Subject: [PATCH bpf-next v4 03/10] selftests: Pass VMLINUX_BTF to runqslower Makefile
Date: Fri, 17 Jan 2020 14:36:40 +0100 [thread overview]
Message-ID: <157926820025.1555735.5663814379544078154.stgit@toke.dk> (raw)
In-Reply-To: <157926819690.1555735.10756593211671752826.stgit@toke.dk>
From: Toke Høiland-Jørgensen <toke@redhat.com>
Add a VMLINUX_BTF variable with the locally-built path when calling the
runqslower Makefile from selftests. This makes sure a simple 'make'
invocation in the selftests dir works even when there is no BTF information
for the running kernel. Do a wildcard expansion and include the same paths
for BTF for the running kernel as in the runqslower Makefile, to make it
possible to build selftests without having a vmlinux in the local tree.
Also fix the make invocation to use $(OUTPUT)/tools as the destination
directory instead of $(CURDIR)/tools.
Fixes: 3a0d3092a4ed ("selftests/bpf: Build runqslower from selftests")
