[PATCH v2 0/3] fragments: add a 'devtool-ide-sdk' fragment

[AdrianF]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

Changes in comparison to v1:
- Drop the insecure root login part from the fragment description.
- Add support for fragments in write_config.
- Use the ide-sdk fragment in the ide_sdk selftest.

[PATCH v2 1/3] fragments: add a 'devtool-ide-sdk' fragment

[AdrianF]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

Add a configuration fragment that enables devtool ide-sdk workflow
for development and remote debugging.
The configuration is intended to streamline the development workflow
where developers can modify recipes with devtool and debug them
remotely on target devices using IDEs like VSCode.

[PATCH v2 2/3] oe-selftest: case: support fragments in write_config

[AdrianF]

From: Adrian Freihofer <adrian.freihofer@siemens.com>

When writing configuration files during selftests, also handle the
inclusion of fragment files via the toolcfg.conf mechanism.

By default the toolcfg.conf file from build/conf/toolcfg.conf is copied
to build-st/conf/toolcfg.conf. This comes with a risk for using fragments
by accident from the main build in the selftest build. To avoid this,
support writing a reproducible set of fragments per selftest case via
the write_config() method.

This should be using 'bitbake-config-build enable-fragment' rather
than write to the file directly. It should also not overwrite the
file: the 'main' build may enable important fragments for the overall
sefltest, or the machine they run on (e.g. the yocto ci is using
autobuilder fragments throughout) and they should be kept.

Hi Adrian,

Thanks for your patches.

It looks like it is breaking some test:
