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...

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...

While Fedora 30 isn't debuting for another three months, with the system-wide change deadline already having passed on that release, ambitious Fedora developers are already thinking about early feature plans for Fedora 31 that will debut in November...

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...

The Nouveau kernel driver tree where development happens on this open-source NVIDIA DRM driver saw a fresh batch of changes on Tuesday in aiming for new material with Linux 5.1...

The latest weekly release candidate of Mesa 19.0 is now available for testing, but it's a very petite release due to failing to include all of the latest back-ported patches intended for this release...

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...

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...

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...

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...

Right now on most Linux distributions when using higher-end Bluetooth headphones, the low-end SBC audio codec ends up being utilized by default which is subpar for the potential audio quality of the more expensive headphones. Fortunately, there are PulseAudio modules that allow for the higher-end codecs to be used...

Fedora's Engineering and Steering Committee approved new work around the in-development Fedora 30...

At the end of January, Dell announced the Dell XPS 13 9380 Developer Edition laptop as an upgraded version of the XPS 9370 with now having Intel Whiskey Lake CPUs and other minor improvements. Over the past two weeks I've been testing out the Dell XPS 9380 with Intel Core i7 8565U processor with 256GB of NVMe SSD storage and 16GB of RAM. Here are benchmarks of the Dell XPS 9380 compared to several other laptops running Ubuntu Linux as well as looking at the system thermal and power consumption among other metrics.

We've been looking forward to the possibility of having a nice 64-bit ARM Linux laptop with decent power and nice build quality. Several major vendors having been rolling out Windows ARM laptops powered by Qualcomm chips and the like with decent specs and quality, unlike some of the cheap ARM Linux laptop efforts we've seen. For those Windows ARM laptops, headway is being made in being able to run Linux on them...

It's been a number of months since last trying the RadeonSI NIR back-end, which is being developed as part of the OpenGL 4.6 SPIR-V bits for this AMD OpenGL driver, but eventually RadeonSI may end up switching from TGSI to NIR by default. Given the time since we last tried it out and the increasing popularity of NIR, this weekend I did some fresh tests of the NIR back-end with a Radeon Vega graphics card.
