Intel's open-source Linux engineers have been working a lot recently on the kernel's support for Trust Domain Extensions (TDX). Intel TDX has similarities to AMD's Secure Encrypted Virtualization (SEV) and is ultimately about better protecting virtual machines. The latest patch series published for Linux is the Intel TDX Guest Attestation support for being able to verify a TDX VM's trustworthiness via a third-party server.
Intel's Software Defined Silicon (SDSi) driver is ready to be merged for the Linux 5.18 kernel now that it's been queued into the x86 platform driver's "for-next" branch.
Last month Intel posted a new set of Linux patches for shadow stack support as part of the Control-flow Enforcement Technology (CET) found within their latest processors. Also part of Intel's CET is Indirect Branch Tracking (IBT) while Intel said they were going to first focus on shadow stack (SS) and worry about IBT later. Less than one month later, new Indirect Branch Tracking patches for the Linux kernel have been taking shape.
Intel's forthcoming Arc Graphics "Alchemist" (DG2) graphics cards do support Resizable BAR functionality as covered when they previously published Linux patches for it. They are also now working on a DG2 feature for "small BAR" support.

We still don't know what features Intel is planning to capitalize upon with their Software Defined Silicon "SDSi" functionality in future CPUs, but it turns out the kernel mainlining of the necessary software support is now expanded to land with Linux 5.18. With the SDSi kernel support coming together rather quickly, it's possible we could be seeing Software Defined Silicon rather soon.

Linux 5.16 brought improvements/fixes for Alder Lake S to help the likes of the Core i9 12900K deliver better performance. With the in-development Linux 5.17, the i9-12900K is looking even better. And then on the horizon for Linux 5.18 is the possibility of even better performance thanks to Intel's Hardware Feedback Interface (HFI/EHFI) positioned to land.

To date the Intel Linux graphics driver has supported Intel's DG2 "Alchemist" G10 and G11 sub-platforms/variants as the main designs to this point. However, at the end of last year we began seeing "G12" references surface in their compute stack and now the Intel open-source Linux kernel driver is formally preparing the DG2-G12 variant support.
Way back in August Intel posted a set of Linux kernel patches for supporting "unaccepted memory" by the Linux kernel in preparation for next-generation Xeon processors and speeding up the boot time for guest virtual machines making use of Intel's Trust Domain Extensions (TDX) security feature.
