Six years after AMD introduced "Piledriver" as the successor to the original Bulldozer CPUs, the LLVM Clang compiler is seeing a revised scheduling model for these processors that can yield faster performance of generated code targeting this older class of AMD CPUs.
The AMDGPU DRM Linux kernel driver has offered GPU reset recovery for a while now in case of hangs that can be toggled by a module parameter, but the default behavior for the next kernel release is slated to change where it will be enabled by default for the newer Radeon GPUs.
With the Freedreno Gallium3D driver's reverse-engineered, open-source 3D/OpenGL driver support for Qualcomm Adreno hardware in pretty darn good shape these days even for the latest-generation Adreno 600 series, the developers have begun working on more optimizations -- including a new effort trying to reduce the OpenGL driver's overhead.

Now that WebRender has reached beta within Firefox Nightly, I decided to run some fresh web-browser benchmarks to see how this GPU-accelerated web rendering is working out for Firefox and how it compares to that of Google Chrome in some popular browser benchmarks.
When Linus Torvalds announced last month that he would be taking a temporary leave of absence to work on his empathy and interpersonal skills as well as the adoption of a Linux kernel Code of Conduct, some Internet commenters thought this would lead Linus to being less strict about code quality and his standards for accepting new code to the mainline tree. Fortunately, he's shown already for the new Linux 4.20~5.0 cycle he isn't relaxing his standards but is communicating better when it comes to bringing up coding issues.
Reported at the start of the month were plans for FreeBSD 12 to deprecate many of their 10/100 Ethernet drivers with just leaving the popular fast Ethernet drivers and focusing on Gigabit and beyond networking drivers moving forward.

While System76 is officially announcing their Thelio systems next week on 1 November with plans to then begin shipping these "open hardware" systems in December, today the Linux-friendly PC vendor shared with us some more exclusive details on the forthcoming hardware being manufactured in Denver, Colorado. Here are those exciting details -- much more than just some digital web saga.
This week marked the release of Radeon Software 18.40 as the latest release of AMD's Linux driver stack targeting workstation users. While the sole mentioned change was the addition of SUSE Linux Enterprise 15 support, I decided to run some benchmarks of this latest driver compared to the other open-source Radeon Linux driver options.

Following last week's release of the Intel Core i9 9900K, I spent several days testing various Linux distributions on this latest Core i9 CPU paired with the new ASUS Z390-A PRIME motherboard. I was testing not only to see that all of the Linux distributions were playing fine with this latest and greatest desktop hardware but also how the performance was looking. Benchmarked this round on the i9-9900K was Ubuntu 18.04.1 LTS, Ubuntu 18.10, Clear Linux 25720, Debian Buster Testing, Manjaro 18.0-RC3, Fedora Workstation 29, openSUSE Tumbleweed, and CentOS 7.
After it was delayed last week, the beautiful Fedora 29 will greet the world next week.

With just one week of feature development remaining for the in-development Mesa 18.3, the race is on for landing the remaining feature work ahead of this next quarterly Mesa3D stable version.
The Qt Project has been the latest open-source community constructing a Code of Conduct. The motivation for this CoC in the Qt camp has been driven to "establish a formal line-in-the-sand about what is unacceptable behavior. We want new members of the Qt community to feel comfortable and accepted, and we want to foster a healthy working environment for both current and new members."
Overnight the networking subsystem changes were merged into the mainline kernel for the Linux 4.20~5.0. Sadly not part of this pull request is the much sought after WireGuard secure VPN tunnel but it does bring one of the other features we've been monitoring: the new Intel 2.5G Ethernet driver.
The EFI support code within the mainline Linux kernel continues to be improved upon. While EFI firmware has matured in the past few years to become more reliable, there still are systems/motherboards shipping with various bugs. One of the additions for this next kernel release will better handle rare cases where buggy firmware could hang the kernel.
