open-gpu-kernel-modules fork adds P2P for RTX 3090/4090/5090 consumer cards
QuixiAI · x · 2026-09-07
QuixiAI (Eric Hartford) released a fork of NVIDIA's open GPU kernel modules (driver 610.57.04) enabling PCIe peer-to-peer (P2P) transfers between GeForce consumer cards — RTX 3090 (GA102), RTX 4090 (AD102), and RTX 5090 (GB202). Inspired by George Hotz/tinygrad's P2P patch (later simplified by aikitoria) and ported to the 610 driver series. It also fixes two issues for unified-memory GPUs like the DGX Spark (GB10), verified on a Spark, including memory drain on last client close. Ships with install and compile scripts.
