Score: 8.5/10 (Innovation: 9, Technical: 10, Documentation: 8, Utility: 7)

nv-uefi-unlocker is a Rust-based UEFI DXE pre-driver tool that performs a full firmware transaction to unlock NVIDIA GPU performance (e.g., FP32 GEMM +67-75% on RTX 20/30/40 series) before Windows loads. It chains SEC2 scrubbing, signed GSP-RM boot, a V67 four-write payload, readback verification, and FLR, then hands control back to the Windows Boot Manager. The project is remarkable for its deep reverse-engineering of proprietary NVIDIA firmware internals and its reproducible asset pipeline from pinned public inputs.

Target audience: hardware enthusiasts, GPU reverse engineers, systems programmers, overclockers, AI/ML practitioners seeking extra compute
