    Homebrew low level graphics API for Nintendo Switch (Nvidia Tegra X1)

    Project mention: Nvidia Publishes 73k Lines of 3D Header Files for Fermi Through Ampere GPUs | news.ycombinator.com | 2022-08-09

    That's not exactly correct. This is register maps for the 3d engine (also called class), what you describe would be closer to the shader ISA.

    In driver code you'll see them building command buffers that set registers in those classes to certain values. It could be the RGBA values of the clear color, or a virtual address in the GPU space.

    This documents the names of these registers. This makes reverse engineering somewhat easier as you don't really have to guess anymore. But in most cases it was pretty clear from the start, and for some generations those were already well documented by open source efforts. One of best known gens is probably Maxwell since it was used in the Nintendo Switch, see for instance [1] (or code in yuzu/Ryujinx) which is the equivalent of those headers NV published.

    However this isn't a very big step in documenting their GPUs. The exact functions of those registers aren't explained, but most importantly the shader ISA isn't documented at all, which is essential to build a good open-source driver.

    Source: I have reverse engineered some driver code for Maxwell (and used similar headers to write drivers for nvdec and nvjpg).

  • Scout APM

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
