This page will keep a running list of components used to achieve GPU Virtualization.
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 | 2023.01.06 | CLI, IOCTL, RMAPI, Mediated Core | Allocates GPU resources for use with virtualization. Registers devices and mdev callbacks with the Mediated Core. |
Arc Compute | gvm-mgr | Daemon | docs.linux-gvm.org | 2023.01.06 | IOCTL, RMAPI, vRPC, pRPC, PCI BAR, Mediated Core | Schedules IO to and from the guest GPU driver, handles BAR-quirks (trap and emulate of some or all guest driver IO depending on availability of hardware virtualization assistance). | ||
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. | ||
Intel | i915 SR-IOV | Driver | 5.15 | OSS | Intel's open source GPU driver for GuC-equipped graphics accelerators. | |||
Intel | GuC μOS | Firmware | Blob | IOMMU Interrupts, Power Management Interrupts, GTT | Handles scheduling, and power management. | |||
Intel | HuC | Firmware | Blob | GTT | Handles video encoding/decoding. | |||
Intel | Display Virtualization for Windows OS | Driver | OSS | 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 | 2023.01.31 | Nvidia's open source GPU driver for GSP-equipped graphics accelerators. | ||
Nvidia | GSP RM (uproc) | Firmware | Blob | 2023.01.31 | RPC | Embedded firmware based on LibOS containing the RM Core. | ||
Nvidia | Falcon/NvRISC (uproc) | Firmware | Unknown | Blob | FBIF (Frame Buffer Interface) / GMMU | Embedded firmware which handles many aspects of the device including configuring the GPU's GMMU controller. | ||
Nvidia | nvidia-vgpud | Daemon | v15.1 | Blob | 2023.01.xx | Systemd, Mediated Core | Configures the the nvidia-vgpu-mgr process. | |
Nvidia | nvidia-vgpu-mgr | Daemon | Blob | 2023.01.xx | vmiop, IOCTL, RMAPI, vRPC, pRPC, Mediated Core | Handles IO to and from guest RM, host RM, and hardware. | ||
Nvidia | libnvidiavgpu.so | Library | Blob | 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 | nvidia_vgpu_vfio | Driver | Blob | 2023.01.xx | Type 1 IOMMU, irqfd, ioeventfd, IOCTL, Mediated Core | Handles incremental memory mapping (non-page pinning per the standard vfio-pci driver). |
