The main communication tool in use is the Yocto Project mailing list:
Feel free to ask any kind of questions but please always prepend your email
[meta-raspberrypi] as this is the global Yocto mailing
list and not a dedicated meta-raspberrypi mailing list.
First and foremost, all of the contributions to the layer must be compliant with the standard openembedded patch guidelines:
In summary, your commit log messages should be formatted as follows:
<layer-component>: <short log/statement of what needed to be changed> (Optional pointers to external resources, such as defect tracking) The intent of your change. (Optional: if it's not clear from above, how your change resolves the issues in the first part) Signed-off-by: Your Name <email@example.com>
<layer-component> is the layer component name that your changes affect.
It is important that you choose it correctly. A simple guide for selecting a
a good component name is the following:
- For changes that affect layer recipes, please just use the base names
of the affected recipes, separated by commas (
,), as the component name. For example: use
omxplayer_git.bb. If you are adding new recipe(s), just use the new recipe(s) base name(s). An example for changes to multiple recipes would be
- For changes that affect the layer documentation, please just use
docsas the component name.
- For changes that affect other files, i.e. under the
confdirectory, please use the full path as the component name, e.g.
- For changes that affect the layer itself and do not fall into any of
the above cases, please use
meta-raspberrypias the component name.
A full example of a suitable commit log message is below:
foobar: Adjusted the foo setting in bar When using foobar on systems with less than a gigabyte of RAM common usage patterns often result in an Out-of-memory condition causing slowdowns and unexpected application termination. Low-memory systems should continue to function without running into memory-starvation conditions with minimal cost to systems with more available memory. High-memory systems will be less able to use the full extent of the system, a dynamically tunable option may be best, long-term. The foo setting in bar was decreased from X to X-50% in order to ensure we don't exhaust all system memory with foobar threads. Signed-off-by: Joe Developer <firstname.lastname@example.org>
A common issue during patch reviewing is commit log formatting, please review the above formatting guidelines carefully before sending your patches.
The preferred method to contribute to this project is to send pull requests to the GitHub mirror of the layer:
In addition, you may send patches for review to the above specified
mailing list. In this case, when creating patches using
git please make
sure to use the following formatting for the message subject:
git format-patch -s --subject-prefix='meta-raspberrypi][PATCH' origin
Then, for sending patches to the mailing list, you may use this command:
git send-email --to email@example.com <generated patch>
In order to manage and track the layer issues more efficiently, the GitHub issues facility is used by this project:
If you submit patches that have a GitHub issue associated, please make sure to
use standard GitHub keywords, e.g.
fixes, before the
“Signed-off-by” tag to close the relevant issues automatically:
foobar: Adjusted the foo setting in bar Fixes: #324 Signed-off-by: Joe Developer <firstname.lastname@example.org>
