HabrEmbedded Linux для начинающих (Часть вторая)В первой статье мы разобрались с базовыми терминами: что такое Embedded Linux, чем он отличается от обычного дистрибутива, из чего состоит, как происходит его загрузка и с помощью каких инструментов всё это можно собрать. Надеюсь, что те, кого эта тема зацепила, уже обзавелись платой с SoC на борту — без неё часть шагов будет упущена, а удовольствие от результата будет неполным. Пришло время перейти от теории к практике!<a href="https://habr.com/ru/articles/925804/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/articles/925804/</a><a href="https://zhub.link/tags/buildroot" class="mention hashtag" rel="nofollow noopener" target="_blank">#buildroot</a> <a href="https://zhub.link/tags/embedded_linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#embedded_linux</a> <a href="https://zhub.link/tags/soc" class="mention hashtag" rel="nofollow noopener" target="_blank">#soc</a> <a href="https://zhub.link/tags/%D0%BE%D0%B1%D1%83%D1%87%D0%B0%D1%8E%D1%89%D0%B8%D0%B9_%D0%BC%D0%B0%D1%82%D0%B5%D1%80%D0%B8%D0%B0%D0%BB" class="mention hashtag" rel="nofollow noopener" target="_blank">#обучающий_материал</a>

Jarkko Sakkinenfixing up the sort algorithm mess, adding compile time option for sysfs scan (for e.g., supporting some Buildroot configurations) and perhaps --json and lsiommu should be good enough for 1.0.

HabrEmbedded Linux для начинающих (Часть первая)Однажды по работе мне прилетела задача по сборке и запуску Linux на одноплатном ПК. Тогда я, будучи разработчиком ПО для микроконтроллеров, встал в небольшой ступор — задачка явно не решалась установкой IDE и нажатием в ней кнопки «Собрать проект». Гугл помог узнать о том, что существует некий Buildroot. В материалах по теме всё выглядело довольно просто: скачай, настрой, дерни пару команд, загрузи результат на одноплатник — и можно запускать! Получается, процесс не многим сложнее установки дистрибутива Linux или Windows на обычный ПК? Конечно же, нет. Ведь если у тебя в руках кастомный одноплатник неизвестного китайского бренда, а не BeagleBone или Raspberry Pi, то зарыться в Buildroot придётся с головой...<a href="https://habr.com/ru/articles/924624/" rel="nofollow noopener" translate="no" target="_blank">https://habr.com/ru/articles/924624/</a><a href="https://zhub.link/tags/buildroot" class="mention hashtag" rel="nofollow noopener" target="_blank">#buildroot</a> <a href="https://zhub.link/tags/embedded_linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#embedded_linux</a> <a href="https://zhub.link/tags/soc" class="mention hashtag" rel="nofollow noopener" target="_blank">#soc</a> <a href="https://zhub.link/tags/%D0%BE%D0%B1%D1%83%D1%87%D0%B0%D1%8E%D1%89%D0%B8%D0%B9_%D0%BC%D0%B0%D1%82%D0%B5%D1%80%D0%B8%D0%B0%D0%BB" class="mention hashtag" rel="nofollow noopener" target="_blank">#обучающий_материал</a>

Fiona<a href="https://woem.men/tags/Python" rel="nofollow noopener" target="_blank">#Python</a> package management question: Is there some way to have <code>pip</code> (and tools using it, e.g. Nox/Tox) use local sources and ideally distro installs, and only download from PyPI after explicit confirmation? I'm well aware of venv etc., my point is about the <code>pip</code> calls to set those up. Ideally, what I'd want <code>pip</code> to do to resolve a package, in order: 1. Check a list of locally configured source directories. As in, if I have the repository for package A, I add that directory to a list/mapping, and then A always gets installed from the source as present there, or a specific tag. 2. Use the package as installed by my distro. This is similar to <code>pipx install --system-site-packages</code>, but I'd only want the explicitly installed packages available in the venv (or <code>pipx</code> install, etc.), not all, so tests can confirm that the dependencies listed in <code>pyproject.toml</code> are actually complete. 3. Use a local cache of PyPI (and optionally other sources) packages. 4. Fetch to/update cache only after explicit approval. <code>index-url</code> or <code>find-links</code> don't cover this, because they require pre-built sdist/wheel packages. I want to be able to work offline as far as possible, and keep track of the exact sources I'm using. Partially inspired by <a href="https://woem.men/tags/Buildroot" rel="nofollow noopener" target="_blank">#Buildroot</a>, which gives me an archive of all sources used in my firmware build as part of the concept. As far as I see it now, if I really want this without heavily patching <code>pip</code>, my only option would be to implement all this as something that provides a web interface I can use as <code>index-url</code>, and I'm not excited about that idea. :neocat_laugh_sweat:

Jarkko SakkinenI wonder if a kselftest written with Python can depend on GStreamer? I.e. check and skip on failure. I'm almost done converting the demo shown in my screencast from bash and fmpeg to python and gstreamer [1]. There has been bunch of blockers, like for example getting Python bindings compile in my BuildRoot environment (stable version bump helped). One final peace that I was missing was how to pass a file descriptor to GStreamer pipeline but here it is: <a href="https://gstreamer.freedesktop.org/documentation/coreelements/fdsrc.html" rel="nofollow noopener" target="_blank">https://gstreamer.freedesktop.org/documentation/coreelements/fdsrc.html</a> So... 1.5 weeks of scratching my head but this all work was absolutely required before making the breaking API change to the driver code (i.e. return file descriptor to an anoymous inode in the ioctl instead of writing to /dev/video0). Now I need only a small tweak to the test program when I test that kernel change. FINALLY ready to go back to the fun i.e. kernel hacking ;-) [1] <a href="https://social.kernel.org/notice/ApXBpAVuAyGBmcPye8" rel="nofollow noopener" target="_blank">https://social.kernel.org/notice/ApXBpAVuAyGBmcPye8</a> <a class="hashtag" href="https://social.kernel.org/tag/linux" rel="nofollow noopener" target="_blank">#linux</a> <a class="hashtag" href="https://social.kernel.org/tag/kernel" rel="nofollow noopener" target="_blank">#kernel</a> <a class="hashtag" href="https://social.kernel.org/tag/gstreamer" rel="nofollow noopener" target="_blank">#gstreamer</a> <a class="hashtag" href="https://social.kernel.org/tag/python" rel="nofollow noopener" target="_blank">#python</a> <a class="hashtag" href="https://social.kernel.org/tag/buildroot" rel="nofollow noopener" target="_blank">#buildroot</a>
