libSceHmd2 technical debt
Silent stubs
- libSceHmd2 has no PS VR2 runtime: Initialize returns unsupported-feature, so normal calls never reach initialized device behavior. Reprojection and gaze operations retain their throwing bodies. Four size/alignment queries return measured constants; QueryBufferSizeAlign still throws. Device setup, headset tracking and rendering are not implemented.
Unknown function info
- sceHmd2Open (libSceHmd2) - the handle is the value the console's driver returned to the first open; titles built with an SDK before 7.00 may open for any user, and the firmware's
sceMbusAddHandleByUserIdresult for a user other than the initial one is unknown, so that case throws. 0x8a720006 for a second open is namedAlreadyOpenedfrom its use - sceHmd2SetVibration (libSceHmd2) - the second parameter is checked against 25 only while a headset is connected; its name and unit are unknown. The field of view member names are assumed: of the firmware's default tangents the first is the widest and the last two are equal
- libSceHmd2 legacy exports - SeeThroughDraw, SeeThroughIC, VideoOutEq, WaitShader, SeeThroughCallbackGetPoseDataFunc, ReprojectionClear, ReprojectionSet and RpeorjectionSetParam have no matching symbols or callers in the supplied system modules. Their signatures remain unresolved. ClearUserEventEnd/Start, GazeStart/StopUserCalibration and GazeObjectSelectionTerminate are confirmed to take no arguments; their behavior after initialization remains unimplemented.

Functional

sceHmd2Initialize (libSceHmd2) - the firmware also fails with 0x8a72001f when
sceKernelGetAppInfofails and with 0x8a72000a for some applications, depending on app info fields at 0x2c, 0x4b and 0x4d whose meaning is unknown, and then callssceMbusInit; none of this is modelled -
Reprojection size/alignment queries - all five exports consume no arguments and return two uint64 values in RAX:RDX. Four host queries return values measured without a headset; native display sizes are calculated through the graphics layout service and see-through size follows internal configuration. QueryBufferSizeAlign changes calculation with runtime state; its native pair return type is restored, while its protected body remains unchanged and throws.

FBUEhH9tQ1A (libSceHmd2) - left unimplemented: before initialization it writes the 32-bit value 9 through its second argument and returns 0 when its first argument points at zeroed memory, but returns
0x8a720001without writing when that memory holds 0xAA bytes, and its fourth to sixth arguments answer0x8a720001when null, so the first argument is an in-out structure whose fields are not known -
libSceHmd2 gaze exports - gaze argument registers and input/output directions are recovered. Result queries take a 16-byte size/handle parameter. The 24-byte foveated result contains size, status and a three-float direction; its trailing four bytes are untouched. The 56-byte full result still needs its eye-field semantics. Object selection uses a 120-byte parameter and 56-byte result whose fields remain incomplete. Its initialization and memory-query structures are recovered, including the 32-bit object count and memory size, memory pointer and 64-bit alignment. Calibration data descriptors contain a pointer and signed 32-bit size; calibration status contains two 32-bit selectors and three floats. The underlying calibration blob formats remain incomplete. Raw gaze input is mutable. CalibrationPoint is three floats passed by value in two SIMD registers; SetIpdOffset takes a byte and a float.
-
libSceHmd2 reprojection exports - frame identifiers and predicted display times are 64-bit. Event setters accept a kernel event queue and 32-bit event ID, consumed by sceKernelTriggerUserEvent. Mirroring uses two memory pointers and a separate 32-byte mode/reserved option. Status and current-output queries write 104 and 32 bytes; those field layouts and the reprojection initialization fields remain incomplete. Positional-reprojection mode is a byte with values 0 through 5, not a boolean.
-
Reprojection parameter submission - SetParam and SetParamWithBuffer take a 32-bit buffer-set ID, 64-bit frame ID, parameter pointer and reserved register slot. The parameter contains a layer pointer, signed count and optional 128-byte flags/reserved structure; plain and buffered layer strides are 328 and 472 bytes. Layer union fields remain incomplete. SetRenderConfig consumes three 64-bit slots; only bits 0 and 32 of the first can be nonzero. These exports remain unimplemented.
