[Feature Request] Kernel Config Add Support for Waydroid

[seamt]

[My Device] CM311-1a-YST tvbox, S905L3A soc
[My ROM] Armbian_23.08.0_amlogic_s905l3a_bookworm_6.1.52_server_2023.09.08.img.gz

Waydroid是一个容器软件（基于LXC），用于在Linux系统上运行Android应用，据说自2023年已经可以在官方Armbian运行。
根据网文我整理了内核需要修改的配置项，希望O大能够采纳。@ophub

// for kernel version < 5.17
CONFIG_ASHMEM=y
CONFIG_PSI=y
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_BINDERFS=y
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder,anbox-binder,anbox-hwbinder,anbox-vndbinder"

// for kernel version >= 5.17
CONFIG_MEMFD_CREATE=y
CONFIG_PSI=y
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_BINDERFS=y
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder,anbox-binder,anbox-hwbinder,anbox-vndbinder"

在O大的系统上，我用armbian-kernel命令编译总是失败，提示armbian.tar.xz下载失败，我没有成功编译内核的经验，瞎猜可能原因是我的网络不够稳定。

Problems installing waydroid - missing "binder" kernel module

[ophub]

我在5.15.y/6.1.y/6.6.y的config里添加了对Waydroid的支持，正在在线编译最新版，1小时后你安装测试下。

如果你现在使用的是最新内核版本，可以先更新到旧版内核，再更新到最新版本。

测试后反馈下结果。

[seamt]

谢谢O大，下载测试了你昨天编译的6.1.86和6.6.27内核。二者表现相同，下面就一同讲。

测试环境：
首贴相同的设备。
Waydroid tools，用官网提供的Debian安装方式，最新的稳定版1.42。
Waydroid 初始化用到的LineageOS定制镜像，针对我的硬件设备，只有18版（基于AOSP v11）可以启动Waydroid。system.img有vanila和gapps两种，都可以启动Waydroid，对以上测试内容而言效果相同，gapps版本在vanila基本上增加了google应用。vendor.img有mainline和halium两个版本，只有mainline版本可以启动Waydroid。17和16版的LineageOS只提供了halium版的vendor.img，不能启动Waydroid。18版的system.img搭配17版或16版的vendor.img，同样不能启动Waydroid。

测试结果：
好的方面是，Waydroid桌面顺利启动，少量应用可以正常运行或基本正常运行。
存在问题是，Waydroid桌面启动后桌面壁纸不显示（显示为全黑），多数应用仍不能正常运行。
应用不能正常运行的表现是，打开应用后显示为空白窗体，或打开应用后卡死在欢迎界面。

以Waydroid自带应用为例，
完全正常运行的：计算器，图库，系统设置
卡死在空白窗体的：时钟，日历，音乐，
卡死在欢迎界面的：联系人，文件（Files, com.android.documentsui），Chromium浏览器
（其中“文件”很重要，因为被第三方应用当作路径选择对话窗）

自己安装的应用为例，
完全正常运行的：静读天下，东方财富手机版，Sketchbook
基本正常运行的：Total Commander（自定义文件夹时卡死在文件的欢迎界面），央视频TV版（视频播放中途卡死），Google TTS Engine（打开下载语音库时卡死在空白窗体）
设置界面卡死在空白窗体而无法使用的：讯飞语记（国产TTS应用和TTS引擎），百度输入法
卡死在欢迎界面的：百度地图，Microsoft Edge浏览器，Device Info HW＋
能进入功能界面但是不能工作的：PPSSPP（指定游戏文件夹时卡死在文件的欢迎界面）

以上问题，在网上查不到。我想请你修改内核配置再编译一版。

// for kernel >= 5.17
CONFIG_MEMFD_CREATE=y
CONFIG_PSI=y
CONFIG_ANDROID=y
CONFIG_ANDROID_BINDER_IPC=y
CONFIG_ANDROID_BINDERFS=y
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder"

说明：
CONFIG_ANDROID=y，增加的这一行，有人说有用，有人说没用，我也看不太懂，出处列在下面了。就是想试试看。
CONFIG_ANDROID_BINDER_DEVICES="binder,hwbinder,vndbinder"，这一行删除了"anbox-binder,anbox-hwbinder,anbox-vndbinder"。
我查过Waydroid的最新源码，用不到anbox-xxx设备。anbox-xxx这些设备是为anbox准备的（Waydroid前身）。anbox只支持X11，不支持Wayland，已经于2023年停止开发。Waydroid信赖mesa驱动，mesa的arm gpu驱动对X11的支持尚未完成就已经停止了。综上，在新内核中支持anbox没有意义。

// 完全正常运行的：系统设置 （设备信息页）

// 基本正常运行的：央视频TV版，播放视频几分钟后画面会卡死，可能是硬件资源受限

// 完全正常运行的：计算器（右侧，窗体模式，拖拉边框缩小了窗体，左侧的虚拟终端和Htop为Linux原生应用）

// 完全正常运行的：计算器（全屏模式）

// 自己安装的应用（东方财富），完全正常运行，窗体模式，默认大小

// 自己安装的应用（东方财富），完全正常运行，窗体模式，拖拉边框至满屏

// 自已安装的应用（Device Info HW+），打开后卡死在欢迎界面

// Gnome的应用抽屉（包含下方三行的Android应用）

// Android的应用抽屉

你更新5.15.155试一试，这个系列也启用了支持选项。只有这个系列才有你说的这个选项CONFIG_ANDROID=y

谢谢O大，今天测试了5.15.155，表现和前面新内核6.1.86和6.6.27完全一样。

网上查了查，也没有头绪。建议这组修改配置的内核不要在正式版镜像中发布。
