Patch 1 is to enable cross platform testing for local vmtest. The
remaining patch adds local vmtest support for riscv64. It relies on
commit [0] [1] for better regression.
We can now perform cross platform testing for riscv64 bpf using the
following command:
PLATFORM=riscv64 CROSS_COMPILE=riscv64-linux-gnu- \
tools/testing/selftests/bpf/vmtest.sh -- \
./test_progs -d \
\"$(cat tools/testing/selftests/bpf/DENYLIST.riscv64 \
| cut -d'#' -f1 \
| sed -e 's/^[[:space:]]*//' \
-e 's/[[:space:]]*$//' \
| tr -s '\n' ','\
)\"
The test platform is x86_64 architecture, and the versions of relevant
components are as follows:
QEMU: 8.2.0
CLANG: 17.0.6 (align to BPF CI)
OpenSBI: 1.3.1 (default by QEMU)
ROOTFS: ubuntu jammy (generated by [2])

Link: https://github.com/libbpf/ci/blob/main/rootfs/mkrootfs_debian.sh [2]Hello, I wanted to do a test run for this patch-set but did not figure out how to build rootfs for riscv64 system. I modified mkrootfs_debian.sh as below, but build command fails: $ ./rootfs/mkrootfs_debian.sh -d jammy -a riscv64 -m http://de.archive.ubuntu.com/ubuntu ... E: Couldn't download http://de.archive.ubuntu.com/ubuntu/dists/jammy/main/binary-riscv64/Packages Apparently jammy does not have binaries built for riscv64, or I'm failing to find correct mirror. Could you please provide some instructions on how to prepare rootfs? Thanks, Eduard --
