Hi,
This series adds firmware support for Hopper and Blackwell GPUs. By
that I mean: Hopper and Blackwell can now get just as far as Ampere and
Ada do: they can receive a GET_GSP_STATIC_INFO message from the GPU's
GSP firmware, and print the resulting GPU marketing name to dmesg.
Having made that claim, note that I've only actually tested the new
functionality on a single Blackwell GPU, so far: GB202. For Ampere, I've
tested on GA104, and it still works as before.
The doctests are all passing.
This is based on today's drm-rust-next. For reviewer convenience, there
is also a git branch that has this series applied:
https://github.com/johnhubbard/linux/tree/nova-core-blackwell-complete-v0
Note: I've merged in the earlier "[PATCH v2 0/5] gpu: nova-core:
Hopper/Blackwell prerequisites" [1], because it is no longer useful by
itself. That makes for a large series, but now it is entirely
self-contained, so it's easy to apply.
