Ilya Chugin (x512) and Gerasim Troeglazov (3deyes) recently showcased their latest advancements in porting Nvidia graphic drivers for the OS Haiku. This port is being developed based on open modules for the Linux kernel, which were released by NVIDIA and are utilized in their proprietary drivers, both in kernel space and user space. This development includes the Vulkan driver NVK from Mesa.
An interesting aspect of this approach is that it eliminates the need to port the Nouveau driver from the Linux kernel, along with its dependencies on Libdrm and specific subsystems unique to the Linux kernel. The progress of the port has reached a stage where games like S.T.A.L.K.E.R. Clear Sky, doom 3, Minecraft 1.20.4, and Assaultcube can be run with hardware acceleration.
