- [sceAgcDcbPrimeUtcl2](../../../core/libs/prx/libSceAgc/DcbState/src/Display.cpp) (libSceAgc) - assumed to write the packet `sceAgcAcbPrimeUtcl2` writes: PRIME_UTCL2 has the same 5 dwords on the graphics and compute rings. Not confirmed on a title. Both write a NOP of that size, as there is no TLB to prime
- [sceAgcDcbQueueEndOfShaderActionGetSize](../../../core/libs/prx/libSceAgc/DcbState/src/ContextState.cpp) (libSceAgc) - the builder is inline in the SDK and not exported; the size is assumed to be that of the RELEASE_MEM packet `sceAgcCbReleaseMem` writes (32 bytes), the same as `sceAgcAcbQueueEndOfShaderActionGetSize`, as in [OpenAGC](https://github.com/OpenAGC/OpenAGC/blob/main/src/game_compat.c) and [REmu](https://github.com/xnetcat/REmu/blob/main/crates/remu-runtime/src/agc_dcb.rs)
- [sceAgcDcbSetZPassPredicationEnableGetSize, sceAgcDcbSetPredicationDisableGetSize, sceAgcDcbSetBoolPredicationEnableGetSize](../../../core/libs/prx/libSceAgc/DcbState/src/Predication.cpp) (libSceAgc) - the builders are inline in the SDK and not exported; the size is assumed to be that of the SET_PREDICATION packet `sceAgcDcbSetPredication` writes (16 bytes)
- [sceAgcAcbWaitUntilSafeForRendering](../../../core/libs/prx/libSceAgc/Acb/src/Control.cpp) (libSceAgc) - `(buffer, videoOutHandle, displayBufferIndex)`, the declared arguments, which PPSA12544 (01.000.010) passes inside `waitUntilSafeForRendering` and `waitUntilSafeForRendering VR` markers on an asynchronous compute command buffer, ignoring the result. It writes the same rendering-wait packet as `sceAgcDcbWaitUntilSafeForRendering`, which the driver now accepts on compute queues too; the wait blocks only that queue's worker. Whether the console encodes the compute variant differently is not known
- [sceAgcAcbWaitUntilSafeForRendering](../../../core/libs/prx/libSceAgc/Acb/src/Control.cpp) (libSceAgc) - `(buffer, videoOutHandle, displayBufferIndex)`, the declared arguments, which PPSA12544 (01.000.010) passes inside `waitUntilSafeForRendering` and `waitUntilSafeForRendering VR` markers on an asynchronous compute command buffer, ignoring the result. It writes the same rendering-wait packet as `sceAgcDcbWaitUntilSafeForRendering`, which the driver now accepts on compute queues too; the wait blocks only that queue's worker. Whether the console encodes the compute variant differently is not known. In PPSA12544 the Acb function is called from 2 sites (0x11d9538, 0x11d95a4) and the Dcb function from 4 (0x11d76d4, 0x11d7740, 0x16e5eac, 0x16f32a6), each with three arguments and no read of the result; which of the last two arguments is the handle and which the index is not shown.
- [sceAgcGetDefaultCxStateFlat](../../../core/libs/prx/libSceAgc/Misc/src/RegisterDefaults.cpp) (libSceAgc) - copies up to `size` bytes (clamped to 2048 bytes, the 512-dword `AgcContextState`) from the default context state initialized from the version 8 public register default groups (CX, SH, UC), indexed by register offset, following OpenAGC `src/context_state.c`; returns `0x80890001` on null destination; version selection without `sceAgcInit` is unverified
- [sceAgcDcbSetIndexIndirectArgs, sceAgcDcbSetIndexIndirectArgsGetSize](../../../core/libs/prx/libSceAgc/DcbDraw/src/IndexBuffer.cpp) (libSceAgc) - the `(buffer, attributeAddress, attributeIndex)` signature, a 64-bit address and a 32-bit index, is [OpenAGC](https://github.com/OpenAGC/OpenAGC/blob/3c7e8072f0d7684e930454794fd5c02056946d73/src/game_compat.c#L1742-L1757)'s. The console oracle in prosper measured the packet, an INDEX_ATTRIBUTES_INDIRECT (opcode 0x91) holding the low address dword, the high address dword and the index ([measured](https://github.com/mattias800/prosper/blob/3ea5cb9a846b6dcd00f5073360462bbda4f72288/prosper/tests/data/console_oracle/agcbuild.golden.tsv#L172-L174)), and a size of 16 bytes ([measured](https://github.com/mattias800/prosper/blob/3ea5cb9a846b6dcd00f5073360462bbda4f72288/prosper/tests/data/console_oracle/agc.golden.tsv#L67)). The console clears the low four address bits and keeps the low 16 bits of the index; here a nonzero address that is not 16-byte aligned, or an index above 0xffff, throws, as `sceAgcDcbSetIndexBuffer` throws for a misaligned address. A null address is written as 0, as the console writes it. No title is known to call them.
