While originally Intel planned to transition their OpenGL driver default to the modern "Iris" Gallium3D driver rather than the longstanding "i965" DRI driver for Mesa 19.3, that was pushed back to Mesa 20.0 for introduction in Q1'2020. In aiming to make that revised milestone a reality, a new option has been added to Mesa 20.0 with the Meson build system for being able to indicate the Intel OpenGL driver preference...

While there has been the Libre RISC-V community-driven effort to create a RISC-V graphics processor that basically amounts to a RISC-V core with vector extensions/improvements and running a Vulkan software implementation (though they are now reportedly eyeing POWER instead of RISC-V), Think Silicon has announced the first actual RISC-V ISA based 3D graphics processor...

For those of you interested in AMD's new Ryzen Threadripper 3960X/3970X processors with TRX40 motherboards for running FreeBSD, the experience in our initial testing has been surprisingly pleasant. In fact, it works out-of-the-box which one could argue is better than the current Linux support that needs the MCE workaround for booting. Here are some benchmarks of FreeBSD 12.1 on the Threadripper 3970X compared to Linux and Windows for this new HEDT platform.

NetBSD 9.0 is around the corner and finally presenting 64-bit Arm (AArch64) support as well as other long overdue hardware support like Intel Kabylake graphics...

With the Linux 5.4 cycle we saw mainline support beginning to come together for some Qualcomm ARM Linux laptops while with Linux 5.5 another milestone is being achieved. There has been out-of-tree support in the works for getting the various consumer Snapdragon laptops working with Linux while those changes are slowly getting into the mainline kernel...

With the IOMMU updates for the Linux 5.5 kernel there is a major rework to the AMD IOMMU driver to make use of more common DMA IOMMU code for implementing the DMA API but with an admitted risk of potential new regressions...

With the start of a new month always comes the excitement of seeing what Valve's Steam Survey is pointing at for gaming trends as to the percentage of Linux gamers...

While there still is a week to go in the Linux 5.5 merge window with more feature code still landing, due to scheduler changes and other work already having landed, I already started running some Git benchmarks. Linux 5.5 at this stage appears quite volatile with some really nice improvements in some workloads but also regressions in others...

A month ago at the Open-Source Summit Europe 2019 in Lyon, France, Intel's Kelly Hammond who serves as the company's Senior Director of System Platform Software talked up their open-source contributions with a particular emphasis on performance. The video from that keynote was recently published for those curious about Intel's open-source work in the name of performance, including Clear Linux...

And there's a new Phoronix worker in-training...

The Kernel-based Virtual Machine (KVM) improvements were sent in earlier this week for the Linux 5.5 kernel and they appear to be busier than usual on the x86 (Intel / AMD) side for the open-source virtualization stack...

When the Raspberry Pi 4 launched earlier this year it was quickly realized active cooling was almost required if wanting to run the quad-core Cortex-A72 SoC at full performance without thermal throttling. Fortunately, the latest Raspberry Pi 4 firmware has improved the thermal/power behavior to lessen the need for extra cooling although it's still recommended for achieving peak performance potential out of this popular low-cost ARM SBC...

With the AMD Ryzen Threadripper 3970X benchmarks on Windows 10 and Linux, Ubuntu 19.10 and other common distributions were just ~2% faster than the Microsoft OS and Clear Linux was just ~10% faster, based on 80+ benchmarks carried out. Those margins are much closer than we have seen with past iterations of Threadripper, but is that due to the Zen 2 microarchitecture and the improved topology of the new Threadripper CPUs or due to Microsoft's scheduler changes and other software improvements made in Windows 10 November 2019 Update? Here are some benchmarks...

The HID area of the kernel is always eventful when it comes to improving the input device support for newer hardware. With Linux 5.5 the HID story means a new Logitech driver and other enhancements...

The new AMD Ryzen Threadripper 3970X is performing faster on Linux than Microsoft Windows 10. When carrying out more than 80 different tests on Windows 10 compared to five Linux distributions, Windows 10 was beat out by the open-source competition. However, the performance loss for Windows isn't as dramatic as we have seen out of earlier generations of Ryzen Threadripper HEDT workstations. Here are those benchmarks of Windows 10 compared to Ubuntu 19.10, CentOS 8, Clear Linux, Fedora Workstation 31, and openSUSE Tumbleweed.

Systemd has a present for you with a new release that comes bearing more features for this Linux init system...

Reported on earlier this month is the decision by Linux kernel developers to disable HPET for Intel Coffee Lake systems. The High Precision Event Timer was being disabled since on some Coffee Lake systems at least this timer skews when entering the PC10 power state and that makes the time-stamp counter unstable...
