The latest Intel Xe kernel graphics driver patches for Linux now indicate multiple PCI IDs for the upcoming [1]Crescent Island "CRI" accelerators rather than just a lone model.

Product details on Intel's Crescent Island inference-optimized GPU with 160GB of vRAM have been light since the original mention of it last year. Intel's open-source Linux graphics driver engineers continue being quite busy though enabling the Xe3P support in Crescent Island and now indications there will be multiple SKUs/versions of this enterprise AI accelerator.

Up to now there was just a single PCI device ID for Crescent Island: 0x674C. But with this past week's drm-xe-next pull request, there are four more device IDs being added to Crescent Island. In addition to 0x674C, there is now 0x674D, 0x674E, 0x674F, and 0x6750 all added as Crescent Island family members.

That's not to say there will necessarily be five different SKUs of Crescent Island as some models may be reserved for pre-production variant(s), reserved for possible but currently unplanned future models, and similar factors that often lead to more device IDs being added than necessarily different products.

In any event now having multiple Crescent Island PCI IDs was one of the exciting bits with [2]this drm-xe-next pull request of new material heading into the Linux 7.2 kernel next month. In addition to those IDs, there is also other ongoing Xe3P / CRI enablement code too.
