Subject: [PATCH bpf-next v3 03/11] selftests: Pass VMLINUX_BTF to runqslower Makefile
Date: Thu, 16 Jan 2020 14:22:15 +0100
Message-ID: <157918093501.1357254.2594464485570114583.stgit@toke.dk> (raw)
In-Reply-To: <157918093154.1357254.7616059374996162336.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. Because of the previous changes to the runqslower
Makefile, if no locally-built vmlinux file exists, the wildcard search will
fall back to the pre-defined paths (and error out if they don't exist).

Fixes: 3a0d3092a4ed ("selftests/bpf: Build runqslower from selftests")
