A small but measurable and seemingly widespread performance optimization is currently being buttoned up for Intel's open-source "ANV" Vulkan driver within Mesa to benefit latest-generation Gen12/Xe Graphics...

For those running Linux MD RAID10 arrays you may have found the performance around discard requests such as when running MKFS and FSTRIM operations to be rather slow... Well, with Linux 5.13 it will be lightning fast...

Google's open-source SwiftShader has been supporting a software-based Vulkan implementation for some time, building off its prior OpenGL / GLES and D3D9 support. While SwiftShader's Vulkan implementation has received heavy investment and attention from Google, it turns out Mesa's Lavapipe software implementation is beginning to pull ahead...

Intel's latest addition to Mesa 21.1 with their "ANV" Vulkan driver is... A null hardware layer...

Besides Valheim, there hasn't been much in the way of native Linux game releases recently to really get excited about with much of the activity these days being through Valve's Steam Play for running Windows games on Linux. But in April there will be at least two high profile native Linux game releases...

This week marked the hard feature freeze for QEMU 6.0 along with the tagging of QEMU 6.0-rc0. The QEMU 6.0 release should happen around the end of April for this important piece of the open-source Linux virtualization stack...

Launched last week with the AMD EPYC 7003 "Milan" processors was the AOCC 3.0 code compiler as AMD's downstream of LLVM Clang with various patches now catering to optimized for Zen 3. Last week some preliminary benchmarks of AOCC 3.0 on the Ryzen 9 5950X were carried out to good results. Since then I have begun putting AOCC 3.0 through its paces on a AMD EPYC 7003 series server to overall great results.

Panfrost has been the Gallium3D driver providing open-source OpenGL for Arm Mali Bifrost and Midgard GPus while now "PanVK" is in development as an open-source Vulkan driver...

While Intel is well known and loved for their generally very timely open-source hardware enablement under Linux, occasionally there are exceptions to that long-standing tradition of having the support squared away ahead of product launches. One of the areas where Intel has been slow at enabling their open-source Linux support is around their Gaussian and Neural Accelerator (GNA) but that driver is now coming together for being mainlined hopefully in the near future...

Besides Linux kernel developers still working to optimize code due to Retpolines overhead three years after Spectre rocked the ecosystem, another area kernel developers have still been actively working on is core scheduling for controlling the behavior of what software can share CPU resources or run on the sibling thread of a CPU core. That core scheduling work is finally closer to the mainline Linux kernel...

The Generic USB Display Driver "GUD" has just been sent in as part of the latest DRM-Misc-Next material to DRM-Next which in turn will land for Linux 5.13. The Generic USB Display Driver is nifty and allows for opening up possibilities like turning a Raspberry Pi Zero into a USB to HDMI display adapter among other fun use-cases...

When it comes to open-source Arm Mali graphics on Linux, the Panfrost Gallium3D driver is what's talked about the most given that it's for supporting newer generations of Mali graphics hardware. But the Lima Gallium3D driver effort remains ongoing for supporting older Mali 400/450 series hardware...

AMD has been offering SEV "Secure Nested Paging" patches via a GitHub repository while now they are working towards mainlining this feature for the Linux kernel...

While the RadeonSI Gallium3D open-source OpenGL driver for Linux systems is very well received and generally outperforming the proprietary AMD OpenGL driver on Linux/Windows and performing very strong against NVIDIA's proprietary OpenGL driver too, it's not game over for this older graphics API and AMD is still working to lower the CPU overhead even further for this open-source code...

The big GNOME 40 desktop update is now available...

AMD today released their Radeon Pro Software for Enterprise 21.Q1 driver packages for Windows and Linux systems...

Raised during the recent discussion over looking at removing Mesa's classic drivers from the mainline tree this year is that there still exists an effort trying to create an Intel Gallium3D driver for older pre-Broadwell graphics currently only served by the i965 classic driver. That Crocus effort continues to be worked on but isn't yet mainline...

AOMedia libaom 3.0.0 was released on Tuesday by Google engineers as this reference AV1 video encoder...

While Microsoft often likes to proclaim their "love" for Linux, it's been independent open-source developer Maximilian Luz that has been spearheading improvements for Microsoft Surface devices on Linux. With Linux 5.13 his latest work on better handling Microsoft Surface device detachment handling should land...

Right now when it comes to Motorola 68000 "m68k" emulation with Linux the most powerful target is the Quadra 800 that is limited to just 1GB of RAM and specific interfaces. But on the way is the new "Virtual M68k Machine" that is much more powerful...

They are a bit late in doing so, but Ubuntu developers are working to figure out if it makes sense to run FSCK "file-system check" at boot time. It turns out Ubuntu Server and other Ubuntu installations making use of their Curtin installation component haven't enabled the functionality for FSCK at boot but now they are (re)visiting the matter...
