From 9c01546d26d28cf57341d8380ba900bf68e26b18 Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Sun, 12 Jan 2020 23:31:42 -0800 Subject: tools/bpf: Add runqslower tool to tools/bpf Convert one of BCC tools (runqslower [0]) to BPF CO-RE + libbpf. It matches its BCC-based counterpart 1-to-1, supporting all the same parameters and functionality. runqslower tool utilizes BPF skeleton, auto-generated from BPF object file, as well as memory-mapped interface to global (read-only, in this case) data. Its Makefile also ensures auto-generation of "relocatable" vmlinux.h, which is necessary for BTF-typed raw tracepoints with direct memory access.
