On Rust in enterprise kernels The players Some context to begin: the nouveau driver handles NVIDIA GPUs. It was, for years, the product of a determined reverse-engineering effort in the absence of any help from NVIDIA; it was first merged into the mainline for the 2.6.33 release in 2009.

NVIDIA clearly thinks, probably with good reason, that this feature will make its GPUs more attractive to cloud providers, which are known to purchase a nontrivial amount of hardware. Backporting worries This new subsystem, as one might expect, is based on VFIO, meaning that the interfaces the kernel already exports for virtualized device control will work with NVIDIA GPUs.
