While just a day prior Linus Torvalds was questioning the proposed "HTE" subsystem, today on this final day of the Linux 5.19 merge window he decided to land this new subsystem...

Greg Kroah-Hartman on Friday sent in the USB/Thunderbolt updates for the Linux 5.19 kernel that is seeing its merge window end today. With the USB updates, Greg had some remarks on the DWC3 Linux driver that will likely "never be finished" given that this USB IP is appearing in lots of hardware but not consistently being implemented and thus continuing to require a lot of adaptations on the driver side...

Last month Microsoft published their first production release of CBL-Mariner 2.0 as an updated version of their in-house Linux distribution used for a variety of purposes from Windows Subsystem for Linux to Azure. This week Microsoft released a rather hefty stable update to their CBL-Mariner 2.0 distribution...

Greg Kroah-Hartman on Friday submitted the "char/misc" changes for the Linux 5.19 kernel. Char/misc continues to be the "catch all" area of the kernel for drivers and code not fitting formally within other kernel subsystems. Leading on this front for Linux 5.19 is the introduction of the Apple eFuse driver for M1 systems and Intel-owned Habana Labs continues improving their AI accelerator driver...

FEX-Emu 2206 has been released as the newest version of this user-space, open-source software for being able to run x86/x86_64 applications and games on AArch64 (Arm) hardware...

While there has been progress with the Mesa code targeting Apple M1 to run basic tests like glmark2, that has traditionally been an effort running under macOS with its kernel driver. This week the Asahi Linux crew celebrated their first rendered triangle running with a fully open-source driver stack...

Along with his other pull requests for areas of the kernel he oversees, Greg Kroah-Hartman on Friday submitted all of the staging area changes for the kernel in this "proving grounds" of sorts for the kernel. Thanks to some spring cleaning, the staging area is 13k lines of code less this cycle...

This Sunday, 5 June, marks the 18th birthday for Phoronix.com since I started this website to focus on Linux hardware reviews and performance testing. To mark the occasion, there will be a Phoronix Premium special if you wish to go ad-free on the site and enjoy multi-page articles on a single page while helping to hopefully ensure a successful 19th year for Phoronix...

Following a mad dash this week to get the LoongArch CPU architecture support readied for Linux 5.19, Linus Torvalds successfully merged this MIPS64-inspired Chinese architecture code today into the mainline kernel. However, due to some of the code not yet passing review, while the CPU architecture code is in place some crucial drivers have yet to land and thus Linux 5.19 cannot boot on said hardware...

An open letter started by the Open-Source Firmware Foundation and seeking community support for this letter is calling on Intel to open-source their Firmware Support Package (FSP). The FSP binary blob has been a big limitation to the level of openness around firmware for Intel systems and has been a limiting factor in supporting the likes of Coreboot, LinuxBoot, and other technologies on Intel hardware...

A new patch series posted today by AMD is enabling peer-to-peer support within their AMDKFD kernel compute driver for allowing communication between multiple AMD GPUs over the PCIe bus without needing intermediate copies through system memory. In turn this should help with the multi-GPU compute performance for the Radeon ROCm stack...

A few days ago the RISC-V pull request landed in Linux 5.19 with support for RISC-V 32-bit (RV32) binaries on RV64, enabling the new Svpbmt extension, and other improvements. On Friday a secondary set of RISC-V changes were sent in for Linux 5.19 that includes adding the DeviceTree files for another new RISC-V board...

Greg Kroah-Hartman has gotten onto submitting his feature pull requests to Linux 5.19 for various areas of the kernel he oversees. With the driver core changes with this new kernel is now the ability to compress firmware files using the popular Zstd...

While SiFive has sadly shutdown production on the current HiFive Unmatched development board in order to focus on new products expected later this year, those with a SiFive HiFive Unmatched RISC-V developer board can enjoy seeing continued performance improvements with newer Linux distributions.

Google has been helping small open-source projects get started in chip fabrication with Google covering the costs and partnering with SkyWater Technology using their open-source process design kit (PDK). While the chip manufacturing is done on a 130nm process (SKY130), this effort has proven to be a big success for open-source hardware projects with limited funding and Google today announced a new silicon design portal...

Back in February Intel announced it was acquiring Linutronix as the folks maintaining real-time Linux (PREEMPT_RT) and other prominent Linux contributions. Today Intel announced another exciting software acquisition for bolstering their open ecosystem...

While Ubuntu 22.04 LTS was just released over one month ago, it is shipping on the Linux 5.15 kernel that was already two stable series behind at release time but chosen as the default due to its long-term support status. Ubuntu 22.04 also shipped with Mesa 22.0 as the latest stable version albeit the open-source OpenGL/Vulkan graphics drivers are quick to advance. So if you've been thinking about upgrading Mesa or the Linux kernel on your Ubuntu 22.04 system for better Linux gaming performance, here are some benchmarks looking at such performance impact for AMD RDNA2 / Radeon RX 6000 series graphics.

While the just talked about Nouveau beginning to land GeForce RTX 30 "Ampere" open-source support is exciting, as mentioned there still are hurdles to overcome for having good open-source NVIDIA driver performance on modern GPUs. So equally exciting news is that Nouveau has begun adapting some of their code into a standalone library so it can be used in the future by other new driver(s)...

Early bits of NVIDIA GeForce RTX 30 "Ampere" support were merged today into Mesa 22.2...

Back during the Linux 5.18 merge window in March I wrote about a big NUMA benchmark performance regression I noticed and bisected. It turns out there has been a fix for it in patch form albeit I only noticed this weekend and now was able to successfully test and verify the fix. That fix is now working its way to the mainline kernel...
