FreeBSD developers are looking at using the open-source NVIDIA kernel driver being developed by NVIDIA as an open-source Direct Rendering Manager driver that is out-of-tree, but not to be confused with Nouveau.
With that kernel driver they are able to provide this nvidia-drm-kmod driver on their own and within the ports collection for better integration with the kernel and those wanting one less kernel binary blob.
Excellent news for FreeBSD users with NVIDIA cards.
Given the close association that Haiku has to FreeBSD drivers (largely networking though), this could be a genuine boon for Haiku.
Highly unlikely… Haiku has a kinda partial port of Mesa 3d drivers for Radeon but that’s about it for now… it isn’t mainline yet either.
It’s unlikely anyone would try to get the proprietary drivers even working… would be way easier to juts buy compatible hardware.
