Samsung 970 EVO Plus 500GB NVMe Linux SSD Benchmarks

Announced at the end of January was the Samsung 970 EVO Plus as the first consumer-grade solid-state drive with 96-layer 3D NAND memory. The Samsung 970 EVO NVMe SSDs are now shipping and in this review are the first Linux benchmarks of these new SSDs in the form of the Samsung 970 EVO Plus 500GB MZ-V7S500B/AM compared to several other SSDs on Linux.

No Surprise But Intel Linux Developers Are Working Towards Adaptive-Sync Support

Back during the Intel Architecture Day event in December, Intel confirmed that finally with Icelake "Gen 11" graphics there is Adaptive-Sync support after talking about it for several years. While they didn't explicitly mention Linux support, they've been largely spot on for years with supporting new display features on Linux and this should be the case as well with Adaptive-Sync and their next-generation graphics.

Microsoft Developer: You Still Should Have Anti-Virus With Windows Subsystem For Linux

While disabling Windows Defender or other anti-virus programs may partially help offset the performance losses imposed by running Windows Subsystem for Linux, a.k.a. "Bash for Windows" or Ubuntu and other distributions running natively atop Windows 10 and now Windows Server 2019, it's not the root cause of the I/O performance bottleneck and is not a recommended course of action.

AMD_DEBUG Can Now Be Used In Place Of R600_DEBUG For RadeonSI Options

When setting various debug options for the RadeonSI Gallium3D driver -- like enabling its NIR back-end among many other options -- that has traditionally been done through the R600_DEBUG= environment variable. But that variable name makes little sense these days since RadeonSI doesn't even support the now-vintage R600 GPUs. Thankfully, AMD_DEBUG= is now a supported alternative.

GCC 8/9 vs. LLVM Clang 7/8 Compiler Performance On AArch64

With Clang 8.0 due out by month's end and GCC 9 due for release not long after that point, this week we've been running a number of GCC and Clang compiler benchmarks on Phoronix. At the start of the month was the large Linux x86_64 GCC vs. Clang compiler benchmarks on twelve different Intel/AMD systems while last week was also a look at the POWER9 compiler performance on the Raptor Talos II. In this article we are checking out these open-source compilers' performance on 64-bit ARM (AArch64) using an Ampere eMAG 32-core server.

Unreal Engine 4.21 back in November was a big update for Linux gamers in that this game engine now defaults to the Vulkan renderer and also had various other fixes. With today's Unreal Engine 4.22 Preview 1 release, there are no Linux/Vulkan-specific changes mentioned, but some other interesting changes in general.

Ubuntu Developers Seem To Be Really Pursuing ZFS Root Partition Support On The Desktop

Earlier this month I reported on how Ubuntu developers indicated they were looking at ZFS support on the desktop as part of their work developing the new Ubuntu desktop installer GUI. It's quite clear now that they are indeed pursuing the work to allow Ubuntu desktop installs via their work-in-progress installer to support ZFS root installations.

Radeon VII (Vega 20) Firmware Support Lands In Linux-Firmware.Git

In addition to needing a recent version of the Linux kernel and Mesa (ideally, Linux 5.0 and Mesa 19.0 if enjoying the very best performance and features) for using a Radeon VII graphics card on Linux, you also need to have the necessary firmware binaries manually installed if not using the Radeon Software for Linux driver package. Those firmware bits are now in the linux-firmware.git repository.

Fedora 31 Should Be Out Around The End of November

While Fedora 31 was once talked about to never happen or be significantly delayed to focus on re-tooling the Linux distribution, they opted for a sane approach not to throw off the release cadence while working on low-level changes around the platform. A draft of the release schedule for Fedora 31 has now been published and it puts the release date at the end of November.
