Trend Micro's Zero Day Initiative has uncovered another security issue with the X.Org Server.

SiFive's OpenFive business unit announced today they have completed their first tape out of a RISC-V processor core using TSMC's 5nm process.

For years we have been eager to learn more about the long mentioned Vulkan Video API, which was supposed to come in H1-2020, but now has finally arrived with today's v1.2.175 update in provisional form. The new Vulkan Video extensions allow for GPU-accelerated video encode/decode. The initial public work is treated as a provisional specification and with limited codec coverage but will be expanded upon in time.

Last month Google engineers proposed multi-generational LRU for Linux to enhance the kernel performance and today the work has advanced to a second version.

Vulkan 1.2.175 is now public as the latest Vulkan API specification and it's bringing with it many new extensions.

AOMP 13.0 is out today as the first update to AMD's Radeon OpenMP offloading compiler since AOMP 11.0 last December.

Back in February Slackware 15.0 went into alpha, nine years since Slackware 14.0 made its debut or even five years since Slackware 14.2. Now Slackware 15.0 is up to its beta phase.

In development for more than one year has been the ability to create secret memory areas on Linux that would be visible only to the owning process and is not mapped for other processes or the kernel page tables. That "memfd_secret" system call has finally materialized in Linux-Next and looking like it could be ready for mainline.

Arcan, the long running open-source display server built atop a game engine that has embraced technologies like XR/VR and Wayland and claims feature parity with X.Org this week announced their new Pipeworld project.

Google engineers are responsible for a number of programming languages like Go and Dart while their newest one to be made public is Logica.

NVIDIA announced today in kicking off GTC21 the "Grace" high performance Arm processor for AI and high performance computing workloads. But before getting too excited, this high performance Arm chip isn't expected to be ready until 2023.

More KDE KWin Wayland improvements are coming down the pipe.

While these kernel patches aren't expected to land until the Linux 5.14 kernel cycle later in the summer, a set of 19 patches published on Monday morning begin allowing a test system to boot with the DG1 graphics card.

The MSM DRM driver changes have been sent to DRM-Next for this Freedreno aligned project providing open-source graphics/display driver support for Qualcomm SoCs.

While Intel is often very proactive in adding new CPU families to the open-source GCC and LLVM/Clang compilers where it tends to land a year or more in advance of the processors actually shipping, occasionally there are slipups. Today in fact the "Rocket Lake" support finally was merged into GCC 11 days ahead of that compiler release and after the CPUs were already launched at the end of March.

The Linux 5.12 stable kernel release is quickly approaching but may be challenged by an extra release candidate.

Following the PLATYPUS discovery last year that CPU energy information could be used for possible side channel attacks, the Intel RAPL counters were not only restricted to root but the "amd_energy" driver for exposing CPU energy information on supported Zen series CPUs was also dialed back to root-only in the name of security. Linux 5.13 is introducing a new mechanism so AMD CPUs will be able to still read the energy counters even if not operating as root.

Arguably the most interesting RISC-V board announced to date is SiFive's HiFive Unmatched with the FU740 RISC-V SoC that features four U74-MC cores and one S7 embedded core. The HiFive Unmatched also has 16GB of RAM, USB 3.2 Gen 1, one PCI Express x16 slot (operating at x8 speeds), an NVMe slot, and Gigabit Ethernet. The upstream kernel support for the HiFive Unmatched and the FU740 SoC continues.

While EXT4 supports both case-folding for optional case insensitive filenames and does support file-system encryption, at the moment those features are mutually exclusive. But it looks like the upcoming Linux 5.13 kernel will allow casefolding and encryption to be active at the same time.

The LuxCoreRender open-source physically based rendering (PBR) software is out with its latest major feature release that now offers NVIDIA OptiX/RTX acceleration support alongside the existing CPU, NVIDIA CUDA, and OpenCL rendering paths.

It's been another week of fixes and feature work for the KDE desktop as the march continues toward the Plasma 5.22 release this summer.

If your current Vulkan-based Radeon Linux gaming performance isn't cutting it and a new GPU is out of your budget or you have been unable to find a desired GPU upgrade in stock, the Mesa RADV driver has added an option likely of interest to you... Well, at least moving forward with this feature being limited to RDNA2 GPUs for now.

Wine 6.6 is out as the open-source project's first release of April for running Windows games and applications primarily on Linux and macOS platforms. With Wine 6.6 comes more feature work that will ultimately be incorporated into the Wine 7.0 release due out in early 2022.

The NVIDIA-led work to allow XWayland OpenGL and Vulkan acceleration with their proprietary driver has just been merged into X.Org Server Git.

The upcoming release of Fedora 34 will make it the first major Linux distribution to have sevctl available, an open-source utility for managing AMD EPYC systems with Secure Encrypted Virtualization (SEV).

The latest open-source compiler infrastructure effort seeking to target a wide spectrum of devices from CPUs through GPUs, FPGAs, and accelerators is HPVM. The HPVM project today celebrated its 1.0 milestone.

FFmpeg 4.4 is out today as a large update to this widely-used multimedia library and with it comes many new features including new demuxers, AV1 support improvements, and other enhancements.

The ability to randomize the kernel stack offset at each system call looks like it will land for the upcoming Linux 5.13 cycle. This optional feature makes it much more difficult to carry out stack-based attacks on the Linux kernel.
