仓库：

  1. rust-for-linux
  2. e1000-driver

exercise1

  1. 安装llvm
  2. 拉取仓库并配置 拉取rust-e1000分支：
git clone -b rust-e1000 https://github.com/zhang722/linux --depth=1

然后

make ARCH=arm64 LLVM=1 O=build defconfig
make ARCH=arm64 LLVM=1 O=build menuconfig

选中Rust Support和Rust Samples，搜索e1000，按数字键跳转到选项，去掉e1000驱动，然后编译

cd build
make ARCH=arm64 LLVM=1 -j8
  1. 运行截图 编译结果

exercise2

  1. 编写内核模块代码
  2. 在rust/samples下的Makefile里加入
obj-$(CONFIG_SAMPLE_RUST_HELLOWORLD)        += rust_helloworld.o
  1. 在Kconfig里加入
config SAMPLE_RUST_HELLOWORLD
	tristate "Print Helloworld in Rust"
	help
		This option builds the Rust HelloWorld module sample.
		
		To compile this as a module, choose M here:
		the module will be called rust_helloworld.
		
		If unsure, say N.
  1. 回到linux目录，重新配置
make ARCH=arm64 LLVM=1 O=build menuconfig

把Rust Samples里Print Helloworld in Rust选项勾选上，然后重新编译 5. 运行结果 加载模块

exercise3 & exercise4

  1. 编写驱动代码并编译
  2. 将驱动复制到debian文件系统镜像内
    1. 在解压的debian文件夹新建copy_ko.sh
    sudo modprobe nbd max_part=12
sudo env "PATH=$PATH" qemu-nbd --connect=/dev/nbd0 image.qcow2
sudo mount /dev/nbd0p1 /mnt/test/
sudo cp /home/zhang/workspace/rust/os/rust-for-linux/e1000-driver/src/e1000_for_linux.ko /mnt/test/e1000_for_linux.ko
sudo umount /mnt/test
sudo env "PATH=$PATH" qemu-nbd --disconnect /dev/nbd0
sudo modprobe -r nbd
    1. 在debian文件夹新建run_qemu.sh
    qemu-system-aarch64 -machine 'virt' \
    -cpu 'cortex-a57' \
    -m 1G \
    -device virtio-blk-device,drive=hd \
    -drive file=image.qcow2,if=none,id=hd \
    -device virtio-net-device,netdev=net \
    -netdev user,id=net,hostfwd=tcp::2222-:22 \
    -kernel /home/zhang/workspace/rust/os/rust-for-linux/linux/build/arch/arm64/boot/Image.gz \
    -initrd initrd -nographic -append "root=LABEL=rootfs console=ttyAMA0" \
    -device e1000,netdev=net0,bus=pcie.0 -netdev user,id=net0
  3. 安装模块、启动e1000网卡、ping网关 网卡运行
