Describe features you want to add to SPU

I’d like to add custom steps in Cheetah’s preprocessing (setup/offline) phase.
Could you point me to:
The main setup/preprocessing entry function/module (which file)?
I tried tracing the call paths and logic on my side, but I still couldn’t locate the exact entry/call site I’m looking for.

我想在 Cheetah 等协议的预处理（setup/preprocessing）阶段加一些自定义操作。
请问：
预处理相关的入口函数/模块一般在哪个文件里？
我自己也努力跟了一些调用函数和逻辑，但最终还是没找到我想要的入口/调用位置。
