The open-source project GPU-unlock uses a Linux kernel module to modify hardware registers before driver binding, unlocking the FP/BF16 instruction issue rate on Nvidia RTX 30 series cards. Benchmarks show nearly doubled BF16 performance for GA102-GA106 chips without requiring manual patches after driver updates.
