Intel mOS, Cachy, Mozilla Layoffs Were The Open-Source Buzz Of August

Written by Michael Larabel in Phoronix on 1 September 2020 at 12:05 AM EDT. Add A Comment
August was an interesting month in terms of Linux/open-source activity though still another tough month during the coronavirus pandemic.

During the month of August on Phoronix were 273 original news articles and just 10 featured Linux hardware reviews/featured articles. The news count is still close to the average of 10 new/original news articles each and every day of the year while the review/featured count is off the usual track of around one per day... That is due principally due to declining ad revenue rates and ad-block users making operations incredibly difficult with everything going on this year (and still striving for 100+ hour work weeks on top of having an infant). In September though will be a new ad partner serving all of the ads on Phoronix so that should bring some uplift. In any case if you would like to enjoy Phoronix ad-free or show your support you can join Phoronix Premium and/or consider a PayPal tip to show your support for Phoronix in its sixteenth year and continuing to see new content each and every day.

As for the most popular news articles on Phoronix over the course of the past month, the most viewed items include:

Mozilla's Incredible Speech-To-Text Engine Is At Risk Following Layoffs
For a while now a Mozilla software project that's been an "unsung hero" has been DeepSpeech as their speech-to-text engine. Sadly, following the recent major layoffs at Mozilla and restructuring along with a shift to focusing more on their profitable activities, DeepSpeech for now has an uncertain future.

Linux 5.9 Brings Safeguard Following NVIDIA's Recent "GPL Condom" Incident
Stemming from the recent discussions over NVIDIA NetGPU code that relied on another shim for interfacing between NVIDIA's proprietary driver and the open-source kernel code, a new patch is on the way for Linux 5.9 to fight back against such efforts.

A "Large Hardware Vendor" Wants A EULA Displayed For Firmware Updates On Linux
The open-source Fwupd firmware updating utility paired with LVFS as the Linux Vendor Firmware Service has seen explosive growth for vastly improving the BIOS/firmware updating experience on Linux. Many major hardware vendors distribute their firmware updates on LVFS for consumption by Fwupd and more than 17 million firmware files have been served. Now though there is a new "large hardware vendor" willing to distribute their firmware updates this way but they want a end-user license agreement (EULA) added.

Kernel Developers Work To Block NVIDIA "GPL Condom" Effort Around New NetGPU Code

This latest work is being driven by code recently put out for improving the Linux networking code where NVIDIA's proprietary kernel driver would be the initial consumer.

Linux Developers Continue Evaluating The Path To Adding Rust Code To The Kernel
As mentioned back in July, upstream Linux developers have been working to figure out a path for adding Rust code to the Linux kernel. That topic is now being further explored at this week's virtual Linux Plumbers Conference and it's still looking like it will happen, it's just a matter of when the initial infrastructure will be in place and how slowly the rollout will be.

Some Ugly Code Can Get NVIDIA's Linux Driver Working With Accelerated XWayland
Red Hat's Adam Jackson has been working on "GLX Delay" as a means of offering accelerated GLX with OpenGL for XWayland when using the NVIDIA proprietary driver. The proposed code is going through Mesa even though it's for the proprietary NVIDIA driver benefit and also requires a change to the OpenGL Vendor Neutral Dispatch Library (libglvnd).

Alibaba Reports Their XT910 RISC-V Core To Be Faster Than An Arm Cortex-A73
A few weeks back Alibaba announced the "XT910" as the fastest RISC-V processor featuring 16 cores and clock speeds up to 2.5GHz while being manufactured on a 12nm node.

Microsoft Is Exploring LTO+PGO For A Faster Linux Kernel
While more and more software vendors are employing link-time optimizations (LTO) and profile-guided optimizations (PGO) for leveraging the compiler to squeeze out performance, it may surprise many that Microsoft engineers are exploring LTO+PGO for the Linux kernel in their own quest of achieving greater Linux performance.

Paragon Looks To Mainline Their NTFS Read-Write Driver To The Mainline Linux Kernel
With the mainline NTFS driver in the Linux kernel offering read-only support for this widely-used Microsoft file-system and the more popular "ntfs-3g" driver being FUSE-based, Paragon Software is looking to mainline their read-write driver into the mainline kernel tree as a significant improvement over the existing NTFS kernel driver. But in the current state it's not clear if the driver will be accepted.
