Linux 7.3 Adding More Graphics PCI IDs For Intel Nova Lake S

Source Domain: www.phoronix.com

In addition to this week’s drm-intel-next pull request beginning to lay out the Intel kernel graphics driver changes for Linux 7.3, the first drm-xe-next pull request was sent out on Friday. Intel Nova Lake enablement remains the hot area for the Intel GPU driver code.

The Intel Xe driver this week has added more Nova Lake S PCI device IDs for the integrated Xe3P graphics. The 0xD74A and 0xD74B device IDs are added as additional Nova Lake S parts. The 0xD744 device ID though was dropped from the list as no longer an NVL-S device or was just a pre-production / early engineering model.

This now puts it at seven different PCI graphics device IDs for Nova Lake S recognized by the Xe Linux driver. Granted, some may be reserved for pre-production devices, possible but currently unplanned products, etc.

This week’s Intel Xe driver pull for Linux 7.3 also has some additional Nova Lake workarounds, DRM RAS improvements, and various other fixes and clean-ups.

Also beginning with the Media 35 engine with Nova Lake, the Protected Xe Path “PXP” feature no longer requires the HuC firmware. Starting with the next-gen Intel hardware, the HuC firmware is loaded by user-space rather than the kernel and thus no longer a requirement for PXP usage.

The full list of these initial Intel Xe driver patches slated for Linux 7.3 can be found via this pull request. Expect additional Intel Xe driver feature material to land over the next few weeks ahead of the Linux 7.3 merge window in late August.
