Intel Begins Linux Kernel Enablement For Coral Rapids & Razor Lake

Along with Intel posting initial GCC compiler patches for Coral Rapids and Razor Lake processors, the first Linux kernel patch for these future Intel server and desktop/laptop processors have also arrived. Coral Rapids is the successor to next year's Xeon Diamond Rapids server processors. Razor Lake is the successor to the upcoming Nova Lake processors. These Intel CPUs coming out in 2028 should be quite interesting and great seeing the open-source/Linux support now getting underway. On the same day as posting the GCC patches, Tony Luck at Intel posted the first kernel patch for the future hardware. As is customary, the first patch is just laying out the new CPU family/model IDs so follow-on kernel patches making use of those defines can then be posted. Intel Coral Rapids is using the Family 19 Model 8 for identification. For Razor Lake it's Family 18 Model 6, Razor Lake L will be Family 18 Model 7, Razor Lake U will be Family 18 Model 9, and Razor Lake S will be Family 18 Model 10. Now that the first patch is out there establishing those Coral Rapids and Razor Lake definitions, expect the more actual technical enablement patches to begin hitting the Linux Kernel Mailing List in the coming weeks. If all goes well, in the coming months we'll see the Linux kernel support all settled for Coral Rapids and Razor Lake, well ahead of the actual hardware shipping expected in 2028. As always I'm constantly monitoring the kernel mailing list and other sources for being on the lookout for any revealing feature details or other information on these next-gen Intel wares.
