The kernel defconfig should be sufficient to trigger it. It must be the
for-kernelci branch from here:
https://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git/
My qemu command line is:
qemu-system-aarch64 \
-machine virt,gic_version=3,mte=on \
-cpu max \
-smp 2 -m 2G \
-kernel </path/to/Image> \
-semihosting -nographic \
-serial mon:stdio \
-monitor tcp:0.0.0.0:4000,server,nowait \
-netdev user,id=net0,hostfwd=tcp:0.0.0.0:4022-:22 \
-device virtio-net-device,netdev=net0 \
-object rng-random,filename=/dev/urandom,id=rng0 \
-device virtio-rng-pci,rng=rng0 \
-append 'console=ttyAMA0 earlycon=pl011,0x9000000 loglevel=9 ip=dhcp root=/dev/nfs rw nfsroot=<ip-addr>:/srv/nfs/debian-arm64,tcp,v4 kasan.mode=sync'
You don't need a filesystem, it fails before reaching that point. I
guess all it matters is '-cpu max'.
Thanks.
