Samsung Open-Source Group Reportedly Shuts Down

If you are looking for new open-source talent for your organization, check out LinkedIn but it's under unfortunate circumstances for the availability of a sudden surplus in skilled Linux/FLOSS developers... Samsung has apparently shut down the Samsung Open-Source Group (Samsung OSG) as a blow to the wider free software ecosystem considering the group's prolific contributions over the years from low-level open-source projects to desktop/user-facing code-bases.

Linus Torvalds Shows His New Polite Side While Pointing Out Bad Kernel Code

When Linus Torvalds announced last month that he would be taking a temporary leave of absence to work on his empathy and interpersonal skills as well as the adoption of a Linux kernel Code of Conduct, some Internet commenters thought this would lead Linus to being less strict about code quality and his standards for accepting new code to the mainline tree. Fortunately, he's shown already for the new Linux 4.20~5.0 cycle he isn't relaxing his standards but is communicating better when it comes to bringing up coding issues.

Radeon Software 18.40 vs. Mesa vs. AMDVLK Benchmarks With Radeon RX Vega

This week marked the release of Radeon Software 18.40 as the latest release of AMD's Linux driver stack targeting workstation users. While the sole mentioned change was the addition of SUSE Linux Enterprise 15 support, I decided to run some benchmarks of this latest driver compared to the other open-source Radeon Linux driver options.

QEMU Making Progress With Legacy-Free Display Support - Avoids Old VGA Code

As part of QEMU's emulated display support they have long had a lot of old VGA/SVGA support code around. But as that code is overly complex, has been prone to security issues, and less used these days with modern interfaces, the developers behind this important piece of the open-source virtualization stack have been working on eliminating the legacy display support.

XFS & EXT4 Offer Up Modest Changes For Linux 4.20~5.0

The changes are not as notable as Btrfs having multiple performance improvements or multiple new features for F2FS, but the XFS and EXT4 mature file-systems have their latest advancements now queued for the next kernel cycle.

8-Way Linux Distribution Benchmarks On The Intel Core i9 9900K - One Distro Wins 67% Of The Time

Following last week's release of the Intel Core i9 9900K, I spent several days testing various Linux distributions on this latest Core i9 CPU paired with the new ASUS Z390-A PRIME motherboard. I was testing not only to see that all of the Linux distributions were playing fine with this latest and greatest desktop hardware but also how the performance was looking. Benchmarked this round on the i9-9900K was Ubuntu 18.04.1 LTS, Ubuntu 18.10, Clear Linux 25720, Debian Buster Testing, Manjaro 18.0-RC3, Fedora Workstation 29, openSUSE Tumbleweed, and CentOS 7.

X.Org Server 1.20.3 Released To Fix New Security Issue

We've known that the X.Org Server security has been a "disaster" (according to security researchers) and while many bugs have been fixed in recent years, not all of the security bugs date back so far in the decades old code-base. Out today is X.Org Server 1.20.3 to fix a new CVE issued for X.Org Server 1.19 and newer.

STACKLEAK Plug-In Being Reattempted For Inclusion In Linux 4.20

Originally attempted for the Linux 4.19 kernel but not merged that cycle was the STACKLEAK GCC plug-in that was ported for the mainline code-base from the Linux GrSecurity patch-set. That plug-in is now trying to get into the Linux 4.20 (or perhaps relabeled as 5.0) kernel.

GNU Linux-libre 4.19-gnu Released, Continues Deblobbing The Kernel

Building off Monday's release of Linux 4.19 is now the downstream GNU Linux-libre 4.19-gnu kernel that strips away code contingent upon closed-source microcode/firmware images as well as removing the ability to load closed-source kernel modules.

PCI Peer-To-Peer Support Merged For Linux 4.20~5.0

The recently covered PCI peer-to-peer memory support for the Linux kernel has indeed landed for the 4.20~5.0 kernel cycle. This is about PCI Express devices supporting peer-to-peer DMA that can bypass the system memory and processor via a standardized interface.

AMD EPYC Sees Some Performance Improvements With Linux 4.19

I am still finishing up work on my Linux 4.19 kernel stable benchmarks given it's been (and continues to be) a very busy month for Linux hardware testing, but of interest so far has been seeing a few EPYC performance improvements in some of the real-world workloads.

Qt Drafts A Code of Conduct To Have A Formal Line About Unacceptable Behavior

The Qt Project has been the latest open-source community constructing a Code of Conduct. The motivation for this CoC in the Qt camp has been driven to "establish a formal line-in-the-sand about what is unacceptable behavior. We want new members of the Qt community to feel comfortable and accepted, and we want to foster a healthy working environment for both current and new members."

The Next Linux Kernel Will Further Fend Off Buggy EFI Firmware

The EFI support code within the mainline Linux kernel continues to be improved upon. While EFI firmware has matured in the past few years to become more reliable, there still are systems/motherboards shipping with various bugs. One of the additions for this next kernel release will better handle rare cases where buggy firmware could hang the kernel.

XArray Tries Once Again To Get Merged Into The Mainline Linux Kernel

Going back several release cycles has been an effort to add the XArray data structure to the Linux kernel but to date that hasn't happened. It wasn't accepted for Linux 4.19 and now Matthew Wilcox -- who began this work about two years ago as a programmer at Microsoft -- is hoping Linux 4.20~5.0 will be the lucky release.

The Linux Kernel's Speck Death Sentence Finally Being Carried Out

Earlier this year the Speck encryption algorithm was added to the Linux kernel as at the time Google intended to use it for EXT4/fscrypt file-system encryption with low-end Android devices. But Speck with all its controversy due to being developed by the US National Security Agency (NSA) led to immediate backlash. The removal of Speck from the Linux kernel tree is finally happening.

A 2018 Autumn Linux Driver Update For The ATI RAGE 128 Series

The open-source display driver for supporting these graphics cards where 32MB of SDRAM was suitable, 250 nm fabrication was standard, and core clocks around 100MHz were competitive is still being maintained... Two decades after the release of the ATI RAGE series, the open-source Linux driver continues seeing some activity and in fact a new driver release.
