- [Inactive vertex point size](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) - `PA_CL_VS_OUT_CNTL.USE_VTX_POINT_SIZE` is accepted for lines, triangles and rectangles with `GS_EN` and `HS_EN` clear, when polygon mode is disabled or both faces are filled. Points, patches and absent routing or rasterization registers still throw. Bit 16 selects the misc export's X component as PointSize ([AMD CIK register reference](https://www.amd.com/content/dam/amd/en/documents/radeon-tech-docs/programmer-references/CIK_3D_registers_v2.pdf), PA_CL_VS_OUT_CNTL); ignoring it for non-point rasterization follows [Vulkan PointSize](https://docs.vulkan.org/refpages/latest/refpages/source/PointSize.html). This is inferred, not measured on console hardware. XashPS5 (PPSA19111 v1.3) sets `0x01210000` on a filled triangle draw.

- [sceAgcDriverSetSubmitValidationMode, sceAgcDriverGetSubmitValidationMode, sceAgcDriverSetSubmitValidationConfig, sceAgcDriverGetSubmitValidationConfig, sceAgcDriverSetValidationErrorOutputFrequency, sceAgcDriverGetShaderDebuggingStatus](../../../core/libs/prx/libSceAgcDriver/Unimplemented.cpp) (libSceAgcDriver) - the five validation calls return `0x8A6C1000` without reading their arguments or writing caller memory, and `sceAgcDriverGetShaderDebuggingStatus` returns 1, as [OpenAGC](https://github.com/OpenAGC/OpenAGC/blob/3c7e8072f0d7684e930454794fd5c02056946d73/src/game_compat.c#L250-L291) reads them from Sony's libSceAgcDriver.sprx: each validation export is `mov eax, 0x8a6c1000; ret` in the copy Dragon Quest VII Reimagined bundles (0x7bb0-0x7bf0), and the debugging status is 1 in the firmware 5.50 library (0x6740). The parameters (a 32-bit mode or frequency, a mode output, a configuration pointer) follow OpenAGC and are never read. Whether later retail firmware enables submit validation or shader debugging is unverified; no title in this repository is known to call them

- [Indices far past every vertex fetch](../../../core/libs/prx/libSceAgcDriver/Graphics/src/Draw.cpp) (libSceAgcDriver) - when a draw's highest index is at least 64Ki vertices past the largest per-vertex record count, every index past that count is moved to it in a copy of the indices, so the zero-padded vertex copies are not sized to the original index (PPSA04159 draws a list of `0xffffffff` with primitive restart off, which asked for 160 GiB). Each attribute fetched by vertex index reads zeros there as at the original index (out-of-bounds select 0 or 1); a draw with another out-of-bounds select keeps its indices. The vertex index the shader sees changes for the moved indices, which a shader that reads it directly would notice
|
||||
- [Depth clear draws](../../../core/libs/prx/libSceAgcDriver/Graphics/src/State.cpp) (AGC driver) - a draw with `DB_RENDER_CONTROL.DEPTH_CLEAR_ENABLE` is taken to write `DB_DEPTH_CLEAR` to every pixel it covers whatever the depth test, depth bounds and depth bias say: it is drawn with an always-passing depth write and the viewport depth range pinned to the clear value. The draw is rasterized as submitted, so its coverage is the draw's own. Whether the DB still applies the depth test or HiZ to such a draw is not measured
