GXEndDisplayList

• Category: Display List
• Matrix Status: Implemented
• Matrix Notes: Verified docs behavior: returns padded 32-byte size with GX_NOP tail, returns 0 on overflow/error path, restores normal submission, and now explicitly flushes on end.
• Matrix Link: Gfx-GX-API-Matrix

Official SDK (Reference)

• Manual root: reference/rvlsdk/man/en_US/gx
• Primary SDK source area: demos/PikminDemo/src/gx (GC-style Dolphin GX source)
• Notes:
  • Confirm official signature/prototype
  • Confirm documented side effects (register/state updates)
  • Confirm special behavior and edge cases from manual

libPorpoise Implementation

• Runtime implementation area: src/gx
• Public API surface: include/dolphin/gx
• Notes:
  • Confirm API signature matches SDK
  • Confirm state writes match SDK semantics
  • Confirm backend behavior in PC renderer path

Validation Checklist

• GX demo coverage checked
• Pikmin usage path checked
• Matrix status updated if needed
• Notes updated with concrete file/function references

Working Notes

• Docs checked against reference/man/gfx/gx/DisplayList/GXEndDisplayList.html and SDK source in reference/gx/GXDisplayList.c.
• Runtime checked in src/gx/pc_gx.c:
  • Calls GXFlush() during end, matching documented behavior.
  • Returns 0 when no display list is active (non-assert PC fail-soft path) or when overflow occurred.
  • On success, returns byte count padded to 32-byte multiple and fills tail with GX_NOP.
  • Clears display-list recording state and resumes normal command submission path.
• Result: function-level parity is correct for end-recording semantics; no runtime code changes needed.
