It's a follow-up for discussion in [1]. drgn tool bpf_inspect.py was merged to drgn repo in [2]. Document it in kernel tree to make BPF developers aware that the tool exists and can help with getting BPF state unavailable via UAPI. For now it's just one tool but the doc is written in a way that allows to cover more tools in the future if needed. Please refer to the doc itself for more details. The patch was tested by `make htmldocs` and sanity-checking that resulting html looks good. v2 -> v3: - two sections: "Description" and "Getting started" (Daniel); - add examples in "Getting started" section (Daniel); - add "Customization" section to show how tool can be customized. v1 -> v2: - better "BPF drgn tools" section (Alexei) [1] https://lore.kernel.org/bpf/20200228201514.GB51456@rdna-mbp/T/#mefed65e8a98116bd5d07d09a570a3eac46724951 [2] https://github.com/osandov/drgn/pull/49 Signed-off-by: Andrey Ignatov <rdna@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/bpf/20200324185135.1431038-1-rdna@fb.com |

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.
