* devtool: runqemu: work around runqemu script path assumptionPaul Eggleton2016-10-251-1/+6
| | | | | | | | | | | | | The new runqemu script assumes that if OECORE_NATIVE_SYSROOT is set then it shouldn't try to run bitbake to find out the values of various variables such as DEPLOY_DIR_IMAGE; this assumption is incorrect for the extensible SDK. To work around this, clear OECORE_NATIVE_SYSROOT in the environment when running runqemu. Fixes [YOCTO #10447].

* scripts: ensure tinfoil is shut down correctlyPaul Eggleton2016-09-031-3/+5
| | | | | | | | | We should always shut down tinfoil when we're finished with it, either by explicitly calling the shutdown() method or by using it as a context manager ("with ...").

* devtool: categorise and order subcommands in help outputPaul Eggleton2016-02-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The listing of subcommands in the --help output for devtool was starting to get difficult to follow, with commands appearing in no particular order (due to some being in separate modules and the order of those modules being parsed). Logically grouping the subcommands as well as being able to exercise some control over the order of the subcommands and groups would help, if we do so without losing the dynamic nature of the list (i.e. that it comes from the plugins). Argparse provides no built-in way to handle this and really, really makes it a pain to add, but with some subclassing and hacking it's now possible, and can be extended by any plugin as desired. To put a subcommand into a group, all you need to do is specify a group= parameter in the call to subparsers.add_parser(). you can also specify an order= parameter to make the subcommand sort higher or lower in the list (higher order numbers appear first, so use negative numbers to force items to the end if that's what you want). To add a new group, use subparsers.add_subparser_group(), supplying the name, description and optionally an order number for the group itself (again, higher numbers appear first).

* devtool: runqemu: avoid recipe parsePaul Eggleton2015-09-231-1/+1
| | | | | | | | We only need the base configuration to get the variable values we want to get here, there's no need to parse recipes / load the cache. Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* devtool: second fix for running from a different directoryMarkus Lehtonen2015-09-231-1/+1
| | | | | | | | | | | | | | | | Do not change change current working directory permanently, but, only for the duration of tinfoil initialization instead. The previous fix caused very unintuitive behavior where using relative paths were solved with respect to the builddir instead of the current working directory. E.g. calling "devtool extract zlib ./zlib" would always create create srctree in ${TOPDIR}/zlib, independent of the users cwd.

* devtool: add basic means of running runqemu within the extensible SDKPaul Eggleton2015-09-221-0/+64
We ship the runqemu script and if we build QEMU itself within the extensible SDK, then it would be nice to be able to run it. This is a very thin wrapper around runqemu, supplying the machine and image name so the user doesn't need to. (This subcommand is only available within the extensible SDK since it only really makes sense there where it is otherwise hard to run runqemu directly.) Implements [YOCTO #6657].
