Latest Linux Hardware Reviews, Open-Source News & Benchmarks

The soon-to-be-released openSUSE Leap 15.5 was going to be the last of the openSUSE Leap 15 series, but now openSUSE/SUSE has decided there will be an openSUSE Leap 15.6 release to allow additional time for their Adaptable Linux Platform (ALP) to be developed.

Dav1d 1.2.1 was released and while the version number may not be significant, it does have some useful performance optimizations and other tuning for this CPU-based open-source AV1 video decoder.

A few new AMD heterogeneous system patches have been queued via TIP.git ahead of the upcoming Linux 6.5 kernel merge window. These newest AMD Linux patches are focused on proper heterogeneous system enumeration for AMD data center systems sporting the Instinct MI200 and newer accelerators.

David Airlie has managed to hack together task/mesh shader support inside Lavapipe, the CPU-based software Vulkan implementation inside Mesa.

As a win for AMD Ryzen Linux systems for greater performance and power efficiency, AMD is ready to set their P-State driver's default operation mode to be the recently merged "active" mode for Ryzen laptops and desktops.

Due to not having sent in any feature pull requests to DRM-Next in prior weeks due to a miscommunication, sent out today was a bit set of Intel "i915" kernel graphics driver changes targeting this next kernel cycle.

Today marks nineteen years since I started Phoronix.com for covering the Linux hardware space. It's been a wild ride from the days of 56K modems, graphics driver pains, and having to use NDISWrapper for WiFi device driver support on Linux, among many other Linux hardware pains in the early days. These days the open-source GPU driver scene is far better off, Linux hardware support overall is great, companies continue investing massively into Linux/open-source thanks to the success in the server space over the past two decades, and the Steam Deck has proven to be one of the most interesting Linux-powered consumer devices in recent years.

Following last week's release of Chrome 114, Mozilla developers today uploaded the release binaries for Firefox 114 ahead of tomorrow's official announcement.

Codeplay Software, which was acquired by Intel last June, has an exciting announcement to make today in the form of the oneAPI Construction Kit. This open-source project aims to help ease bringing up SYCL on new processor/accelerator architectures, particularly around HPC and AI. The oneAPI Construction Kit also has a reference implementation for RISC-V.

Last month Linux's sound subsystem maintainer Takashi Iwai published a set of Linux driver patches for MIDI 2.0 support for the USB Audio and Raw MIDI drivers. That roughly six thousand lines of new code for the MIDI 2.0 driver coverage is now expected to be mainlined with the upcoming Linux 6.5 cycle.

For those running HP or HP-Compaq business-class systems whether they be desktops or laptops, improved hardware sensor reporting is expected for the upcoming Linux 6.5 kernel thanks to a new HP WMI Sensors driver set to be mainlined.

The open-source uutils project that is striving to be a drop-in replacement to GNU Coreutils but written within the Rust programming language is out today with a new feature update.

For fans of the lightweight IceWM X11 window manager, released on Sunday was IceWM 3.4 as the newest feature release.

Debian 12 remains on track for releasing next week even with around 100 known RC bugs that likely won't be resolved pre-release. The Debian release team says overall things are on-track.

Linus Torvalds just released Linux 6.4-rc5 as the latest weekly test candidate for Linux 6.4 and this kernel version is looking to be in good shape for a likely release in late June.

The LLVM Fortran compiler "Flang" has begun seeing NVIDIA CUDA support land in the upstream code-base.

The ACO "Amd COmpiler" started by Valve for the Mesa RADV Vulkan driver has shown it can do wonders for Linux gaming performance and reducing game load times compared to AMD's official AMDGPU LLVM shader compiler back-end. Recently thanks to the work of Qiang Yu there has been much work hitting upstream Mesa for beginning to enable using the ACO compiler by the RadeonSI Gallium3D driver.

With Chrome 114 is the start of Google beginning to roll-out Maglev as their new mid-tier compiler for further enhancing the JavaScript browser performance.

A new set of patches this weekend begin laying the groundwork for Rust abstractions for Linux network device drivers so that Rust code can be used for constructing new network device drivers. The patches also include a dummy Rust network driver.

One of the most interesting aspects of the new AMD Ryzen 7040 series laptop processors is the new "Ryzen AI" capabilities with the new XDNA AI engine capabilities built into the SoC, leveraging IP from their Xilinx acquisition. Linux support details remain scarce but at least one of their (Windows) demos for showcasing Ryzen AI is open-source.

On Friday a big set of patches affecting the AMDGPU/Radeon/AMDKFD kernel drivers were submitted for DRM-Next to queue until the Linux 6.5 kernel merge window opens in the coming weeks. A lot of new feature code is part of this pull for benefiting new hardware, continuing to refine AMD GPU power management under Linux, and more.

With Intel TDX and AMD SEV-SNP for better securing virtual machines on the mainline Linux kernel, memory is accepted/initialized immediately at boot time by the VMs although the capability exists to have "unaccepted memory" where that memory is only dealt with by the VMs later on or on an as-needed basis. For two years now Intel engineers have been working on this unaccepted memory support and this week posted their thirteenth iteration of these fundamental Linux kernel patches.

The Portable Computing Language "PoCL" began as an open-source CPU-based OpenCL implementation that has become quite a comprehensive implementation over the years. But in leveraging the LLVM/Clang compiler stack, over time PoCL has grown beyond just a CPU implementation to also support OpenCL execution on NVIDIA GPUs, AMD HSA-capable GPUs, and more. The latest now coming with PoCL 4.0 is support for Intel Level Zero execution for running this OpenCL implementation over Intel Arc Graphics GPUs.

Serpent OS started out as a new Linux distribution started by Ikey Doherty, the same developer that rose to fame for starting the Solus Linux distribution prior to a hiatus. Serpent OS was getting off the ground when the surprise full-circle announcement came in April that Solus Linux would build off Serpent OS.

KDE developer Nate Graham began his weekly development recap by noting that Plasma 6.0 development continues and its stability is improving daily as well as seeing new features.

On Monday, 5 June, will mark 19 years since I started Phoronix.com to focus on Linux hardware reviews.

Linux laptop/desktop vendor System76 has made some improvements to their Coreboot open firmware offerings to benefit their latest Intel Core 13th Gen "Raptor Lake" wares as well as prior generation devices.

Red Hat has decided they will be doing less work on desktop applications and will stop shipping LibreOffice as part of a future Red Hat Enterprise Linux release (presumably RHEL10). This is also limiting Red Hat's engagement in working on LibreOffice packaging for Fedora while the hope is that the Flatpak'ed LibreOffice will fill the void.

It's almost a daily occurrence to find interesting Linux kernel patches (and to other open-source projects too!) by Intel's large cabal of open-source engineers. The latest crossing my radar is for allowing the Linux "intel_idle" driver to run inside virtual machine (VM) guests.

The Linux 1-Wire "w1" subsystem is used for supporting drivers with hardware that communicates via a single wire (plus ground) in a simple master-slave configuration The Linux kernel has drivers such as for W1 over GPIO, i2c to W1 bridge, and supporting some very old hardware. The W1 subsystem hasn't seen much work recently while for the upcoming Linux 6.5 cycle will be seeing a larger update.

By pairing Wine and QEMU, Hangover continues as one of the open-source projects working to allow Windows games/apps run on other architectures like AArch64 and potentially POWER, RISC-V, and others too.

The Freedreno Gallium3D driver within Mesa 23.2-devel is now able to expose OpenGL 4.6 support for Qualcomm's Adreno 600 series graphics processors.
