Sadly this has regressed my qemu-system-aarch64 EL2 run. It was slightly
masked by an unrelated assertion breakage which I had to fix. However
with this patch my boot hangs spinning all 4 threads. Once reverted
things work again.
My command line:
timeout -k 1s --foreground 120s ./aarch64-softmmu/qemu-system-aarch64 -machine
type=virt -display none -m 4096 -cpu cortex-a57 -serial mon:stdio -netdev user,id=unet
-device virtio-net-device,netdev=unet -drive
file=/home/alex/lsrc/qemu/images/jessie-arm64.qcow2,id=myblock,index=0,if=none -device
virtio-blk-device,drive=myblock -append "console=ttyAMA0 root=/dev/vda1
systemd.unit=benchmark.service" -kernel
/home/alex/lsrc/qemu/images/aarch64-current-linux-kernel-only.img -smp 4 -machine
gic-version=3 -machine virtualization=true -name debug-threads=on
If you ignore the timeout, does it complete eventually?
It may not be the same thing, but that pull left out the final patch for
target/alpha that enabled goto_ptr. But as I hadn't seen a similar problem
with other guests, I was assuming that the problem was in hw/alpha/, or some
other bit of the interrupt chain.
