Nova GPU Workshop: vGPU + VFIO: status and 2026 plans
summary
Nova’s Rust-based GPU driver (Nova) already lands two RFCs published and plans a staged vGPU rollout: stage one adds PCI config/SRV cap reads into GSP init and an exported binding for total virtual functions; stage two brings core primitives—memory allocation, BAR mapping, range allocators, interrupts and GSPQ refinements—and firmware upload for VPU blobs; stage three: enable PCI virtual functions (VF) to boot VMs via VFIO patches. Current framebuffer path uses direct mmap for QEMU; DMA-BUF export via EGL is optional depending on use cases.
