libbpf: Improve libbpf API documentation link position

2022-04-22T14:21:56Z

This puts the link for libbpf API documentation into the sidebar for much easier navigation. You can preview this change at: https://libbpf-test.readthedocs.io/en/latest/ Note that the link is hardcoded to the production version, so you can see that it self references itself here for now: https://libbpf-test.readthedocs.io/en/latest/api.html This will need to make its way into the libbpf mirror, before being deployed to libbpf.readthedocs.org Signed-off-by: Grant Seltzer Signed-off-by: Daniel Borkmann Link: https://lore.kernel.org/bpf/20220422031050.303984-1-grantseltzer@gmail.com

bpf, docs: Better document the atomic instructions

2022-02-03T17:29:37Z

Use proper tables and RST markup to document the atomic instructions in a structured way. Signed-off-by: Christoph Hellwig Signed-off-by: Alexei Starovoitov Link: https://lore.kernel.org/bpf/20220131183638.3934982-6-hch@lst.de

bpf, docs: Better document the extended instruction format

2022-02-03T17:29:37Z

In addition to the normal 64-bit instruction encoding, eBPF also has a single instruction that uses a second 64-bit bits for a second immediate value. Instead of only documenting this format deep down in the document mention it in the instruction encoding section.
