For the past year "Zink" has been in development as the OpenGL API implemented over Vulkan and done as a Gallium3D driver. That code by Collabora's Erik Faye-Lund will likely be merged to Mesa 19.3 in the coming weeks...

Following the Spectre mitigations coming to light last year, the late microcode update process for CPUs was serialized. However, this has led to complaints from cloud vendors and other customers with large core count servers where downtime/disruptions need to be minimal. So now the CPU microcode update process is being parallelized again...

Neil Trevett, the president of the Khronos Group, presented at the X.Org Developers' Conference for the first time. During his presentation on Wednesday he covered their usual initiatives, how Khronos engages in open-source and open standards, and related bits -- plus a few interesting ones...

Not particularly surprising considering Fedora tends to always ship with a bleeding-edge toolchain, but for their Fedora 32 release to kick off 2020 they are planning for GNU Binutils 2.33...

One of the interesting reveals so far from this week's X.Org Developers' Conference in Montreal is that Intel has been developing a new back-end compiler for their OpenGL/Vulkan Linux drivers based upon their experiences so far with their NIR support and the lessons learned over the past number of years...

Intel's open-source crew has had a busy week with their first public OpenVKL release, OSPray 2 hitting alpha, and now the release of MKL-DNN where they are also re-branding it as the Deep Neural Network Library (DNNL)...

For those wondering about the current performance of desktop Linux distributions against Microsoft Windows 10 with the latest updates as we embark upon fall update season, here is a look at the performance of eight different Linux distributions compared to Windows 10. While a larger set of cross-platform tests are currently being worked on, for this article we are focusing on different "creator" workloads from video/audio encoding, render workloads, and related software prior to the larger comparison in the next week or two.

The Blender 2.81 release cycle has entered its "bcon2" development phase of development with the focus shifting to bug fixing and stabilizing new features with now being past the initial window of merging in the big ticket items...

As was anticipated, PostgreSQL 12.0 is now officially available...

If you are a user of AMD Radeon RX 5700 "Navi" graphics and don't mind riding Mesa Git, the latest 19.3-devel code as of yesterday has several more GFX10 fixes/improvements...

Flatpak 1.5 is the newest pre-release for this Linux app sandboxing and distribution tech...

The lossy ASTC texture compression algorithm has been widely adopted in recent years with it being official extensions to both OpenGL and OpenGL ES. While it may not be as messy as the S3TC patent situation of the past, it turns out Arm's license on Adaptive Scalable Texture Compression actually is quite restrictive outside of the context of Khronos' APIs...

While initially queued as a work-in-progress feature for Linux 5.5, AMD has now submitted a batch of "fixes" to the current Linux 5.4 cycle that include enabling of the LRU bulk moves performance-boosting functionality...

Igalia is working on supporting OpenGL ES' GLSL marking of variables as "mediump" when the precision involving those variables can be lowered to half-float 16-bit registers. That in turn can help with performance when honoring that precision marking, which to date Mesa has ignored...

One of the contributions Google is working on for the upstream Linux kernel is a new "sanitizer". Over the years Google has worked on AddressSanitizer for finding memory corruption bugs, UndefinedBehaviorSanitizer for undefined behavior within code, and other sanitizers. The Linux kernel has been exposed to this as well as other open-source projects while their newest sanitizer is KCSAN and focused as a Kernel Concurrency Sanitizer...

Here is our recap of the most popular content on Phoronix for Q3. This is also the first time any one vendor has nearly dominated the charts thanks to multiple successful product launches and growing embrace for Linux/open-source...

The Linux kernel will begin doing a basic sanity check of x86_64 CPUs with the RdRand instruction to see if it's at least returning "random looking" data otherwise warn the user at boot time. This stems from a recent issue where AMD's RdRand behavior with some hardware (particularly, buggy motherboards) could have borked RdRand issues...

Samba 4.11 was just released a few weeks back with big scalability improvements, but looking ahead to Samba 4.12 will be some big performance improvements for those leveraging encryption...

Given the recent AMD "ABBA" Ryzen 3000 boost fix, the upcoming release of Ubuntu 19.10 powered by Linux 5.3, here is a fresh round of AMD Ryzen 9 3900X vs. Intel Core i9 9900K benchmarks in a side-by-side matchup . It's just not any comparison but our largest i9-9900K vs. 3900X comparison ever: 112 gaming benchmarks and 321 system/CPU benchmarks carried out for our most extensive look yet at how these ~$500 CPUs are competing in this fierce race.

Tomorrow is when PostgreSQL 12.0 should meet the world for this popular open-source SQL database server...

At last month's GNU Tools Cauldron was an update on the Radeon GCN back-end state for the GCC compiler, which is likely to see more code land around year's end...

One of the benefits of upgrading to Ubuntu Server 19.10 this month is for a newer version of PHP7 providing new features and better performance. While that took close to one year to land PHP 7.3 in Ubuntu 19.10, it looks like next spring's Ubuntu 20.04 LTS will be pulling in PHP 7.4 that is shipping later this year...

While there hasn't been too much to write on it in recent weeks, the Panfrost Gallium3D driver within Mesa for Arm Midgard/Bifrost graphics continues chugging along. The latest work on it is switching over to a new scheduler for Midgard...

Last week we began our belated NVIDIA GeForce RTX SUPER benchmarking by looking at the RTX 2060 / 2070 / 2080 SUPER Linux gaming performance in a 26-way graphics card comparison. For those more interested in the RTX SUPER graphics cards for their OpenCL compute performance potential, these benchmarks today are for you.

While announced some months ago, today in-step with the OSPray 2.0 Alpha ray-tracing release is the inaugural development release of the Open Volume Kernel Library (OpenVKL)...

Intel open-source engineers have sent out their initial patches wiring up USB 4.0 support for the Linux kernel...

Sadly not making it for the just-closed Linux 5.4 merge window but hopefully something we could see in Linux 5.5 is recent patches on "frequency invariance" in optimizing the Schedutil frequency scaling governor that will really benefit Intel CPUs and improve their performance by double digits...

As a minor update following last month's Phoronix Test Suite 9.0 release, version 9.0.1 is now available and also for all PTS users are a number of new/updated test profiles via OpenBenchmarking.org...

It was another busy September on Phoronix with 298 original Linux/open-source news articles and 22 featured articles / hardware reviews written by your's truly. There was an interesting combination of both hardware and software happenings over the past month, so here is your convenient recap...

Over a year ago the AMD APU support in the Radeon Open Compute (ROCm) stack was quietly removed and has yet to be re-enabled in the upstream ROCm packages. But should you be wanting to use ROCm for their compute APIs or OpenCL on APUs, unofficial Ubuntu packages are now available to provide this capability...
