There are two important details missing from the docs: - If the memory object backing the FB already has a GEM handle, it's not re-used, a new one is generated. - Aliased planes will return the same GEM handle. v2: document how user-space can obtain DMA-BUF FDs without leaking handles (Pekka) Signed-off-by: Simon Ser <contact@emersion.fr> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Pekka Paalanen <ppaalanen@gmail.com> Cc: Daniel Stone <daniel@fooishbar.org> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230217162151.59996-1-contact@emersion.fr
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
