# libSceComposite technical debt

### Silent stubs

- [sceCompositorCreateIndirectRenderTarget, sceCompositorDeleteIndirectRenderTarget, sceCompositorSetIndirectCanvasCommand, sceCompositorSetIndirectCompositionCommand and sceCompositorSetIndirectRenderTargetConfigCommand](../../../core/libs/prx/libSceComposite/Export.cpp) return error codes or success without managing compositor canvas or indirect render target state.

### Unknown function info

- [sceCompositorGetNullCanvasHandle, sceCompositorSetMainPortPixelFormat, sceCompositorGetVirtualCanvasHandle, sceCompositorSetCanvasIdToCanvasHandle, sceCompositorSetMetaIdToCanvasHandle, sceCompositorSetMainPort and sceCompositorSetVirtualCanvasRenderTargetCommand](../../../core/libs/prx/libSceComposite/Export.cpp) - signatures and behavior remain unknown. The parameterless `int` declarations only resolve imports, make no ABI claim and every call throws through `NotImplemented_nid_no_patch`. Names and NIDs are recorded in the [13.60 export inventory](https://github.com/xdCloudy/PS5-13.60-Function-Stub-Library/blob/bfec40deb4c47a17d7603ee2bc79aa6862c0c56b/data/firmware-13.60/libscecomposite-23841193cf.jsonl); not measured on a console.
- [sceCompositorIsVirtualCanvasHandle](../../../core/libs/prx/libSceComposite/Export.cpp) - what a virtual canvas handle is and which calls make one are unknown. It follows firmware 13.42's libSceComposite.sprx (the copy in libSceCompositeExt.sprx has the same code), read from its disassembly and run natively on x86-64 (not a console): it takes a 32-bit handle and returns true exactly when bits 8 to 15 are all set, without reading any library state

- [sceCompositorMemoryPoolCommit, sceCompositorGetSecondaryMemorySize, sceCompositorGetMemoryPoolAddress, sceCompositorGetSecondaryMemoryAddress, sceCompositorSecondaryMemoryCreate, sceCompositorGetMemoryPoolSize, sceCompositorPermanentMemoryCreate and sceCompositorMemoryPoolCreate](../../../core/libs/prx/libSceComposite/Export.cpp) - signatures and behavior remain unknown. The parameterless `int` declarations only resolve imports, make no ABI claim and every call throws through `NotImplemented_nid_no_patch`. Names and NIDs are recorded in the [13.60 export inventory](https://github.com/xdCloudy/PS5-13.60-Function-Stub-Library/blob/bfec40deb4c47a17d7603ee2bc79aa6862c0c56b/data/firmware-13.60/libscecomposite-23841193cf.jsonl); not measured on a console.

- [sceCompositorGetTFRing, sceCompositorStopSeeThroughBuffer, sceCompositorSetNativeVrVideoOutMode, sceCompositorWaitEndOfRenderingIfGpuWorking, sceCompositorSetFlipCommand3, sceCompositorSetTFRing and sceCompositorStartSeeThroughBuffer](../../../core/libs/prx/libSceComposite/Export.cpp) - signatures and behavior remain unknown. The parameterless `int` declarations only resolve imports, make no ABI claim and every call throws through `NotImplemented_nid_no_patch`. Names and NIDs are recorded in the [13.60 export inventory](https://github.com/xdCloudy/PS5-13.60-Function-Stub-Library/blob/bfec40deb4c47a17d7603ee2bc79aa6862c0c56b/data/firmware-13.60/libscecomposite-23841193cf.jsonl); not measured on a console.

