For the past two decades Red Hat has been behind Sourceware.org for providing hosting for open-source projects like Cygwin, GNU GCC, GDB, Glibc, and many other projects. While Red Hat continues to sponsor the hosting and having their employees be involved with the Sourceware.org maintenance, etc, for ensuring a secured future they have been looking to hookup with the Software Freedom Conservancy (SFC). The SFC has now voted in favor of accepting this long-time open-source hosting service into their umbrella...

With the AMD Ryzen 7 5800X3D as the first consumer processor with AMD 3D V-Cache technology that launched earlier this year, the Linux performance has been fantastic for a variety of workloads especially in areas of technical computing and other non-gaming workloads -- similar to the great results we've enjoyed with AMD EPYC Milan-X processors too. One of the areas I hadn't had a chance to look at until recently was how the Windows 11 vs. Linux performance is looking for this Ryzen CPU with its 96MB L3 cache. Here are those quick benchmarks.

Blender 3.3 is set to be released today and one of the exciting enhancements with this open-source, cross-platform 3D modeling software update is initial support for Intel oneAPI/SYCL GPU acceleration. Intel Arc Graphics discrete GPUs can now enjoy this accelerated Cycles back-end, permitting your driver stack is new enough on Windows or Linux and are using their new dGPUs and not existing integrated graphics. But this is just the start of their oneAPI GPU-accelerated push for Blender...

Since Apple introduced the M1 two years ago as their in-house Apple Silicon for laptops and desktops with a powerful AArch64 processor and custom-designed graphics processor, there has been much speculation about whether the Apple M1 (and now M2) graphics are a clean-sheet Apple design or derived from Imagination PowerVR graphics that Apple had been using with earlier SoCs. There has been some similarities brought up before with the Asahi Linux team working on enabling the Apple M1/M2 under Linux while the latest Mesa driver activity points to more common bits between PowerVR graphics hardware and the Apple AGX graphics...

Overnight some fresh workarounds were merged into Mesa 22.3-devel as the latest Linux driver improvements for Intel's forthcoming discrete graphics cards...

Back in July I called attention to the issue how Linux 5.19 was set to break Alder Lake P graphics support unless moving to new graphics micro-controller "GuC" firmware in tandem. That user-space breakage is frowned upon and following that article the upstream DRM kernel maintainers outlined explicit requirements around firmware not breaking driver support. Intel engineers ended up submitting a quick fix for Linux 5.19 to still support the existing firmware while now a more adequate solution has been devised...

With Fedora 39 next spring it will likely replace DNF, libdnf, and dnf-automatic with the new DNF5 packaging tool and libdnf5 support library. DNF5 should improve the user experience and deliver better performance for dealing with software management on Fedora Linux...

Following the July disclosure of the Retbleed CPU security vulnerability affecting older processors and an AMD change made in August, here is a fresh look at the performance impact of the Retbleed mitigations on Linux, including if opting for the IBPB-based Retbleed mitigation, and the accumulated CPU security mitigation impact for Zen 2 with the flagship Ryzen 9 3950X processor.

Mesa recently landed BPTC software fallback handling that is a requirement for OpenGL 4.2 support but BPTC is not natively supported by all GPU hardware, particularly on the embedded side. That software emulation support for BPTC is similar to what already has existed within Mesa for the ASTC and ETC formats too. A merge request is pending that also adds S3TC software fallback handling, which helps out some of the smaller, embedded GPU drivers too for getting more games running that are dependent on S3 Texture Compression...

Currently when it comes to shipping new/updated device support for firmware updating under Linux with FWUPD/LVFS, it requires making/adjusting a Fwupd plug-in for carrying out the actual firmware copying/updating of the device and then adding in the device VID/PID to a quirks table so Fwupd knows about what to match a given device to for the firmware plug-in to use. Even in new devices where no plug-in changes are required, new device entries are still needed in the quirks table and it makes it challenging when Linux distributions don't quickly move to new FWUPD releases. Moving forward a better solution is being explored...
