- Refactored the Gem5Device to avoid duplicated code. There is now a
BaseGem5Device which includes all of the shared functionality. The
Gem5LinuxDevice and the Gem5AndroidDevice both inherit from
BaseGem5Device, and LinuxDevice or AndroidDevice, respectively.
If the parameter merge_channels is set to true (false by default).
DAQ channels that have consecutive letters on the end of their names
will be summed together. E.g: A7, A15a, A15b becomes A7, A15
You can also manually specify a channel mapping by setting
merge_channels to a dict. .
- Remove the unbind and rebind for the VirtIO 9P mount method as gem5
now checkpoints the basic state of the device. This allows us to
just mount it assuming that checkpoint have been created correctly.
- Move the processing of Android properties to an internal
method. This allows the Android properties to be extracted without
extracting those of the Linux device.
- Redirect the output from 'dumpsys window' to a file and pull the
file as opposed to extracting the output from the terminal. This is
more reliable in the event that another process writes to the shell.
- Replaced hard-coded pexpect expect string with UNIQUE_PROMPT.
- Changed the capture_screen debug to a warning to make sure that the
user knows when it happens.
- Fixed the logic for checking when a file exists. Previously, if the
output could not correctly be processed (ValueError) then we just
assumed that the file existed if there was any output at all. This
is clearly not a good default. Changed to default to False if it was
not able to process the output as this seems to be the safest
option.
- Changed ad hoc filename extraction to use os.path.basename.
- Removed the processing of some kwargs and defaults that are handled
by the parent class.
- Stopped overriding some paramaters which were purely defined in the
Gem5Device.
- Added the gem5_binary option to the agenda which allows a different
gem5 binary to be specified. This allows WA to be used with
different levels of gem5 debugging. as well as allowing non-standard
gem5 binary names and locations.
- Replace ugly while True loop with a simple regex substitution
achieving the same thing. This is required to match the command in
the shell output when the command wraps around due to the length of
the command.
- 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
update spreading-tasks.json. The originals can be
found in git.linaro.org/power/rt-app.git repo.

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
agenda or config file.

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
binaries from git://git.linaro.org/power/rt-app.git.

Added functions to parse thread-mode results and

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.
