One of several projects implementing the OpenGL graphics API over Vulkan has been Think Silicon's GLOVE library. GLOVE currently is focuses on OpenGL ES 2.0 + EGL 1.4 support and is a standalone project unlike Mesa's Zink Gallium3D driver working on OpenGL / GLES over Vulkan too. GLOVE 0.4 is out today as a big feature update...

Last week I eagerly reported on Ryzen CPUs on Linux finally seeing CCD temperatures and current/voltage reporting thanks to new patches to the k10temp driver by Google's Guenter Roeck who oversees the kernel's hardware monitoring "HWMON" subsystem. The patches seem to be working well and are tentatively queued in hwmon-next, but more testing is still needed...

While there has been the initial Microsoft exFAT file-system driver since Linux 5.4, that code is based on a vintage snapshot of prior Samsung code. Samsung engineers meanwhile have been working to upstream a much newer and better off exFAT implementation to replace that existing driver and it looks like it could be ready for Linux 5.6...

Following the recent AppArmor performance regression in Linux 5.5 (since resolved), some Phoronix readers had requested tests out of curiosity in looking at the performance impact of Fedora's decision to utilize SELinux by default. Here is how the Fedora Workstation 31 performance compares out-of-the-box with SELinux to disabling it.

A few days ago I reported on AMD's "k10temp" Linux kernel driver finally seeing the ability to report CCD temperatures and CPU current/voltage readings as a big improvement to this hardware monitoring driver. The work hasn't yet been queued for inclusion into the mainline kernel, but initial testing is working well and a second revision to the patches has been sent out...

Red Hat engineers have been developing virtual data path acceleration (vDPA) as a standard data plane that is more flexible than VirtIO full hardware offloading. The goal is providing wire-speed Ethernet interfaces to virtual machines in an open manner...

For a decade now snapshot.debian.org has been around for accessing old Debian packages and to find packages by dates and version numbers. Only now though is a guide materializing for leveraging this Debian "wayback machine" in order to help in bisecting regressions for the distribution that span multiple/unknown packages...

On Wednesday I shined the light on the initial performance hit from Intel's CVE-2019-14615 graphics vulnerability particularly striking their "Gen7" graphics hard. That initial testing was done with Core i7 hardware while here are results looking at the equally disturbing performance hits from Core i3 and i5 affected processors too...

Nearly four years since forking from ownCloud, Nextcloud continues taking on the likes of Dropbox, Google Docs, and Microsoft 365 -- especially more so now with their introduction of Nextcloud Hub. Nextcloud Hub is a completely integrated on-premises content collaboration platform...

We'll likely see the Wine 5.0 stable release next week or the following week, but for now Wine 5.0-RC6 is available as the newest weekly release candidate...

Fedora CoreOS has graduated out of its preview state and is now considered ready for general use...

This week our AMD Ryzen 9 3950X review sample finally arrived and so we've begun putting it through the paces of many different benchmarks.

Xiph.org's Rustlang-written "Rav1e" AV1 video encoder is back on track with delivering weekly pre-releases after missing them over the past month due to the holidays. With Rav1e p20200115 are not only performance improvements but also binary side and build speed enhancements...

It's been another day testing and investigating CVE-2019-14615, a.k.a. the Intel graphics hardware issue where for Gen9 all turned out to be okay but for Gen7 graphics leads to some big performance hits. Besides the Core i7 tests published yesterday in the aforelinked article, tests on relevant Core i3 and i5 CPUs are currently being carried out for seeing the impact there (so far, it's looking to be equally brutal)...

Mir 1.7 was released today as the newest feature release for this Ubuntu-focused display stack that for the past two years now has focused on serving viable Wayland support...

One of the few frustrations with the AMD Ryzen CPU support on Linux to date has been besides the often delayed support for CPU temperature reporting has been the mainline kernel not supporting voltage readings and other extra sensors. But that is finally changing with the "k10temp" driver being extended to include current and voltage reporting plus CCD temperature reporting on Zen 2 processors...

The release of CentOS 8 came several months after RHEL 8.0 and this week's release of CentOS updated against RHEL 8.1 took over two months of work. But moving forward to RHEL 8.2 and beyond, that turnaround time will hopefully be less...

GNU Guile 3.0 has been released, the GNU's implementation of the Scheme programming language with various extra features. The big news with Guile 3.0 is better performance...

Disclosed back in November was the Intel Jump Conditional Code Erratum that necessitated updated CPU microcode to mitigate and with that came with a nearly across the board performance impact. But Intel developers had been working on assembler patches for helping to reduce that performance hit. The GNU Assembler patches were merged back in December while now ahead of LLVM 10.0 that alternative toolchain has an option for helping to recover some of the lost performance...

Now that lead WireGuard lead developer Jason Donenfeld has managed to get this secure VPN tunnel technology queued for introduction in Linux 5.6 mainline, he's begun optimizing other areas of the kernel for optimal WireGuard performance...

LLVM project founder Chris Lattner has proposed a new decision making process for the LLVM compiler stack around new sub-project proposals, new social policies, changes to core infrastructure, and other key changes...

Yesterday we noted that the Linux kernel picked up a patch mitigating an Intel Gen9 graphics vulnerability. It didn't sound too bad at first but then seeing Ivy Bridge Gen7 and Haswell Gen7.5 graphics are also affected raised eyebrows especially with that requiring a much larger mitigation. Now in testing the performance impact, the current mitigation patches completely wreck the performance of Ivybridge/Haswell graphics performance.

As we mentioned back in December, a Kubuntu-powered laptop is launching with the blessing of Canonical and the Kubuntu Community Council. That laptop, the Kubuntu Focus, will begin shipping at the beginning of February while the pre-orders opened today as well as the embargo lift. We've been testing out the Kubuntu Focus the last several weeks and it's quite a polished KDE laptop experience for those wanting to enjoy KDE Plasma for a portable computing experience without having to tweak the laptop for optimal efficiency or other constraints.

CentOS 8 1911 has been released today as the community rebuild rebased to Red Hat Enterprise Linux 8.1 that debuted back in November...
