LOOPFS is the latest Linux kernel file-system proposal.

Patches have been revised for allowing Linux to support kernel stack base address offset randomization for each system call.

With an apparent blame on the novel coronavirus, The Qt Company is said to be considering restricting new Qt releases to paying customers for a period of twelve months in an effort to boost their near-term finances.

Last week there were a bunch of new improvements and features for the open-source kernel graphics/display drivers merged for Linux 5.7. There were not any feature changes on the open-source NVIDIA "Nouveau" driver front while this week at least are some fixes/workarounds so it's less buggy for some hardware.

The OverlayFS union mount file-system has a number of fixes and other changes with Linux 5.7.

The Qt Company has made public their 2020 road-map for Qt software releases.

The TURNIP open-source Vulkan driver continues advancing in-step with the other Mesa drivers.

At the end of last year with ROCm 3.0 AMD introduced the AOMP compiler for OpenMP support targeting Radeon GPUs. AOMP is another downstream of LLVM Clang and on Tuesday marked the latest update.

We have begun seeing the start of upstreaming on Google's Propeller Framework for offering post-link-time binary optimizations in the LLVM compiler stack to offer measurably faster (re)generated binaries.

The GNOME Foundation in cooperation with Endless has launched their first Community Engagement Challenge where they are offering up many prizes and cash.

While Intel's open-source Linux hardware support is extremely good even in time for launch day of not only for their server / data center products but also desktop and mobile platforms, occasionally there are exceptions. One of the biggest exceptions over the past decade has been the Bay Trail support sometimes taking years to see fixes or finishing up areas of the support. The latest example of this is some Intel Bay Trail and Cherry Trail tablets finally seeing working/reliable touchscreen support on Linux 5.7.

Less than one month ago came the big Vulkan 1.2.135 update with official ray-tracing capabilities and other extension promotions. Out today is Vulkan 1.2.137 with a whole lot of clarifications and fixes.

NVIDIA today released the 440.82 Linux binary display driver as their newest stable update in the current 440 driver series.

Mozilla has released Firefox 75.0 as what is a big update for Linux users.

The AMD "ACO" compiler backed by Valve for offering a faster shader compiler back-end than AMDGPU LLVM for the RADV open-source Radeon Vulkan driver has begun making use of Navi's NGG "Next-Gen Geometry" hardware.

One of several GNU projects that have been silent in recent years is MediaGoblin, the effort to provide a free and decentralized web platform for sharing of digital media.

The Flash-Friendly File-System (F2FS) updates have been sent in for the very active Linux 5.7 kernel.

Since the "f18" open-source Fortran compiler front-end was approved last year for merging as the newest LLVM sub-project and using the Flang name, there have been a number of false starts in getting the code merged. This year alone Flang had multiple delays and cancelled merge plans as the developers worked to get the code ready for upstream. Now though it looks like it could be ready to cross that long sought after milestone for having an in-tree Fortran front-end.

One of the immediate differences Ubuntu 20.04 desktop/laptop users will notice when booting in UEFI mode is the boot splash screen improvements thanks to leveraging Red Hat's work on providing a flicker-free boot experience and pulling in the UEFI BGRT system/motherboard logo during the boot process to provide a more transitive experience. Canonical in turn is working on pushing some of their improvements back into upstream Plymouth.

On top of all the other changes in Linux 5.7 so far, a secondary set of power management updates were sent in today for this next version of the kernel and includes now using the Schedutil governor by default for Intel P-State and Arm big.LITTLE systems.

One month ago to the day I was writing about OpenGL threading improvements for Mesa 20.1 and since then more "GLTHREAD" work has materialized and successfully landed for improving the Mesa OpenGL driver performance.

We are now one week through the two week long Linux 5.7 kernel merge window where new/improved functionality is introduced. Here is a look at the changes so far for Linux 5.7.

C-SKY is a Chinese 32-bit CPU architecture intended for low-power devices from media boxes / DVRs to printers and other consumer electronics. C-SKY has also worked its way into a ~$6 development board. With its updates for the Linux 5.7 kernel are various additions to this maturing architecture support along with a speculative execution fix.

A new patch series sent out just under one month ago was providing opt-in L1 data cache flushing on context switching. That work has now been revived again and now with documentation added it's clear that this work is being done in response to a recent CVE being made public.

Ongoing work around Linux's exec() code should make it less deadlock prone in future kernel versions.

The Linux 5.7 kernel will bring random performance improvements as in /dev/random.

Kaidan is the open-source project that last year joined KDE as a Jabber/XMPP chat client. After a half year of work, Kaidan 0.5 has finally been released.

The perf subsystem continues to be quite lively with improvements and for Linux 5.7 is seeing a number of low-level improvements.

The second development release of the Phoronix Test Suite 9.6 cross-platform benchmarking software is now available for evaluation and testing.

Both of IBM's s390 and POWER CPU architectures are seeing secure/protected guest virtual machine support with KVM on the in-development Linux 5.7 kernel.

While XFS dates back to the 90's and has been in the Linux kernel for nearly two decades, this proven file-system continues aging gracefully and continuing to see more improvements. With Linux 5.7 is another step forward for XFS.

KDE developers managed to squeeze some long-problematic I/O optimizations into the KDE code-base this week along with other enhancements to make for a nice first week of April.

The work led by VMware on allowing the Direct Rendering Manager's TTM memory management code support huge page tables has been added to Linux 5.7.

An important infrastructure change with the Linux 5.7 kernel now allows the ability to create a process in a different cgroup from the parent process.

The MIPS architecture improvements for Linux 5.7 are headlined by Loongson support improvements for those Chinese manufactured MIPS64 platforms.

One of the most promising open-source game projects of the 2010s when it comes to gameplay and visual quality is the Unvanquished project but sadly in recent years has been fairly quiet although new code continues to be contributed to their repository. It looks like in the weeks ahead could finally be a new release.

As we have been expecting the new Samsung-developed file-system driver for Microsoft's exFAT has successfully landed into the Linux 5.7 kernel to replace the existing exFAT driver added in Linux 5.4 last year after Microsoft published the file-system specifications and gave their blessing to have the support mainlined in the Linux kernel.

Some exciting ARM SoCs and devices are supported by the mainline Linux 5.7 kernel.

With our early benchmarking of Ubuntu 20.04 in its current nearing the end of development state, we've been seeing Ubuntu 20.04 boosting Intel Xeon Scalable performance, running well with AMD EPYC Rome, and good AMD Ryzen performance, among other tests. Strangely though the one platform where I've found Ubuntu 20.04 hard regressing so far is with the Dell XPS 7390 Ice Lake.

This week marked the release of ROCm 3.3 as the newest version of the Radeon Open Compute stack.

Added over a year ago to the mainline Linux kernel was the high resolution mouse wheel scrolling support. While the support landed on kernel-side for to provide "buttery smooth" wheel scrolling, the work has yet to be wrapped up on the user-space side for making this a reality on the Linux desktop.

It's been another busy week for Mesa's RADV Vulkan driver with the Valve-backed ACO compiler back-end alternative to AMDGPU LLVM.

With Steam and other online gaming platforms seeing record usage in recent weeks as a result of home isolation around the world as a result of the coronavirus, one of the matters of curiosity has been how this will impact the Linux gaming percentage.

Greg Kroah-Hartman on Friday sent in his "char/misc" updates for the Linux 5.7 kernel several days later than normal.
