QEMU模拟运行Zircon(原Magenta)

一 、下载源码:
    $ git clone https://github.com/fuchsia-mirror/zircon.git
or $ git clone https://fuchsia.googlesource.com/zircon

二、安装编译工具链:
    进入源码目录执行(需要科学上网)
    $ cd zircon
    $ ./scripts/download-toolchain

三、编译Zircon:
   $  make -j32 arm64

四、下载QEMU:
    $ cd ..
    $ git clone https://fuchsia.googlesource.com/buildtools
    $ cd buildtools
    $ vim fuchsia.ensure
    $ ./update.sh

    注意:需要下载Google定制的QEMU,亲测QEMU官网或者Ubuntu仓库的QEMU无法正常运行Zircon,会报qemu-system-aarch64: Property '.virtualization' not found错误。

    注意:可以节省下载时间,建议删除fuchsia.ensure中的其他内容,我们只需要下载qemu即可。
fuchsia.ensure最终的内容如下:
# Copyright 2017 The Fuchsia Authors. All rights reserved.

五、使用QEMU模拟运行Zircon:
    $ cd ../zircon
    $ ./scripts/run-zircon-arm64
    运行结果见附录。
    在终端中可以执行cd、ls、ps、top等命令,其他的需要进一步研究。
    
    注意:./scripts/run-zircon-arm64会自动识别到magenta/scripts/../../buildtools/linux-x64/qemu/bin/qemu-system-aarch64
或者可以qemu-system-aarch64所在目录添加到环境变量中。
