Back at SC19 Intel released a beta of their oneAPI Base Toolkit for software developers to work on performance-optimized, cross-device software. Complementing that initial software beta is now the oneAPI Level 0 Specification...
Since the AMD EPYC 7002 "Rome" series launch in August we have continue to be captivated by the raw performance of AMD's Zen 2 server processors across many different workloads as covered now in countless articles. The performance-per-dollar / TCO is also extremely competitive against Intel's Xeon Scalable line-up, but how is the power efficiency of these 7nm EPYC processors? We waited to deliver those numbers until having a retail Rome board for carrying out those tests and now after that and then several weeks of benchmarking, here is an extensive exploration of the AMD EPYC 7002 series power efficiency as well as a look at the peak clock frequencies being achieved in various workloads to also provide some performance-per-clock metrics compared to Naples.

For years there has been work on a Wayland back-end to Ozone, the Google component for abstracting user-interface elements and input/window handling among other tasks across platforms. It looks like in 2020 the Ozone Wayland support will be in good standing and promoted out of beta...
With each new release of Firefox we set out to see how the performance is looking on the Linux desktop. One discovery we've made is that when using Intel's Clear Linux the Firefox performance is a lot more competitive to Google Chrome than we traditionally see on Ubuntu Linux. But with Firefox 71 we're seeing the performance trending lower compared to Firefox 69 and 70...
For those looking to spend less than $200 USD on a graphics card, the recently launched NVIDIA GeForce GTX 1650 SUPER offers great value starting at $159 USD and working well with the NVIDIA Linux driver for providing decent 1080p Linux gaming performance as well as OpenCL / CUDA support. Here are benchmarks of the GTX 1650 SUPER alongside a total of 18 lower-end/mid-range AMD Radeon and NVIDIA GeForce graphics cards on Ubuntu Linux.

Longtime open-source AMD graphics driver developer Marek Olšák has kicked off a discussion over the possibility in the not too distant future of either dropping non-Gallium3D drivers from Mesa (and moving them off to a maintenance branch or the like) or forking some of Mesa's existing code to allow it to be better optimized for Gallium3D use-cases. Due to raised concerns, other possibilities are also being expressed like simply moving ahead with optimizing the Mesa code-base for Gallium3D at a cost of potentially hitting dead code more often with the classic drivers...
The RadeonSI Gallium3D driver has finally landed SDMA copy support for Vega/GFX9 graphics hardware, which should principally benefit compute shaders and other cases...
With the PowerPC changes for the Linux 5.5 kernel comes the initial infrastructure work on preparing to be able to handle a Secure Boot implementation for POWER9 hardware...
ASPM can be a big boost to help power-savings on Linux laptops and desktops as shown by a prominent kernel regression a number of years ago. However, a number of Linux drivers are forced to disable Active State Power Management (ASPM) due to quirky/buggy hardware where it ends up not being sane to enable that power-saving feature by default. But with the Linux 5.5 kernel is support for toggling ASPM link states via sysfs as an easy-to-perform manner for achieving better power-savings with friendly devices...
Taking place back in September at Google and Facebook facilities was the Open-Source Firmware Conference (OSFC 2019). For those not able to attend, video recordings of those talks are now freely available online...

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...
