This is essential for utilizing BPF on Android (arm64), as the compilation server is running on Ubuntu (x86). Following previous guidance from V1, the two changes are as follow: V2: - patch 2: - [1/2] In Makefile, use $(SRCARCH) to get target arch's uapi. Therefore, there is no longer a need to compile "make headers_install". - [2/2] Regard "LDLIBS += -lzstd" as a separate patch for static compile. v1: Link: https://lore.kernel.org/bpf/20240827133959.1269178-1-yikai.lin@vivo.com/ - patch 2: - [1/2] Update "vmtest.sh" for cross-compile arm64 on x86_64 host. - [2/2] Fix cross-compile issue for some files and a static compile issue for "-lzstd" Lin Yikai (2): selftests/bpf: Enable vmtest for cross-compile arm64 on x86_64 host, and fix some related issues. selftests/bpf: fix static cross-compile error for liblstd.a linking. tools/testing/selftests/bpf/Makefile | 8 +++++- tools/testing/selftests/bpf/README.rst | 11 +++++++- tools/testing/selftests/bpf/vmtest.sh | 37 +++++++++++++++++++++----- 3 files changed, 48 insertions(+), 8 deletions(-)
