be79505c - tools/runqslower: Install libbpf headers when building

Thu, 07 Oct 2021 19:44:31 +0000

tools/runqslower: Install libbpf headers when buildingAPI headers from libbpf should not be accessed directly from thelibrary's source directory. Instead, they should be exported with "makeinstall_headers". Let's make sure that runqslower installs theheaders properly when building.We use a libbpf_hdrs target to mark the logical dependency on libbpf'sheaders export for a number of object files, even though the headersshould have been exported at this time (since bpftool needs them, and isrequired to generate the skeleton or the vmlinux.h).When descending from a parent Makefile, the specific output directoriesfor building the library and exporting the headers are configurable withBPFOBJ_OUTPUT and BPF_DESTDIR, respectively. This is in addition toOUTPUT, on top of which those variables are constructed by default.Also adjust the Makefile for the BPF selftests. We pass a number ofvariables to the "make" invocation, because we want to point runqslowerto the (target) libbpf shared with other tools, instead of building itsown version. In addition, runqslower relies on (target) bpftool, and wealso want to pass the proper variables to its Makefile so that bpftoolitself reuses the same libbpf.Signed-off-by: Quentin Monnet Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20211007194438.34443-6-quentin@isovalent.com List of files: /linux-6.15/tools/bpf/runqslower/Makefile

tools/runqslower: Ensure own vmlinux.h is picked up firstReorder include paths to ensure that runqslower sources are picking upvmlinux.h, generated by runqslower's own Makefile. When runqslower is builtfrom selftests/bpf, due to current -I$(BPF_INCLUDE) -I$(OUTPUT) ordering, itmight 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 ensurevmlinux.h is properly completed before source code relying on it is compiled.
