  • AMD Promotes Navi 14 Linux Support Out Of "Experimental" + Fixes For Raven Ridge

    With the initial Navi 14 support to be found in the Linux 5.4 kernel releasing this weekend the GPU ASIC (along with Navi 12) have been marked as experimental and thus not enabled by default unless passing a special module parameter to the kernel. But now at the last minute this support has been deemed non-experimental for Navi 14.

    After the original Navi 12/14 open-source driver support was published, it was then marked as experimental. Under that experimental state, the hardware initialization only happens if amdgpu.exp_hw_support=1 is set as a parameter for the AMDGPU kernel driver.

  • mesa 19.3.0-rc4
    Hi list,
    
    I'd like to announce mesa 19.3.0-rc4 is now available. We're starting to slow
    down a bit in terms of the number of patches being backported, but there's still
    a fair number of opened bugs in the release tracker:
    https://gitlab.freedesktop.org/mesa/mesa/-/milestones/5.
    As such I'm predicting at least one more -rc will be required before the 19.3
    release, I'll update the calendar accordingly.
    
    Among the changes in this release aco dominates, with anv and freedreno no far
    behind. We've reverted an underspeced egl extension that was causing
    regressions, as well as stopped modifying Khronos headers. There's also so fixes
    to i965, core mesa, llvmpipe and st/mesa.

  • Mesa 19.3.0 Not Expected Until December - RC4 Released With ACO Fixes

    Mesa 19.3 had been expected for release next week per their original release calendar, but as we are used to seeing for these quarterly feature releases, at least one if not more weekly release candidates tend to be needed for ironing out bugs. As such, Mesa 19.3.0 is now solidly looking like at least an early December release while Mesa 19.3-RC4 shipped on Wednesday.

  • Intel Graphics Compiler Update Adds 16-Bit Atomics For Tiger Lake, Other New Features

Relive Linux history with the ROX desktop

The ROX desktop is no longer being actively developed, but its legacy resounds today, and even when it was active, it was a unique take on what a Linux desktop could be. While other desktops felt roughly similar to old Unix or Windows interfaces, ROX belongs solidly in the BeOS, AmigaOS, and RISC OS desktop camps. It focuses on drag-and-drop actions (which makes its accessibility non-optimal for some users), point-and-click actions, pop-up contextual menus, and a unique system of app directories for running local applications with no installation required.

10 tips for onboarding open source contributors

Contributors are the lifeblood of many open source projects because they enable smaller projects to grow and improve without a lot of financial support and they bring fresh perspectives to the project. That is the case at Ushahidi, a non-profit organization that is building and using software to help raise the voices of underserved, marginalized communities. Our products enable local observers to submit reports about local humanitarian crises (such as political unrest and natural disasters) using their mobile phones or the internet, while simultaneously creating a temporal and geospatial archive of events. Ushahidi always strives for openness, but it's very hard to evaluate how open your organization works from the inside. Staff and longtime contributors know too much: they are cursed by knowledge and access to the people who know how things work. While a crisis brings out the good in people who want to help, getting involved with an open source project during a crisis is complex. The maintainers are usually going through a stressful time. New requests for features are coming every day. New bugs are being reported all the time. Read more

App Highlight: Open Source Disk Partitioning Tool GParted

GParted is undoubtedly one of the best partition managers for Linux out there. The user interface is very simple and gets the job done. In some cases, you end up using GParted to fix or format your USB drive as well. I had a USB disk which I couldn’t format in Ubuntu using the “Disks” app – this is where GParted came to the rescue. So, it is a quite useful tool with a lot of good features. Let me highlight them for you. Read more
