GXSetTevIndRepeat

• Category: Indirect Texturing
• Matrix Status: Implemented
• Matrix Notes: Parity-checked helper that reuses previous-stage indirect texture coordinates via canonical GXSetTevIndirect repeat settings.
• Matrix Link: Gfx-GX-API-Matrix

Official SDK (Reference)

• Manual page: reference/man/gfx/gx/Indirect/GXSetTevIndRepeat.html
• SDK source: reference/gx/GXBump.c (GXSetTevIndRepeat, around lines 589+)
• Verified SDK behavior:
  • Convenience helper that forwards to GXSetTevIndirect with:
    • ind_stage = GX_INDTEXSTAGE0
    • format = GX_ITF_8
    • bias_sel = GX_ITB_NONE
    • matrix_sel = GX_ITM_OFF
    • wrap_s = GX_ITW_0, wrap_t = GX_ITW_0
    • add_prev = TRUE
    • 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: GXSetTevIndRepeat forwards with the same canonical parameter tuple as SDK.
  • Begin-safe behavior is inherited from GXSetTevIndirect.

SDK vs Porpoise Diff

• Signature parity:
  • SDK: void GXSetTevIndRepeat(GXTevStageID tev_stage)
  • Porpoise: same
• Behavioral parity:
  • SDK and Porpoise helper behavior matches.
• Known divergence:
  • None for this helper wrapper.

Validation Checklist

• GX demo coverage checked (repeat helper path)
• 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.
