树莓派官方只维护了基于debian的32位arm版本Raspbian，并没有官方支持的arm64位版本。从树莓派3B开始就已经使用了64位CPU，但是现在已经差不多两年过去了，官方似乎也还并没有要支持64位的意思，这真是一件蛋疼的事情！！！
本身我自己也一直想在pi上面跑64位系统版本，且在树莓派实验室网站也有一篇介绍在pi3B上跑64位系统会比32位系统有近30倍性能提升的文章，这就更加加强了我要跑64位系统的想法。但是找遍网络也没有现成可用的，即使有是其它爱好者自己移植的，例如只有64位内核，rootfs和各种用户态组件都还是使用树莓派官方支持的32位等等......，实际上这样的移植并不是真正的64位系统，只是有一个64位内核，而用户态全都跑在32位模式。唯一一个官方支持pi64位的系统suse linux也只支持3B，并不支持3B+，3B+启动不了suse linux的64位镜像，这种现状不是我想要的，没有办法，只能自己走上折腾之路。
我个人很喜欢debian，且自己在家里和公司里的电脑都是安装debian作为主力系统使用的，所以目光自然就盯上了debian系统。debian没有让我失望，其官方是支持arm64版本的，只是没有官方支持树莓派。既然我们的pi使用的是64柆CPU，是不是也有可能让pi启动debian官方的arm64版本呢？理论上应该是可以的，且我要实现它。所以就定了这个目标，向着目标前进了。
debian的官方arm64版本：debian-9.4.0-arm64-DVD-1.iso
经过多天的研究和探索，终于让debian官方的arm64版本成功在pi上启动(由于debian官方内核不能直接挂载pi上的rootfs，还没来得及研究原因，直接上了自己的内核，所以除内核是自己编译的之外，其它组件都是debian官方的arm64版本，其它一些iso安装文件中没有的软件也都是从debian的国内源通过apt-get安装的)，且网络等重要部件工作正常，可以正常ssh到树莓派，如下是运行展示：
