缘起

随着aarch64在手机和服务器上面的普及，我们越来越有必要学习一下aarch64的知识，但是目前市面上面还没有做的很好的aarch64的开发板，之前我买了一块NanoPC-T3，用的SoC是Samsung的6818，是cortex-a53 八核架构，但是商家给的资料全都是32位的（armv8兼容aarch32和aarch64），他们说Samsung没有给64位的BSP资料，所以只能等待Samsung来解决，这样的结果令我很失望，偶然看到网上有人用Qemu模拟器来搭建aarch64的运行环境，让我看到了曙光，所以从网上搜刮了一下资料，为后人铺路。

下面涉及到的软件包可以到这里下载。

具备的功能

模拟一个cortex-a53 双核或者单核的环境，同时可以跟Host通信，以便于共享一些文件，为了简单起见，根文件系统使用的是ramdisk格式。

正文

1、编译Qemu模拟器

首先到Qemu官网下载最新的模拟器，我下到的是Qemu-2.8.0，也可以下载其他版本

1 tar -xf qemu-2.8.0.tar.xz
2 cd qemu-2.8.0/
3 mkdir build
4 cd build/
5 # 需要安装这个软件包，因为我们使能了--enable-virtfs， 否则configure的时候会失败
6 sudo apt-get install libcap-dev  
7 ../configure --target-list=arm-softmmu,i386-softmmu,x86_64-softmmu,aarch64-linux-user,arm-linux-user,i386-linux-user,x86_64-linux-user,aarch64-softmmu --audio-drv-list=alsa --enable-virtfs
8 make -j8
9 sudo make install

然后就可以使用我们下面会用到的qemu-system-aarch64工具了。

2、下载工具链

登录这个网址：http://www.veryarm.com/aarch64-linux-gnu-gcc

其中有一些注意事项：

aarch64-linux-gnu-gcc是由 Linaro 公司基于GCC推出的的ARM交叉编译工具。可用于交叉编译ARMv8 64位目标中的裸机程序、u-boot、Linux kernel、filesystem和App应用程序。aarch64-linux-gnu-gcc交叉编译器必须安装在64为主机上，才能编译目标代码。

我们这里使用的是最新的Linux解压版：

3、下载编译最新的Linux内核

登录https://www.kernel.org/，   下载最新的Linux版本，目前最新的是Linux-4.10。 

下面是编译下面要用的kernel的命令：

1 #!/bin/bash
2 cross_compile=/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin/aarch64-linux-gnu-
3 make CROSS_COMPILE=$cross_compile ARCH=arm64 O=./out_aarch64 defconfig
4 make CROSS_COMPILE=$cross_compile ARCH=arm64 O=./out_aarch64 menuconfig
5 make CROSS_COMPILE=$cross_compile ARCH=arm64 O=./out_aarch64 Image -j4

由于下面要用到ramdisk的启动方式，需要在kernel配置中支持：

1 General setup  --->
2     ----> [*] Initial RAM filesystem and RAM disk (initramfs/initrd) support
3 
4 Device Drivers  --->
5     [*] Block devices  --->
6             <*>   RAM block device support
7             (65536) Default RAM disk size (kbytes)

这里我们给ramdisk设置的默认大小是64MB，不能比后面我们实际生成的ramdisk.img的size小。

此外，由于我们还需要支持NFS挂在以及通过9p的方式跟Host共享文件，这些也需要在kernel中进行相应的配置。（默认配置已经支持了）

关于Qemu的9p方式实现跟Host的目录共享可以参考 ： qemu中使用9p，支持host和guest中共享目录    

这样就有了我们下面要用到的内核镜像Image。

4、制作根文件系统

登录https://busybox.net/downloads/下载要用的busybox版本，这里我下的是busybox-1.24.2

要设置的不多：

执行make menuconfig，配置下面几项：

1 Build Options  --->
2 
3     [*] Build BusyBox as a static binary (no shared libs)
4 
5     (/home/pengdonglin/src/qemu/aarch64/gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin/aarch64-linux-gnu-) Cross Compiler prefix

