Landing this week was this ALSA change for allowing HDMI audio to work for another NVIDIA GPU. The commit by NVIDIA's Aaron Plattner says, "Vendor ID 0x10de0083 is used by a yet-to-be-named GPU chip."
With the "yet-to-be-named" GPU chip is probably referring to Pascal. In the code it's just identified as "GPU 83", per the last two digits of the ID.
NVIDIA's Pascal is due for release this year as the next step past Maxwell. The GeForce 1000 "Pascal" graphics processors are expected to make use of HBM memory, manufactured on a 16nm process, utilize unified memory and NVLink, and have continued power/efficiency improvements while going head-to-head with AMD's upcoming Polaris GPUs.
NVIDIA's Linux team working on Pascal support would hardly be surprising since now for many years they have been providing same-day Linux support via their proprietary graphics driver and with Pascal it's not expected to be any different.
