Waking this thread up, because I'm seeing similar behavior as Karsten -- i.e. the system hangs when launching init.Software: QEMU emulator version 4.0.50 (v4.0.0-576-g6d8e75d41c58) Linux kernel v5.2-rc1, defconfig OpenSBI commit 392749f6338a ("docs: Add documentation about dynamic firmware") Toolchain-wise: Ubuntu/Debian: riscv64-linux-gnu-gcc (Ubuntu 8.3.0-6ubuntu1) 8.3.0 Launching the VM with: ~/pkg/qemu/bin/qemu-system-riscv64 \ -nographic \ XXXX -machine virt \ -smp 2 \ -m 8G \ -object rng-random,filename=/dev/urandom,id=rng0 \ -device virtio-rng-device,rng=rng0 \ -append "console=ttyS0 selinux=0 apparmor=0 loglevel=7 rw root=/dev/vda2" \ -device virtio-blk-device,drive=hd0 \ -drive file=~/rv/play/debian-sid-sda.raw,format=raw,id=hd0 \ -device virtio-net,mac=36:8c:88:13:10:d2,netdev=network0 \ -netdev tap,id=network0,fd=3 3<>/dev/tap5 Where XXXX: -kernel ~/src/rv/opensbi/build/platform/qemu/virt/firmware/fw_jump.elf \ -device loader,file=/home/btopel/build/rv/arch/riscv/boot/Image,addr=0x80200000 \ or -kernel bbl \ # riscv-pk HEAD * When riscv-pk carries the payload, the kernel boots and succeeds to launch init. * Using OpenSBI commit 392749f6338a ("docs: Add documentation about dynamic firmware"), the kernel boots, but hangs/spins ("info registers" says it's "rdcycle"). Bisecting OpenSBI, it looks like commit 90cb4917b584 ("lib: Implement sfence.vma correctly.") broke something. At least prior that, the VM launches correctly. I haven't looked further -- any ideas?
