Linux
  • Linus Torvalds On Fun, the Linux Kernel, and the Future

    Linus Torvalds, creator of the Linux kernel, took to the stage at Open Source Summit in Los Angeles. In this keynote presentation, Torvalds joined The Linux Foundation Executive Director Jim Zemlin in conversation about Linux kernel development and how to get young open source developers involved. Here are some highlights of their talk.

  • Collabora & Linux Kernel 4.13

    Linux kernel 4.13 is out and - like in the 4.12 release - 12 Collabora developers contributed a total of 72 patches. In addition Collabora developers provided 25 Reviewed-by tags and 10 Tested-by tags. Furthermore 83 patches received a Signed-off-by tag from Collabora peoples. Again, general information about the merge window is available by LWN.net in form of the following articles: part 1 and part 2.

  • A Quick EXT4 Run With Linux 4.14 Git

    After the Linux 4.14 merge window is over, I'll begin with a lot of fresh Linux kernel benchmarks from this in-development release. But I/O and EXT4 changes already have me running some preliminary tests.

    With EXT4 are some scalability improvements to note. The scalability improvements around allocating inodes may help in some workloads. I received a report of this patch on a consumer SSD helping out the Phoronix Test Suite's BlogBench. There's also been some talk of other performance changes to find in Linux 4.14.

  • Core i9 7900X vs. Threadripper 1950X On Ubuntu 17.10, Antergos, Clear Linux

    While we have already compared the Threadripper 1950X to the current top-end Core i9 7900X processor, today we are taking things a step further with our Threadripper Linux benchmarks by doing a side-by-side showdown when each system is tested across three different Linux distributions.

    Here is a multi-way comparison when running the Threadripper 1950X and Core i9 7900X under Ubuntu 17.10 with its latest daily snapshot as of testing, Antergos 17.9 Rolling, and Clear Linux 17650. This provides a diverse look at the performance across distributions for these high-end desktop processors.

Debian GNU/Linux 9 "Stretch" Receives L1 Terminal Fault Mitigations, Update Now

According to the security advisory published on Monday, the new kernel security update addresses both CVE-2018-3620 and CVE-2018-3646 vulnerabilities, which are known as L1 Terminal Fault (L1TF) or Foreshadow. These vulnerabilities had an impact on normal systems, as well as virtualized operating systems, allowing a local attacker to expose sensitive information from the host OS or other guests. "Multiple researchers have discovered a vulnerability in the way the Intel processor designs have implemented speculative execution of instructions in combination with handling of page-faults. This flaw could allow an attacker controlling an unprivileged process to read memory from arbitrary (non-user controlled) addresses," reads today's security advisory. Read more

Rugged, sandwich-style Sitara SBC has optimized Linux stack

Forlinx’s sandwich-style, industrial temp “OK5718-C” SBC runs Linux on a “FET5718-C” module with a Cortex-A15 based TI AM5718 SoC. Other features include SATA, HDMI, MIPI-CSI, USB 3.0, CAN, and mini-PCIe. Forlinx Embedded Technology, the Chinese company behind Linux-friendly SBCs such as the TI Sitara AM3354 based OK335xS-II and The Forlinx i.MX6 SBC, has posted details on a new OK5718-C SBC. Like the OK335xS-II, it’s a Sitara based board, in this case tapping TI’s single-core, Cortex-A15 based Sitara AM5718. Like the i.MX6 SBC, it’s a sandwich-style offering, with the separately available FET5718-C module hosting the up to 1.5GHz AM5718. Read more

RISC-V and NVIDIA

  • Open-Source RISC-V-Based SoC Platform Enlists Deep Learning Accelerator
    SiFive introduces what it’s calling the first open-source RISC-V-based SoC platform for edge inference applications based on NVIDIA's Deep Learning Accelerator (NVDLA) technology. A demo shown at the Hot Chips conference consists of NVDLA running on an FPGA connected via ChipLink to SiFive's HiFive Unleashed board powered by the Freedom U540, the first Linux-capable RISC-V processor. The complete SiFive implementation is suited for intelligence at the edge, where high-performance with improved power and area profiles are crucial. SiFive's silicon design capabilities and innovative business model enables a simplified path to building custom silicon on the RISC-V architecture with NVDLA.
  • SiFive Announces First Open-Source RISC-V-Based SoC Platform With NVIDIA Deep Learning Accelerator Technology
    SiFive, the leading provider of commercial RISC-V processor IP, today announced the first open-source RISC-V-based SoC platform for edge inference applications based on NVIDIA's Deep Learning Accelerator (NVDLA) technology. The demo will be shown this week at the Hot Chips conference and consists of NVDLA running on an FPGA connected via ChipLink to SiFive's HiFive Unleashed board powered by the Freedom U540, the world's first Linux-capable RISC-V processor. The complete SiFive implementation is well suited for intelligence at the edge, where high-performance with improved power and area profiles are crucial. SiFive's silicon design capabilities and innovative business model enables a simplified path to building custom silicon on the RISC-V architecture with NVDLA.

  • NVIDIA Unveils The GeForce RTX 20 Series, Linux Benchmarks Should Be Coming
    NVIDIA CEO Jensen Huang has just announced the GeForce RTX 2080 series from his keynote ahead of Gamescom 2018 this week in Cologne, Germany.
  • NVIDIA have officially announced the GeForce RTX 2000 series of GPUs, launching September
    The GPU race continues on once again, as NVIDIA have now officially announced the GeForce RTX 2000 series of GPUs and they're launching in September. This new series will be based on their Turing architecture and their RTX platform. These new RT Cores will "enable real-time ray tracing of objects and environments with physically accurate shadows, reflections, refractions and global illumination." which sounds rather fun.
