Just weeks ahead of the GCC 11 stable release we saw Znver3 tuning work out of SUSE for allowing the GNU Compiler Collection to better cater towards the AMD Zen 3 microarchitecture. That tuning work follows the initial patch at the end of last year that introduced "Znver3" and flipped on the new instructions . Now another patch working on the Zen 3 tuning for GCC has been posted and already merged.

Jan Hubicka of SUSE has been the one working on this AMD Zen 3 tuning support for GCC 11 that

OpenBLAS 0.3.14 is out today as the newest version of this open-source BLAS (Basic Linear Algebra Subprograms) library that continues to work on maximizing the performance for x86_64 and other architectures.

OpenBLAS 0.3.14 on the x86_64 has an optimized BFloat16 GEMM kernel for Intel Cooper Lake processors, auto-detection is added for Rocket Lake and Tiger Lake, and AMD Ryzen processors are enjoying improved performance for SASUM / DASUM /

Audacity 3.0 is out today as a big update to this popular, longtime open-source digital audio editor.

Audacity 3.0 is a big update over the Audacity 2.4 series in that it overhauls its project file format. Rather than the pile-of-files approach for managing assets being dealt with inside an Audacity project, the new "AUP3" file format will store all project elements within that single file.

This fundamental change should lead to less confusion by users over what file(s

With no one willing to step up and manage the X.Org Server 1.21 release and see it through for maintenance, Red Hat engineers who often managed those xorg-server releases are now moving ahead with standalone XWayland releases with that code pulled out of doing a full X.Org Server release and instead isolated to the XWayland bits for handling of X11 clients under Wayland. Today marks the inaugural release with XWayland 21.1.0.

XWayland 21.1 is out today as the

With still no sign of BUS1 on the horizon for the mainline kernel or any other successor to BUS1 or KDBUS for in-kernel IPC, Dbus-Broker remains the best bet currently in 2021 for a more performant D-Bus implementation while retaining compatibility with the D-Bus reference implementation.

Dbus-Broker continues evolving as the high performance D-Bus message broker developed by many of the same BUS1 and systemd developers from Red Hat. Red Hat's David Rheinsberg today released Dbus-

The developers working on the RADV open-source Radeon Vulkan driver for Mesa are relentless in their quest for delivering optimal performance. Hitting Mesa 21.1 today were another set of patches for enhancing the MSAA anti-aliasing performance for GFX10 (Navi 1x / Navi 2x) graphics cards.

With this MR to allow skipping FMASK decompressions, Vulkan games making use of multi-sample anti-aliasing (MSAA) should see around 1~2% faster performance with the current Navi and newer GPUs.

It was less than one month ago that Valve developers added a new "single file" cache option for Mesa as an alternative to its existing multi-file cache. Valve now with their latest Steam for Linux beta is supporting this new single-file cache for faster performance.

The Mesa single file cache can help for on-disk space savings, compared to the existing Mesa on-disk shader cache taking up as much as 3x the space of the single file cache. The single file cache also makes it easier

Coincidentally on the same day as formally announcing Rocket Lake S , Intel's open-source driver engineers have sent in their next-gen "Rocket Lake S" enablement code to DRM-Next for landing this spring in the Linux 5.13 merge window.

A big batch of Intel kernel graphics driver code was sent in as a pull request on Tuesday for DRM-Next ahead of the Linux 5.13 merge window, which should be opening around the end of April and then releasing as stable this
