Mainline Linux supports rk3588 and almost everything works out of box (except power-off). I added some modification to Linux Kernel in this repo. Just run build-kernel.sh (dependens on llvm and clang) and copy extlinux.conf, Image, dtb file and extract modules into /lib/modules.

起因是用gen_compile_commands.py生成的compilation database对于clangd不太友好，便想着用clang构建内核试试，还是遇到了一些问题，也学习到很多东西。

1. scripts/Makefile.extrawarn。clang构建内核需要关掉一些flag，否则会编译失败，这个是最容易修改的。
2. cannot jump from this indirect goto statement to one of its possible targets。在此之前我并不知道gcc还有这样的拓展，这个问题出现在drm相关的代码里面，我用比较丑陋的代码暂时处理了，以后再看看mainline kernel是怎么处理的。
   
3. 数组大小问题。

对我而言这是一次有趣的体验，从lkml的patch里面提取有效信息、看llvm issue、看GCC手册，所以写下来当作消遣。

@Momo-0 I just met this problem, and it was caused by previous job not finishing. https://lkml.org/lkml/2024/1/8/549, I met this problem, and swapped argument, then it compiles
