  • Keith Packard Plumbs Direct Display Extensions Into RADV & ANV

    As part of his ongoing contract work for improving virtual reality head-mounted display (VR HMD) support on the Linux desktop, now that his DRM leasing and other X.Org Server / kernel level work is getting in order, Keith Packard sent out a set of patches implementing direct display extensions for Mesa's Radeon RADV and Intel ANV Vulkan drivers.

  • Gallium3D Now Supports NIR Shader Disk Cache

    With the Gallium3D OpenGL on-disk shader cache most notably used right now by the RadeonSI driver, TGSI is the intermediate representation currently being cached to the disk for speeding up game load times, etc. Given the RadeonSI NIR back-end continuing to mature, Timothy Arceri of Valve has added NIR caching support.

  • LunarG's Vulkan SDK 1.0.68 Released

    LunarG today has begun shipping an updated version of their SDK based against the upstream and current Vulkan 1.0.68 specification.

  • Core i9 7980XE vs. Threadripper 1950X On Linux 4.15 With Ubuntu 18.04

    With more than one hundred different benchmarks, here are some fresh tests of the Core i9 7980XE and Ryzen Threadripper 1950X boxes when running on the Linux 4.15.2 stable kernel atop a daily snapshot of Ubuntu 18.04 LTS.

    For those curious about how the CPU performance is on Linux 4.15 following the Spectre and Meltdown mitigation work, in the days ahead will be a larger CPU comparison using the latest kernel release. For those wondering about the Linux 4.15 + Ubuntu 18.04 performance for high-end desktop platforms, I ran a larger comparison of tests just on the Core i9 7980XE and Threadripper 1950X systems.

Happy birthday, GNOME: 8 reasons to love this Linux desktop

GNOME has been my favorite desktop environment for quite some time. While I always make it a point to check out other environments from time to time, there are some aspects of the GNOME desktop that are hard to live without. While there are many great desktop environments out there, GNOME feels like home to me. Here are some of the features I enjoy most about GNOME. Read more

Amiga Enthusiast Gets Quake Running On Killer NIC PowerPC CPU Core

The Amiga community remains one of the most passionate and inventive we have ever seen, even now, decades after Commodore’s demise. A couple of weeks back, we featured just a few recent projects that were designed to breathe new life into aging Amiga systems, or at the very least ensure they remain repairable for the foreseeable future. Our article explaining how to build a cheap Amiga emulator using a Raspberry Pi was immensely popular as well. Today, however, we stumbled across a video that encapsulates the ingenuity of many of the more technical folks in the Amiga community. What it shows is an Amiga 3000UX, equipped with a Voodoo 3 card and BigFoot Networks Killer NIC M1, running some software – including Quake – on the Killer NIC’s on-board Power PC processor.

New Devices With Defective Intel Chips and Linux Support

  • Linux-friendly embedded computer runs on Apollo Lake power
    Axiomtek has released a rugged, Ubuntu-ready “eBOX627-312-FL” embedded PC with a dual-core Celeron N3350, 2x GbE, 6x USB, and 4x serial ports plus mini-PCIe, HDMI, SATA, and “Flexible I/O.”
  • EPIC board boasts 4x GbE ports and PCIe x4
    Aaeon is rolling out a new EPIC form-factor “EPIC-KBS9” SBC with 6th or 7th Gen Core S-series chips, 4x GbE ports, up to 32GB DDR3, and mini-PCIe and PCIe x4 expansion. Aaeon’s EPIC-KBS9 follows two other EPIC-KBS SBCs to support Intel’s 6th “Skylake” or 7th “Kaby Lake” generation S-Series processors: the EPIC-KBS7, which emphasized real-world ports, and last month’s EPIC-KBS8, which is a bit more feature rich but with fewer coastline ports. Unlike these earlier models, the KBS9 offers 4x GbE ports, up to 32GB DDR4-2133, and a full-size PCIe x4 slot, which supports NVMe storage.
