Oracle Continues Working On eBPF Support For GCC 10

Back in May we wrote about Oracle's initial plans for introducing an eBPF back-end to GCC 10 to allow this GNU compiler to target this general purpose in-kernel virtual machine. Up to this point LLVM Clang has been the focused compiler for eBPF but those days are numbered with Oracle on Friday pushing out the newest GCC patches.

Unigine 2.9 Further Enhances Its Stunning Visuals

It's a pity there doesn't seem to be any new adoption of Unigine as a game engine, but this visually impressive platform does continue seeing much success in the area of industrial simulations, professional VR platforms, and related areas. With Unigine 2.9 this Linux-friendly graphics engine is even more stunning.

Etnaviv Is Packing Code For An Exciting Linux 5.4 Cycle

While Freedreno and Panfrost have been steaming ahead when it comes to open-source, reverse-engineered graphics for Arm SoCs, the Etnaviv project for targeting Vivante graphics hasn't had too much to report on recently. Fortunately, that's changing as coming up for the Linux 5.4 cycle they have a lot of new code to introduce.

Microsoft's Component Firmware Update Is Their Latest Short-Sighted Spec

Microsoft's newest specification is the "Component Firmware Update" that they envision as a standard for OEMs/IHVs to be able to handle device firmware/microcode updating in a robust and secure manner. While nice in theory, the actual implementation has a number of issues that complicate the process and could quickly evolve into another troubling specification from Microsoft in the hardware space.

AMD Bulldozer/Jaguar CPUs Will No Longer Advertise RdRand Support Under Linux

Not directly related to the recent AMD Zen 2 BIOS update needed to fix an RdRand problem (though somewhat related in that the original systemd bug report for faulty AMD RdRand stems from these earlier CPUs), but AMD has now decided to no longer advertise RdRand support for Family 15h (Bulldozer) and Family 16h (Jaguar) processors under Linux.

Oracle Is Working To Upstream More Of DTrace To The Linux Kernel & eBPF Implementation

While DTrace prospects for the Linux kernel are no longer viewed as magical or groundbreaking as they once were more than a decade ago, Oracle continues to work on its DTrace port to Linux and extending its reach beyond just their "Unbreakable Enterprise Kernel" for their RHEL-cloned Oracle Linux. Oracle now says they are working towards upstreaming more work as well as getting an eBPF-based implementation for the kernel.

Clear Linux Rolls Out Revamped Documentation

While Arch Linux remains the gold standard for quality Linux documentation, Intel's Clear Linux has rolled out a new documentation web-site to assist new/existing users in making use of this performance-optimized and security-oriented Linux operating system.

Blender 2.80 Performance With Intel Xeon Platinum 8280 vs. AMD EPYC 7742

The Blender 2.80 release arrived at the end of July that unfortunately was too late for using that big new release in our launch-day testing of AMD's EPYC 7002 "Rome" processors but as a follow-up here are AMD EPYC 7742 performance benchmarks up against the Intel Xeon Platinum 8280 Cascade Lake as well as the AMD EPYC 7601 2P. Blender 2.80 performance is the focus of this article along with some other renderer benchmarks.

FreeBSD 13 Is Preparing To Finally Retire GCC 4.2

GCC 4.2.1 has been out since 2007 and while there have been many big updates to the GNU Compiler Collection over the past decade, that version remains somewhat common in the BSD land due to being the last version under the GPLv2 license. GCC 4.2.2 and newer switched over to GPLv3+ and that is why several BSDs have stuck to using GCC 4.2.1 or at least keeping it in their base repository. But now for FreeBSD 13, this old version of GCC is set to be retired with FreeBSD already being quite focused on LLVM Clang as its default compiler while also offering newer GCC versions via its package management system.

Building The Default x86_64 Linux Kernel In Just 16 Seconds

It's now been one week since the launch of AMD's EPYC Rome processors with up to 64 cores / 128 threads per socket and better IPC uplift compared to their previous-generation parts. Rome has outperformed Intel Xeon Scalable CPUs in their class while offering better power efficiency and way better performance-per-dollar. One of my favorite metrics has been how quickly the new EPYC 7742 2P can build the Linux kernel.

Cooling The Raspberry Pi 4 With The Fan SHIM & FLIRC For Better Performance

With the Raspberry Pi 4, a passive heatsink is an absolute minimum for running this new ARM SBC unless you want to deal with potentially drastic performance limitations based upon your operating conditions. However, if you will be enduring the Raspberry Pi 4 with significant load for any measurable length of time, an active cooler is almost warranted or otherwise a very capable passive cooler. In this article we're looking at the Raspberry Pi 4 performance with a Fan SHIM as an active fan designed for running on the Raspberry Pi off the GPIO pins as well as the FLIRC as a metal case that passively cools the device.
