  • EXT4 Patch For Statx Support

    The statx system call was added to Linux 4.11 for providing enhanced file stats. While the statx() system call is in place for Linux 4.11, not all of the file-systems yet support it.

  • TEE Subsystem Proposed For Linux 4.12 Kernel

    Linaro developers are hoping to merge the generic TEE subsystem into the Linux 4.12 kernel this spring.

    TEE is short for the Trusted Execution Environment and is a trusted OS running in a secure environment, such as TrustZone on ARM CPUs or a separate secure co-processor. We've previously covered the work on TEE for Linux and obviously not everyone is happy about "trusted" computing efforts on Linux and implementations like TEE.

  • Bcachefs Brings New On-Disk Format With Encryption, Better Multi-Device Support
  • Bcachefs - encryption, fsck, and more

    It's been far too long since the last announcement - lots of stuff has been
    happening. The biggest milestone has been all the breaking on disk format
    changes finally landing, but there's been lots of other stuff going on, too.

    On the subject of the breaking on disk format changes - there's an excellent
    chance this'll be the last breaking change, so if you're thinking about trying
    out bcachefs this is an excellent time. Also, if you have a filesystem in the
    old format, code to read your filesystem is available in the bcachefs-v0 braches
    of both linux-bcache and bcache-tools.

Baidu puts open source deep learning into smartphones

A year after it open sourced its PaddlePaddle deep learning suite, Baidu has dropped another piece of AI tech into the public domain – a project to put AI on smartphones. Mobile Deep Learning (MDL) landed at GitHub under the MIT license a day ago, along with the exhortation “Be all eagerness to see it”. MDL is a convolution-based neural network designed to fit on a mobile device. Baidu said it is suitable for applications such as recognising objects in an image using a smartphone's camera.

AMD and Linux Kernel

  • 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.
