• Wayland's Weston 6.0.1 Released With Build System Fixes & Other Corrections

  Weston 6.0 was released back in March with a remote/streaming plug-in and Meson becoming the preferred build system among other improvements. Weston 6.0.1 was released today by Simon Ser with various fixes to this reference Wayland compositor.

  Weston 6.0.1 is mostly made up of Meson build system fixes/improvements to ensure a good Meson experience. There is also a fix for building with pre-4.4 kernels and a variety of other smaller fixes.

• OpenStack Stein feature highlights: vGPU support coming in Red Hat OpenStack Platform 15

  Red Hat is working on the next release of the supported enterprise distribution of OpenStack, Red Hat OpenStack Platform 15, based on the Stein community release. In this multi-part blog series, we’ll be examining some of the features that Red Hat and the open source community have collaborated on–starting with a look to future workloads, such as artificial intelligence.

  "How does OpenStack enable next generation workloads?" you ask. When it comes to computer-driven decision making, machine learning algorithms can provide adaptable services that can get better over time. Some of these workloads, such as facial recognition, require GPUs to ingest and process graphical data in real time. But the more powerful GPUs often used for machine learning and such are expensive, power-hungry, and can take up a lot of room in the servers' chassis. When working with GPUs at scale, optimized utilization is key to more cost effective machine learning.

• Panfrost Gallium3D Picks Up Yet More Features Thanks To Collabora's Summer Internship

  Just a few days ago I wrote how the Panfrost Gallium3D driver continues making incredible progress for this community-driven, open-source graphics driver targeting Arm Bifrost/Midgard graphics. There's yet another batch of new features and improvements to talk about.

  Most of this feature work continues to be done by Panfrost lead developer Alyssa Rosenzweig who is interning at Collabora this summer and appears to be spending most of her time working on this reverse-engineered Arm graphics driver supporting their recent generations of IP.

• Vulkan 1.1.112 Released While Open-Source ANV + RADV Drivers Continue Marching Along

  Vulkan 1.1.112 was outed this morning as the newest documentation update to this high performance graphics and compute API.

  Vulkan 1.1.112 is quite a mundane update with just documentation corrections and clarifications this go around and not any new extensions. But at least the clarifications should help out some and other maintenance items addressed by this Vulkan 1.1.112 release. It's not a surprise the release is so small considering Vulkan 1.1.111 was issued just two weeks ago.

• 'Bulls%^t! Complete bull$h*t!' Reset the clock on the last time woke Linus Torvalds exploded at a Linux kernel dev

  Linux kernel chieftain Linus Torvalds owes the swear jar a few quid this week, although by his standards this most recent rant of his is relatively restrained.

  Over on the kernel development mailing list, in a long and involved thread about the functionality and efficiency of operating system page caches, firebrand-turned-woke Torvalds described Aussie programmer Dave Chinner’s arguments in the debate as "bullshit," "complete bullshit," and "obviously garbage."

  To be fair to the open-source overlord, this is a far less personal attack than previous outbursts, such as the time he slammed "some security people" as "just f#cking morons," or that unforgettable straight-to-the-point detonation: "Mauro, SHUT THE F**K UP."

• It Looks Like PulseAudio 13.0 Will Be Releasing Soon

  It's been a year since the release of PulseAudio 12 and even eleven months since the last point release but it looks like the next PulseAudio release will be out very soon.

  The next PulseAudio release has been under discussion with the sorting out of when the release will take place and any blocker bugs. As it stands now, there is just one blocker bug remaining and that is addressing a regression.

• A One Line Kernel Patch Appears To Solve The Recent Linux + Steam Networking Regression

  As a follow-up to the issue reported on Friday regarding the latest Linux kernel releases causing problems for Valve's Steam client, a fix appears pending that with changing around one line of code does appear to address the regression.

  Linus Torvalds got involved and pointed out a brand new kernel patch that may solve the issue. That patch was quickly reaffirmed by Linux gamers as well as prominent Valve Linux developer Pierre-Loup A. Griffais.

• Mesa 19.1.1 Is Coming Next Week With A Variety Of Fixes

  Debuting two weeks ago was the Mesa 19.1 quarterly feature update while due out early next week is the first bug-fix point release.

  Mesa 19.1 is a huge update over 19.0 and earlier. Mesa 19.1 brought multiple new Gallium3D drivers as well as a new Vulkan driver (TURNIP), performance optimizations, new Vulkan extensions, mature Icelake support, and a variety of other features as listed in the aforelinked article.

With the Linux 5.2 kernel a few weeks out from its stable release and now being in the middle of the Mesa 19.2 development cycle for the RADV Vulkan and RadeonSI OpenGL drivers, here are some fresh results looking at the latest open-source AMD Radeon Linux graphics driver stack compared to the latest NVIDIA proprietary graphics driver. In this article the focus is on the mid-range (Polaris) line-up against the NVIDIA competition while similar tests on the high-end are currently being carried out.

These mid-range Linux GPU gaming benchmarks are intended to provide some fresh figures with the current open-source RadeonSI/RADV performance compared to NVIDIA. Beyond the upcoming high-end tests, next month of course is the Radeon RX 5700 series launch where we'll be providing launch-day Linux benchmarks. The mid-range cards tested for today's comparison included the Radeon RX 560, RX 570, RX 580, and RX 590. On the NVIDIA side was the GeForce GTX 1060, GTX 1650, GTX 1660, and GTX 1660 Ti.

• Google's Graphics API Debugger 1.6 Adds Stadia Support

  Google's GAPID, also known as the Graphics API Debugger, continues serving as an interesting open-source and cross-platform Vulkan debugger. On Thursday version 1.6 of GAPID was released.

  The GAPID 1.6 release adds Stadia support so developers working on porting their games to run on Google's cloud gaming service can use GAPID for debugging any Vulkan problems.

• Intel Graphics Driver Ready For HDR Support In Linux 5.3, Other Last-Minute Features

  While there still is a few weeks until the Linux 5.2 kernel will debut and thus the opening of the Linux 5.3 merge window, due to DRM-Next halting new feature code from merging prior to that point, in preparation Intel open-source developers sent in their final batch of feature work aiming for Linux 5.3.

  Intel developers already had sent in multiple feature updates for 5.3 while Wednesday was their last scheduled update.

• RadeonSI Gets Some Tidying Ahead Of Navi/GFX10 Support (Radeon RX 5700 Series)

  Well known open-source AMD developer Marek Olšák sent out a set of eight RadeonSI Gallium3D patches this morning that appear mostly mundane and namely come down to some minor code alterations. This work though is in stepping towards the actual Navi/GFX10 support we expect to be dropped incredibly soon.

  The eight patches alone aren't anything to get excited about just prep work. At least the eighth patch for renaming/re-documenting cache flush flags does make mention of changes with the GFX10 hardware.
