Intel Xe Linux Driver Suggests Multiple Crescent Island SKUs
The latest patch for Intel's Xe Linux graphics driver reveals multiple PCI IDs for the upcoming Crescent Island AI accelerator, hinting at an expansion from a single model to multiple SKUs.
Intel Xe Linux Driver Suggests Multiple Crescent Island Models
Intel’s open-source Linux graphics driver developers have made new progress in supporting the upcoming enterprise AI accelerator “Crescent Island.” A recent kernel driver patch indicates the possibility of multiple variations of Crescent Island, which was previously thought to be a single model.
Background: What is Crescent Island?
Crescent Island is an AI inference-focused GPU accelerator announced by Intel last year. Featuring 160GB of vRAM, it is designed for data center AI workloads. While details about the product have been limited so far, the ongoing development of the Linux driver sheds light on its evolution.
New PCI IDs Added to Driver Code
Previously, the Intel Xe kernel driver only included a single PCI device ID, “0x674C,” for Crescent Island. However, in a drm-xe-next pull request submitted last week, four additional device IDs were added: “0x674D,” “0x674E,” “0x674F,” and “0x6750.” All of these have been registered as part of the Crescent Island family.
That said, experts are urging caution. These IDs don’t necessarily represent five distinct product SKUs. Some could be reserved for pre-production variants or future models that are not yet finalized. In driver development, it’s common for more device IDs to be included than there are actual products.
Movement Toward Integration into Linux 7.2 Kernel
The addition of these new PCI IDs is one of the major changes in the drm-xe-next pull request targeting the Linux 7.2 kernel, set to be released next month. This development brings Linux support for Crescent Island closer to reality. Intel engineers are concurrently working on enabling the Xe3P architecture and CRI (Crescent Island), making steady progress on driver preparation.
Industry Impact and Future Outlook
This development suggests that Intel may be expanding its product lineup in the AI accelerator market. The introduction of multiple SKUs could allow Intel to cater to a wider range of customer needs with varying performance and price points. Additionally, early support in the Linux kernel is a critical factor for driving adoption within the open-source ecosystem.
The key question moving forward is which products these device IDs correspond to. Until Intel officially announces product details, changes in the driver code will remain a valuable source of information. The developer community is closely monitoring Intel’s commitment to realizing Crescent Island.
Frequently Asked Questions
