这几周使用kylin系统里的/proc/config.gz（详见#14楼）编译了诸多内核，官方的从5.4、5.10到6.0、6.6等等，有的是直接编译出错，有的是编译成功，但是启动系统后网络声音全无，不过还是能启动archlinux系统。
我还试了phytium官方gitee上的嵌入式软件 / Phytium-Linux-Kernel（5.10）和飞腾信息技术有限公司 / linux（6.1.y）不管是用自带的config还是我kylin上的config编译出来的核都无法正常启动Archlinux系统，我估计是那些嵌入板用的内核，不适合我这种“pc机”就没有再继续深究下去了。

试了那么多，其中5.10还算成功，网络成功驱动，声音不行。显卡的问题最后再说。
我用的PKGBUILD是照着HougeLangley/phytium-kernel-archlinux 的修改的，这里我学到了很多。
我修改后的PKGBUILD如下：

其中的0001-add-phytium-id-from-acpi-to-stmmac.patch和0002-phytium-ethernet-stmmac.patch来源于铜豌豆 Linux / atzlinux-kernel，这两个patch打上之后可以成功开启网络驱动，这里的其他patch试了一些，有的可能版本问题编译不成功，有的编译成功了没效果，目前和没有找到开启声音的办法。
其中的lc-phytium-config就是kylin系统里的/proc/config.gz。
其中的linux.preset、60-linux.hook、90-linux.hook就是HougeLangley/phytium-kernel-archlinux 里的文件未作修改。顺便说一下直接按照大神的phytium-config我也编译过，网络声音驱动不了，但是能成功启动archlinux.

用makepkg -Ccs编译，成功后在通过pacman -U安装对应的linux-phytium-5.10.153-2-aarch64.pkg.tar.xz包和linux-phytium-headers-5.10.153-2-aarch64.pkg.tar.xz包即可。

最后说一下显卡问题：
我的显卡是:JINGJIA MICRO JM7201 1G（详见#1楼）
通过搜索其核心芯片是mwv206。
景嘉微官方没有提供驱动，在gitee的找到老虎会游泳 / mwv206，应该没有错。
可是archlinux下编译不了，查了下源码，人家支持kylin、vos、deepin、neokylin这几个，典型的专用服务，其他的编不了。于是我切换到kylin下编译，果然没任何问题，然后按照其makeinstall的路径把相关文件复制到archlinux文件目录的对应位置（这是典型的不当操作，大神不要喷我），结果还是不能驱动显卡。
后来查到据说这个显卡有核内驱动和核外驱动，那还得去内核编译着手吗？
但我这个直接从kylinboot目录下拿来5.4.18-85-generic #74-KYLINOS 核显卡驱动的蛮好的呀！我是不是就该老老实实的用这个kylin的5.4.18核算了，唉
革命尚未成功，同志尚需努力！！
