Phoronix

With my review last month of the HP Dev One laptop powered by an AMD Ryzen 7 PRO 5850U and running Pop!_OS I benchmarked it against various laptops I had locally with both AMD and Intel CPUs, including the likes of the very common Tiger Lake SoCs. At the time I hadn't any newer Alder Lake P laptops but now with a Core i7 1280P laptop in hand, here is a look at how that AMD Cezanne Linux laptop can compete with Intel's brand new Alder Lake P SoCs with the flagship Core i7 1280P.

While XWayland is normally used just for running root-less single applications like games within an otherwise native Wayland desktop, new patches from Red Hat that have been merged into the X.Org Server enhance XWayland's existing "root-full" mode of operation for allowing entire desktop environments and window managers to nicely function within the context of XWayland...

As part of the work on the Mesa Radeon Vulkan "RADV" driver, Valve engineers developed the "ACO" compiler back-end that is now used by default for RADV and has shown to deliver better performance at least for RADV than using AMD's official AMDGPU LLVM shader compiler back-end. There has long been talk about adding ACO support to RadeonSI while in recent weeks there has been new code activity on that front...

During the past month there was a lot of exciting Linux kernel activity, the launch of the HP Dev One, never-ending open-source graphics driver advancements, and much more -- in addition to marking Phoronix turning 18 years old. Here is a look back at the June highlights...

Intel on Friday released libva 2.15 as the newest update to the open-source Video Acceleration API (VA-API) library used on modern systems for GPU-accelerated video decoding...

Valve has published a SteamOS 3.3 Beta today for those Steam Deck owners or those otherwise loading this Arch Linux based OS image onto their own hardware...

It's been over a half-year since the last Wayland update with the core code now largely mature, but out today is Wayland 1.21 with the new wl_pointer high-resolution scroll event as well as some smaller additions and fixes...

This month Ubuntu developers have been trying to figure out how to best deal with systemd-oomd on Ubuntu 22.04 LTS killing applications like Firefox during high memory/swap use and that leading to a poor user experience when desktop users not being aware of the situation and suddenly finding their software killed...

Over the many years of covering Coreboot (going back to when it was called LinuxBIOS!) on Phoronix the selection of supported motherboards has been rather unfortunate especially over the last decade. If wanting to run Coreboot on a system today it basically means running a Google Chromebook, using an outdated server motherboard or old Lenovo ThinkPad that has seen a Coreboot port, or out of reach to most individuals are various server motherboards that are reference platforms or board designs from hyperscalers. But over the past several months the folks at the 3mdeb consulting firm have carried out a terrific feat: porting their "Dasharo" downstream of Coreboot to a modern and readily available Intel desktop motherboard. I've been trying this out and it has worked out surprisingly well. Here are my experiences and benchmarks of Coreboot/Dasharo on this Intel Alder Lake motherboard.

Rust 1.62 is out today as the latest update to this popular systems programming language with a few notable changes...

It was on this day in 1992 that Silicon Graphics (SGI) released OpenGL to the world...

Intel has sent in their latest batch of drm-intel-gt-next changes to DRM-Next of their i915 kernel graphics driver changes targeting Linux 5.20. In addition to a lot of code churn still around DG2/Alchemist, the open-source Intel driver for Linux 5.20 is also making more preparations for Ponte Vecchio enablement...

Earlier this month Intel began committing Meteor Lake code to Coreboot for beginning to enable what will be the 14th Gen Core processors under this open-source system firmware solution used by Google Chromebooks and other use-cases. Intel engineers are ending out June with more Meteor Lake enablement code landing ahead of these processors expected to launch in 2023...

The newest member of the Raspberry Pi family is the Pico W and will set you back $6...

To this point Fedora out-of-the-box has been restricted to a filtered subset of Flathub packages when enabled via GNOME Software or GNOME Initial Setup. However, legal has now cleared Fedora for allowing unfiltered/unrestricted access to Flathub, allowing a far greater selection of Flatpaks to become available on Fedora Linux with the plan for this to begin with Fedora 37...

Ubuntu Touch OTA-23 is out today as the newest Ubuntu mobile operating system update for smartphones from the folks at UBports that continues maintaining the code-base left by Canonical and now pushing ahead in their own direction...

Stemming from last weeks Linux kernel patches suggesting an -O3 experimental option for all CPU architectures and Linus Torvalds rather quickly shooting it down, here are some fresh benchmarks looking at the Linux kernel performance when the kernel image is rebuilt with the -O3 optimization level rather than -O2.

AMD has released ROCm 5.2 as the newest version of its open-source GPU compute stack...

For consumer Radeon GPUs the "Radeon Software for Linux" packaged driver version has been on the 22.10 series since the end of March. For AMD Radeon PRO professional/workstation graphics the advertised "Radeon Pro Software for Enterprise on Linux" driver is still the 21.Q4 driver from last December. AMD appears to be finally prepping to release the "22.20" packaged driver as the next feature release to this packaged AMD Linux driver stack for those not relying just on the upstream kernel and Mesa...

The Microsoft Dozen "Dzn" code within Mesa that allows for the Vulkan API to be implemented atop Direct3D 12 for benefit on Windows now has a working pipeline cache implementation...

LLVM release manager Tom Stellard of Red Hat has laid out the planned LLVM/Clang 15.0 release schedule for this next major version of this open-source compiler stack...

