GXGetTexObjAll

• Category: Texture
• Matrix Status: Implemented
• Matrix Notes: Implemented full texture-object aggregate getter (data/size/format/wrap/mipmap).
• Matrix Link: Gfx-GX-API-Matrix

Official SDK (Reference)

• Manual page: reference/man/gfx/gx/Texture/GXGetTexObjAll.html
• SDK source: reference/ACGC-PC-Port/src/static/dolphin/gx/GXTexture.c (GXGetTexObjAll)
• SDK behavior:
  • Returns all core texture-object fields: image pointer, width, height, format, wrap S/T, mipmap flag.
  • No state mutation; pure accessor.
  • SDK debug path asserts non-null texture object pointer, and then writes all output pointers directly.

libPorpoise Implementation

• Public API declaration: include/dolphin/gx/GXGet.h
• Runtime implementation: src/gx/pc_gx_texture.c (GXGetTexObjAll)
• Behavior:
  • Returns the same aggregate fields from PC texture object storage.
  • No side effects.
  • Supports nullable output pointers (fills only pointers that are non-null).

SDK vs Porpoise Diff

• Signature parity:
  • Manual documents GXTexObj*; SDK source uses const GXTexObj*.
  • Porpoise uses GXTexObj*; call-site semantics are equivalent for reads.
• Behavioral parity:
  • SDK: aggregate getter for object fields (data/size/format/wrap/mipmap).
  • Porpoise: same aggregate fields.
• Known divergence:
  • SDK writes all output pointers unconditionally; Porpoise permits null output pointers and skips those writes.

Validation Checklist

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

Working Notes

• No runtime code change required in this pass.
