue introduced by commit 42fb3eb
framework/workload: make "no matching package" message more useful
PackageHandler was incorrectly passing self.name into the error message
instead of self.owner.name.
Make the error message reported when no matching Android app package
could be found more useful by including the workload name, and, if
applicable, sought version.
Always prepend the format for the file into the downloaded filepath to
ensure matching is correctly performed. Previously the ogg file did not
specify this causing it to be re-downloaded for each run.
Rename the `start` method to `run` as this is what is what is called
by the threading module's `start` method, otherwise this causes the
polling to be done in the main thread blocking execution.
Add support for loading plugins from packages that register themselves
with WA by writing their names into $WA_USER_DIRECTORY/packages.
This is functionality that existed in WA2 and was omitted in WA3 until
now.
Output processor names are converted to identifiers when they are
loaded. Ensure the same thing happens when looking up installed output
processors with get_output_processor().
In devlib the default working directory has changed causing the workload
to look in the wrong directory, now the workload should use the passed
working directory and extract the relevant name from there.
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.
Allows setting of select android runtime configuration for devices running
chromeos and which support android. Currently only 'brightness' is functioning
correctly therefore the other parameters are only enable for standard android devices.
Previously when validating cpufreq runtime parameters it would check too
early whether the cpu was online, not allowing for the fact that the cpu
might be being onlined before the parameter was committed to the device.
To improve reproducibility of tests, it could help to ensure that the
same screen orientation is used on media playback.
This adds a new workload parameter which allows to ensure a LANDSCAPE
mode, which can be useful to better represent video playback scenarios.
When not enforced by the agenda, we enforce a PORTRAIT orientation.

Fix the setting of runtime parameters when the casing of the parameter in
the agenda does not match the "canonical" casing.
To make the writing of agendas easier, the casing of the parameters is
supposed to be ignored. To achieve this, parameter names are converted to
caseless_string type before they are looked up.
caseless_string's do not work with dicts. Both __contains__ (used for
the "in" operator) and __getitem__ (used for the [] operator) implement
hash-based look up, and it is not possible to have a caseless_string
match against multiple hashes to cover the different casing
possibilities.
So instead, iterate over the items in parameters dict, comparing the
caseless_string name to the key, and returning the value if it matches.
On some devices an installed apk filepath can contain an '=' character
which was previously used to end the regex match. Now match with the
package name as well to ensure the file path is extracted correctly.
Uses os.eviron as the default environment for creation of a
MetaConfiguration object, this allows an instance to be created without
providing any parameters and fixes re-creating an instance from pod.
Changed location of revent binary on target to be a class attribute so that
it is shared across all instances. Also changed discovery method to a
static method which can be memoized to prevent the target being queried
unnecessarily.
use the new get_target_description() when initializing the target inside
TargetManager, instead of manually searching through results of
list_target_descriptions().
The show command will try to use pandoc and man to display the relevant
information and will fall back to printing the markdown if pandoc is not
available.
Instead of taking an extension as a parameter and assuming there it has
an attribute 'parameters' instead take a list of parameters directly
which allows the method to be used with parameter lists with different
names.
Make TargetInfo an attribute of run output, replacing the read/write
methods for the targetfile. Instead, always load it on creation, if
targetfile exists (useful for external scripts), and have a method to
set it after creation (uselful during WA run, where the output is
created before connecting to the target).
Fix TargetInfo.from_pod(). As part of creating the POD, some of devlib's
classes such as Cpuinfo, get serialized. Since they are from devlib,
they do not implement WA's serialization interface, and are instead
serialized by extracting their internal structures. They are then not
deserialized properly, since their __init__'s expect text rather than
parsed structures.
This implements deserialization functions for these classes which
initialize them properly from TargetInfo POD.
Fix output when running for a specified number of loops (rather than
duration) and adding delay to threads. Previously, the output for the
last thread was not printed due to a missing check for a negative
duration.
Don't construct an ArtifactType in Output.Add_artifact, the Artifact
class does that for us.
Next, fix the use of a nonexistent attribute Artifact.valid_kinds
Previously only the top level help message would ever be displayed,
this was caused by 'parse_known_commands' automatically displaying the
default help message and exiting before any of the custom plugins are
loaded. Now ensure this flag is never passed into the method.
