libSceVrTracker technical debt

Unknown function info

• VrTracker parameters: argument slots are recovered. CPU processing and GPU waiting consume 32-byte records, result queries consume 56-byte records, and time queries write 64 bits. Initialization accepts 128-byte and 144-byte versions; the 144-byte layout includes three address/size/alignment records, but configuration selector semantics and the older field layout remain unresolved. GPU submission accepts 552-byte and 648-byte versions; submission and result records still require field recovery; result storage has 1520-byte and 3640-byte variants. Result-query records have a signed handle, 64-bit time, 32-bit selectors and an extended-result flag; selector meanings and the four-byte value copied unchanged to result offset 448 remain unresolved. CPU mode/argument semantics are unresolved. Protected bodies remain unchanged.
• sceVrTrackerCpuPopMarker, sceVrTrackerCpuPushMarker, sceVrTrackerGetLiveCaptureId, sceVrTrackerResetAll, sceVrTrackerSaveInternalBuffers and sceVrTrackerSetDeviceRejection (libSceVrTracker) - the list is the intersection of the export table of the console's libSceVrTracker (function symbols only), pinned aerolib names and functions not yet defined anywhere in the repo. Inventory; aerolib. No credible prototypes were found; these no-parameter declarations only resolve imports, make no ABI claim and must not be called until signatures are verified.
• sceVrTrackerSetExtendedMode, sceVrTrackerSetLEDBrightness, sceVrTrackerSetRestingMode, sceVrTrackerStartLiveCapture and sceVrTrackerStopLiveCapture (libSceVrTracker) - the list is the intersection of the export table of the console's libSceVrTracker (function symbols only), pinned aerolib names and functions not yet defined anywhere in the repo. Inventory; aerolib. No credible prototypes were found; these no-parameter declarations only resolve imports, make no ABI claim and must not be called until signatures are verified.
• sceVrTrackerGetPlayAreaWarningInfo and sceVrTrackerNotifyEndOfCpuProcess (libSceVrTracker) - the list is the intersection of the export table of the console's libSceVrTracker (function symbols only), pinned aerolib names and functions not yet defined anywhere in the repo. Inventory; aerolib. Parameter shapes follow the pinned shadPS4 declarations, not measured on a PS5.
• sceVrTrackerResetOrientationRelative and sceVrTrackerUpdateMotionSensorData (libSceVrTracker) - the list is the intersection of the export table of the console's libSceVrTracker (function symbols only), pinned aerolib names and functions not yet defined anywhere in the repo. Inventory; aerolib. Parameter shapes follow the pinned shadPS4 declarations, not measured on a PS5.

Functional

• tracker lifecycle and devices (libSceVrTracker) - sceVrTrackerQueryMemory, sceVrTrackerInit, sceVrTrackerTerm, the three sceVrTrackerRegisterDevice* calls, sceVrTrackerUnregisterDevice, sceVrTrackerRecalibrate, sceVrTrackerSetDurationUntilStatusNotTracking and sceVrTrackerGpuWaitAndCpuProcess follow shadPS4, a PS4 implementation: its struct layouts, memory sizes, argument checks, one handle per device type and DEVICE_NOT_REGISTERED for an HMD recalibration. Only the 128-byte init parameter is read; the 144-byte one throws. Unlike shadPS4, the init memory ranges are not looked up, a null init parameter and negative device types are refused. Terminating keeps the registered handles, as there. With no camera there is no GPU submission, so the GPU wait returns NOT_EXECUTE_GPU_SUBMIT. Not measured on a PS5
