Intel this week is using Computex 2023 to make some disclosures around next-generation Meteor Lake processors for laptops. The most exciting aspect relayed in advance during our press briefing last week was that all Intel Meteor Lake processor SKUs will feature their new Vision/Versatile Processing Unit.

As a step toward further improving AMD laptop support under Linux, AMD engineers have been working on WiFi radio frequency interference (RFI) mitigation support for Linux with their latest laptops.

As a temporary workaround for helping recent versions of Cyberpunk 2077 to run on Linux under Valve's Steam Play with Intel Arc Graphics, Intel's open-source Mesa driver is temporarily no longer identifying as "Intel" graphics via its graphics vendor ID in order to workaround an issue.

System76 continues teasing the in-house laptop design they are working on codenamed Virgo.

Last week XFS users began encountering metadata corruption on the latest Linux 6.3 point releases. Following kernel developers and those testing the kernels on affected hardware over the US holiday weekend, it's believed the issue has been tracked down to one missing patch that is a one line of code being deleted.

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.

While GCC 13 saw its first stable release several weeks back, for those taking their time in moving to major new compiler releases and still relying on the two-year-old GCC 11 series, out today is the GCC 11.4 point release.

Vulkan 1.3.251 is out today as a rare Sunday morning spec update for this Khronos graphics/compute API.

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.

Following the release of Wine 8.9 on Friday for enabling Windows games and applications to run on Linux, Wine-Staging 8.9 is now available for this more testing/development-focused flavor of Wine that more liberally picks up in-development patches.