Remove wa.framework.plugin.Artifact and associated references. The name
of the class clashes with the class from output and can potentially
cause confusion.
The original intention for this was to be an "expected artifact
descriptor" of sorts that plugins can specify for validation purposes,
but that functionality was never implemented. Given that the framework
has undergone significant changes since this was implemented, it's not
clear that this is the best way to go about the original goal.
Therefore remove this for now.
To reflect that the current implementation of ReventWorkload uses an APK
file on the device the name has been changed appropriately and the
relevant workloads have been updated.
- Use get_config_point_map() to ensure aliases are parsed from
configuraiton.
- Only set the default for a name only if it matches the corresponding
param's name (i.e. don't set for alises).
The report_results parameter has been removed as the parsing functionality
is now performed by the `uxperf` processor therefore to report the
results of the application launch time ensure the processor has been
enabled.
Changes from checking if there are deployable assets to checking for
discovered assets. This allows for automated pushing of assets without
invoking the resource getters, for example pre discovered files.
Logcat entries are split on a ':' followed by a space so ensure this
is present in the line instead of just a ':'. Some devices have entires
without the trailing space causing an error.
Rename loop variable inside _write_outputs so that it doesn't clash with
the argument that gets passed (this resulted in writing to the wrong
location when writing a run artifact from a job).
Add a simplified version of the uxperf processor. This version only
extracts and calculates durations of UX_PERF sections from logcat.
Currently, this does not correlate them agains frames/fps data.
Now that job output processing happens even on failure, this will result
in workload result processing also being triggered. We should not try to
extract failed workload results, so check the job status before
attempting to do so.
Ensure that job output is processed even if a workload fails. This is
because output processing includes things like extracting logs, which
we still want to happen on failure.
Job status is now also set correctly when an error occurs during output
processing rather than actual running of the workload. Previously, the
status would be correctly set to PARTIAL in the inner except clause,
but the exception is then re-raised, and the status was "upgraded" to
FAILED in the outer except clause.
Do not concatenate start/stop markers to the action string with a '_',
delimit them with a space instead. This will make easier to parse the
message afterwards.
Mandate that either a package name is specified or the owner defines
supported package names. This prevents any apk file in the correct
location incorrectly being resolved.
Some workloads can insert timestamped markers into the logs if this
parameter is enabled in their automation. These markers can then be
used to look at measurements for specific parts of the execution.
These two lists are updated by workloads as assets are discovered and
deployed. As these are defined as class attributes in the base Workload
class, the same two list instances are shared between all classes. This
results in subsequent workloads re-deploying assets from the previous
workloads, and may lead to mismatches with deployable_assets, which is
overwritten on per-workload basis.
Make these into instance attriutes to prevent these issues.
Some targets need more than 5 seconds to re-connect to a wifi network
after disabling airplane mode. To fix that, poll for network up to 20
seconds and show a warning if unreachable.
Upon clearing data of a previously installed application the runtime
permissions can also be cleared, to avoid having to reinstall the
application all available permissions are explicitly granted to the
required application.
Allows for automatically pushing a set of arbitrary assets to the device
during initialization and adds a parameter to specify whether the assets should
be removed again at the end of the run.
Adds various methods that are used in UxPerf workloads and additional
helper class for UxPerf specific functions.
Adds a class to contain UxPerf specific functions.
In order to properly enable verbose logging for plugin enumeration,
verbosity option must be extracted before commands are processed, and
therefore before all valid arguments are known.
ArgumentParser.parse_known_args() is used for this, which will collect
all unexpected arguments into an "extras" list, rather than raising an
error. This, however, has an outstanding bug, where if say option '-v'
is known and '-f is unknown, args '-v -f' will be parsed correctly (with
'-f' being collected into extras), but '-vf' will not, resulting in an
error.
To get around this, pre-process sys.argv to detect joined options and
manually split them into separate args.
We currently populate results_so_far with a JobOutput for each Job and then a
Result for the RunOutput. This results in a bug when trying to access the
id/label/iteration.
This is fixed by always ensuring the we store Output objects and not
Results (results_so_far is renamed to outputs_so_far to reflect this), and
treating the RunOutput specially in _write_outputs.
Update the File and Executable resource string representations to
actually include the words "file" and "executable" respectively to make
messages containing these representations (e.g. when a resource is not
found) clearer.
--diable can now be used to disable both intruments and
result_processors from the command line (overriding configuration
files). Rename variable names to reflect this.
