Re: [PATCH bpf-next v1 1/2] selftests/bpf: Update "vmtest.sh" for cross-compile arm64 on x86_64 host.

Identify "$CROSS_COMPILE" to enable vm_test for cross-compile situation. Additionally, use "-cpu cortex-a57" flag to accommodate the majority of QEMU CPU lists, avoiding using "-cpu host," which can cause qemu_system_aarch64 start failure on x86_64 host.

Hi Yikai,

Your patch reminds me of a previous commit [0], which was able to support running vmtest in cross platform for all arch.
