- Implementation of a gem5 device which allows simulated systems to be
used in the place of a real device. Currently, only Android is
supported.
- The gem5 simulation is started automatically based on a command line
passed in via the agenda. The correct telnet port to connect on is
extracted from the standard error from the gem5 process.
- Resuming from gem5 checkpoints is supported, and can be specified as
part of the gem5 system description. Additionally, the agenda option
checkpoint_post_boot can be used to create a checkpoint
automatically once the system has booted. This can then by used for
subsequent runs to avoid booting the system a second time.
- The Gem5Device waits for Android to finish booting, before sending
commands to the simulated device. Additionally, the device supports
a sleep option, which will sleep in the simulated system for a
number of seconds, prior to running the workload. This ensures that
the system can quieten down, prior to running the workload.
- The Gem5Device relies of VirtIO to pull files into the simulated
environment, and therefire diod support is required on the host
system. Additionally, VirtIO 9P support is required in the guest
system kernel.
- The m5 writefile binary and gem5 pseudo instruction are used to
extract files from the simulated environment.
- 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.
Add video-long.json and video-short.json files and

Test 0 (write) creates a file that is used by subsequent tests.
Therefore if this test is not specified withen selecting which tests to
run, izone will fail with an error.
To avoid this, check the tests list specified by the user andd add test
0 if necessary.
In order to show more detailed results for the iozone
workload, inform users to enable classifiers in their

When users specify tests, the parse_metrics()
function doesn't capture the last report name and its
results during the parsing process. Fix the
parse_metrics() function to make sure the data for
all reports are captured.

Pulling entries from procfs does not work on some platforms. This commit
updates get_properites() to cat the contents of a property_file and
write it to output file on the host, rather than pulling it (directories
are still pulled).
When enabled, this wil cause the instrument to insert a marker into
ftrace, while at the same time setting a GPIO pin high.
For this to work, GPIO sysfs interface must be be enabed in the kernel
and the specified pin must be exported.
Bbench only works on Android. It should advertise that fact by setting
supported_platforms to ['android'].
Telemetry is a Chrome browser workload that is only supported on
ChromeOS and Android.
With this option, only extensions packaged with WA itself will be
listed. Extensions discovered from other packages or from local paths
will not appear in the list.
A newer version of rt-app has been released. Built

Added functions to parse thread-mode results and
non-thread mode results accordingly, in addition
to rewriting the update_result() function.

When no files are listed for one the specified directoris, the
instrument checks whether there are any files in that directory on the
device. If that directory itself does not exist; that will result in an
error. This is now handled correctly.
The warning refers to trace.bin, which is not the extension that we use
for it. Instead, use the variable with the default trace
name (trace.dat) for the warning.
- fixed_before_start is a fixed time period equivalent to
temperature_before_start
- Changed existing *_between_specs and *_between_iterations callbacks to
be very_slow, as they should always run after everything else.
A quadratic is now fitted to single and two-core power measured across
frequencies. This quadratic is then used in projection of cluster power.
This mitigates issues with cluster powers going negative or "crossing
over".
There's a known issue that HDMI will lose sync with monitor, adding video kernel parameter will make the HDMI more stable for juno
> HDMI can lose sync with the monitor intermittently, particularly at higher resolutions.
> If you are affected by this then try adding a kernel command line argument that forces
> a video mode with reduced blanking, such as the following:
> video=DVI-D-1:1920x1080R@60
Failed jobs will now be automatically retired. This is controlled by two
new settings:
retry_on_status - a list of statuses which will be consided failures and
result in a retry
max_retries - number of retries before giving up
It is now possible to generate agendas for a set of extensions with
wa create agenda ext1 ext2 ext3 -o output.yaml
Confiuration will include all parameters for those extensions with
default values.
Dynamic modules may be loaded automatically on device initialization if
the device supports them. Dynamic modules implent probe() method to
determine whether they are supported by a particular deviced.
devcpufreq and cpuidle have been converted into dynamic modules
- standardisded on a single context argument
- removed Device.init() no longer necessary as initilize now
automatically gets propagated up the hierarchy. Renamed the existing
use of it to "initilize".
- related pylint cleanup.
uname is not available on all Android devices, and we cannot rely on
busybox for establishing the ABI, as we need to get the ABI before we
can depoly the right version of busybox.
Added -p option to the list command. This alows filtering results by
supported platforms, e.g.
wa list workloads -p linux
Also adding missing supported_platforms attribute to various extensions.
If an extension does not have this attribute, the assumption is that it
is supported by all available platforms.
In previous versions of Android, "mount" returned output in the format
similar to fstab entries, which is what list_file_systems expected. This
fixes it to be able to handle the more traditional "mount" output in the
format
<device> on <mount point> type <fs type> <options>
as well as continue to parse the Android output correctly.
Adding global aliases to parameters to fix old configs that still used
the deprecated "<ext name>_<param name>" format for specifying parameter
values.
- added initialze and finalize methods to workloads, which were the only
major extension types that did not have them
- Semanatics for initialize/finalize for *all* Extensions are changed so
that now they will always run at most once per run. They will not be
executed twice even if invoke via istances of different subclasses (if
those subclasses defined their own verions, then their versions will
be invoked once each, but the base version will only get invoked
once).
In both cases, the ABI is now obtained by executing "uname -m" on the
device and perfroming a mapping from the returned machine architecture
a known ABI. If no known ABI is found the architecture string itself is
returned.
- add IterationResult-level classifiers that get merged into every
added metric (saves having to pass the same classifiers to each
metric added).
- Added a global alias to csv result processor's use_all_classifiers
attribute.
- updated energy_model to accept dhrystone as well as sysbench as
the workload
- added "threads" parameter to sysbench (basically, an alias for
"num_threads") to be consistent with dhrystone
- added "taskset_mask" parameter to dhrystone to allow pinning
it to specific cores.
- Now works with earlier versions of the DAQmx driver. This is needed to
be able to run the server on Linux systems, which support older
verisions of the driver only.
- DAQ error messages are now properly propaged to the client (PyDAQmx
uses "mess" rather than "message" attribute to store the message in
the Exception obejects).
- pylint and pep8 fixes
Background processes may produce output on STDOUT. This could get
captured when obtaining the result of "echo $?" to get previos command's
exit code. So it's not safe to assume that output will always be an int.
Attempt to strip out superflous output before doing the int conversion
and, on failure, log a warning but don't error out.
Some options in config_example.py are not reachable. It makes users
confused. So make the options in the file as gobal_alias.

