Jakub Kicinski says: ==================== This series started out as a follow up to the bpftool perf event dumping patches. As suggested by Daniel patch 1 makes use of PERF_SAMPLE_TIME to simplify code and improve accuracy of timestamps. Remaining patches are trying to move perf event loop into libbpf as suggested by Alexei. One user for this new function is bpftool which links with libbpf nicely, the other, unfortunately, is in samples/bpf. Remaining patches make samples/bpf link against full libbpf.a (not just a handful of objects). Once we have full power of libbpf at our disposal we can convert some of XDP samples to use libbpf loader instead of bpf_load.c. My understanding is that this is the desired direction, at least for networking code. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
