Interesting, seems like quite a bit of work is needed to do this in rust, but hopefully that will benefit others who need to do the same. I do wonder if all of the efforts to do it in rust will be worth it though.

Could someone add the definition of "GSP" to HackTerm? What is it?

It's an NVIDIA specific term that is the abbreviation for GPU System Processor. It's a RISC-V core that does all sorts of management tasks on a modern Nvidia card, mostly related to task setup, resource allocation, context switching, adjusting clock speeds, etc.

Thank you for clearing that up 👍

Dunno. All I know is it's tied to supporting reclocking on newer Nvidia GPUs. This is something the Nouveau kernel driver already supports, so I guess this is just rewriting in Rust for the sake of rewriting in Rust.
