Update the syntax of the TargetNotRespondingError to conform with the
other exceptions of expecting a full message to be displayed rather than just
a target name.
subprocess.Popen (used internally by check_output) is not thread-safe
and may cause a thread to lock up if called simultaneously from multiple
threads. See
https://bugs.python.org/issue12739
This is fixed in Python 3.2, but since we're currently still on 2.7,
work around the issue by protecting the call with a lock.
Correctly detect whether or not the energy should be calculated from
power or extracted directly. Previously both methods were being used
at the same time, resulting in incorrect total energy values.
The `-e` argument to match logcat output with a regex expression is not
present on older devices. If the target is running pre marshmallow fall
back to pipeing logcat into grep.
gem5 prints a string, to communicate which telnet port can be used to connect
to the gem5 system. The exact string has recently changed. This commit ensures
both the old and new string are taken into account when devlib parses gem5
output to determine the telnet port.
Add an empty implementation, as there is currently no generic way of
detecting boot completion for a random Linux system, and it is
considered to be "fully booted" as soon as it ready to accept
connections.
Previously, commit
commit 17bcabd461b22434db00552056e7de995fc7f498
target: Install busybox before updating modules
moved busybox deployment into Target.connect() so that modules could
make use of it. This means this now happens before AndroidTarget waits
for the boot to complete at the end of its connect(). This means that
an attempt to create the devlib working directory may be made too early.
To get around this, move wait_boot_completed() into Target, and ensure
it returns before attempting to create the working directory.
SerialError does not populate it's message attribute, so the message was
lost when re-raising as HostError. Pass the string representation of
SerialError into HostError instead.
- The autoboot message in the firmware has changed; detect both the old
and the new messages.
- Depending on where exactly the boot was interrupted, either a "reboot"
or a "reset" may be required; so send both.
In recent builds, it seems doing "ip addr list eth0" returns "no such
device" when running as a regular user. Doing so as root, will give the
information on the device.
The stderr of a command is not propagated as part of the command
output. However, some workloads/commands write vital output to
stderr. For this reason, we add an option to invoke which redirects
stderr to stdout (redirect_stderr). This is disabled by default.
The tasks() function allows to get the tasks that are in a cgroup.
Filters for the tasks TID, name and cmdline have been added to the
parameters of the function such that it is possible to select the tasks
that match these patterns.

Previously, when the gem5 simulation crashed, one would get errors
relating to pexpect reaching EOF, rather than an informative message
stating the gem5 itself had crashed. With this change, we catch some
of the common cases where this can happen, and inform the user if gem5
itself has crashed. In the event that the gem5 simulation itself has
not reported an error, we instead re-throw the original pexpect error.
Add new energy instrument that is based on arm-probe tool to manage AEP
Main advantages of this tool are:
- uses a config file for describing channels and shunt resistors value
- manages power topology description in the config file. This topology
is then used when computing power figures
- can create virtual power channel and aggregate channels
- support multiple AEP
- support auto-zero of AEP's channel

Some targets don't seem to set system.user_rotation, resulting in "null"
being returned. This exploded on integer conversion. Handle this case by
returning the Python equivalent, None.
Adds initial support for ChromeOs Targets.
If the device does not support running android apps the target will
behave like a `LinuxTarget` however if android is supported, the chromeos
target opens 2 connections, one via shh to the linux target, as normal,
and one via adb to the android container. By default all calls will be
made to the linux target and if not present, will attempt to use the
android container instead. The android container is also exposed via a
`android_container` attribute so can be accessed directly.
In order to detect whether the target supports running android apps the
existance of '/opt/google/containers/android/' will be queried upon
connection to the linux target.
Since:
cafc0a4 target: do not create shutil in package directory
we generate 'shutils' in /tmp, which is also the executables_path
used by default by a LocalLinuxTarget.
This ultimately results into a:
self.install(shutils_ofile)
...
shutil.copy(source, dest)
raising an exception since source == dest.
Let's fix this by setting /tmp/devlib-target as a default base path for
all devlib deployed stuff into a localhost target.

Do not attempt to create shutil from shutil.in inside
PACKAGE_BIN_DIRECTORY as that may not be writable. Instead, create it in
the temporary directory and remove it right after installing.
Since 1e34390b990f1d85b083d31693d71fad5c9f28a6, AndroidTarget and
LinuxTarget share the same code for `push` and `pull`. However,
these methods expect a `_file_transfer_cache` field to be present.
It is currently populated in `_resolve_paths` for AndroidTarget
and LinuxTarget, but not for LocalLinuxTarget.
Since LocalLinuxTarget inherits its `push` & `pull` from LinuxTarget,
this causes an exception. This commit fixes it by adding an assignment
to `_file_transfer_cache` in `LocalLinuxTarget:_resolves_paths`.
This is a simple fix, and the actual push/pull behaviour of that local
target class could be improved in regards to that transfer cache, but
it should be good enough for now.
Previously the root directory was used when checking for device
connection, on some devices this requires elevated permissions so now
use '/data/local/tmp' which should not have permission restrictions.
