I have had a whole slew of code sitting around locally for quite a while now, towards enabling acceleration on these GPUs. Ampere has some significant changes in a few areas. It hadn't been a huge priority to push out due to the lack of available firmware, and I'd taken the opportunity to work it in with numerous other improvements which will benefit earlier chipsets / work towards enabling Vulkan at the same time. However, it turns out Optimus/Prime without copy engine support (engine/ce, which depends on engine/host) is probably not possible. And, likely unusable even if it were. So, I'm working furiously to get those chunks of it ready ASAP to at least enable those use-cases. Hopefully full acceleration will appear not too long afterwards, I'm working with NVIDIA on it.
