Earlier this month when Intel disclosed CVE-2019-14615 as a security vulnerability affecting their graphics architecture, older Gen7 graphics saw a huge hit to their performance with the initial patches for addressing this vulnerability on Ivy Bridge and Haswell processors. Fortunately, a new mitigation patch series was sent out this week where they believe the performance costs are now avoided...

We've seen a lot of odd products pick up the Free Software Foundation's "Respect Your Freedom" endorsement like a USB microphone, various re-branded motherboards, and even last year certified a USB to parallel printer cable. The latest product they are endorsing -- and their first endorsement of 2020 -- is a USD 802.11 a/b/g/n PCIe half-mini card starting out at $59 USD but going up to $79 for this outdated wireless adapter...

Among many other Valve ACO back-end improvements for Mesa 20.0, one of the notable additions is this AMDGPU LLVM alternative now working for Radeon "Southern Islands" / GCN 1.0 graphics cards. With this, these original AMD GCN graphics cards may have some extra life out of Linux gaming boxes thanks to slightly higher performance some eight years after these graphics cards first launched in the Radeon HD 7000 series.

While WireGuard was merged into Linux 5.6, the Ubuntu 20.04 LTS release is currently tracking Linux 5.4 and for the April release is likely to be shipping with Linux 5.5 as the 5.6 release will be cutting it too close. But Ubuntu 20.04's kernel has now back-ported WireGuard...

With LLVM Clang 10 having added a Zen 2 scheduler model tuned for the latest AMD CPUs over the existing "znver2" tuning that had just copied the Zen 1 scheduler, here are some benchmarks looking at the LLVM Clang 9 vs. 10 compiler performance on AMD EPYC when making use of "-march=znver2" optimizations...

Since the stable release of Linux 5.5 this weekend I have been carrying out benchmarks for looking at how the performance of this newly-minted kernel compares to older releases. Here are benchmark results of Linux 5.3 vs. 5.4 vs. 5.5 with an AMD Ryzen Threadripper 3970X but the results are similar to other HEDT and lower-end systems we've tested thus far...

With LLVM Clang 9.0 and Linux 5.3 together it became possible to build the mainline Linux kernel with this non-GCC compiler. The x86_64 Linux kernel Clang-based kernel builds has continued to improve through newer kernel releases. This follows the mainline AArch64 (64-bit ARM) Linux kernel mainline build by Clang too, which has been of much interest by different hardware/software vendors. There hasn't been much Clang'ing kernel efforts for other architectures, but it turns out with Clang 10 and Linux 5.6 will be another working combination, this time for IBM s390...

The Time Namespace, which was originally proposed back in 2018 for allowing per-namespace offsets to the system clocks, has finally entered the mainline kernel in early 2020 with the in-development Linux 5.6 kernel...
