新编译出来的版本 qemu 已经支持树莓派4，可以对比一下

这是之前的 
root@iZ2ze7ajbjlxlzqf7yrk1zZ:~/Github/Chenlong/qemu-patch-raspberry4/build# qemu-system-aarch64 -M help | grep ras
raspi0               Raspberry Pi Zero (revision 1.2)
raspi1ap             Raspberry Pi A+ (revision 1.1)
raspi2b              Raspberry Pi 2B (revision 1.1)
raspi3ap             Raspberry Pi 3A+ (revision 1.0)
raspi3b              Raspberry Pi 3B (revision 1.2)

下面是新编译出的（执行需要用 ./qemu-system-aarch64 指定当前目录下执行)

root@iZ2ze7ajbjlxlzqf7yrk1zZ:~/Github/Chenlong/qemu-patch-raspberry4/build# ./qemu-system-aarch64 -M help | grep ras

初步尝试了一下用 -machine raspi4b2g 来运行 A=apps/helloworld ，结果 qemu 执行时卡住，没有看到任何输出

编译 arceos 命令行
# make A=apps/helloworld ARCH=aarch64 PLATFORM=aarch64-raspi4 LOG=debug SMP=4 run

最后执行模拟器的命令行
# qemu-system-aarch64 -m 2G -smp 4 -cpu cortex-a72 -machine raspi4b2g -kernel apps/helloworld/helloworld_raspi4-aarch64.bin -nographic

其间遇到了有2个报错，说明如下：

新 qemu 要求 树莓派4 内存 RAM 是 2G
# qemu-system-aarch64 -m 128M -smp 4 -cpu cortex-a72 -machine raspi4b2g -kernel apps/helloworld/helloworld_raspi4-aarch64.bin -nographic 
qemu-system-aarch64: Invalid RAM size, should be 2 GiB

新 qemu 要求 树莓派4 CPUs 是 4 个
# qemu-system-aarch64 -m 2G -smp 1 -cpu cortex-a72 -machine raspi4b2g -kernel apps/helloworld/helloworld_raspi4-aarch64.bin -nographic 
qemu-system-aarch64: Invalid SMP CPUs 1. The min CPUs supported by machine 'raspi4b2g' is 4

所以最终 qemu 运行时的参数为

-m 2G -smp 4 -cpu cortex-a72 -machine raspi4b2g

执行时没有任何输出的原因，还没有找到。可能是 qemu 不能直接运行 arceos ，需要先运行树莓派自己的 bootcode.bin 才行？

helloworld_aarch64-raspi4.bin 在 qemu 模拟器里跑通了！😄

之前问题的原因也找到了，因为好几个版本（不同开发者）的 arceos 库都叫 arceos，没有用最新的贾越凯的库，用了早期的齐呈祥的 arceos 库。

参考下面在 virt 上正确运行的参数，增加了 -device virtio-blk-device,drive=disk0 -drive id=disk0,if=none,format=raw,file=disk.img ，
仍然报错 No 'virtio-bus' bus found for device 'virtio-blk-device' ，
怀疑是指定了 -machine raspi4b2g 导致 qemu 不再支持 virtio-bus 造成的。

搞定了！😄 需要增加2个编译参数：
BLK=y
FEATURES=driver-ramdisk

# make A=apps/fs/shell ARCH=aarch64 PLATFORM=aarch64-raspi4  LOG=debug BLK=y FEATURES=driver-ramdisk
