Revision as of 19:35, 7 March 2023
This page will keep a running list of components used to achieve GPU Virtualization.
An absence of critical technical documentation has historically slowed growth and adoption of developer ecosystems for GPU virtualization.
This CC-BY-4.0 licensed content can either be used with attribution, or used as inspiration for new documentation, created by GPU vendors for public commercial distribution as developer documentation.
Where possible, this documentation will clearly label dates and versions of observed-but-not-guaranteed behaviour vs. vendor-documented stable interfaces/behaviour with guarantees of forward or backward compatibility.
| Vendor | Component | Description | Version | OSS or Blob | Vendor Docs | Release Date | Interfaces / APIs | Notes |
|---|---|---|---|---|---|---|---|---|
| Arc Compute | gvm-cli | Daemon | 1.0 | OSS | docs.linux-gvm.org/gvm-user | 2023.01.06 | CLI, IOCTL, RMAPI, Mediated Core | Allocates GPU resources for use with virtualization. Registers devices and mdev callbacks with the Mediated Core. |
| gvm-guest | Daemon | 0.1.0 | OSS | docs.linux-gvm.org/gvm-guest | 2023.02.08 | Virtio-Serial, CLI | Handles IO to and from guests and the host using Virtio-Serial to handle multiple different guest modules. | |
| Microsoft | Indirect Display Driver (IDD) | Driver | OSS | Indirect Display Driver Overview | UMDF, KMDF | The Indirect Display Driver (IDD) enables GPUs to render graphics at arbitrary resolutions without a physical display connected on Windows OS systems. | ||
| RedHat | vfio_pci | Driver | 6.2-rc1 | OSS | RedHat, kernel.org | 2022.12.15 | irqfd, ioeventfd, IOCTL | Reference VFIO Stub driver used for discrete assignment of IO, and assignment of some SR-IOV-backed vGPU devices into virtual machines. This driver is commonly replaced with a vendor built VFIO interface with differing memory management and/or page pinning mechanisms which are specific to the vGPU software internals. |
| Intel | i915 SR-IOV | Driver | 5.15 | OSS | Intel's open source GPU driver for GuC-equipped graphics accelerators. | |||
| GuC μOS | Firmware | Blob | IOMMU Interrupts, Power Management Interrupts, GTT | Handles scheduling, and power management. | ||||
| HuC | Firmware | GTT | Handles video encoding/decoding. | |||||
| Display Virtualization for Windows OS | Driver | 791 | OSS | github.com/intel/Display-Virtualization-for-Windows-OS/blob/main/Readme.txt | udmabuf, UMDF, KMDF | Intel's 'Display Virtualization for Windows OS' provides a virtual pixel surface used for hardware graphics rendering using Microsoft's open source 'Indirect Display Driver (IDD)'. Display virtualization for Windows OS makes use of display memory sharing primitives provided in-driver by the i915 host. | ||
| Nvidia | OpenRM | Driver | 525.85.12 | OSS | github.com/NVIDIA/open-gpu-kernel-modules/blob/main/README.md | 2023.01.31 | Nvidia's open source GPU driver for GSP-equipped graphics accelerators. | |
| GSP RM (uproc) | Firmware | Blob | 2023.01.31 | RPC | Embedded firmware based on LibOS containing the RM Core. | |||
| Falcon/NvRISC (uproc) | Firmware | FBIF (Frame Buffer Interface) / GMMU | Embedded firmware which handles many aspects of the device including configuring the GPU's GMMU controller. | |||||
| nvidia-vgpud | Daemon | v15.1 | Blob | docs.nvidia.com/grid | 2023.01.xx | Systemd, Mediated Core | Configures the the nvidia-vgpu-mgr process. | |
| nvidia-vgpu-mgr | Daemon | 2023.01.xx | vmiop, IOCTL, RMAPI, vRPC, pRPC, Mediated Core | Handles IO to and from guest RM, host RM, and hardware. | ||||
| libnvidiavgpu.so | Library | 2023.01.xx | vmiop, RMAPI, Mediated Core | Handles IO to and from guest RM, host RM, and hardware. Contains circular dependancies with nvidia-vgpu-mgr. | ||||
| nvidia_vgpu_vfio | Driver | 2023.01.xx | Type 1 IOMMU, irqfd, ioeventfd, IOCTL, Mediated Core | Handles incremental memory mapping (non-page pinning per the standard vfio-pci driver). |
