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...

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...

While IBM has their own in-house XL C/C++ compiler for their AIX operating system and GCC is also supported there too, IBM engineers are looking at adding AIX support to LLVM/Clang...

HHVM, formerly known as the HipHop Virtual Machine and what was born at Facebook as a higher-performance PHP implementation only to shift focus to running their own PHP-derived Hack programming language, has reached version 4.0 as it officially no longer supports PHP...

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.

With the feature freeze for KDE Applications 19.04 happening next month in order to meet the planned 18 April release date, KDE developers are busy getting their new features ready and reviewed for this next round of application updates...

The Apple MacBook / MacBook Pro laptops of the past few years have been notoriously bad on Linux at least as far as the mainline / out-of-the-box support is concerned. The current MacBook's keyboard and touchpad don't even work out-of-the-box on Linux. There has been an out-of-tree driver available for changing that while coming soon it might finally be merged to the mainline kernel...

One bit of Intel consumer hardware support not currently handled by the Linux kernel was for their Cherry Trail Whiskey Cove PMIC LEDs -- that's for the LEDs connected to their power-management IC on various laptops...

RISC-V remains of a lot of interest to open-source/Linux users for being a royalty-free and completely open CPU architecture. In part due to the lack of affordable RISC-V hardware limiting developers from working more on this architecture, the state of RISC-V support by Linux distributions varies but at least has improved a lot in recent years...

The long-awaited OpenMandriva Lx 4.0 distribution update entered alpha for Christmas and this weekend was finally succeeded by the Lx 4.0 Beta 1 milestone...

Back in our NVIDIA Jetson AGX Xavier benchmarks from December, besides looking at the incredible Carmel+Volta GPU compute potential for machine learning and other edge computing scenarios, we also looked at the ARMv8 Carmel CPU core performance against various other ARM SoCs on different single board computers. But how do these eight NVIDIA Carmel CPU cores compare to x86_64 low-power processors? Here are some of those benchmarks for those curious about the NVIDIA CPU potential.

Intel's Open-Source Technology Center has published a whitepaper looking at the Android application performance impact on Intel-powered Chromebooks when the Android Bionic Library is optimized for AVX2...

The Electron software framework that allows creating desktop GUI application interfaces using JavaScript and relies upon a bundled Chromium+Node.js run-time is notorious among most Linux desktop users for being resource heavy, not integrating well with most desktops, and generally being despised. For those that are fond of using web standards for creating desktop GUIs, now there is a way to create desktop application front-ends using HTML5 and Golang but with less baggage...
