Subject: [PATCH v3 3/4] selftests: kho: Add riscv support
Date: Fri,  6 Nov 2026 15:14:58 +0800	[thread overview]
Message-ID: <20261106071459.2003-4-cp0613@linux.alibaba.com> (raw)
In-Reply-To: <20261106071459.2003-1-cp0613@linux.alibaba.com>

Describe the machine the KHO vmtest runner needs to boot riscv64, so the
test stops being skipped on this architecture.

Signed-off-by: Chen Pei <cp0613@linux.alibaba.com>

Test: qemu-system-riscv64 (virt, -cpu max, TCG), in-tree runner
"tools/testing/selftests/kho/vmtest.sh -t riscv64" (boots the Image
and kexec'es into the same Image).

  KHO: found kexec handover data.
  test_kho: KHO restore succeeded
  ok 1 KHO succeeded
  # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0
