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.
Previously you could have `override` set to True on parameters that
only existed in the current scope.
Now if you try to override a parameter that doesn't exist higher up
in the hiarchy you will get a ValueError.
Previously if parameters with the same names and override set to True
were added to an extension at the same level one would silently
override the other.
This is no longer the case and an error will be show instead.
Also added tests to check that this is handeled correctly
- Two different parameters may now have the same global alias as long as
their types match
- `extension_asset` resource getter now picks up the path to the mouted
filer from ``remote_assets_path`` global setting.
Added two commands to WA to record and replay input events using revent.
As part of this also added the ability to get a device model from
android and linux device. This may need to be improved in the future.
Added:
get_binary_path: Checks binary_directory for the wanted binary, if
if its not there, it will use which to find a
system one. returns the full path
install_if_needed: will install a binary only if it is not present.
Changes:
- Busybox is now deployed to non-rooted devices
- is_installed has now been removed as the new functions supersede it
- binaries will now always be installed to `binaries_directory` and
not system folders.
- updated workloads to use these new functions
- rt-app and sysbench might still need work
When report_on_target option is set, binary trace will be "reported"
into a text version on the target device. This removes the need for
trace-cmd to be installed on the host, in which case that should not be
reported as an error.
When IO is heavily loaded, the impact of IO schedulers on App launch
time varies. To measure the impact, added io_stress and io_scheduler two
parameters and related jinja2 blocks.

Juno's bootargs parameter specifies the kernel boot arguments as a
sigle string. However, when it is passed into _boot_via_uboot, it was
expanded as a mapping, causing an error. This fixes that boneheaded
mistake...
As of Android 6.0, apps can request permissions at runtime. If the
target device is running Android 6.0+ these permissions are now automatically
granted.
- Summary metrics are now calculated from the contents of energy.csv and
added to the overall results.
- Added a new "strict" parameter. If this is set to False, the device
check during validation is omitted.
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.
If the value of a classifier was zero (or any other value that
interprets as boolean False), it used to be coverted to an empty entry.
This makes sure that the value gets correctly ropagated.
Previously swipe_to_unlock was not used and conflicted with a method
of the same name.
- swipe_to_unlock() renamed perform_unlock_swipe()
- swipe_to_unlock parameter now takes a direction, this allows swipe unlocking on Android M devices
- ensure_screen_is_on() will now also unlock the screen if swipe_to_unlock is set
- 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.
Added two parameters which allow the user to change the strings used
to match the login prompt and the following password prompt to match
their device configurations.
Adjust the wait_for_boot method of Gem5AndroidDevice to no longer wait
for the boot animation to finish if the animation has been
disabled. The service.bootanim.exit property is only set (to 0) when
the animation starts, and is set to 1 when the animation finishes. If
the animation never starts, then the property is not set at
all. Hence, we assume the boot animation has finished, unless the
property has been set.
Moved the commands to resize the shell to their own method. They are
now executed twice. Once as soon as the shell is connected, and a
second time as part of initialize. This latter call takes place after
the isntallation of busybox.
This is a fix to the previous fix
(2510329cdf) that updated get_properties
to store "dumpsys window" output relative to the working_directory. That
commit constructed the path using self.device, which is wrong, as in
this case self itself is the device.
- 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.
- This patch addresses an issue with the arguments passed the
BaseGem5Device __init__. With this patch these are no longer passed
in as they are not required in the base device implementation.
- The streamline instrument can now run on linux clients
because it no longer relies on adb port forwarding
- Updated description.
- Cleaned up code
- Now check for streamline not caiman
- Gatord is now only run once instead of restarted every
job
Commit 95f17702d7 redirected output of
"dumpsys window" to a file (needed for Gem5 support). However, the file
was created in $PWD, which breaks on production devices, as that
location is not writable. This moves the file under the working
directory on the device.
- 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.

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.

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.
