Landing today in the RadeonSI Gallium3D driver code-base for Mesa 22.2 is support for the EGL_IMG_context_priority extension. The RadeonSI EGL_IMG_context_priority support was contributed by a KDE developer with the motivation of ensuring Wayland compositors can have high priority for rendering...

Way back in 2019 the Linux kernel deprecated a.out support given that it was superseded by ELF, which itself has already been supported for over two decades going back to Linux 1.x kernels. With Linux 5.19, the obsolete 32-bit x86 a.out support is finally being removed for good from the kernel...

The power management, ACPI, and thermal control updates are ready for Linux 5.19. This cycle there is a lot of PM/thermal work as usual on the Arm side while Intel also continues with a lot of changes from new hardware support to improving overheat handling of laptops for S0ix handling...

Bavarian PC vendor TUXEDO Computers that specializes in various Linux pre-loaded notebooks and desktop computers recently launched their Aura 15 Gen2 laptop focused on being an "affordable business allrounder" and powered by AMD Ryzen 5000 series processors with integrated Vega graphics to make for a nice open-source driver experience. TUXEDO sent over the Aura 15 Gen2 for a round of testing and here's a look at this Ubuntu Linux laptop's performance and capabilities.

It was over a year ago that AMD initially added the "GFX90A" target to their LLVM AMDGPU compiler back-end while now this week added to the GNU Compiler Collection for the GCC 13 release not due out until next year is its GFX90A support for the GNU toolchain...

David Airlie this morning sent in the Direct Rendering Manager (DRM) subsystem updates for the Linux 5.19 merge window. Most notable with the DRM display/graphics driver updates for this next kernel version is a lot of work on Intel Arc Graphics DG2/Alchemist in getting that support ready plus initial Raptor Lake enablement. as well as AMD preparing for next-generation CDNA Instinct products and RDNA3 Radeon RX 7000 series graphics cards...

It's been five years already since Red Hat started Stratis as a configuration daemon built atop LVM and XFS in aiming to provide advanced storage functionality in user-space akin to what is offered by the advanced Btrfs and ZFS file-systems...

The 64-bit Arm (AArch64) architecture changes have been merged into the in-development Linux 5.19 kernel...

Security researcher Jason Donenfeld known as the founder of the WireGuard project has recently been focused on modernizing the Linux kernel's random number generator (RNG/random) code. With the Linux 5.19 kernel there is yet more work landing...

David Sterba of SUSE has submitted the ~4k lines of code worth of feature changes for the Btrfs file-system driver in the Linux 5.19 kernel...

Google just promoted Chrome 102 to stable as the latest feature update to their cross-platform web browser...

The Linux x86/x86_64 kernel has long honored the "clearcpuid=" kernel parameter to disable select CPUID features from being used by the kernel or readily advertised. However, it hasn't been very intuitive to use since it relied on passing the bit numbers for the specific features. With Linux 5.19 it's much easier to deal with in now allowing the CPUID string from /proc/cpuinfo to be passed if wanting particular CPUID features disabled...

Vulkan 1.3.215 is out today with a handful of fixes/clarifications to the Vulkan specification plus one new extension...

Nginx as the lightweight web-server known for its speedy performance is out today with the version 1.22 feature release...

In recent kernel versions there has been an uptick in new driver activity around improving hardware sensor monitoring support for AMD/Intel desktop motherboards, but still it's generally behind that of the support found under Microsoft Windows. With Linux 5.19 there is more hardware monitoring "HWMON" subsystem work with improving sensor coverage on various motherboards and other components...

Mir 2.8 is now available as the newest feature update to this Wayland compositor developed by Canonical for various Ubuntu use-cases, primarily around IoT, digital signage, and similar fields...

At the end of last year Amazon announced their new Graviton3 processors with around 25% more compute performance than their prior Graviton2 AArch64 processors, up to 2x the FP and crypto performance, DDR5 system memory support, and other improvements to their in-house processor for the AWS cloud. Yesterday the C7g instances reached general availability for making Graviton3 processors available to AWS customers. Here are some initial benchmarks.

Among many Intel driver improvements in Linux 5.19, Intel's new "In-Field Scan" (IFS) driver has now premiered in the mainline kernel for testing future processors against any silicon issues prior to deployment or as the processors age...

What started out as hopes of enabling RADV ray-tracing by default has led to initially ray queries being enabled by default...

Intel's Software Guard Extensions (SGX) as security-related extensions to their processors that allow for protected memory enclaves has had a rather bouncy journey. Intel continues supporting SGX on their latest Xeon processors but on the client side have been deprecated since 11th Gen Core. Over the years SGX has been found vulnerable to various attacks from speculative execution exploits to Plundervolt. It also turns out under Linux until now was also open to crashing under memory pressure...
