A pending change to the Mesa Radeon Vulkan driver "RADV" is leading to much lower system RAM use for some games that make use of many Vulkan Graphics Pipeline Libraries (GPL). The game causing this issue to be investigated was Valve's Dota 2 on RADV and is now seeing an 85% reduction in system RAM use by this open-source Radeon Linux driver.
Ubuntu Touch as the community maintained version of Ubuntu Linux for smartphones and tablets has for years been frustratingly limited to Ubuntu 16.04 LTS as its base operating system for when Canonical had abandoned their smartphone ambitions. Today though that has finally changed with Ubuntu Touch OTA-1 Focal having been released that moves things forward to an Ubuntu 20.04 LTS base.
Back in October Google announced their Compute Engine C3 instances in private preview that featured 4th Gen Xeon Scalable "Sapphire Rapids" processors as well as making use of Google's custom Intel Infrastructure Processing Unit (IPU). Since then, back in January, was the big Sapphire Rapids launch with the likes of the Xeon Platinum 8490H being released. Last month meanwhile Google promoted the C3 VMs to public preview state. The Sapphire Rapids C3 VMs remain in "public preview" from Google Cloud during which time there are no charges involved for the CPU costs. For those wondering about the core-for-core performance of Sapphire Rapids in Google Cloud, here are my initial benchmarks of the C3 series.
Going back to late 2021 was the initial GCC compiler patch for "Ampere-1" for that next-gen AArch64 server processor while last year this successor to Ampere Altra (Max) was formally announced under the AmpereOne brand. That initial compiler support appeared in GCC 12 while ahead of the GCC 13 release in the coming weeks has been some last minute tuning for the AmpereOne cost table.
Thanks to forthcoming work out of Red Hat, the Linux 6.4 Device Mapper (DM) code is expected to see some optimization work that can significantly benefit concurrent I/O performance... In one case at least acquiring buffers now about 25 times faster.
While XWayland is in fairly good shape for enjoying both native and emulated games relying on X11 to run atop Wayland compositors for Linux gaming, occasionally different peculiar issues are uncovered. The most recent issue analyzed and addressed in XWayland Git is over the game Resident Evil 6 causing XWayland to hang and consume 100% of the CPU resources on launching that title.
In time for OBS Studio 29.1, the Veovera Software Organization non-profit has contributed support for AV1 and HEVC streaming via RTMP so that gamers and other creators can stream their content to the YouTube RTMP server using these newer video formats.

OpenMandriva ROME 23.03 has been released as the "rolling release" flavor of this Linux distribution whose roots trace back to the beautiful days of Mandrake Linux.
With the Linux 6.2 release kernel developers addressed "a tasty target for attackers" after it was realized that the per-CPU entry data was not being randomized, even in the presence of Kernel Address Space Layout Randomization (KASLR). The per-CPU entry area randomization has been present since Linux 6.3 but then was realized it's being activated even if KASLR was disabled, so now that is changing to avoid possible confusion.
Rob Clark on Saturday sent out a pull request adding the DMA-BUF/DMA-FENCE deadline awareness code to the Direct Rendering Manager (DRM) subsystem with the upcoming Linux 6.4 cycle.
Merged this weekend to the LLVM 17 development code-base is initial support for RISC-V's vector crypto extension ISA.
José Expósito announced the release this weekend of libinput 1.23, the input handling library used these days across the Linux desktop for both X.Org/X11 and Wayland based environments. With libinput 1.23 comes a few notable new features.
KDE developers remain quite busy working on Plasma 6.0 development along with preparing fixes for further Plasma 5.27 LTS point releases.

AMD on Friday sent out new patches for enabling some new graphics IP "blocks" as part of their block-by-block enablement strategy they've been using to introduce new GPU support to their Linux graphics stack by focusing on smaller patch series with versioned parts of the GPU rather than big monolithic patch series with colorful fishy codenames.

AMD has been teasing FidelityFX Super Resolution 3 (FSR3) as the latest version of their game upscaling tech that will be released later in the year. AMD began showing off FSR 3 to game developers this week at GDC while also re-affirming their open-source commitment.
Recently I provided a fresh look at the Intel Arc Graphics Linux gaming performance with the newest open-source drivers. While it was a letdown with some of the newer Steam Play games still not working due to current limitations of the Intel "ANV" open-source Vulkan driver and some Vulkan performance issues in other titles, one area that stood out was the very good Linux OpenGL performance. That made me curious to look at the workstation OpenGL performance for Intel Arc Graphics, which is the focus of today's testing.
Not to be confused with Valve's downstream, VKD3D-Proton, that is used by Steam Play but Wine's VKD3D codebase itself is out today with a new version of this Direct3D 12 on Vulkan implementation.
