Extensive Benchmarks Looking At AMD Znver1 GCC 9 Performance, EPYC Compiler Tuning

With the GCC 9 compiler due to be officially released as stable in the next month or two, we've been running benchmarks of this near-final state to the GNU Compiler Collection on a diverse range of processors. In recent weeks that has included extensive compiler benchmarks on a dozen x86_64 systems, POWER9 compiler testing on the Talos II, and also the AArch64 compiler performance on recent releases of GCC and LLVM Clang. In this latest installment of our GCC 9 compiler benchmarking is an extensive look at the AMD EPYC Znver1 performance on various releases of the GCC compiler as well as looking at various optimization levels under this new compiler on the Znver1 processor.

Gallium Nine With NIR Is Now Running Most D3D9 Games "Flawlessly"

Towards the beginning of the month we reported on the Gallium Nine state tracker working on NIR support as an alternative to its original focus on the common TGSI intermediate representation to Gallium3D. That NIR-ified version of Gallium Nine is now working and beginning to run most Direct3D 9 games fine.

Using Clear Linux As A Desktop Linux Distribution - It Works Well But With Some "Papercuts"

While I am a big fan of Intel's Clear Linux distribution for its raw performance on x86_64 hardware that for most workloads goes unsurpassed by any other Linux platform out-of-the-box, there has been a lot of Phoronix readers wondering how well it could function as a standard desktop Linux distribution. With upgrading my main production system earlier this month, I decided to try out Clear Linux and now with 200+ hours into using it as the OS on my main production system, I figured it'd be good to share my initial thoughts.

Linux Seeing Support For The HyperBus

The Linux kernel is in the process of receiving support for the HyperBus, a high performance DDR bus interface used for connecting the processor/controller/ASIC to "HyperFlash" flash memory or "HyperRAM" DRAM.

It's Still Undecided Whether Ubuntu 20.04 LTS Will Support 32-bit x86 (i386)

Ubuntu 17.10 dropped its i386 / 32-bit x86 installer image while the i386 port has remained part of the package archive. Other Ubuntu derivatives over the past year have also moved to drop their 32-bit installer images and with Lubuntu/Xubuntu now ending their ISOs for that port, it's hitting the end of the road. Now for Ubuntu 20.04 LTS, there might not even be the i386 port.

Linux 5.0 I/O Scheduler Benchmarks On Laptop & Desktop Hardware

Our past tests have shown that while most Linux distributions default to "none" for their I/O scheduler on NVMe solid-state storage, that isn't necessarily the best scheduler decision in all cases. Here are tests using the Linux 5.0 Git kernel using laptop and desktop hardware while evaluating no I/O scheduler, mq-deadline, Kyber, and BFQ scheduler options.

Chamferwm: A Vulkan-Powered X11 Window Manager

While we have talked about the possibilities of writing a Vulkan Wayland compositor and there was even a short-lived Vulkan renderer for KDE's KWin, it's also possible to write a X11 window manager around the Vulkan interfaces.

Fedora 31 Planning To Use Cgroups V2 By Default

While the Linux kernel has shipped Cgroups V2 as stable since early 2016, on Fedora and most other Linux distributions it hasn't been enabled by default over the original control groups "Cgroups" implementation. But come Fedora 31 later this year, they are now planning to make it the default.
