The patch implements Rust testing framework similar to other selftest, specifically the gcc selftest in OE. It uses the client and server based method to test the binaries for cross-target on the image. The test framework is a wrapper around the Rust build system as ./x.py test. It tests many functionalities of Rust distribution like tools, documentation, libraries, packages, tools, Cargo, Crater etc. Please refer the following link for detailed description of Rust testing:- https://rustc-dev-guide.rust-lang.org/tests/intro.html#tool-tests To support the rust tests in oe-core, the following functions were added:- setup_cargo_environment(): Build bootstrap and some early stage tools. do_rust_setup_snapshot(): Install the snapshot version of rust binaries. do_configure(): To generate config.toml do_compile(): To build "remote-test-server" for qemu target image. Approximate Number of Tests Run in the Rust Testsuite :- 18000 Approximate Number of Tests that FAIL in bitbake environment :- 100-150 Normally majority of the testcases are present in major folder "test/" It contributes to more than 80% of the testcases present in Rust test framework. These tests pass as expected on any Rust versions without much fuss. The tests that fail are of less important and contribute to less than 2% of the total testcases. These minor tests are observed to work on some versions and fail on others. They have to be added, ignored or excluded for different versions as per the behavior. These tests have been ignored or excluded in the Rust selftest environment to generate success of completing the testsuite. These tests work in parallel mode even in the skipped test mode as expected. Although the patch to disable tests is large, it is very simple in that it only disables tests. When updating to a newer version of Rust, the patch can usually be ported in a day. Tested for X86, X86-64, ARM, ARM64 and MIPS64 on Ubuntu 22.04.

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.
Contribution Guidelines
The project works using a mailing list patch submission process. Patches should be sent to the mailing list for the repository the components originate from (see below). Throughout the Yocto Project, the README files in the component in question should detail where to send patches, who the maintainers are and where bugs should be reported.
A guide to submitting patches to OpenEmbedded is available at:
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
There is good documentation on how to write/format patches at:
https://www.openembedded.org/wiki/Commit_Patch_Message_Guidelines
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
