As per issue #102, not all devices have permission to list the root directory
causing the ls command to be incorrectly determined. This commit changes the
directory to be checked to the working directory to ensure sufficient
permissions.
This means when caiman is broken you can see the error message, instead of just
finding out later that there is no data.
We still don't detect caiman being broken until we call stop(), but it's still
an improvement.
Fixes issue #98 where the passed `cpus` parameter was ignored when setting the
governor and frequency and set for all cpus instead of those specified in the
passed parameter.
Also fixes kwargs not being correctly passed for governor tunables.
CFLAGS in the makefile were being specified incorrectly.
- the single quotes for forcing all options to be passed as a single
token by the shell.
- Specifying -static and -lc via -Wl is not needed.
If the ADB command fails (e.g. if you provide the wrong device ID), adb_command
raises a CalledProcessError. CalledProcessError doesn't print the output of the
failed command, so you get a useless error message.
This is relevent here in particular as _setup_ls is the first thing to run an
ADB command if a non-IP device ID is provided.
Catch the CalledProcessError and instead raise a HostError with the command
output in the exception message.
From #92, when rebooting a platform the internal connection state becomes
different from `_connected_as_root`, now clears the state upon device reboot or
reset.
Gem5SimulationPlatfrom was not acceping base Platform's parameters, such
as core_names, making it impossible to configure them on construction.
This is rectified in this commit.
When rebooting a platform the internal connection state becomes
different from _connected_as_root, which was set before reboot.
Add the possibility to force adb root if you've rebooted or know
to have done something that would result in the platform having
a different connection state than the one of _connected_as_root.

Commit 28891a82 made it easier to debug issues during walk_modules by
attaching the specific name of the module being loaded to the exception.
However, the error may not originite in the imported module, but one of
the modules that module itself is importing.
To further facilitate debugging, exc_info (which contains the traceback)
for the orginal ImportError is now also attached to the raised
HostError.
This regex currently matches the `rc` group against the added-patches-count,
e.g. "00005" in "4.4.41-00005-g17b74bafccbe-dirty" and "59" in
"4.4.0-59-generic". Fix this by requiring "rc" in the match.
This adds a regexp to better parse all the kernel version numbers as well
as additional (optional) fields like SHA1 and RC.
The regexp has been made generic enough to match these examples:

This adds a couple of commodity ADB commands to reboot in bootloader
mode and to restart ADB in root mode.

ADB commands always expect a device ID as first parameter, here
unfortunately we need to pass it as an optional one to avoid breaking
existing clients.

This parameter is used by the other connection classes and as of
21f40035d7 ("gem5: Small tweaks in target to allow gem5 simulations") is
passed by to the connection class constructor via expansion of
Target.connection_settings (see Target.get_connection)
Previously, if an error had occured while attempting to load a module
during walk_modules, it was propagated to the loading code. This
meant that walk_modules could, in theory, raise any exception at all,
and that it was not always possible to tell exactly where the exception
originated.
Now, all encounted errors are re-raised as HostError, which preserves
the original exception in an attribute and sets "modpath" attribute to
point to the module that originated it.
Moved TimeoutError from devlib.util.misc to devlib.exception. It was
previously defined in misc because it needed to be there when the code
was part of WA in order to prevent an import cycle. This is not
necessary in devlib, so it is moved to be with the other exception
definitions.
The m5 binary allows the user to interact with gem5 simulation (e.g. reset stats).

This commit adds a gem5 simulation platform. The platform is responsible for starting the gem5 simulation.

This is the first in a series of commits to allow for the use of gem5 as a target in devlib.
The interaction with the gem5 simulation is done by the Gem5Connection, a type of TelnetConnection.
There are two types of Gem5Connections (Linux and Android) as they differ slightly in the implementation
of some methods. Other types of connections have only been changed to make them uniform (e.g. arguments for init method)

Add exit code, command, and output to TargetError exception message when execute
fails. This brings LocalConnection into line with AdbConnection and
SshConnection.
