While Clear Linux as part of its standard bare metal installations has long defaulted to having an AVX2-optimized GNU C Library installed by default, it turns out that it wasn't part of the default os-core bundle as used by containers. That though is changing and should yield even better out-of-the-box performance when running Clear Linux within containers...

Intel Software Guard Extensions "SGX" have been around since Skylake for allowing hardware-protected (via encryption) memory regions known as "enclaves" that prevent processes outside of the enclave from accessing these memory regions. While supported CPUs have been out for years, the Intel SGX support has yet to make it into the mainline kernel and this week marks the twenty-first revision to these patches...

The past few weeks while AMD open-source developers were busy getting their Navi enablement code public and aligned for the Linux 5.3 merge window, the display core "DC" frequent code drops ceased. Every so often AMD developers volley their DC patches from their internal development trees to the public mailing list for queuing ahead of the next cycle. Now that Navi is out there and getting stabilized, they've issued a new set of DC patches and it's coming in heavy...

Speed Select Technology allows optimizing the system with per-core performance configurations to prioritize certain workloads while lowering the performance envelope for other cores...

AMD Zen 2 processors feature hardware-based mitigations for Spectre V2 and Spectre V4 SSBD while remaining immune to the likes of Meltdown and Zombieload. Here are some benchmarks looking at toggling the CPU speculative execution mitigations across various Intel and AMD processors.

For those in the market for an AMD X570 high-end motherboard for use with the new Zen 2 processors, the ASUS ROG CROSSHAIR VIII HERO was one of the boards sent out as part of the reviewer's kit and it's been working out quite well...

At 479,818 lines of new code and just 36,145 lines of code removed while touching nearly two thousand files, the Direct Rendering Manger (DRM) driver updates for Linux 5.3 are huge. But a big portion of that line count is the addition of AMD Radeon RX 5000 "Navi" support and a good portion of that in turn being auto-generated header files. Navi support is ready for the mainline Linux kernel!..

With more tier-one Linux distributions working on plans for doing away with 32-bit x86 support, if you are looking for a new distribution to play nicely with older hardware, Q4OS 3.8 may be it...

The char/misc changes with each succeeding kernel release seem to have less changes to the character device subsystem itself and more just a random collection of changes not fitting in other subsystems / pull requests. With Linux 5.3 comes another smothering of different changes...

While OpenMandriva Lx 4.0 was just released last month, we are already looking forward to OpenMandriva 4.1 for a number of improvements and some new features...

For those using the NVIDIA proprietary graphics driver on an IBM POWER system, it could be a while before seeing Linux 5.3+ kernel support. Upstream has removed code depended upon by the NVIDIA binary driver for supporting the POWER architecture and as is the case they don't care that it will break NVIDIA driver support since it's binary/out-of-tree...
