Going on for months had been work by Intel Linux developers on supporting the FSGSBASE instruction for helping Intel CPU performance going back to Ivybridge where this instruction set extension was first introduced. The FSGSBASE support was queued for the Linux 5.3 kernel but was reverted due to "serious bugs" in the implementation. Intel has now published a revised version of this support...

With the upcoming LLVM Clang 9.0 compiler release there is an amazing achievement more than a decade in the making... The mainline Clang compiler can finally build the mainline Linux x86_64 kernel. The AArch64 state has been in better shape in recent years with multiple Arm vendors using Clang as their default compiler including to build the Linux kernel, but finally in 2019 the mainline Clang can build mainline Linux x86_64. There are a few caveats, but in this article is my experience in doing so with LLVM Clang and the Linux 5.3 kernel as well as running some preliminary benchmarks on AMD and Intel hardware.

In our recent Mesa 19.2 benchmarks of Intel's old and new (Gallium3D) OpenGL Linux drivers one of the rare areas where the new "Iris" driver performed behind the classic driver was with "j2dbench" that stresses the Java OpenGL pipeline. At the time it was unknown why the new driver was performing subpar for this Java graphics test, but now at least there's one optimization so far in addressing that shortcoming...

The past month and a half we have been putting CompuLab's Airtop 3 computer through some demanding benchmarks and a variety of endurance workloads. With the Airtop 3 under test loaded with an 8-core / 16-thread Xeon processor, NVIDIA Quadro RTX 4000 graphics, and 64GB of RAM with NVMe SSD storage there were some concerns over thermal throttling and if this fan-less industrial PC design could really deal with the generated heat. But after all of this testing, the Airtop 3 continues running strong and another shining example of CompuLab's engineering strength.

The next-generation AMD "Renoir" APU is turning into being an interesting successor over the existing Picasso APUs. While at first it was a letdown finding out that the APU is based on Vega and not their newer Navi architecture, follow-on open-source Linux patches have continued to show that it's more than a facsimile and in some areas like display and multimedia has blocks in common with Navi...
