Intel Nova Lake-S Gains Xe3P Graphics Support in Linux 7.3

Intel Nova Lake- S desktop processors gain Xe3P graphics support in Linux 7.3, with new PCI IDs added and HuC firmware requirements removed.

is quietly expanding driver support for its upcoming Nova Lake-S desktop processors in the latest kernel updates. This development matters because it signals that the hardware is moving closer to public release, giving enthusiasts and developers early visibility into the architecture. The changes appear in the Linux 7.3 patches, which are expected to merge in the second half of August.

Kernel patches add new graphics identifiers and simplify driver dependencies

The updates focus on the Xe3P graphics architecture integrated into the Nova Lake-S silicon. Intel has added two new PCI device identifiers, 0xD74A and 0xD74B, to the driver code. These entries allow the operating system to recognize specific graphics components within the new desktop chips.

  • Linux Kernel Version: 7.3
  • Graphics Architecture: Xe3P
  • New PCI Device IDs: 0xD74A, 0xD74B
  • Removed PCI Device ID: 0xD744
  • Total Recognized IDs: 7

Alongside the new additions, the driver removed device ID 0xD744 from the Nova Lake-S list. This removal likely indicates that 0xD744 belonged to an earlier engineering sample that is no longer in development. The Xe driver now recognizes a total of seven Nova Lake-S graphics device IDs, suggesting a broader range of potential configurations than previously visible.

A significant technical change involves the Protected Xe Path (PXP) feature for the Media 35 engine. Starting with this engine version, PXP no longer requires HuC firmware from the kernel driver. This simplification removes a dependency on the HEVC/H.265 microcontroller firmware, potentially streamlining the driver stack for developers and users alike.

Intel stated that Nova Lake should appear this year, but the company never clarified if that timeline applies to desktop or mobile variants. The number of recognized PCI IDs does not guarantee a matching number of retail SKUs, as many identifiers change or disappear during development. We touched on Intel Nova Lake CPUs Rumored With in our earlier Intel coverage to track these architectural rumors.

The Linux 7.3 merge window provides a concrete timeline for when these driver changes will reach mainline kernels. This update confirms that Intel is actively refining the software support for Nova Lake-S ahead of any official retail launch. The removal of the HuC firmware requirement marks a specific step toward a cleaner driver experience for Linux users.