Replace update_enabled_instruments with update_augmentations, which
correctly splits instruments and results processors from augmentations
configuration values.
While instruments and processors are now handled uniformly in
configuration, they still need to be handled differently during actual
execution. This is the point where they get split again.
Remllace merge_instruments_result_processors with merge_agumentations
which is updated to properly merge the new unified "augmentations"
configurations.
Rename ConfigurationPoint "instrumenation" to "augmentations". Unlike
WA2, in W3, instruments and result_porcessors are handled identically in
configuration (though there're still distinct pulgin types).
"instrumentation" and "result_porcessors" entries in configuration are
now aliases for the same configuration point, which is renamed to
"augmentations" to reflect the fact that it contains both types of
plugins.
Expose PluginLoader's get_plugin_class via PluginCache. PluginCache is
basically intented to act like a PluginLoader, except when instantiating
plugins, the "default" parameter values are taken form the cached
configruation, rather than the actual defaults defined in the Plugin's
parmaters.
Now that we add an event when logging errors, we need to avoid passing an
exception object directly to the logger. Otherwise we end up adding the
unserializable Exception object to the events list, which causes an error when
trying to write the output.
This maintains the default behaviour of bailing out immediately if any workload
fails in initialize(), but adds a setting, bail_on_init_failure, to change this
behaviour optionally. This can be useful where WA is being used more as a batch
processor.
Changes to the Status enum introduced by 31a535b5 and a9959550 broke
ran Jobs summary status at the end of the run. This fixes it so that the
total number of jobs and individual status counts are reported
correctly.
The generic "frequency" runtime parameter was only being set when there
are common frequences between avialable cores. It should always be set,
even if there are no frequencies in common, as it still valid to use it
with special values "min" and "max", in which case it should resolve
correctly to the appropriate frequencies.
Set context for the loggers of the Runner, the workloads and the
installed instruments and processors. Errors/warnings logged by these
entities will be automatically added as events.
Add ContextLogger wich extends logging.Logger's warning and error
methods to automatically add the message to the context's events (if a
context has been provided).
This enables you to do things like:
global:
runtime_parameters:
airplane_mode: true # This improves repeatability of energy measurements
workloads:
- name: foo
- name: bar
- name: geekbench
runtime_parameters:
airplane_mode: false # Geekbench requires network, and we don't care
# about energy for that workload anyway
For some reason I didn't look at the WA2 instrument until afer I
wrote this, so it's different in how it handles 'before/after'
quantities (which I called 'momentary' in the code) - instead of
adding a 'mean' it just adds two separate metrics: one for before and
one for after. Personally I think this is more useful (esp. for
temperature) but if necessary I can revert to the old behaviour.
This also doesn't add the helpful classifier telling you the hwmon
device, because we don't have immediate access to that info from the
devlib Instrument. If necessary I'm sure it could be added later.
Furthermore it doesn't have a parameter to filter the sensors, just
collects from them all.
Where backends have the capability to collect from multiple devlib
Instruments, EnergyMeasurement currently appends 'device' keys to the
names of metrics reported by those Instruments. Where multiple
Instruments are indeed used, it then sums up equivalent metrics to
produce the 'normal' metric without the 'device' keys
appended.
E.g. If you have two ACME 'devices' enabled you will get something
like
'device_total_energy_iio:device0' and
'device_total_energy_iio:device1', which will be summed to produce
'device_total_energy'.
However when only one Instrument is actually instantiated, this is
not needed and not done. Therefore just directly produce the metric
with the name originally given by devlib (i.e. in the example,
'device_total_energy').
Fully matching an APK resource requires the file to be present locally,
so that its metadata can be queries. HTTP getter was matching against a
remote path so the match was failing.
The matching now happens in two stages == first partial path-only
matches are established. Secondly, all partial matches are downloaded
and final match occurs against downloaded files.
This method is used to partially match a resource; its implementation
cannot rely on the resource file actually being present and must match
against the specified path alone.
match() implementation now defaults to match_path(), as for most
resource types, the path is sufficient to uniquely match a resource.
Devlib's get_data API can return None when something goes wrong -
this currently results in us attempting to add a non-existent
artifact.
To avoid this confusion, check and use the return value from
get_data, instead of assuming that it will write data to its
'outfile' parameter.
