Given the impending release of Linux 5.9, I was having some fun with cloc today looking at the current lines of code count for this near-final Linux 5.9 kernel state.
Pitivi 2020.09 is now available (well, actually, was tagged ten days ago but only announced today) as the first release for this GNOME video editor solution since Pitivi 0.999 back in August 2018.
The Linux 5.9 kernel is expected for release this evening which will in turn kick off the Linux 5.10 merge window for the next two weeks. As we've already been closely monitoring the various "-next" development trees in recent weeks of material building up for this next cycle, here is a look at a portion of what's to come for this late 2020 kernel.
While the Linux 5.9 kernel isn't even being released until later today, the ARM64 architectural changes have already been mailed in ahead of the opening of the Linux 5.10 merge window.
Intel engineers continue working on "Protection Keys for Supervisor" support for the Linux kernel as a feature coming to a future generation of processors (presumably Sapphire Rapids). The initial users of this PKS support will be helping to protect persistent memory as well as adding safeguards to Trusted Keys within the Linux kernel.
Seeing new AMDGPU targets added to mainline LLVM for aging Radeon GFX7/GFX8 graphics hardware wasn't what I expected to see this weekend.

KDE developers have been busy not only putting the finishing touches on the soon to be released Plasma 5.20 but also early feature work continues on what will be Plasma 5.21.
It was in January that AMD finally published an open-source Linux driver for their Sensor Fusion Hub used by AMD Ryzen laptops for various sensor functionality. As we approach the end of the year this driver still hasn't been mainlined yet but a new revision was sent out on Friday.

Intel's next Compute Runtime release is going to be exciting as OpenCL 3.0 will be enabled for all graphics hardware found going back to Broadwell CPUs.
Just a friendly reminder and last call that if you wanted to partake in this week's 2020 "Oktoberfest" Phoronix Premium special, it is ending this weekend.
Wine 5.19 is out as the latest bi-weekly development release of this software for running Windows games/applications on Linux and other platforms.
After being in development for more than one year, it looks like with Linux 5.10 there will be EXT4 fast commit support.
Of the many new features in Linux 5.9 with its debut set for this weekend, one of the performance-related changes is Intel FSGSBASE support finally being mainlined. A half-decade after the Linux patches first appeared for this feature present in Intel CPUs going back to Ivy Bridge, the mainline kernel is now patched for this feature that can help out I/O and other context switching heavy workloads. Given many of the same workloads were negatively impacted by the CPU security mitigations of recent years, here is a look at the current mitigated vs. unmitigated performance difference on the Linux 5.9 kernel with an Intel Core i9 9900K CPU for reference on how the mitigation impact is on recent versions of the Linux kernel.
Back in August was the big surprise of file-system driver vendor Paragon Software wanting to mainline their NTFS driver into the Linux kernel that is much more advanced than the existing NTFS Linux driver. While not merged yet, on Friday the latest version was sent out for review.
Not only is the Plasma 5.20 desktop shining and more Wayland improvements and other enhancements queuing for Plasma 5.21, but the Plasma Mobile effort is also beginning to shine.
Expected with next year's Intel Sapphire Rapids Xeon CPUs is the Intel DSA as the Data Streaming Accelerator for high performance data movement and transformation operations. Since the end of 2019 there have been Linux patches surfacing for bringing up the DSA support and now as we roll into 2021 the Linux kernel looks to begin making use of the new capabilities.
New to the RTX 30 series and the NVIDIA 455 Linux driver is decode support with VDPAU for VP9 10-bit and 12-bit content, which can now be taken advantage of by the popular FFmpeg multimedia library.
While AMD is providing great pressure against Intel in the CPU space, it looks like AMD could be soon going up against them in the FPGA space too.
The PowerPC 601 as the first-generation processor supporting the 32-bit PowerPC RISC instruction set in the early 90's is being retired with the upcoming Linux 5.10 kernel.
Some HP Spectre laptops and possibly other HP models as well should be performing better when running on AC power starting with the Linux 5.10 kernel.
It's finally Zen 3 launch day! It's a virtual event given the ongoing pandemic, but this much anticipated CPU launch is now streaming.
Today perhaps will be the most interesting day since the start of the pandemic... It's finally the day where AMD Zen 3 desktop CPUs are expected to be revealed in just about one hour's time! Stay tuned, but before that virtual event, here is a word on the Linux prospects and support for these upcoming AMD CPUs.
Following last month's release of GNOME 3.38, out today is GNOME 3.38.1 as the first point release to this H2'2020 Linux desktop environment.
With this quarter's Mesa 20.3 the Gallium3D "Clover" state tracker providing OpenCL support finally can handle version 1.2!
Tencent developers have proposed "DMEMFS" as a virtual file-system with the intent of helping to save system memory on large servers such as in public cloud environments.
It looks like for Linux 5.11 there could be lower power usage during video playback on DCN 2.1 hardware, namely AMD Renoir.
Launched at the start of the year was the Kubuntu Focus as a polished KDE laptop while now it's been succeeded by a second-generation model.
Patches from a Google engineer allow run-time average power limiting (RAPL) support for AMD Zen processors within the Linux PowerCap driver.

At the end of September there were Mesa patches posted for the "Dimgrey Cavefish" at the same time as also posting VanGogh APU support for the RadeonSI Gallium3D driver. The AMDGPU Linux kernel driver support has now been posted for the Dimgrey Cavefish.
DXVK 1.7.2 was just released as this popular library for mapping Direct3D 9/10/11 atop the Vulkan API primarily for accelerating Windows games on Linux via the likes of Steam Play (Proton) and Wine.
