给 Lumia 950 XL 跑 Debian 9 w/ 主线内核

可能是住院期间过于无聊需要找一点事情做（。

其实看上去 MSM8994 的主线情况还是不错的（虽然不像 APQ8016/APQ8096 一样有 SBC，这两款的主线情况是最好的），除了设备树不齐，某些缺的 GCC/RPM 时钟需要补上，还需要一个 qcom,pcie-msm8994 的 PCIe 控制器。补上设备树后很多东西开箱能用。目前跑的是 4.18.6。rootfs 是直接 debootstrap 出来的。

走的 ARM64 UEFI + GRUB 启动，没有用 lk/uboot （都有 UEFI 用了，为什么要用那种玩意？）

Note: 现在这批 "Always Conncted PC" 也就是跑 8998/SDM850 的 Windows PC 虽然没有锁 Secure Boot，但是跑 Linux 有困难，因为它们的固件加载的位置太低了。UEFI 规范建议固件加载得越高越好，虽然这不是强制性要求。跑 Windows 和 XNU （其他系统我没测过）都是没问题的。我自己给 8994 写的 UEFI 实现加载在内存中段，留了足够多的 bottom memory 给 Linux

最后留一个 boot log 开头摘要：

好厉害…… 我在跑 Android 的 835 上尝试改动一点 LinuxLoader (aboot 分区) 都会导致进 9008，即便是解锁了 bootloader 也不行。950XL 可以跑楼主自己修改的 UEFI 实现的话，是绕过了高通的启动验证吗？

@updateing 对，高通的 WP 实现里，Secure Boot 有一个洞，可以在进了 bootmgfw.efi 后选自己的启动程序然后获得整个 EL1 的控制权。aboot 默认是要签名的

@mortal 肠穿孔然后体内攒了 400mL 的积液。头两次去 Urgent Care 他们看不出问题觉得只是胃酸倒流，第三天去拍了片就让我去 Emergency 了，然后拍了个 CT 后被要求住院手术。现在基本恢复了，再晚去几天医院情况就可能控制不住了

不一样, chroot 在一个预定大小的镜像文件中做操作, 很多东西跑服务兼容性不行

完整的 arm linux 系统, 比方说以前在 ac100(一个 android)上跑, 兼容性基本没有问题

@jjx 我朋友的 GSoC 2018 项目就是把 Nexus 6P 上的 Android 关到一个 LXC 里，然后外面跑的是 Gentoo。

https://jsteward.moe/gsoc-2018-final-report.html

当然胶水代码是写了一些的，比如手机开机启动 Gentoo 后启动 LXC 里面的 Android。外面就是个能用的 Gentoo arm64。
