Intel Panther Lake & Diamond Rapids Model IDs Added For Linux 6.12

Submitted today as the "x86 fixes" for the Linux kernel ahead of the Linux 6.12-rc1 release this evening is adding two new Intel CPU model numbers.

With the Intel Granite Rapids and Sierra/Clearwater Forest enablement cleared along with Intel Lunar Lake and Arrow Lake, the open-source software engineers at the company are beginning to bring-up next-generation Panther Lake cores and Diamond Rapids as the next-gen Xeon P-core processors.

The patch submitted for mainlining today is just adding the new 0xCC model ID for Panther Lake L and then the Family 19 Model 1 identification for Diamond Rapids with its Panther Cove X cores. As I wrote about a few days ago, Diamond Rapids is the generation where Intel Family 6 is ending and being succeeded by Family 19.

Expect more Intel Panther Lake and Diamond Rapids enablement code to be posted soon. On the Panther Lake side there's already been some work like enabling audio support and other bits but the more exciting pieces to come later.

This pull of x86 fixes for Linux 6.12 is what has the model numbers now in place for identification.
