Unlock vGPU functionality for consumer-grade NVIDIA GPUs.
This tool is to be used with the kernel patches from the main
vgpu_unlock repository!
- This tool requires Rust. You can install it via your package manager or via .
- Rust requires a linker to be installed to be able to create the shared library. Typically, this is installed with the C compiler through your distribution's package manager.
- The dependencies from the main
vgpu_unlockproject excluding Python andfrida.
In the following instructions <path_to_vgpu_unlock_rs> needs to be replaced
with the path to this repository on the target system.
Install the NVIDIA vGPU driver and kernel driver patches as detailed in the
main vgpu_unlock project README. Ignore the steps regarding editing the
systemd service unit files.
Run cargo build --release to compile the shared library.
Create the directories /etc/systemd/system/nvidia-vgpud.service.d and
/etc/systemd/system/nvidia-vgpu-mgr.service.d.
Create the files /etc/systemd/system/nvidia-vgpud.service.d/vgpu_unlock.conf
and /etc/systemd/system/nvidia-vgpu-mgr.service.d/vgpu_unlock.conf
with the following:
[Service]
Environment=LD_PRELOAD=<path_to_vgpu_unlock_rs>/target/release/libvgpu_unlock_rs.so
Create the directory /etc/vgpu_unlock which will house the vGPU profile
override configuration file.
Create the file /etc/vgpu_unlock/profile_override.toml with the profile
fields that are to be overridden. The following is an example for nvidia-55
(GRID P40-2A) that sets the number of heads to 1, sets the framebuffer to be
1920x1080 (1920 * 1080 = 2073600 pixels), enables CUDA, and disables the
frame-rate limiter.
