在 QEMU-ARM 平台上启动两个nimbos，并分别注入 timer 中断

Clone代码

新建创建项目的clone.sh，然后bash clone.sh自动创建项目

#!/bin/bash

BRANCH="-b debin/2vm_timer"

mkdir -p crates

git clone $BRANCH https://github.com/arceos-hypervisor/arceos-umhv.git 

cd arceos-umhv

# 克隆arceos主仓库
git clone $BRANCH https://github.com/arceos-hypervisor/arceos.git ../arceos

# 克隆其他仓库到crates目录
REPOS=(
    "axvm"
    "axvcpu"
    "axaddrspace"
    "arm_vcpu"
    "axdevice"
    "arm_vgic"
    "arm_gicv2"
    "axdevice_crates"
)

for repo in "${REPOS[@]}"; do
    git clone $BRANCH "https://github.com/arceos-hypervisor/${repo}.git" "../crates/${repo}"
done

echo "所有仓库克隆完成！"

# 创建临时文件
temp_file=$(mktemp)

编译nimbos

因为加载到任意地址的功能还没有实现，所以只能通过硬配置来做，得单独编译两个nimbos

nimbos（VM1）

git clone https://github.com/arceos-hypervisor/nimbos.git

nimbos（VM2）

git clone -b debin/0x800 https://github.com/arceos-hypervisor/nimbos.git

创建`disk.img`文件

生成一个disk.img，然后将编译好的nimbos.bin重命名并放入里面

cd arceos-umhv/arceos-vmm/
mkdir mnt
make disk_img
sudo mount disk_img mnt
cp nimbos_0x408_0000.bin ./mnt
cp nimbos_0x808_0000.bin ./mnt
cd .. && sudo umount mnt

启动VMMS

cd arceos-umhv/arceos-vmm/
bash run.sh

# 在qemu启动后，打开第二个终端使用telnet连接串口2
telnet localhost 4321

就可以正常注入timer了

多虚拟串口支持

如果不能正常启动，考虑使用修改版的qemu

git clone https://github.com/luodeb/qemu.git
./configure --enable-slirp --target-list=aarch64-softmmu,aarch64-linux-user --prefix=/path/to/qemu-9.2.0
make -j
make install

串口	地址	中断号offset
UART0	0x09000000	1
UART1	0x09040000	8
UART2	0x09100000	21
UART3	0x09140000	22
