NVIDIA Fully Adopts Open-Source GPU Kernel Modules in Upcoming R560 Driver Release

NVIDIA has introduced a big shift in its driver technique, transitioning solely to open-source GPU kernel modules with the upcoming R560 driver launch, in line with the NVIDIA Technical Weblog. This transfer builds on the corporate’s preliminary launch of open-source GPU kernel modules with the R515 driver in Could 2022, which was aimed toward datacenter compute GPUs.

Efficiency and New Capabilities

Over the previous two years, NVIDIA has labored diligently to make sure that the open-source GPU kernel modules meet or exceed the efficiency of their proprietary counterparts. The corporate has additionally launched a number of new options, together with:

• Heterogeneous reminiscence administration (HMM) assist
• Confidential computing
• Coherent reminiscence architectures for Grace platforms
• And extra

These developments have led NVIDIA to consider that the time is true for a full transition to open-source GPU kernel modules.

Supported GPUs

Not all GPUs will probably be suitable with the open-source GPU kernel modules. For cutting-edge platforms comparable to NVIDIA Grace Hopper or NVIDIA Blackwell, the open-source modules are obligatory, as proprietary drivers are unsupported. NVIDIA recommends switching to the open-source modules for newer GPUs from the Turing, Ampere, Ada Lovelace, or Hopper architectures.

Nevertheless, older GPUs from the Maxwell, Pascal, or Volta architectures is not going to be suitable with the open-source modules and will proceed utilizing the proprietary driver. For combined deployments with older and newer GPUs, the proprietary driver stays the beneficial possibility.

NVIDIA offers a detection helper script to help customers in figuring out the suitable driver for his or her system.

Installer Adjustments

The default driver put in by all strategies is shifting from the proprietary to the open-source driver. Particular eventualities requiring consideration embody:

• Bundle managers with the CUDA metapackage
• Runfile installations
• Set up helper script
• Bundle supervisor specifics
• Home windows Subsystem for Linux
• CUDA Toolkit

Utilizing Bundle Managers with CUDA Metapackage

When putting in the CUDA Toolkit by way of a bundle supervisor, customers usually set up a top-level cuda bundle, which incorporates each the CUDA Toolkit and the related driver launch. With the upcoming CUDA 12.6 launch, the method will change to favoring the open-source modules by default.

Utilizing the Runfile

For these putting in CUDA or NVIDIA drivers utilizing the .run file, the installer will mechanically choose the best-fit driver for the system. Customers can even manually select between proprietary and open-source drivers by way of UI toggles or command-line overrides.

Utilizing the Set up Helper Script

NVIDIA has created a helper script to information customers in deciding on the suitable driver for his or her GPUs. The script may be run after putting in the nvidia-driver-assistant bundle.

Bundle Supervisor Particulars

NVIDIA recommends utilizing bundle managers to put in CUDA Toolkit and drivers. Particular instructions for various distributions embody:

apt: Ubuntu and Debian-based Distributions

$ sudo apt-get set up nvidia-open

dnf: Purple Hat Enterprise Linux, Fedora, Kylin, Amazon Linux, Rocky Linux

$ sudo dnf module set up nvidia-driver:open-dkms

zypper: SUSE Linux Enterprise Server, OpenSUSE

$ sudo zypper set up nvidia-open

Home windows Subsystem for Linux

WSL makes use of the NVIDIA kernel driver from the host Home windows OS, requiring no particular driver set up inside WSL.

CUDA Toolkit

The set up course of for the CUDA Toolkit stays unchanged. Customers can set up it by way of bundle managers with the next command:

$ sudo apt-get/dnf/zypper set up cuda-toolkit
