{{About message}}
This is the index of the Open-IOV wiki. If you are new, read '''[[Project Status]]''' first, then '''[[System Overview]]'''. The wiki is a curated public view of the project's maintained documentation; each page names its canonical document in the [https://git.vgpu.io/open-iov.git/ repository].
== Start here ==
* [[Project Status]] — what works today, what is in progress, what is not started
* [[Install and First Run]] — build, load, and a stock guest driver in about half an hour
* [[System Overview]] — the architecture in one page
* [[FAQ]] — common questions, including "why is nvidia-smi working but CUDA not?"
== Architecture ==
* [[System Overview]] — principle, layer map, data flows
* [[GSP and GSP-RM]] — the firmware interface the project emulates
* [[The Host Module (vgsp.ko)]] — virtual device, emulation core, memory model, forwarding
* [[The Guest Stack and CUDASW]] — what runs unmodified inside the guest
* [[The vGSP Execution Plane (vEP)]] — the execution and completion layer
* [[Introduction to GMMU]] — GPU address translation from first principles
* [[UVM in the Guest]] — unified memory, semaphores, page trees
* [[GMMU Multi-Tenant Protection]] — isolation design for multiple VMs and tenants
* [[Physical GPU Backend and Guest Wiring]] — how guest work reaches real hardware
* [[Guest Driver Lifecycle: A Field Guide]] — boot to CUDA, with real control IDs and log signatures
== CUDA ==
* [[CUDA Userspace Driver]] — the <code>libcuda.so</code> deep dive
* [[The Execution Frontier]] — the GR compute-launch chain and its current wall
== Firmware and reverse engineering ==
* [[GSP 570.144W Firmware Analysis]] — how the 28.5 MB image was decompiled and mapped
* [[Address Reference]] — firmware-side address tables
* [[risc-v-gsp-rm-debugger]] — the firmware runtime workbench (hooks, watchpoints, sessions)
* Historical protocol analyses, kept for the record: [[RPC Message Format]] · [[BAR Emulation Specification]] · [[WPR Management]] · [[Migration Protocol]] · [[GSP RPC Emulation]] · [[Error Codes]] · [[vGPU-IO Integration Guide]]
== Portability and ecosystem ==
* [[Hardware and Software Matrix]] — Reference / Target / Experimental, honestly labelled
* [[HAAEEP and Collaboration]] — the agent-edge use case, collaboration and licensing models
== Reference ==
* [[Glossary]]
* [[FAQ]]
* [[Error Codes]] — historical naming, superseded by the wire status values
== History ==
This wiki previously hosted the OpenMdev / LibVF.IO project documentation (2021–2023). The pages below are archived for reference; they describe earlier projects and architectures, not Open-IOV.
* [[Introduction]] · [[Virtualization Fundamentals]] · [[Virtual I/O Internals]] · [[GPU Driver Internals]] · [[GPU Firmware]] · [[GPU Support]] · [[CPU Support]] · [[Hypervisor Support]] · [[Merged Drivers]] · [[OpenRM]] · [[AMDGPU]] · [[Intel]] · [[Mdev-GPU]] · [[GVM]] · [[Hyperborea]] · [[LIME Is Mediated Emulation]] · [[LibVF.IO Setup Guide]] · [[Looking Glass KVMFR]] · [[VGPU Unlock]] · [[GPU Software Bill Of Materials (SBOM)]]
== Meta ==
* [[Open-IOV:About|About Open-IOV]]
* [[Community]]
* Wiki architecture pages name their canonical source in the repository; when a page and its source disagree, the repository wins.
