Key Takeaway

Intel's upcoming Nova Lake S and P processors will support Single Root I/O Virtualization (SR-IOV) via the Xe kernel graphics driver.

Summary

An Intel engineer has submitted a patch to the Linux kernel mailing list to enable SR-IOV support for Nova Lake S, Nova Lake P, and Intel GPU D Series (Crescent Island) hardware. This change allows integrated graphics to be utilized more effectively in virtualized environments through the Xe driver. The patch adds the relevant PCI IDs to the xe-vfio-pci device table.

Technical details of the SR-IOV patch

Adds Crescent Island (CRI), Nova Lake-S (NVL-S), and Nova Lake-P (NVL-P) PCI IDs to the xe-vfio-pci device table.
Enables userspace to select the variant driver for Virtual Functions (VFs) via generated vfio_pci module aliases.
The patch is currently under review and may target the Linux kernel v7.5 cycle.

Why it matters

This enables better hardware acceleration for virtual machines using Intel's upcoming integrated graphics architectures.
