Back in late 2020 it was originally talked about for Canonical's effort around Snap packages to switch to LZO compression for faster start-up times. Today they published a new blog post on the Ubuntu site highlighting the Snap speed-ups while looking at KDE packages. The LZO-compressed packages are faster than XZ indeed, but still rather a lengthy start-up time for cold apps...

Published at the start of the new year was 2.3k patches providing "fast kernel headers" as a major speed-up to Linux kernel build times and addressing the dependency hell among all the header files in the Linux kernel source tree. It will likely take some time for that massive patch series to work its way to mainline in full, but at least for Linux 5.18 already the patches touching the kernel's scheduler area are ready to land...

Earlier this month AMD began publishing code for their "GFX940" graphics block as a new CDNA GPU, presumably what will be the AMD Instinct MI300 series as their next-gen datacenter GPU. More GFX940 open-source driver enablement work is getting underway...

While there have already been a number of vulnerabilities exhibited for Intel's Software Guard Extensions (SGX) from Prime+Probe to Plundervolt, Spectre-like attacks, SGAxe, and others, it looks like they expect more still to come in the future. Intel engineers are working on the ability for SGX to gracefully handle live CPU microcode updates without a reboot, which these days is increasingly driven for security mitigations and system administrators wanting to apply said updates right away while foregoing downtime...

It's been nearly one year since Microsoft published CBL-Mariner 1.0 as their internal Linux distribution in use at the WIndows company.

For quite a while now the modern AMD Linux kernel graphics driver (AMDGPU/AMDKFD code) has been the single largest driver within the mainline Linux kernel code-base. It's been far larger than the other upstream kernel drivers given the complexities of modern GPUs and is only becoming even larger...

One of the most prominent additions to the Linux 5.17 kernel is the introduction of the AMD P-State driver akin to Intel's P-State driver and aims to deliver better energy efficiency than AMD Zen 2 and newer processors currently on the ACPI CPUFreq driver.

Made public this week was the Spectre-BHB / BHI vulnerability and while only Intel and Arm processors are currently believed to be impacted, in the course of that research the folks at VUSec discovered AMD's current Retpoline strategy for Spectre V2 mitigations is not adequate. This has led to a change in behavior for AMD processors and is already applied to the Linux kernel. Here is a look at what it means for desktop and server performance due to the change in return trampoline handling.

For AMD Navi "RDNA1" GPUs and newer having at least Video Core Next 2.0 (VCN2) for the video coding block, a new feature was merged today into Mesa 22.1-devel for the open-source AMD video acceleration stack...

Linux 5.17 will hopefully be released on Sunday and with that next kernel there are many exciting features in tow.

Back in 2019 that seems like an eternity ago with all that's gone on in the world, the Linux kernel deprecated a.out support. This executable / object code / shared library file format was used prior to the dominance of ELF but is seldom if ever used today. There have been pending patches to finally remove a.out from the kernel while the plan now is to stop building it on Alpha and Motorola 68000 targets to see if anyone notices/cares...

Out today is the first beta release of the upcoming FreeBSD 13.1 operating system update...
