QEMU: Terminated
[ Test Plan ]
To reproduce the issue:
Run RISC-V virtual machine as described in
https://wiki.ubuntu.com/RISC-V/QEMU.
sudo apt-get update
sudo apt-get install qemu-efi-riscv64 qemu-system-misc
cp /usr/share/qemu-efi-riscv64/RISCV_VIRT_*.fd .
qemu-system-riscv64 \
-M virt,acpi=off -accel tcg -m 1024 \
-nographic \
-drive if=pflash,format=raw,unit=0,file=RISCV_VIRT_CODE.fd,readonly=on \
-drive if=pflash,format=raw,unit=1,file=RISCV_VIRT_VARS.fd
# In the EFI shell
reset -s
sudo modprobe kvm
sudo qemu-system-riscv64 \
-M virt,acpi=off -accel kvm -m 1024 \
-nographic \
-drive if=pflash,format=raw,unit=0,file=RISCV_VIRT_CODE.fd,readonly=on \
-drive if=pflash,format=raw,unit=1,file=RISCV_VIRT_VARS.fd
# A crash occurs
# RISCV64 Exception Type - 0000000000000002(EXCEPT_RISCV_ILLEGAL_INST)
# Terminate emulation with <CTRL+A><x>
