GNU C Library 2.31 (Glibc 2.31) should be releasing in the days ahead and is now under a hard freeze for this next feature release to this important libc implementation...
When carrying out our Windows vs. Linux benchmarks we normally are doing so on interesting high-end hardware but for today's benchmarking is a look at how a $199 USD laptop powered by an AMD Ryzen 3 3200U processor compares between Windows 10 as it's shipped on the laptop against the forthcoming Ubuntu 20.04 LTS Linux distribution.
Earlier this month when Intel disclosed CVE-2019-14615 as a security vulnerability affecting their graphics architecture, older Gen7 graphics saw a huge hit to their performance with the initial patches for addressing this vulnerability on Ivy Bridge and Haswell processors. Fortunately, a new mitigation patch series was sent out this week where they believe the performance costs are now avoided...
In addition to Linux Mint 20 coming this year that will be based off Ubuntu 20.04 LTS, the Linux Mint crew is preparing LMDE 4 as their re-base of the Debian based variant...
With the V3D Gallium3D driver hitting OpenGL ES 3.1 compliance, the Raspberry Pi Foundation and their partners have turned to focusing on getting their Vulkan driver off the ground for Raspberry Pi 4 and future SBCs...
Following the Xen hypervisor in mitigating against a possible Spectre Variant One and L1 Terminal Fault combination attack, the Kernel-based Virtual Machine (KVM) has added its own protections with the Linux 5.6 kernel on top of all the other mitigations they've had to endure as a result of CPU vulnerabilities over the past two years...
We previously covered how CERN has moved away from Microsoft products over licensing fees and instead has begun employing various open-source alternatives. Now this European Organization for Nuclear Research is moving away from Facebook Workplace to instead make use of more open-source software packages...
The F2FS file-system compression functionality is the main feature addition for this flash-optimized file-system coming with the Linux 5.6 kernel. This native LZO/LZ4 compression support is geared for optimizing the lifespan of SSDs/flash memory thanks to reducing disk writes...
While not as exciting as the USB4 support and staging code lightening for these areas managed by Linux's second in command Greg Kroah-Hartman, he also sent out the char/misc updates this week with other hardware support improvements...
We've seen a lot of odd products pick up the Free Software Foundation's "Respect Your Freedom" endorsement like a USB microphone, various re-branded motherboards, and even last year certified a USB to parallel printer cable. The latest product they are endorsing -- and their first endorsement of 2020 -- is a USD 802.11 a/b/g/n PCIe half-mini card starting out at $59 USD but going up to $79 for this outdated wireless adapter...
Among many other Valve ACO back-end improvements for Mesa 20.0, one of the notable additions is this AMDGPU LLVM alternative now working for Radeon "Southern Islands" / GCN 1.0 graphics cards. With this, these original AMD GCN graphics cards may have some extra life out of Linux gaming boxes thanks to slightly higher performance some eight years after these graphics cards first launched in the Radeon HD 7000 series.
While WireGuard was merged into Linux 5.6, the Ubuntu 20.04 LTS release is currently tracking Linux 5.4 and for the April release is likely to be shipping with Linux 5.5 as the 5.6 release will be cutting it too close. But Ubuntu 20.04's kernel has now back-ported WireGuard...
In addition to the new openat2() system call in Linux 5.6, pidfd_getfd() has landed with growing interest from many different parties for what will be an increasingly used syscall moving forward...
Earlier this month AMD finally published their Sensor Fusion Hub driver for Linux to improve the Ryzen laptop support. That new "SFH" driver hasn't been queued as part of any Linux 5.6 pull request but a second version of the driver did make it out this week...
With Linux 5.6 the staging area has seen new functionality but thanks to removing old code it ends up removing a fair number of lines of code from the kernel...
The folks at iXsystems have released FreeNAS 11.3, their latest big update to this FreeBSD-based operating system designed around the OpenZFS file-system for offering advanced network-attached storage capabilities...
On top of all the spectacular work coming with Linux 5.6, here is another big improvement that went under my radar until today: Linux 5.6 is slated to be the first mainline kernel ready for 32-bit systems to run past the Year 2038!..
With LLVM Clang 10 having added a Zen 2 scheduler model tuned for the latest AMD CPUs over the existing "znver2" tuning that had just copied the Zen 1 scheduler, here are some benchmarks looking at the LLVM Clang 9 vs. 10 compiler performance on AMD EPYC when making use of "-march=znver2" optimizations...
Since the stable release of Linux 5.5 this weekend I have been carrying out benchmarks for looking at how the performance of this newly-minted kernel compares to older releases. Here are benchmark results of Linux 5.3 vs. 5.4 vs. 5.5 with an AMD Ryzen Threadripper 3970X but the results are similar to other HEDT and lower-end systems we've tested thus far...
A new system call added to the very feature rich Linux 5.6 kernel is openat2() for more extensible behavior compared to the existing openat() functionality...
The Wine project's VKD3D initiative for translating Direct3D 12 support to Vulkan took another step forward today with patches for handling DXIL (Shader Model 6.0+) shaders with VKD3D, but the work in the current form may need to be re-worked...
With Mesa 20.0 scheduled for branching today (though that could be delayed a few days potentially depending upon last minute requests), there's been a flurry of Radeon Vulkan "RADV" driver activity to squeeze into this first Mesa release series of 2020...
Red Hat's Matthias Clasen has provided an update on one of the latest areas the GTK developers are working on finishing up with the forthcoming GTK 4.0 tool-kit... Improving the data transfer interfaces around handling for copy/paste and drag-and-drop...
While developers are hard at work on Godot 4.0 with Vulkan support, that release won't be ready until mid-2020 so as a result Godot 3.2 is out today as their latest stable release and serving as a "long-term support" release until transitioning to Godot 4...
Intel's Andy Shevchenko sent in the x86 platform driver updates on Monday for the newly opened Linux 5.6 merge window. There is the never-ending work on dealing with quirky Windows-focused laptops to adding new Intel hardware support and other additions...
With LLVM Clang 9.0 and Linux 5.3 together it became possible to build the mainline Linux kernel with this non-GCC compiler. The x86_64 Linux kernel Clang-based kernel builds has continued to improve through newer kernel releases. This follows the mainline AArch64 (64-bit ARM) Linux kernel mainline build by Clang too, which has been of much interest by different hardware/software vendors. There hasn't been much Clang'ing kernel efforts for other architectures, but it turns out with Clang 10 and Linux 5.6 will be another working combination, this time for IBM s390...
The Time Namespace, which was originally proposed back in 2018 for allowing per-namespace offsets to the system clocks, has finally entered the mainline kernel in early 2020 with the in-development Linux 5.6 kernel...
Mozilla's Thunderbird mail client has been rather neglected the past several years with all the focus on the Firefox web browser, but as the next step forward for this mail/RSS client is now placing it under the newly-formed MZLA Technologies Corporation...
It turns out Sony is now maintaining the mainline Linux kernel's hid-sony input driver in an "official capacity now across various devices." This hid-sony driver is what traditionally has supported the various PlayStation controllers and other input devices for their hardware. But their newfound "official" support for this open-source input driver could lead to interesting predicaments...
One of the work items we have been keen to monitor during the Ubuntu 20.04 LTS development cycle is tracking the happenings around Zsys, the Ubuntu/Canonical led utility for helping to administer ZFS On Linux systems. In ending out January, Zsys now has more functionality in tow...
While Mesa 20.0 will be entering its feature freeze this week and branching ahead of the stable release expected in about one month, for now the Mesa 19.3 series is the newest available for stable users...
