  • OpenChrome KMS Can Now Do Runtime Resolution Changes, Hopes To Go Mainline In 2018

    The OpenChrome KMS/DRM driver can finally handle run-time resolution changes without crashing. The developer now hopes to be able to mainline this driver into the Linux kernel in 2018.

    OpenChrome KMS previously has been unable to handle run-time resolution changes without crashing the X.Org Server, but now this kernel mode-setting driver can do so. After previously battling a standby resume problem for OpenChrome KMS and now tackling this screen resolution change crash, developer Kevin Brace is now able to get by without regular crashes to his computer. This now puts the OpenChrome KMS support about on-par with the DDX driver's user-space mode-setting support.

  • OpenChrome DRM Driver To Work On New GEM/TTM Code, Regression Fixes

    Now that the OpenChrome DRM driver is hoping to go mainline in 2018 now that it can handle run-time resolution changes without crashing the X.Org Server, the project's lone developer Kevin Brace has published a TODO list of other code changes he has planned prior to getting this open-source VIA x86 graphics driver into the mainline Linux kernel.

  • David Airlie Moves Toward Upstreaming Soft FP64 Support In Mesa

    There's been work going on for years of "soft" FP64 support to allow emulated support for the double-precision floating-point data types for GPUs not otherwise inherently supporting this capability. The soft support would allow for some older GPUs to then advertise OpenGL 4.0+ support now that ARB_gpu_shader_fp64 support could be enabled. That day looks like it's finally coming for mainline Mesa.

  • Vulkan WSI Support Is The Latest Being Worked On For Wine

    Following more Wine Vulkan code being merged and the first milestone being achieved of vulkaninfo working, Roderick Colenbrander has submitted his latest patches in the bring-up of Vulkan support under Wine.

  • This Cryptocoin Miner Uses GPU Heat To Warm Up Your Room

    Now, a French startup Qarnot has added way new name to the list: a crypto heater. Yes, you heard that right. The heater, called QC1, can warm up your room while its mines crypto coins. To do so, it houses two Sapphire Nitro + Radeon GPU RX 580 GPUs with 8GB VRAM each.

LAS 2018

  • LAS 2018
    This month I was at my second Libre Application Summit in Denver. A smaller event than GUADEC but personally was my favorite conference so far. One of the main goals of LAS has been to be a place for multiple platforms to discuss the desktop space and not just be a GNOME event. This year two KDE members, @aleixpol and Albert Astals Cid, who spoke about release cycle of KDE Applications, Plasma, and the history of Qt. It is always interesting to see how another project solves the same problems and where there is overlap. The elementary folks were there since this is @cassidyjames home turf who had a great “It’s Not Always Techincal” talk as well as a talk with @danrabbit about AppCenter which are both very important areas the GNOME Project needs to improve in. I also enjoyed meeting a few other community members such as @Philip-Scott and talk about their use of elementary’s platform.
  • Developer Center Initiative – Meeting Summary 21st September
    Since last blog post there’s been two Developer Center meetings held in coordination with LAS GNOME Sunday the 9th September and again Friday the 21st September. Unfortunately I couldn’t attend the LAS GNOME meeting, but I’ll cover the general progress made here.

The "Chinese EPYC" Hygon Dhyana CPU Support Still Getting Squared Away For Linux

Back in June is when the Linux kernel patches appeared for the Hygon Dhyana, the new x86 processors based on AMD Zen/EPYC technology licensed by Chengdu Haiguang IC Design Co for use in Chinese data-centers. While the patches have been out for months, they haven't reached the mainline kernel quite yet but that might change next cycle. The Hygon Dyhana Linux kernel patches have gone through several revisions and the code is mostly adapting existing AMD Linux kernel code paths for Zen/EPYC to do the same on these new processors. While these initial Hygon CPUs appear to basically be re-branded EPYC CPUs, the identifiers are different as rather than AMD Family 17h, it's now Family 18h and the CPU Vendor ID is "HygonGenuine" and carries a new PCI Express device vendor ID, etc. So the different areas of the kernel from CPUFreq to KVM/Xen virtualization to Spectre V2 mitigations had to be updated for the correct behavior.

Good Support For Wayland Remote Desktop Handling On Track For KDE Plasma 5.15

The KDE Plasma 5.15 release due out next year will likely be in good shape for Wayland remote desktop handling. The KDE Plasma/KWin developers have been pursuing Wayland remote desktop support along a similar route to the GNOME Shell camp by making use of PipeWire and the XDG-Desktop-Portal. Bits are already in place for KDE Plasma 5.13 and the upcoming 5.14 release, but for the 5.15 release is now where it sounds like the support may be in good shape for end-users. Read more

Linux developers threaten to pull “kill switch”

Linux powers the internet, the Android in your pocket, and perhaps even some of your household appliances. A controversy over politics is now seeing some of its developers threatening to withdraw the license to all of their code, potentially destroying or making the whole Linux kernel unusable for a very long time.
