让 xv6-riscv 上的 qemu 卡在 qemu-system-riscv64 ... 命令

Question

在 Ubuntu 20.04，我使用页面 Tools Used in 6.828

安装了 xv6 项目

$ sudo apt-get install git build-essential gdb-multiarch qemu-system-misc gcc-riscv64-linux-gnu binutils-riscv64-linux-gnu

他们在网页上查看的文件版本是

$ riscv64-unknown-elf-gcc --version 
riscv64-unknown-elf-gcc () 9.3.0

$ qemu-system-riscv64 --version
QEMU emulator version 5.2.50 (v5.2.0-2349-g51db2d7cf2)
Copyright (c) 2003-2020 Fabrice Bellard and the QEMU Project developers

在 xv6-riscv 上

$ make qemu
# ... lots of output ...
qemu-system-riscv64 -machine virt -bios none -kernel kernel/kernel -m 128M -smp 3 -nographic -drive file=fs.img,if=none,format=raw,id=x0 -device virtio-blk-device,drive=x0,bus=virtio-mmio-bus.0

程序卡在那里。虚拟机未启动且未显示任何提示。

欢迎提出任何解决此问题的想法。

Answer 1

这已在 Tools Used in 6.S081

中提到

At this moment in time, it seems that the package qemu-system-misc has received an update that breaks its compatibility with our kernel. If you run make qemu and the script appears to hang after
qemu-system-riscv64 -machine virt -bios none -kernel kernel/kernel -m 128M -smp 3 
nographic -drive file=fs.img,if=none,format=raw,id=x0 -device virtio-blk
device,drive=x0,bus=virtio-mmio-bus.0
you'll need to uninstall that package and install an older version:
$ sudo apt-get remove qemu-system-misc
$ sudo apt-get install qemu-system-misc=1:4.2-3ubuntu6
