Now that the new AMD Ryzen 3000 series are running great with the latest Linux distributions following prominent motherboard vendors issuing BIOS updates that correct the "RdRand" issue, we're moving on with looking at the performance of the rest of the Ryzen 3000 series line-up while having freshly re-tested the processors under Ubuntu 19.04. Up for exploration today is the AMD Ryzen 5 3600X, the six-core / 12-thread processor retailing for about $250 USD.

Intel previously tried auto-enabling GuC and HuC functionality within their Linux kernel graphics driver but ended up reverting the support since the driver didn't gracefully handle the scenarios of missing/corrupt firmware files. The driver should now be more robust in such situations so they will try again for turning on the automatic behavior, possibly for the upcoming Linux 5.4 cycle...

Following the feature freeze and code branching for Qt 5.14, the Qt "Dev" branch will likely be shifting immediately to Qt 6 development. A Qt 5.15 release is still expected to happen before Qt 6.0, but that 5.15 milestone will likely just be a polished release derived from Qt 5.14...

Going back a decade one of the interesting open-source FPS games of its time was Warsow. Development on Warsow has seemingly been tremulous over the past few years (edit: though the core developer has recently released a new beta) for this Qfusion (Quake 2 code base) engine powered game that started in 2005, but now there is Warfork as a fork of Warsow that is being developed and also available via Steam...

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...

Intel has released a new version of their SYCL compiler and run-time code for single-source C++ programming and allowing offloaded computations to accelerators via OpenCL...

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...

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...

LLVM 9.0 Release Candidate 2 is now available for testing while LLVM 10.0 has switched its code-base over to supporting C++14...

Last week AMD sent out their initial Linux graphics driver support for next-gen Renoir APUs. Those Linux kernel bits will land with AMDGPU in the upcoming Linux 5.4 cycle while the RadeonSI changes were merged today marking that OpenGL support as a new feature for the upcoming Mesa 19.2...

EPEL 8.0 is now ready for users of Red Hat Enterprise Linux 8 and the eventual CentOS 8 for complementing the standard repositories with extra packages for what is found in Fedora...

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.

Continuing on from the recent technical vision for the Qt6 tool-kit, The Qt Company has now announced their new high-level 3D API they are developing for this next major release of Qt...

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...

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...

With TrueOS (formerly PC-BSD) no longer focused on delivering a quality BSD desktop as they once did, while there still are options out there for a desktop-focused BSD like MidnightBSD, for those wanting to use a vanilla FreeBSD installation can now setup a desktop easier using a new script...

The Apache Software Foundation has published their 2019 fiscal year report highlighting their more than 350 open-source projects/initiatives and this also marks their 20th anniversary...

Up until today the newest Linux kernel version supported by the official Reiser4 out-of-tree file-system driver patch was Linux 5.0, but that has now changed with the belated Linux 5.1 kernel support arriving as well as a separate patch for Linux 5.2 kernel support...

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.

NVIDIA this morning introduced their 435 Linux driver series currently in beta form with the release of the 435.17 Linux build. With this new driver comes finally the best PRIME/multi-GPU support they have presented to date...
