The latency or time-delay between XDP and AF_XDP depend highly on whether the XDP and AF_XDP runs on same CPU or remote CPU. Extend xdp_hints_rx_time, without worrying about the layout as BTF will adjust, so we can determine case of same CPU or remote CPU. Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com>
Practical BPF examples
This git repository contains a diverse set of practical BPF examples that solve (or demonstrate) a specific use-case using BPF.
It is meant to ease doing rapid prototyping and development, writing C-code BPF programs using libbpf. The goal is to make it easier for developers to get started coding.
Many developers struggle to get a working BPF build environment. The repo enviroment makes it easy to build/compile BPF programs by doing the necessary libbpf setup transparently and detect missing compile dependencies (via the configure script). It is a declared goal to make BPF programming more consumable by detecting and reporting issues (when possible).
