LLVM's Flang/F18 Fortran Compiler Might Be Back On Track For Merging Soon

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.

Canonical Contributing Upstream Improvements To Plymouth Ahead Of Ubuntu 20.04 LTS

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.

C-SKY Architecture Gets Fix For Its Own Speculative Execution Bug In 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.

Looking At The LVI Mitigation Impact On Intel Cascade Lake Refresh

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.

Open-Source Unvanquished Game Aiming For A New Release Soon

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.

The New Microsoft exFAT File-System Driver Has Landed In Linux 5.7

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.

Dell XPS Ice Lake Taking A Wallop On Ubuntu 20.04

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.

Ada++ Wants To Make The Ada Programming Language More Accessible

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.

LLVM Lands Performance-Hitting Mitigation For Intel LVI Vulnerability

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.