added more paths to pull by default when device.get_properties is
invoked during run initialization. Also moved the LinuxDevice
implementation into BaseLinuxDevice, so that AndroidDevice tires to pull
the same files (on top of the Android-specific stuff).
list_or_* functions (e.g. list_or_string) will now always return a list,
however will accept lists or indivitual values. Also added a list_or()
generator function, similar to what already exists for list_of().
- Do not try to use a pager if it explicitly disabled with PAGER='' in
the environment.
- If terminal size is identified as (0, 0), fall back to default (80,
25).
As instrumentation can be enabled/disabled for a specfic workload
execution, it is sometimes not enough to verify that an instrument has
been installed for the run; one might need to check whether it is
currently enabled.
Since a command would still be running on time out, it would prevent
issuing subsequent commands in the same SSH shell, make it look like
the device has become unresponsive.
If a timeout condition is his, send ^C to kill the current foreground
process and make the shell available for subsequent commands.
- Adding "classifiers" field to Metric objects. This is a dict mapping
classifier names (arbitrary strings) to corresponding values for that
specific metrics. This is to allow extensions to add
extension-specific annotations to metric that could be handled in a
generic way (e.g. by result processors).
- Updating telemetry workload to add classifiers for the url and internal
iteration (or "time") for a particular result.
- Updating csv result processor with the option to use classifiers to
add columns to results.csv (either using all classifiers found, or
only for the specific ones listed).
The key file must only be readable by the owner. If the specified key
file has different access permissions, create a temporary copy with the
right permissions and use that.
np.vectorize was being unconditionally invoked at top level. On an
ImportError, np as set to None, so this was resuling in an
AttributeError when loading the module if one of the dependent libraries
was not present on the host system. This moves the invocation into the
try block with the imports to avoid an error when energy_model module is
loaded by the extension is not used.
- adding missing cpu id conversion to set_cpu_min_freq
- adding "exact" parameter to set_cpu_frequency; only produce an error
when the specified frequency is not supported by the cpu if "axact"
is set; (otherwise let cpufreq decide what the actual frequency will
be).

Make sure when migrating sshd to root cgroup also migrate their
children, including the bash for the wa session. So the subsequent
processes kicked off from that shell can be taskset to any cluster.
Matplotlib defautls to the GTK backend. This can cause problems when
running in a headless session (e.g. over SSH). Since energy_model
istrument generates PNG plots, rather than rendering directly to UI, it
doesn't actually need GTK; set backend to AGG so that energy_model works
in headless environments.
