wget https://download.qemu.org/qemu-8.2.2.tar.xz
tar -xf qemu-8.2.2.tar.xz
cd qemu-8.2.2
./configure --disable-kvm --disable-werror --prefix=/usr/local --target-list="riscv64-softmmu"
make
sudo make install
cd ..
拉取xv6源码
git clone git://g.csail.mit.edu/xv6-labs-2024
cd xv6-labs-2024
git checkout util
//util是lab1实验分支
然后：
make
make qemu
此时如果出现
xv6 kernel is booting
hart 1 starting
hart 2 starting
init: starting sh
$
则说明成功了。
那么还需要进一步验证
检查工具链：
riscv64-unknown-elf-gcc --version
检查调试工具(xv6源码目录下)：
一个终端输入：
make qemu-gdb
sed "s/:1234/:26000/" < .gdbinit.tmpl-riscv > .gdbinit
*** Now run 'gdb' in another window.
