  • 01:2501:25, 23 May 2025 diff hist +780 N NV3 memory mapping Created page with "Understanding the memory mapping of the NV3 is critical for understanding its overall operation. The memory mapping architecture is implemented internally by the NV3 on-die memory controller and exposed to the user via the configuration register interface of the Peripheral Connect Interface (PCI) bus and its siblings and successors, such as AGP (or in later models, PCIe). Two of the maximum six base address registers are exposed via the configuration registers, BAR0 and..."

Most of the pipeline exists, the GPU is detected and drivers initialise on all known supported operating systems, and 2D partially works. However, serious issues understanding the screen to screen blit behaiour are preventing this part from working. Additionally, the DMA engine, required for 3D, is not yet emulated correctly. == NV4 == Very early research and..."

The NV3 version is fairly basic: it stores some manufacture-time configuration info, allows disabling and enabling interrupts, reading and writing interrupt status and enabling and disabling most other subsystems."
