Peter Marko 2f808c92cc bitbake: doc/bitbake-user-manual-ref-variables: update BB_TASK_IONICE_LEVEL
Provided example does not work due to two problems.

CFQ scheduler was removed in kernel 4.20 (per [1])
Replace it with BFQ scheduler.

Also fix typo "queu" -> "queue".

Documentation

This is the directory that contains the BitBake documentation.

Manual Organization

Folders exist for individual manuals as follows:

  • bitbake-user-manual --- The BitBake User Manual

Each folder is self-contained regarding content and figures.

If you want to find HTML versions of the BitBake manuals on the web, go to https://www.openembedded.org/wiki/Documentation.

Sphinx

The BitBake documentation was migrated from the original DocBook format to Sphinx based documentation for the Yocto Project 3.2 release.

Additional information related to the Sphinx migration, and guidelines for developers willing to contribute to the BitBake documentation can be found in the Yocto Project Documentation README file:

https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/tree/documentation/README

How to build the Yocto Project documentation

Sphinx is written in Python. While it might work with Python2, for obvious reasons, we will only support building the BitBake documentation with Python3.

Sphinx might be available in your Linux distro packages repositories, however it is not recommend using distro packages, as they might be old versions, especially if you are using an LTS version of your distro. The recommended method to install Sphinx and all required dependencies is to use the Python Package Index (pip).

To install all required packages run:

$ pip3 install sphinx sphinx_rtd_theme pyyaml

To build the documentation locally, run:

$ cd doc $ make html

The resulting HTML index page will be _build/html/index.html, and you can browse your own copy of the locally generated documentation with your browser.
