Update the documentation build system according to Linux v5.11-rc1. Deactive the automarkup.py extension module which on Gitlab CI is incompatible with Unicode. With this patch we can build the HTML documentation using either of Sphinx 2 and Sphinx 3. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

|
|
|
|
The ``kernel-feat`` (:py:class:`KernelFeat`) directive calls the
|
|
scripts/get_feat.pl script to parse the Kernel ABI files.
|
|
|
|
Overview of directive's argument and options.
|
|
|
|
.. code-block:: rst
|
|
|
|
.. kernel-feat:: <ABI directory location>
|
|
:debug:
|
|
|
|
The argument ``<ABI directory location>`` is required. It contains the
|
|
location of the ABI files to be parsed.
|
|
|
|
``debug``
|
|
Inserts a code-block with the *raw* reST. Sometimes it is helpful to see
|
|
what reST is generated.
