GXSetTevIndBumpXYZ

• Category: Indirect Texturing
• Matrix Status: Implemented
• Matrix Notes: Parity-checked single-stage EMBM helper as canonical GXSetTevIndirect wrapper (GX_ITF_8, GX_ITB_STU, wrap off).
• Matrix Link: Gfx-GX-API-Matrix

Official SDK (Reference)

• Manual page: reference/man/gfx/gx/Indirect/GXSetTevIndBumpXYZ.html
• SDK source: reference/gx/GXBump.c (GXSetTevIndBumpXYZ, around lines 559+)
• Verified SDK behavior:
  • Convenience helper that forwards to GXSetTevIndirect with:
    • format = GX_ITF_8
    • bias_sel = GX_ITB_STU
    • matrix_sel = matrix_sel (caller-selected)
    • wrap_s = GX_ITW_OFF, wrap_t = GX_ITW_OFF
    • add_prev = FALSE
    • utc_lod = FALSE
    • alpha_sel = GX_ITBA_OFF
  • Uses CHECK_IN_BGN semantics via wrapper/callee path.

libPorpoise Implementation

• Runtime implementation area: src/gx
• Public API surface: include/dolphin/gx
• Current implementation:
  • src/gx/pc_gx.c: GXSetTevIndBumpXYZ matches the SDK forwarding tuple exactly and routes through GXSetTevIndirect.
  • Begin-safe state mutation is inherited from GXSetTevIndirect.

SDK vs Porpoise Diff

• Signature parity:
  • SDK: void GXSetTevIndBumpXYZ(GXTevStageID tev_stage, GXIndTexStageID ind_stage, GXIndTexMtxID matrix_sel)
  • Porpoise: same
• Behavioral parity:
  • SDK and Porpoise helper behavior matches.
• Known divergence:
  • None for this helper wrapper.

Validation Checklist

• GX demo coverage checked (single-stage EMBM helper setup)
• Pikmin usage path checked (indirect helper forwarding path)
• Matrix status updated if needed
• Notes updated with concrete file/function references

Working Notes

• No runtime patch required for this function; implementation already matched SDK helper behavior.
