loongarch 原生 godot
Qinka
尝试编译 godot 当前的 master分支 ，基本能过，添加一下 loongarch的目标，同时 pcre2 的 jit 根据最新的修改一下，就能编译。
目前遇到的问题
编译好的 editor 不显示界面（点击会有反馈），用的3a6000 的小主机 只有 7a2000 上的 GPU ，估计还是驱动的问题
不支持 vulkan 和 Wayland
执行游戏的时候和打包的时候 遇到了访问空指针的问题
[1] 3203978 IOT instruction (core dumped) ../../godot/bin/godot.linuxbsd.editor.loongarch64 --headless --export-pack[617137.581374] do_page_fault(): sending SIGSEGV to godot.linuxbsd. for invalid read access from 0000000000000000[617137.581382] era = 000055555685d900 in godot.linuxbsd.editor.loongarch64[55555627c000+7648000][617137.581391] ra = 000055555685d900 in godot.linuxbsd.editor.loongarch64[55555627c000+7648000]
此外，测试了一下 godot-rust 写的脚本库能够编译过，就是不知道运行上会有啥问题。
TSiNGKONG
新世界集显，不显示界面，可以试一下：
export LIBGL_ALWAYS_SOFTWARE=true
export GALLIUM_DRIVER=softpipe
./your_prog
这种方式的性能很差，界面比较卡顿。
EMCA
TSiNGKONG softpipe太可怕了
