  • Proton 3.7 Updated, More RADV Fixes To Help Steam Play Gaming

    Overnight Valve promoted their Proton 3.7-7 build with better alt-tab handling and full-screen behavior for many games. There is also fixed mouse behavior and DXVK 0.80 is now used for the Direct3D-11-over-Vulkan translation to yield better Steam Play gaming performance.

    Steam Play 3.7-8 is also now available in beta with minor compatibility fixes, which Valve says is in preparation for future Proton versions.

  • AMD Stages A Number Of Fixes Ahead Of Linux 4.20~5.0 - Plus Vega 20 "MGPU Fan Boost"

    Following several interesting and exciting feature pull requests for the next Linux kernel (to be released as either version 4.20 or 5.0), AMD developers have moved onto stabilizing this massive amount of new feature code.

    The first "fixes" pull request was submitted today to DRM-Next focusing on stabilizing and fixing issues stemming from all this new code. As a reminder, that feature code ranges from AMD Picasso APU support along with Raven 2, a lot of Vega 20 enablement code including compute support, initial xGMI support, VCN dynamic power gating, DC display code enhancements, VCN JPEG engine support, Raven Ridge GFXOFF support, GPUVM virtual memory performance improvements, and a variety of other interesting work.

  • NVIDIA's Guide For Getting Started With RTX Ray-Tracing In Vulkan

    Last month's Vulkan 1.1.85 release brought NVIDIA's experimental ray-tracing extension (VK_NVX_raytracing) while for those curious how this fits into the Vulkan workflow, NVIDIA today published a guide for getting started with ray-time ray-tracing in the Vulkan space.

  • Freedesktop.org: its past and its future

    At the 2018 X.Org Developers Conference (XDC) in A Coruña, Spain, Daniel Stone gave an update on the status of freedesktop.org, which serves multiple projects as a hosting site for code, mailing lists, specifications, and more. As its name would imply, it started out with a focus on free desktops and cross-desktop interoperability, but it lost that focus—along with its focus in general—along the way. He recapped the journey of fd.o (as it is often known) and unveiled some idea of where it may be headed in the future.

    The talk was billed with Keith Packard as co-presenter, but Packard could not make it to XDC; Stone said that he sent Packard a copy of the slides and heard no complaints, so he left Packard on the slide deck [PDF]. Stone wanted to start with the history of fd.o, because there are lots of new contributors these days—"which is great"—who may not know about it.

Opening Files with Qt on Android

After addressing Android support in KF5Notifications another fairly generic task that so far required Android specific code is next: opening files. Due to the security isolation of apps and the way the native “file dialog” works on Android this is quite different from other platforms, which makes application code a bit ugly. This can be fixed in Qt though. Read more

Ubuntu-Centric Full Circle Magazine and Debian on the Raspberryscape

  • Full Circle Magazine: Full Circle Weekly News #121
  • Debian on the Raspberryscape: Great news!
    I already mentioned here having adopted and updated the Raspberry Pi 3 Debian Buster Unofficial Preview image generation project. As you might know, the hardware differences between the three families are quite deep ? The original Raspberry Pi (models A and B), as well as the Zero and Zero W, are ARMv6 (which, in Debian-speak, belong to the armel architecture, a.k.a. EABI / Embedded ABI). Raspberry Pi 2 is an ARMv7 (so, we call it armhf or ARM hard-float, as it does support floating point instructions). Finally, the Raspberry Pi 3 is an ARMv8-A (in Debian it corresponds to the ARM64 architecture). [...] As for the little guy, the Zero that sits atop them, I only have to upload a new version of raspberry3-firmware built also for armel. I will add to it the needed devicetree files. I have to check with the release-team members if it would be possible to rename the package to simply raspberry-firmware (as it's no longer v3-specific). Why is this relevant? Well, the Raspberry Pi is by far the most popular ARM machine ever. It is a board people love playing with. It is the base for many, many, many projects. And now, finally, it can run with straight Debian! And, of course, if you don't trust me providing clean images, you can prepare them by yourself, trusting the same distribution you have come to trust and love over the years.

OSS: SVT-AV1, LibreOffice, FSF and Software Freedom Conservancy

  • SVT-AV1 Already Seeing Nice Performance Improvements Since Open-Sourcing
    It was just a few weeks ago that Intel open-sourced the SVT-AV1 project as a CPU-based AV1 video encoder. In the short time since publishing it, there's already been some significant performance improvements.  Since the start of the month, SVT-AV1 has added multi-threaded CDEF search, more AVX optimizations, and other improvements to this fast evolving AV1 encoder. With having updated the test profile against the latest state as of today, here's a quick look at the performance of this Intel open-source AV1 video encoder.

  • What I learned during my internship with the FSF tech team
    Hello everyone, I am Hrishikesh, and this is my follow-up blog post concluding my experiences and the work I did during my 3.5 month remote internship with the FSF. During my internship, I worked with the tech team to research and propose replacements for their network monitoring infrastructure. A few things did not go quite as planned, but a lot of good things that I did not plan happened along the way. For example, I planned to work on GNU LibreJS, but never could find enough time for it. On the other hand, I gained a lot of system administration experience by reading IRC conversations, and by working on my project. I even got to have a brief conversation with RMS! My mentors, Ian, Andrew, and Ruben, were extremely helpful and understanding throughout my internship. As someone who previously had not worked with a team, I learned a lot about teamwork. Aside from IRC, we interacted weekly in a conference call via phone, and used the FSF's Etherpad instance for live collaborative editing, to take notes. The first two months were mostly spent studying the FSF's existing Nagios- and Munin-based monitoring and alert system, to understand how it works. The tech team provided two VMs for experimenting with Prometheus and Nagios, which I used throughout the internship. During this time, I also spent a lot of time reading about licenses, and other posts about free software published by the FSF.