Currently if you get confused and write a config with something like:
energy_measurement:
acme_cape
Then you get an error when we try to 'iteritems' on the value
'acme_cape'. Instead, explicitly check for this case.
- Fix start/stop methods of sysfile_getter, which where still using the
WA2 mechanic of prefixing "slow_" to the name to indicate priority,
and consequently weren't being invoked.
- Call super inside cpufreq's valide(() to make sure tempfs path is set.
- Make sure TargetManager.finalize() actually gets called at the end
of the run.
- Overrule the "diconnect" parameter behavior for gem5 and make sure it
always disconnects. This necessary for stats to be generated properly.
devlib's CGgroups module logs things at INFO level. The information it
logs is too detailed for what WA considers "INFO", and should be logged
at DEBUG level instead.
Gem5Platform requires a host output directory as one if it's
instantiation parameters. This is not something we want to expose a
configuration parameter to the user, as for WA, the standard output
directory ought to be used.
Up to this point, WA's target instatiation process assumed that all
parameters came from the user, and there was no way for WA itself to set
them. This commit adds extra_platform_parms argument to
instantiate_target, to remedi this.
extra_platform_parms is then used to set the host output directory for
gem5 appropriately.
(linux|android)_gem5 devices were being described as having gem5
platforms but standard linux/android connections. This commit fixes this
by making sure that the gem5 connection is used.
Seem I cherry-picked the geekbench workload from my WIP branch
without testing properly, and missed a fixup commit. Here's the
content of that commit, which fixes some missing updates from WA2 ->
WA3 APIs.
Devlib's ACME instrument uses iio-capture under the hood, which can
only capture data from one IIO device at a time. Devlib's instrument
API expects to produce a single CSV file for the Instrument, with a
single axis of sample timestamps. These two things cannot be
correctly reconciled without changing the devlib Instrument API -
get_data would need to be able to return two distinct sets of data.
Instead, where required WA will instantiate the ACME instrument
multiple times (once for each IIO device), producing two separate CSV
files. Aggregated energy info (as opposed to timestamped samples of
energy data) _can_ be meaningfully combined from multiple IIO
devices, so the derived stats are summed.
This requires altering the internal API of the energy_measurement
module - rather than a single instrument the super-instrument now has
a dictionary mapping 'device' keys (this is really an arbitrary key,
but I think that 'device' is a justifiable metaphor for whatever
might separate multiple instruments, plus it is the terminology used
by IIO/ACME) to Instrument objects. Existing instruments simply
return a dict with a single entry, with None as the key.
It may in future be possible to solve this problem in devlib's ACME
instrument by avoiding the use of the iio-capture tool. In that case,
it should be possible to basically revert this patch and get the
required funcitonality from devlib.
Runtime param names from config were matched against names available on
for the target using an overly-loose regex that resulted in the wrong
config point being returned.
Use caseless_string matching instead.
As paramters defined by energy_measurement instrument backends were not
used in instantiating the backends, but the underlying devlib
instrument, the values did not undergo the usual Plugin parameter
setting perocedure. In particuar, type conversion would not take place.
Make sure backend parameters are validated properly by setting them on
an obj_dict before passing them to the devlib instrument.
Some workloads, such as Geekbench, may phone home and report data about the
device they are running on. This poses a risk for users that are testing on
unreleased or otherwise confidential devices - perhaps they use a standard
agenda to run a large battery of tests, in which case they may forget to disable
these dangerous workloads.
This provides a mechanism to prevent running those workloads from running by
setting allow_phone_home=False in the user configuration.
Currently if your config contains
typo_for_a_global_alias: 1
You will get an error where we try to call 'iteritems' on the value 1. This
commit re-orders the checks so that you instead get an error for the
unrecognised 'typo_for_a_global_alias'.
Differences from original:
- Standard renaming and rearrangement of imports
- UiAutomation.java now uses the setup() and runWorkload() phases which weren't
present before.
Due to the nature of modern Android devices, in order to usefully
interpret the power* events, you more and more often need to know the
kernel's view of temperature too. Therefore I think enabling the
thermal event group by default makes sense.
- Add "activity" property to PackageManager exposing the underlying
apk_info attribute.
- Add "view" class attribute to ApkWorkload, initialized to None
- If "view" is not set for a particular workload, set a default based on
the package and activity of the underlying workload.
