The open-source WinGet package manager is approaching three years since its announcement while it continues to not be as rich and robust of what Linux users for many years have enjoyed, but in any case it's continuing to be improved...

There still is another month to go until the Linux 6.2 kernel is released as stable and in turn kicking off the Linux 6.3 merge window. But from my monitoring in recent weeks, here is an early preview of some of the material expected for the v6.3 kernel based on what's been queuing in the various subsystem "-next" branches or otherwise looking like it should align for the next cycle...

With this weekend's release of helloSystem 0.8 as a macOS-inspired open-source desktop OS built atop FreeBSD, I decided to try out this new release on an AMD Ryzen 9 7950X desktop to see how it would go.

Intel Sandy Bridge processors launched 12 years ago this month and if you still are relying on these 32nm CPUs, it's really time to consider an upgrade for not only the performance but also security and power efficiency reasons. But if you are content with still churning away on a Sandy Bridge desktop under Linux, picked up for upstream and marked for back-porting is another attempt at dealing with visual glitches and GPU hangs that have been affecting some users with the integrated graphics...

The Ubuntu xx.04.2 LTS releases tend to be a bit more meaningful for long-term support users since it includes the back-ported hardware enablement "HWE" stack with updated Linux kernel from the newer non-LTS release. Ubuntu 22.04.2 LTS had been due for release on 9 February with that updated stack but is now pushed back to the end of the month over technical issues...

As I wrote about earlier this week, Linux 6.3 is positioned to support AMD Zen 4's Automatic IBRS feature. AMD's Linux enablement code around Automatic IBRS has been undergoing review the past few months and now via TIP's x96/cpu Git branch is to be sent in next month for the Linux 6.3 merge window. I've run some preliminary benchmarks of the Automatic IBRS support on Zen 4 and it's looking positive for further enhancing the performance of AMD's new Ryzen 7000 series and EPYC 9004 series processors.

With last week's launch of Intel's 4th Gen Xeon Scalable Sapphire Rapids server processors, Intel heavily talked up the shiny new accelerators and the big performance potential of AMX, but not really showcased and only heard through the grapevine was the improved AVX-512 implementation found with these new processors. With Sapphire Rapids there is reduced penalties from engaging AVX-512 -- and for some AVX-512 instructions, no longer any measurable impact -- compared to prior generation Xeon processors. In this article is a look at the performance for a wide variety of workloads with AVX-512 on/off not just for Sapphire Rapids but also for prior generation Ice Lake as well as AMD's new EPYC 4th Gen "Genoa" processors where they have introduced AVX-512 for the first time.

Last month a change proposal was filed for aiming to yield faster reboots and shutdowns of Fedora Linux by shortening the time window that services can block the shutdown process. A modified version of that change proposal has now been cleared by the Fedora Engineering and Steering Committee...

With AMD Zen 4 processors there is a new Automatic IBRS (Indirect Branch Restricted Speculation) similar to Intel's Enhanced IBRS (eIBRS) functionality for offering lower-overhead Spectre V2 mitigations compared to the Retpoline approach used on Zen 3 and prior. Finally with Linux 6.3 that Auto IBRS support is now set to be merged...

Over the past year NVK has taken shape as a -- currently out-of-tree -- Mesa Vulkan driver for supporting NVIDIA graphics hardware. This open-source NVIDIA Vulkan driver is inching closer to the point of being upstreamed into Mesa, but before it's usable for gamers/enthusiasts there is kernel work that must happen too...

One of the exciting announcements Intel made just before Christmas was announcing their work on the new "Xe" kernel graphics driver for Linux. This new Direct Rendering Manager (DRM) driver will eventually replace the long-standing i915 kernel driver when it comes to handling Gen12 integrated and discrete graphics as well as future Intel graphics hardware...

The Windows game Control that runs via Valve's Steam Play no longer needs the RADV_PERFTEST=rt environment variable override to enjoy the ray-tracing support but with Mesa 23.1 (and potentially backported for 23.0) will work out-of-the-box...
