runqslower doesn't specify include path for uapi/bpf.h. This causes the following warning: In file included from runqslower.c:10: .../tools/testing/selftests/bpf/tools/include/bpf/bpf.h:234:38: warning: 'enum bpf_stats_type' declared inside parameter list will not be visible outside of this definition or declaration 234 | LIBBPF_API int bpf_enable_stats(enum bpf_stats_type type); Fix this by adding -I tools/includ/uapi to the Makefile.

Reorder include paths to ensure that runqslower sources are picking up vmlinux.h, generated by runqslower's own Makefile. When runqslower is built from selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, it might pick up not-yet-complete vmlinux.h, generated by selftests Makefile, which could lead to compilation errors like [0]. So ensure that -I$(OUTPUT) goes first and rely on runqslower's Makefile own dependency chain to ensure vmlinux.h is properly completed before source code relying on it is compiled.

Add missing dependency of $(BPFOBJ) to $(LIBBPF_SRC), so that running make in runqslower/ will rebuild libbpf.a when there is change in libbpf/.

Fix undefined reference linker errors when building runqslower with gcc 7.4.0 on Ubuntu 18.04. The issue is with misplaced -lelf, -lz options in Makefile: $(Q)$(CC) $(CFLAGS) -lelf -lz $^ -o $@ -lelf, -lz options should follow the list of target dependencies: $(Q)$(CC) $(CFLAGS) $^ -lelf -lz -o $@ or after substitution cc -g -Wall runqslower.o libbpf.a -lelf -lz -o runqslower The current order of gcc params causes failure in libelf symbols resolution, e.g. undefined reference to `elf_memory' Fixes: 9c01546d ("tools/bpf: Add runqslower tool to tools/bpf") Signed-off-by: NJulia Kartseva <hex@fb.com> Signed-off-by: NAlexei Starovoitov <ast@kernel.org> Acked-by: NAndrii Nakryiko <andriin@fb.com> Link: https://lore.kernel.org/bpf/908498f794661c44dca54da9e09dc0c382df6fcb.1580425879.git.hex@fb.com

tools/testing/selftests/bpf/Makefile supports overriding clang, llc and other tools so that custom ones can be used instead of those from PATH. It's convinient and heavily used by some users.

Fix the runqslower tool to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To not break the build, keep the old include path until everything has been changed to the new one; a subsequent patch will remove that.

The runqslower tool refuses to build without a file to read vmlinux BTF from. The build fails with an error message to override the location by setting the VMLINUX_BTF variable if autodetection fails. However, the Makefile doesn't actually work with that override - the error message is still emitted. Fix this by including the value of VMLINUX_BTF in the expansion, and only emitting the error message if the *result* is empty. Also permit running 'make clean' even though no VMLINUX_BTF is set.

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.
