Faith Ekstrand has provided
an update on the status of the NVK
Vulkan driver for NVIDIA GPUs.

Probably the single most common question I get from folks is, “When
will NVK be in upstream mesa?” The short answer is that it’ll be
upstreamed along with the new kernel API. The new API is going to
be required in order to implement Vulkan correctly in a bunch of
cases. Even though it mostly works on top of upstream nouveau, I
don’t want to be maintaining support for that interface for another
10 years when it only partially works.

We don’t yet have an exact timetable for when the new API will be
ready. I’m currently hoping that we get it all upstream this year
but I can’t say when exactly.
