Subject: [PATCH bpf-next v2 3/4] selftests/bpf: Update qemu config for riscv64 in vmtest.sh
Date: Wed, 30 Sep 2026 06:46:06 +0000 [thread overview]
Message-ID: <20260930064607.1908864-4-pulehui@huaweicloud.com> (raw)
In-Reply-To: <20260930064607.1908864-1-pulehui@huaweicloud.com>
From: Pu Lehui <pulehui@huawei.com>
When running vmtest.sh on riscv64, the kernel panic at boot due to an
illegal instruction. This is because '-cpu rv64' only enables a baseline
set of riscv extensions, whereas the kernel or toolchain requires newer
extensions. Switch to '-cpu max' so qemu enables all supported
extensions.
Additionally, qemu's pmu emulation for riscv64 currently has issues,
causing perf_event_open-related tests to fail. Temporarily disable the
sscofpmf extension to bypass these failures for now, and will try to
investigate and address it later.
While at it, update the libbpf/ci branch in INDEX_URL from 'master' to
'main'.
