As usual, following yesterday's release of Linux 5.0 the GNU/FSF folks have put out their re-base of their version of the Linux kernel that strips out support for drivers depending upon binary-only firmware, the ability to load non-free (closed-source) kernel modules, and other functionality removed that isn't in strict compliance with open-source standards...

Collabora's Tomeu Vizoso has posted an initial set of patches he's been working on along with Rob Herring on developing a new open-source kernel DRM driver for Arm's Bifrost and Midgard graphics hardware...

It's always been a bit odd how the de facto Vulkan SDK is through LunarG rather than The Khronos Group, which could lead to confusion for those not familiar with the great folks at LunarG. But now it will be more clear with LunarG officially donating their Vulkan software development kit to Khronos...

Dirt Rally 2.0 was released last week by Codemasters as the successor to 2015's Dirt Rally and another title on the EGO Engine. While Dirt Rally saw a native Linux port, Dirt Rally 2.0 hasn't seen any port announced by Feral Interactive (though they are currently porting DiRT 4 to Linux), but what's very exciting is this brand new Windows game runs great under Valve's Steam Play with Proton and DXVK! The experience for Dirt Rally 2.0 is quite great on Linux already thanks to Steam Play and with this being a benchmark-friendly game, here are some NVIDIA GeForce and AMD Radeon benchmarks of this racing game on Linux.

With there being a lot of interest from when Intel recently open-sourced their SVT-AV1 video encoder and more recently their VP9 video encoder also under the "Scalable Video Technologies" umbrella, here are benchmarks from 27 different systems showing off their performance. Plus for kicks there are also some other CPU-based video encode benchmarks including AOM-AV1 and others...

Linus Torvalds has gone ahead and just issued the Linux 5.0 stable kernel for what originally began as the Linux 4.21 kernel cycle. The Linux 5.0 kernel cycle delivers on the mainline AMD Radeon FreeSync support, continued work on bringing up Intel Icelake and other new CPU features, Logitech high-resolution scrolling capabilities, network improvements, and much more...

With it being a little over one year since Spectre and Meltdown mitigations became public and with the Linux kernel today hitting the big "5.0" release, I decided to run some benchmarks of the current out-of-the-box performance hit as a result of the current default mitigation techniques employed by the Linux kernel. The default vs. unmitigated performance impact for Spectre/Meltdown are tested on an Intel Core i7 and Core i9 systems while there is also an AMD Ryzen 7 box for reference with its Spectre mitigation impact on Linux 5.0.

ReactOS 0.4.11 is now available as the newest version of this open-source operating system re-implementing the Windows APIs with a focus on binary driver/application compatibility. With this being the first release since November's ReactOS 0.4.10, there are a fair amount of changes to find in this new build...

That AI accelerator focused on speeding up deep learning inference workloads better than CPUs and GPUs will now see this new driver mainlined with Linux 5.1 while a user-space thunk driver has now been published...

While X.Org Server 1.20.4 was just released a few days ago with XWayland improvements and more, for vintage computer enthusiasts there is now the X.Org Server 1.19.7 that was released independently to provide a six for helping out the SiS 6326. Yes, the graphics processor from 1998...

Trinity Desktop R14.0.6 is being prepared as the latest update to this fork of the KDE 3 package set that continues providing bug fixes and maintenance for those still wanting to live on the KDE3 experience in 2019...

As something that arguably should have been done long ago, developers drafting plans for Fedora 31 are planning to introduce single-package gating so packages don't actually land in Rawhide (the Fedora development repository) until they successfully pass their tests... This should help weed out broken packages in Fedora Rawhide and lead to a more usable experience for those living on Fedora's bleeding-edge while also helping along a smooth release process...

GNOME 3.32 already picked up a wealth of improvements, polishing, and fixing this cycle, but as we hit the final stretch ahead of the desktop's release in two weeks a big feature just squeezed in.....

NVIDIA for a while now has been working on the Flang compiler as an open-source Fortran compiler built atop the LLVM infrastructure and inspired by the Clang C/C++ compiler front-end. Recently though they began a ground-up rewrite of Flang using modern C++ and that effort is now known as f18 and they are looking to mainline this new Fortran compiler front-end...

On Monday we published the initial GeForce GTX 1660 Ti Linux benchmarks focused on gaming but due to having only a limited amount of time with that new Turing GPU at the time, CUDA/OpenCL benchmarks were yet to be completed. Our initial GPU compute tests with that "TU116" graphics card is now complete and we have those Ubuntu Linux benchmark results for sharing.

Seeming to affect mostly Apple MacBook laptops, some systems since Linux 4.17 and newer have failed to boot but fortunately a fix is now queued for landing into the mainline tree and being back-ported to the stable branches...

Joshua Ashton, the developer who had been working on "DXUP" as a Direct3D 9/10 to D3D11 translation layer so that the output could be fed to DXVK for running on Vulkan is now developing the "D9VK" project...

While we have looked extensively at the performance of generated binaries of user-space applications built under GCC 9, soon we'll be able to benchmark a complete system image built under this annual compiler update to the GNU compiler as Clear Linux is planning a quick roll-out of the soon-to-be-released compiler...

An effort ongoing for a few years now has been the CONFIG_LOCK_DOWN_KERNEL patches to prevent user-space from being able to modify the kernel image with blocking the ability to load unsigned kernel modules, no writing to /dev/mem, restricting PCI BAR and MSR access, ACPI restrictions, and more. Some Linux distributions are already carrying this work in some form and enabling it with UEFI SecureBoot, but it hasn't been mainlined although could soon change...

That point release is now available...