Hector Martin who has been leading the Asahi Linux effort for bringing up Linux on Apple Silicon recently received his new 2022 MacBook Pro 13-inch to begin porting Linux to Apple's new M2 SoC. While only started this week, he's already making significant progress. Fortunately, much of the existing M1-written Linux code can work for the M2 but some new drivers will need to be written before the new M2 Macs are fully usable on Linux...

After what has felt like years of neglect and little progress in advancing this open-source mail/communications client, Thunderbird 102 is out today with some shiny new features and a lot of UI refinements...

AMD's GPUOpen team quietly setup a new GitHub repository for "gpurt", presumably a new ray-tracing related software effort...

The Fedora Engineering and Steering Committee (FESCo) has approved a fresh batch of features for the next Fedora Linux distribution release...

With last week seeing AMDVLK 2022.Q2.3 released as an update to AMD's official open-source Vulkan Linux driver and it noting performance improvements, it was time for some fresh benchmarks of that driver up against Mesa's alternative "RADV" Vulkan driver. Here are some fresh benchmarks with an AMD RDNA2 GPU for seeing how RADV continues competing -- and usually outperforming -- AMD's own official open-source driver.

For those not yet on the GCC 11 or GCC 12 stable series, GCC 10.4 is out today as the latest in that older stable series...

A "sched/fair" scheduler change queued this morning into TIP's sched/core for Linux 5.20 aims to enhance the efficiency when searching for an idle CPU under heavy system load. The change led by Intel should improve the kernel's efficiency when the system is overloaded but as with most low-level tuning does run the risk of regressions...

A decade after Luc Verhaegen started the Lima driver effort for reverse-engineering Arm Mali graphics, developers continue occasionally working on improvements to this Gallium3D driver for older generations of Mali hardware. The most recent feature work is finally enabling 4x MSAA support...

Last month for their Vision conference, Intel announced the Habana Labs Gaudi2 accelerator. Gaudi2 is the second-generation offering from Intel-owned Habana Labs for training and inference. The open-source Linux kernel driver support for Gaudi2 is now getting underway along with accompanying open-source user-space software stack support...

Git 2.37 is out today as the latest feature update to this widely-used, distributed revision control system...

The Rust-GCC front-end that allows Rust code to be compiled with the GNU Compiler Collection (GCC) could possibly be upstreamed for next year's GCC 13 compiler release but not necessarily complete at that stage. In any case, it's good seeing progress on Rust-GCC as an alternative to Rust's official LLVM-based compiler...

Merged today to Mesa 22.2 was a four month old merge request for the open-source Radeon Vulkan driver "RADV" that significantly improves the 16-bit FidelityFX Super Resolution (FSR) performance...

Coming about last week was a Fedora 37 change proposal to improve the profiling and debugging of Fedora packages but with possible performance costs. That suggested change is about adding "-fno-omit-frame-pointer" to the default CFLAGS/CXXFLAGS when building packages so the frame pointer is always available for improving the debugging/profiling of the stock Fedora packages. Unfortunately, it can come with significant performance costs as these benchmarks show.

One of Intel's many wonderful open-source projects for creators is OSPRay Studio that is their interactive visualization and ray-tracing application built atop their OSPRay portable ray-tracing engine. OSPRay Studio has been making steady progress since its 2020 debut and out today is their newest update...

The Firefox 102.0 release is now available for download ahead of its stable release announcement tomorrow...

Google engineers are working on the notion of "memory modes" for the Flash-Friendly File-System (F2FS) with the intent on introducing a "low memory" mode for storage devices that would alter its behavior. Presumably Google is working on this new F2FS feature for low-end Android devices...

Linus Torvalds just released Linux 5.19-rc4 as the newest weekly test candidate. There are more patches this week than in the prior Linux 5.19-rc versions but nothing too scary as well as having some notable patches in tow...

Jens Axboe, Linux storage expert and IO_uring lead developer, released liburing 2.2 this weekend as the newest version of this helper library that makes it easier for user-space software to make use of the Linux kernel's IO_uring support...

NVIDIA has contributed support to the FFmpeg multimedia library for being able to take advantage of AV1 GPU-accelerated video decoding by way of the VDPAU API when using the latest-generation NVIDIA RTX 30 "Ampere" GPUs...

Last month Microsoft issued the first production release of CBL-Mariner 2.0, its in-house Linux distribution used for powering services from Microsoft Azure to WSL use-cases and more.

Shotcut remains one of the leading open-source, cross-platform video editors built atop the MLT Multimedia Framework with FFmpeg. Out this week is Shotcut 22.06 as the newest feature update to this non-linear video editing solution...

2022 is certainly looking to be interesting on the open-source graphics driver front... You probably didn't have Imagination publishing an open-source PowerVR Vulkan driver on your 2022 bingo card nor NVIDIA working on an open-source GPU kernel driver. The latest 2022 surprise is the OpenChrome driver project is hoping to finally be mainlined in Linux 5.20 for open-source VIA graphics for those still running vintage VIA x86 hardware...

LLVM developers are eyeing Zstandard "Zstd" use within this compiler stack as a secondary compression method to Zlib. Zstd could be used for compressing ELF debug sections, AST data structures, and other purposes within this open-source compiler stack...