- [sceCompositorAllocateIndex, sceCompositorCheckCrash, sceCompositorCommandGpuPerfBegin, sceCompositorCommandGpuPerfEnd, sceCompositorFlush, sceCompositorFlushWithRepeat, sceCompositorGetAnotherProcessSystemAddress, sceCompositorGetAnotherProcessSystemSize, sceCompositorGetAnotherProcessVideoAddress, sceCompositorGetAnotherProcessVideoSize, sceCompositorGetCanvasHandle, sceCompositorGetClientList, sceCompositorGetDmemOffset, sceCompositorGetDummyAddress, sceCompositorGetDummySize, sceCompositorGetRemainedCommandNum, sceCompositorGetRenderTargetResolution, sceCompositorGetSystemAddress, sceCompositorGetSystemSize, sceCompositorGetVideoAddress, sceCompositorGetVideoSize, sceCompositorHandleProcessEvents, sceCompositorInit, sceCompositorInitWithProcessOrder, sceCompositorInsertThreadTraceMarker, sceCompositorIsDebugCaptureEnabled, sceCompositorIsReady4K, sceCompositorLockCommandBuffer, sceCompositorMakeCanvasHandle, sceCompositorMapAnotherProcess, sceCompositorMemoryPoolDecommit, sceCompositorPrivacyMaskPushArea, sceCompositorQuit, sceCompositorReleaseCommandBuffer, sceCompositorReleaseIndex, sceCompositorReleaseLocalStall, sceCompositorReserveCommandBuffer, sceCompositorResetZoomCommand, sceCompositorSetAgcCompositeCanvasCommand, sceCompositorSetAgcContextCommand, sceCompositorSetCompositeCanvasCommandInC, sceCompositorSetCursorImageAddress, sceCompositorSetDebugPositionCommand, sceCompositorSetEndOfFrameCommand, sceCompositorSetEventCommand, sceCompositorSetFilterType, sceCompositorSetFlipCommand2, sceCompositorSetGameSufaceControlCommand, sceCompositorSetGnmContextCommand, sceCompositorSetInvisibleCanvasCommand, sceCompositorSetKeepDisplayBufferCommand, sceCompositorSetLocalStallCommand, sceCompositorSetMemoryCommand, sceCompositorSetPatchCommand, sceCompositorSetPostEventCommand, sceCompositorSetRepeatCommand, sceCompositorSetResolutionCommand, sceCompositorSetScalingLayoutInfo, sceCompositorSetSeparateContextCommand, sceCompositorSetSystemConfigWithMask, sceCompositorSetVideoOutMode, sceCompositorSetVirtualCanvasAgcContextCommand, sceCompositorSetVirtualCanvasCommandFooter, sceCompositorSetVirtualCanvasPatchCommand, sceCompositorSetVrMode, sceCompositorSetZoomCommand, sceCompositorSystemConfig, sceCompositorWaitEndOfRendering, sceCompositorWaitEvent, sceCompositorWaitPostEvent, sceCompsoitorGetGpuClock, sceCompsoitorGetProcessRenderingTime and sceCompsoitorGetRenderingTime](../../../core/libs/prx/libSceComposite/Export.cpp) (libSceComposite) - names and NIDs are present in the [PS5 3.20 export inventory](https://github.com/DNNDHH/PS5-3.20_Libs/blob/b2a77c09cd71c01f34c790cfbe98c751a13262ad/libSceComposite.c), but no credible prototypes were found. The declarations have no parameters solely to resolve known imports; this is not an ABI claim and callers must not call them until signatures are verified

### Additional callable exports

- [Additional callable exports](../../../core/libs/prx/libSceComposite/Export.cpp) - 29 entries present in both version-labelled images are import-resolution declarations only. None is listed in the pinned public 3.20 catalogue for this library. Neither label independently authenticates retail firmware provenance. Parameter lists, return types and behavior are unverified; parameterless `int` declarations are placeholders, not verified ABI contracts. Every entry throws through `NotImplemented_nid_no_patch`. Unidentified names use literal NID aliases. No runtime functionality is implemented. Data exports require separate layout and ownership analysis. Identified candidate names match their NIDs in the [public symbol database](https://github.com/zecoxao/sce_symbols/blob/2883963a0a514ba6e77407a08ef4730a65e88254/aerolib.csv) or [supplemental catalog](https://github.com/claimore22/ps5rs/blob/2304be5131221bae0dac24b9767cabffda33f747/data/nids.csv).
