  • Ataribox runs Linux on AMD chip and will cost at least $250

    Atari released more details about its Ataribox game console today, disclosing for the first time that the machine will run Linux on an Advanced Micro Devices processor and cost $250 to $300.

    In an exclusive interview last week with GamesBeat, Ataribox creator and general manager Feargal Mac (short for Mac Conuladh) said Atari will begin a crowdfunding campaign on Indiegogo this fall and launch the Ataribox in the spring of 2018. The Ataribox will launch with a large back catalog of the publisher’s classic games. The idea is to create a box that makes people feel nostalgic about the past, but it’s also capable of running the independent games they want to play today, like Minecraft or Terraria.

  • Linux 4.14 + ROCm Might End Up Working Out For Kaveri & Carrizo APUs

    It looks like the upstream Linux 4.14 kernel may end up playing nicely with the ROCm OpenCL compute stack, if you are on a Kaveri or Carrizo system.

    While ROCm is promising as AMD's open-source compute stack complete with OpenCL 1.2+ support, its downside is that for now not all of the necessary changes to the Linux kernel drivers, LLVM Clang compiler infrastructure, and other components are yet living in their upstream repositories. So for now it can be a bit hairy to setup ROCm compute on your own system, especially if running a distribution without official ROCm packages. AMD developers are working to get all their changes upstreamed in each of the respective sources, but it's not something that will happen overnight and given the nature of Linux kernel development, etc, is something that will still take months longer to complete.

  • Latest Linux kernel release candidate was a sticky mess

    Linus Torvalds is not noted as having the most even of tempers, but after a weekend spent scuba diving a glitch in the latest Linux kernel release candidate saw the Linux overlord merely label the mess "nasty".

    The release cycle was following its usual cadence when Torvalds announced Linux 4.14 release candidate 2, just after 5:00PM on Sunday, September 24th.

  • Linus Torvalds Announces the Second Release Candidate of Linux Kernel 4.14 LTS

    Development of the Linux 4.14 kernel series continues with the second Release Candidate (RC) milestone, which Linus Torvalds himself announces this past weekend. The update brings more updated drivers and various improvements.

    Linus Torvalds kicked off the development of Linux kernel 4.14 last week when he announced the first Release Candidate, and now the second RC is available packed full of goodies. These include updated networking, GPU, and RDMA drivers, improvements to the x86, ARM, PowerPC, PA-RISC, MIPS, and s390 hardware architectures, various core networking, filesystem, and documentation changes.

  • Microservices served on blockchain, in open source
    Cloud application marketplace company Wireline is working with open source blockchain project developer Qtum The new union is intended to provide a conduit to consuming microservices at [web] scale using blockchain at the core. As we know, microservices offer the ability to create Application Programming Interfaces (APIs) without having to manage the underlying hardware and software infrastructure. [...] The Qtum a blockchain application platform combines the functions of Bitcoin Core, an account abstraction layer allowing for multiple virtual machines and a proof-of-stake consensus protocol aimed at tackling industry-use cases. The Qtum Foundation, headquartered in Singapore, is the decision-making body that drives the project’s development.

  • NVIDIA TX2 / Tegra186 Display Support Isn't Ready For Linux 4.15
    While the Jetson TX2 has been out since this past March and it's a phenomenal ARM development board, sadly the Direct Rendering Manager (DRM) driver support for it still isn't ready with the mainline Linux kernel. Thierry Reding of NVIDIA sent in the Tegra DRM driver changes for DRM-Next that in turn is staged for Linux 4.15. Reding commented that there is prepatory work for the TX2 (Tegra186) but it's not all ready for upstream yet.
