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...

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...

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...

Last week Intel released an initial set of micro-benchmarks for their oneAPI Level Zero and with L0 support being plumbed into their open-source Intel Compute Runtime, this weekend I started toying around with some Level Zero benchmarks on a variety of Intel processors.

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...

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...

On Friday I posted some initial numbers looking at the LVI mitigation impact when using the LLVM Clang compiler with that open-source, multi-platform compiler having landed its mitigation this week for Intel's Load Value Injection (LVI) vulnerability that was disclosed in March. Through the weekend I have been running some additional tests of this compiler-based mitigation and in this article are some numbers off Cascade Lake Refresh, which while recently released is reported by Intel to still be vulnerable to this new disclosure.

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...

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...

Ada is a beautiful programming language when it comes to code safety with it continuing to be used by aircraft and other safety critical systems. There is now Ada++ as an unofficial fork of the language focused on making the language more accessible and friendlier in an era of the likes of Rust and Golang attracting much interest...

The PCI subsystem changes were sent out today for the ongoing Linux 5.7 kernel merge window...

Made public in March was the Load Value Injection (LVI) attack affecting Intel CPUs with SGX capabilities. LVI combines Spectre-style code gadgets with Meltdown-type illegal data flows to bypass existing defenses and allow injecting data into a victim's transient execution. While mitigations on the GNU side quickly landed, the LLVM compiler mitigations were just merged today.

For those with extra time on their hands due to being at home and social distancing, Canonical released the Ubuntu 20.04 LTS beta today for testing...

Last month I noted a new Linux driver for a buggy and funky looking mouse. A special driver was created by a community developer due to not all the mice button working otherwise due to not abiding by HID specifications. Now that the driver was merged for Linux 5.7, Linus Torvalds had words to share on this open-source driver...
