Linux: Encryption, AMDVLK and Intel DRM Driver

  • diff -u: Adding Encryption To printk()

    A patch from Dan Aloni recently came in to create the option to encrypt printk() output. This would make all dmesg information completely inaccessible to users, including hostile attackers. His idea was that the less information available to hostile users, the better.

    The problem with this, as Steven Rostedt pointed out, was that it was essentially just a way for device makers and Linux distributions to shut out users from meaningfully understanding what their systems were doing. On the other hand, Steven said, he wouldn't be opposed to including an option like that if a device maker or Linux distribution actually would find it legitimately useful.

  • AMDVLK Driver Updated With New Extension, Better Geometry Shader Support

    The AMD developers working on their official, cross-platform Vulkan driver have carried out another weekly update to their AMDVLK public source tree.

    This week the updates to the AMDVLK open-source driver are fairly interesting. First up there is now VK_EXT_external_memory_host support. Coincidentally, this week RADV also wired in this extension. EXT_external_memory_host is used for importing host allocations and host-mapped foreign device memory to become Vulkan memory objects.

  • Selectable Platform Support Proposed Again For Intel's DRM Driver

    It seems like every few years or so comes a patch series proposing to allow the Intel DRM driver to limit its platform support in the name of saving a few bytes from the kernel build. This week the latest "selectable platform support" patches are out there.

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.
