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...

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...

Coming to Linux last year with the 5.3 kernel was Intel Speed Select Technology support as a Cascade Lake feature for optimizing the per-core performance configurations to favor certain cores at the cost of reducing the performance capacity for other CPU cores. That Intel Speed Select (SST) support for Linux is now being enhanced with core-power controls...

Earlier today we were first to report on an Intel graphics driver patch mitigating a "Gen9" graphics hardware vulnerability. Details on that new security disclosure are coming to light and it turns out older Intel "Gen" graphics are also affected...

Longtime Red Hat developer Richard Jones has begun developing "Goals" as a new tool to improve upon Make, the common build automation tool...

It's too bad that it has taken so many months after AMD Zen 2 based Ryzen and EPYC processors began shipping to see this compiler support in place, but the good news now is that for the upcoming release of LLVM 10.0 is now the Zen 2 scheduler model being added to the "znver2" target...

Last week marked the two year anniversary since the formal public disclosure of the Spectre and Meltdown disclosures. To commemorate that anniversary, I was running some fresh benchmarks of various Intel desktop and server processors with the in-development Ubuntu 20.04 LTS to look at the performance impact today with the default CPU vulnerability mitigations and then again with the mitigations disabled at run-time.
