Singularity 代码阅读笔记[结构: Struct_Microsoft_Singularity_BootInfo]
2024-05-22 22:43:50
在我阅读 Singularity 史前活动的代码时，这个 BootInfo 结构多次出现在代码中，并且来回传递与 C 与 Asm 之间。所以单独提出来方便查阅。

60: };
这两个文件是 Bartok 自动生成的。.h 文件用于 C 语言代码，而 .inc 文件用于汇编语言代码。
Bartok 是一个类似于 JIT 的东东，负责把 IL 代码编译为本机可执行代码。
真正的 BootInfo 在 \base\Kernel\Singularity\BootInfo.cs 文件中定义。
