A Linux fix is on the way for a new quirk to address an issue whereby some AMD Radeon graphics cards have an issue with the resizable BAR (AMD Smart Access Memory) handling that could lead to lower performance...

Proton Experimental 5.13-20210107 is out today as the first 2021 release of this Wine downstream that powers Steam Play for running Windows games on Linux...

Following last month's initial benchmarks of the AMD "znver3" support that landed in the GCC 11 compiler was a request by a premium supporter to see the AMD Zen 3 benchmarks at more compiler optimizations. Well, here are those numbers for those wanting to pursue aggressive compiler optimizations on a shiny AMD Ryzen 9 5950X.

While Intel is generally well regarded for their Linux development practices especially as it pertains to continuous integration and their test labs for vetting code prior to reaching the mainline Linux kernel to minimize the risk of regressions or other unintended side effects, those running older Haswell GT1 low-end graphics have seen the past several kernel versions going back a half-year yield a GPU hang at boot...

Intel has released their High Performance Computing Reference Stack 2.0 as the latest Docker image optimized for HPC/AI workloads...

Alyssa Rosenzweig who is known for her work on reverse-engineering Arm GPUs and in particular the multi-year effort so far working on the Panfrost open-source driver stack has taken up an interest in Apple's M1 graphics processor...

The GNOME Shell user experience improvements and other components continue in development at full-speed for the GNOME 40 release due out in March...

NVIDIA today released the 460.32.03 Linux graphics driver as their first stable release in the 460 driver series...

The Intel-developed IWD Linux wireless daemon is out with its first feature release of 2021...

Surprisingly it has taken until 2021 but the RadeonSI Gallium3D OpenGL driver now supports using the company's own Radeon GPU Profiler...

NVIDIA's Wayland support is finally coming together albeit long overdue with DMA-BUF passing support and now patches pending against XWayland for supporting OpenGL and Vulkan hardware acceleration with their proprietary driver...

The release of Fedora 34 this spring is now cleared to enable systemd-oomd by default for all spins in an effort to enhance the out-of-memory / memory pressure experience on Linux...

It was just at the end of December that the Mesa 21.0 development code enabled OpenGL 3.2 support for Freedreno, the open-source Gallium3D driver for Qualcomm Adreno graphics hardware. Now in time for Mesa 21.0 still, OpenGL 3.3 support has been achieved...

Linux 5.10.5 LTS is out today with at least one rather interesting addition...

With this week marking three years since Spectre and Meltdown were made public in ushering in a wave of CPU security disclosures that followed and mitigations that often resulted in measurable performance hits, here is a look at how the performance costs stand today with various new and older Intel CPUs as well as AMD processors too. This article is looking at the current performance costs under Linux with the default mitigations and then the run-time disabling of the relevant mitigations for each of the processors under test while using an up-to-date Ubuntu 20.10 paired with the new Linux 5.10 LTS kernel.

AMD has begun staging their new open-source driver code ahead of the next AMDVLK driver release that will likely occur this week or next. With this latest AMDVLK code dump, there is easy run-time switching support between the AMDVLK and RADV Vulkan drivers...

Released at the end of November was the much anticipated OpenZFS 2.0 open-source ZFS file-system implementation for Linux and FreeBSD systems. Today that has been succeeded by OpenZFS 2.0.1 with support for newer Linux kernels and many bug fixes...

Yet another big change being eyed for Fedora 34 is to sign individual files within shipped RPM packages. The signatures will use the Linux Integrity Measurement Architecture (IMA) and in turn can be used to enforce run-time policies around only allowing the execution of trusted files...

With Linux 5.12 the Broadcom BCM2711 SoC used by the Raspberry Pi 4 will see 10 and 12-bit color support with the VC4 Direct Rendering Manager driver...

Google engineers continue working on the Linux kernel around "Restricted DMA" for helping to protect systems that lack DMA access control for hardware without an IOMMU...
