You may recall last year how several prominent upstream kernel developers recommended avoiding Intel's latest laptops for Linux use that bear their IPU6 MIPI camera over the lack of upstream open-source support. It's taken some months but the initial IPU6 Linux kernel driver patches are out for review and will hopefully make it to the mainline Linux kernel in the months ahead...

While distributions like Fedora Linux have been using Dbus-Broker for years already as their high performance D-Bus compatible implementation to, for Ubuntu 23.10 later this year is finally where it looks like Ubuntu will be transitioning to this better alternative to dbus-daemon...

A set of patches to the AMDGPU Linux kernel driver and Mesa's RADV Vulkan driver would allow more easily relaying information about the reasons why a GPU hang/reset occur so that the user-space software can be more informed about any issues...

The USB/Thunderbolt changes were merged last week for the Linux 6.4 kernel and it ended up being a net reduction in the number of lines of code as a result of ditching two outdated USB drivers...

As expected following yesterday's AMD Git activity, ROCm 5.5 was officially released overnight as AMD's latest version of their open-source GPU compute stack that is their alternative to NVIDIA's CUDA or Intel's oneAPI / Level Zero...

The Device Mapper "DM" subsystem updates have been merged for the in-development Linux 6.4 kernel and it includes some notable performance optimizations...

Last week System76 released System76-Scheduler 2.0 as their Rust-written Linux desktop scheduler that serves as a user-space daemon to dynamically manage process priorities to favor performance and responsiveness. That's now been succeeded by a v2.0.1 update with a few more features and improvements...

Last year DreamWorks announced they would be open-sourcing their award-winning MoonRay renderer. Back in March that dream was realized with OpenMoonRay being published for this renderer that has been used for films like Puss In Boots: The Last Wish, The Bad Guys, How To Train Your Dragon: The Hidden World, and other films. OpenMoonRay 1.1 is now available as the first update to this professional renderer since it was open-sourced last quarter...

At the start of April there were the Steam Survey results for March 2023 that showed a 0.54% dip to the marketshare. With that were als some strange shifts in the Windows 10 vs. 11 marketshare as well as a big boost to the Chinese marketshare. The March numbers were not revised but with the start of May comes the April numbers... Showing a boost to Linux and largely recovering from the April anomaly...

Last November ClamAV 1.0 was released for this anti-virus/anti-malware solution currently developed via Cisco and the open-source community. Following ClamAV 1.0 LTS, today marks the availability of ClamAV 1.1 as the first post-1.0 feature release...

AMD has begun publishing ROCm 5.5 source packages for the Radeon Open eCosystem components making up their GPU compute stack that is also being extended to cover Xilinx products and more...

Red Hat organized an HDR hackfest to bring together all the Linux desktop stakeholders around the desktop, display drivers, and related infrastructure for helping to make progress on High Dynamic Range (HDR) display support. The event took place last week at Red Hat's Brno office in the Czech Republic and sounds like it was quite a success...

Since last November has been a kernel bug report from a Canonical engineer after finding that the Intel Thunderbolt USB controller on various laptops was "dead" after resuming the system. That problem is now resolved with Linux 6.4 and this generic fix may end up helping other hardware as well...

While there is already Fedora Silverblue as a Fedora Workstation variant leveraging RPM-OSTree for creating an ummutable OS image and Fedora Kinoite as a KDE-based alternative, Fedora Onyx has been proposed as a new immutable variant of Fedora Linux...

With Linux running on everything from tiny single board computers with basic WiFi or Ethernet networking up through massive super-computer clusters, the Linux networking subsystem continues seeing immense improvements each kernel cycle. With Linux 6.4 the networking changes are heavy from new hardware support (including Apple M1 Pro/Max WiFi!) to continued work around WiFi 7 support as well as never-ending work on performance optimizations...

Intel's open-source "cartwheel-ffmpeg" project is their repository where they collect all of their FFmpeg patches prior to upstreaming. While the patches have been available in Git form, prior to the weekend Intel released their 2023Q1 queue of patches to this widely-used, open-source multimedia library...

Near the start of 2022 engineers out of the Qualcomm Innovation Center posted Linux driver patches for their Gunyah hypervisor. Gunyah is an open-source type-1 hypervisor developed by Qualcomm with an emphasis on security and other features. More than one year later the Gunyah drivers have yet to be upstreamed into the mainline Linux kernel but work on them persists...

Merged last week for the Linux 6.4 kernel were all of the VirtIO and Virtual Data Path Acceleration (VDPAU) changes. Interesting from that pull request is delivering a big performance bump for VDUSE...

In recent years Linus Torvalds hasn't had the time to write too much original new code for the Linux kernel himself with these days mostly managing developers, providing insightful mailing list posts, and reviewing code for merging into the kernel tree along with related tasks. For Linux 6.4 though he did manage to write up some new code...

During this month on Phoronix were 242 news articles on Phoronix with original content each and every day presented by your's truly around open-source and Linux. April was interesting with the release of Linux 6.3, all of the exciting Linux 6.4 features merged so far, AMD introducing openSIL for open-source CPU silicon initialization with support for Coreboot and similar firmware solutions, Fedora 38 and Ubuntu 23.04 being released, and much more...
