Intel Posts Latest 113 Patches For Linux KVM TDX Support
29 May 08:38 AM EDT - Intel - Kernel-based Virtual Machine - Add A Comment

One of the new features of Intel Xeon Scalable 4th Gen "Sapphire Rapids" server processors is support for Trust Domain Extensions (TDX) but for this generation is only being activated for CPUs going to select cloud providers. Intel TDX allows better isolating virtual machines from the VMM/hypervisor and other non-TD software on the platform. This limited roll-out of Intel TDX has worked out okay with the Linux support for this security feature still being in flux. Sent out today was the 14th spin of the 113 patches needed for getting KVM TDX support wired up within the Linux kernel.

Linux Lands Fix For Potentially Bogus Number Of Intel Hybrid CPU HT Siblings
Linux Lands Fix For Potentially Bogus Number Of Intel Hybrid CPU HT Siblings
28 May 08:11 AM EDT - Intel - Fixed For Linux 6.4-rc4 - 2 Comments

A few days ago I wrote about a Linux kernel patch being prepared for fixing Intel hybrid CPU SMP/HT topology reporting due to the way the Linux kernel was currently counting the number of Hyper Threading siblings for each core. Fortunately, that fix which is apparently becomes more pressing for upcoming Meteor Lake processors, has now been picked up in time for today's Linux 6.4-rc4 release and is set for back-porting to stable kernel series.

Linux Preps Hybrid SMP Fix To Avoid Upcoming Laptops Appearing As 11 Socket Monsters
26 May 08:17 AM EDT - Linux Kernel - Hybrid SMP Topology Fix - 8 Comments

A fix is on its way to the mainline Linux 6.4 kernel and also marked for back-porting to existing stable kernel series to fix x86 topology reporting for Intel Hybrid systems. The topology bug within the kernel becomes more pronounced for Meteor Lake laptops where currently internal Intel test laptops can report the systems having 11 CPU sockets rather than the proper number of cores all contained within one CPU socket.

Big Throughput Boost & Lower Latency With New Patch For Linux Checksum Function
26 May 06:21 AM EDT - Linux Kernel - csum_partial - 12 Comments

Queued up ahead of the Linux 6.5 cycle kicking off in about one month is a new Linux x86 optimization patch for further tuning csum_partial, the function used within the kernel for calculating 32-bit checksums on blocks of data. Much lower latency and higher throughput can be observed with the newly-optimized csum_partial on the latest Intel/AMD processors.

Intel Engineers Revise Key Locker Implementation For Linux
25 May 08:03 AM EDT - Intel - Intel Key Locker v7 - 4 Comments

Going back to 2020 has been work by Intel's open-source engineers on implementing Key Locker support for Linux. Intel Key Locker allows for encrypting/decrypting data with an AES key without having access to the raw/actual key. AES keys are converted into handles with Intel Key Locker that can then be used for carrying out encryption/decryption on that system until revoked or system state changes. Intel engineers on Wednesday posted their seventh iteration of the patches for supporting Key Locker on Linux.
