That said, since the open driver only supports Turing and newer GPUs, it's fair to assume that you could mandate SSE 4.2 and AVX1 support on the CPU. While technically possible, it's unlikely that you'll be pairing a recent GPU with a very old CPU. Unfortunately, low-end Celerons and Pentiums don't always have AVX1 support enabled (let alone AVX2).

Hopefully NVIDIA won't regret doing this when that happens...

Well, now you can have stable and open, that's pretty much a first when it comes to GPU drivers.

Well.. it seems that this is a poison pill?
So NVIDIA "released" their kernel driver as open source. By which they mean, they moved most of it to firmware and made the open source driver call into it. There are almost 900 functions implemented in the 34MB firmware, give or take, from what I can see. Broadcom vibes...

Unfortunately I have 10-series cards that now sit in the awkward spot between nouveau and this new driver. For my desktop I guess I can upgrade in a few years time when it becomes a problem. For my laptop though...