然后执行make && make install命令

下面制作启动用的ramdisk，我把这个过程写成了脚本，如下：

 1 #!/bin/bash
 2 sudo rm -rf rootfs
 3 sudo rm -rf tmpfs
 4 sudo rm -rf ramdisk*
 5 sudo mkdir rootfs
 6 sudo cp ../busybox-1.24.2/_install/*  rootfs/ -raf
 7 sudo mkdir -p rootfs/proc/
 8 sudo mkdir -p rootfs/sys/
 9 sudo mkdir -p rootfs/tmp/
10 sudo mkdir -p rootfs/root/
11 sudo mkdir -p rootfs/var/
12 sudo mkdir -p rootfs/mnt/
13 sudo cp etc rootfs/ -arf
14 sudo mkdir -p rootfs/lib
15 sudo cp -arf ../gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/aarch64-linux-gnu/libc/lib/aarch64-linux-gnu/* rootfs/lib/
16 sudo rm rootfs/lib/*.a
17 sudo ../gcc-linaro-aarch64-linux-gnu-4.9-2014.07_linux/bin/aarch64-linux-gnu-strip rootfs/lib/*
18 sudo mkdir -p rootfs/dev/
19 sudo mknod rootfs/dev/tty1 c 4 1
20 sudo mknod rootfs/dev/tty2 c 4 2
21 sudo mknod rootfs/dev/tty3 c 4 3
22 sudo mknod rootfs/dev/tty4 c 4 4
23 sudo mknod rootfs/dev/console c 5 1
24 sudo mknod rootfs/dev/null c 1 3
25 sudo dd if=/dev/zero of=ramdisk bs=1M count=16
26 sudo mkfs.ext4 -F ramdisk
27 sudo mkdir -p tmpfs
28 sudo mount -t ext4 ramdisk ./tmpfs/  -o loop
29 sudo cp -raf rootfs/*  tmpfs/
30 sudo umount tmpfs
31 sudo gzip --best -c ramdisk > ramdisk.gz
32 sudo mkimage -n "ramdisk" -A arm -O linux -T ramdisk -C gzip -d ramdisk.gz ramdisk.img

制作ramdisk用到的文件到这里下载。

5、Qemu支持网络

请参考博客：

用Qemu模拟vexpress-a9 --- 配置 qemu 的网络功能

用Qemu模拟vexpress-a9 （三）--- 实现用u-boot引导Linux内核

6、测试

共享目录的方法：

 1 sudo qemu-system-aarch64 \
 2     -M  virt \
 3     -cpu cortex-a53 \
 4     -smp 2 \
 5     -m 4096M \
 6     -kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \
 7     -nographic \
 8     -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \
 9     -initrd ./rootfs/ramdisk.img \
10     -fsdev local,security_model=passthrough,id=fsdev0,path=/nfsroot \
11     -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare

 支持网络的启动：

 1 sudo qemu-system-aarch64 \
 2     -M  virt \
 3     -cpu cortex-a53 \
 4     -smp 2 \
 5     -m 4096M \
 6     -kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \
 7     -nographic \
 8     -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \
 9     -initrd ./rootfs/ramdisk.img \
10     -net nic,vlan=0 -net tap,vlan=0,ifname=tap0

当然，也可以将上面的两种方是合在一起：

 1 sudo qemu-system-aarch64 \
 2     -M  virt \
 3     -cpu cortex-a53 \
 4     -smp 2 \
 5     -m 4096M \
 6     -kernel ./linux-4.10/out_aarch64/arch/arm64/boot/Image \
 7     -nographic \
 8     -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc ignore_loglevel" \
 9     -initrd ./rootfs/ramdisk.img \
10     -net nic,vlan=0 -net tap,vlan=0,ifname=tap0 \
11     -fsdev local,security_model=passthrough,id=fsdev0,path=/nfsroot \
12     -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare

我们需要在Host上面先指定一个共享目录， 比如就用/nfsroot，如果用nfs挂载的话还需要在/etc/export中进行相应的配置。

nfs挂载：

mount -t nfs -o nolock 172.16.14.203:/nfsroot /mnt

9p挂载：

mount -t 9p -o trans=virtio,version=9p2000.L hostshare /mnt2

在/etc/fstab中可以写成如下方式：

hostshare  /mnt   9p   trans=virtio,version=9p2000.L   0   2

这样就实现了跟Host的文件共享， 推荐用9p的方式，这个更稳定一些。

下面是启动信息：

  1 $./run_all.sh 
  2 sudo tunctl -u root -t tap0
  3 TUNSETIFF: Device or resource busy
  4 sudo ifconfig tap0 0.0.0.0 promisc up
  5 sudo brctl addif br0 tap0
  6 brctl show
  7 bridge name    bridge id        STP enabled    interfaces
  8 br0        8000.2a30f59a82a1    no        eth0
  9                             tap0
 10 docker0        8000.02429cade970    no
