Is there any spec to support Sdtrig extension?

Since debug triggers defined in the Sdtrig extension can only be accessed by Debug Mode and M-mode, I think an SBI extension is needed to support debug control from S-Mode software.

Yes. The SBI extension is already proposed here and the PoCs are also available
