The old way of keeping track of the filenames for the patches that correspond to the commits was to add a special comment line to the end of the commit message, e.g., "%% original patch: <filename>", using a temporary git hook. This method had some drawbacks, e.g.: * It caused problems if one wanted to push the commits upstream as the comment line had to be manually removed. * The comment line would end up in patches if someone used git format-path rather than devtool finish to generate the patches. * The comment line could interfere with global Git hooks used to validate the format of the Git commit message. * When regenerating patches with `devtool finish --force-patch-refresh`, the process typically resulted in adding empty lines to the end of the commit messages in the updated patches. A better way of keeping track of the patch filenames is to use Git notes. This way the commit messages remain unaffected, but the information is still shown when, e.g., doing `git log`. A special Git notes space, refs/notes/devtool, is used to not intefere with the default Git notes. It is configured to be shown in, e.g., `git log` and to survive rewrites (i.e., `git commit --amend` and `git rebase`). Since there is no longer any need for a temporary Git hook, the code that manipulated the .git/hooks directory has also been removed. To avoid potential problems due to global Git hooks, --no-verify was added to the `git commit` command. To not cause troubles for those who have done `devtool modify` for a recipe with the old solution and then do `devtool finish` with the new solution, the code will fall back to look for the old strings in the commit message if no Git note can be found. While not technically motivated like above, the way to keep track of ignored commits is also changed to use Git notes to avoid having different methods to store similar information.

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.

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.
