  • Intel AMX Support Appears Ready For Linux 5.16 - Phoronix

    It's been over one year since Intel disclosed Advanced Matrix Extensions and began posting patches for bringing up AMX support under Linux in anticipation of Xeon Scalable "Sapphire Rapids" processors. While the compiler-side work to GCC and LLVM/Clang has been landing, finally with the forthcoming Linux 5.16 cycle that AMX support appears ready for landing.

    Merged today to tip/tip.git's "x86/fpu" branch where kernel FPU changes are queued ahead of the next merge window, the last of the AMX enablement patches were queued up. Most notably, the work for actually enabling the AMX feature and being able to expose it to user-space via the new interface.

  • BLK-MQ Support For OpenZFS Pending As Latest Performance Optimization

    A new pull request is pending for implementing multi-queue block (blk-mq) support within OpenZFS' Zvol code, which can lead to sizable performance benefits.

    Tony Hutter opened up the pull request at the end of last week for blk-mq support. Utilizing blk-mq allows for queuing and submitting I/O requests to block devices simultaneously. With modern multi-core CPUs and speedy storage devices, BLK-MQ can lead to very real benefits.

  • AMDGPU DP 2.0 MST Support Sent In For DRM-Next - Phoronix

    AMDGPU changes already queued up in DRM-Next for Linux 5.16 brought initial code for DisplayPort 2.0 ahead of next-gen GPUs with this connectivity support. Sent out today as a separate pull request is wiring up the DisplayPort 2.0 Multi-Stream Transport (MST) capability for the AMDGPU kernel driver.

    Sent in as a late topic branch is the AMDGPU DP 2.0 MST support along with a necessary change to the DRM common DisplayPort MST helper code. Multi-Stream Transport allows for multiple independent displays to be driven from a single DisplayPort output, AMDGPU has supported DP MST for DisplayPort 1.x, but additional changes are needed for DP 2.0 compatibility.

Ubuntu: Internet of Things (IoT), CyberDog, ZeroDown, and OVS (Open vSwitch)

  • Ubuntu Blog: Embedded systems: the advent of the Internet of Things – Part II

    This is the second part of the two-part blog series covering embedded Linux systems and the challenges brought about by the proliferation of Internet of Things (IoT) devices. In Part I, we surveyed the embedded ecosystem and the role Linux plays within that space. This blog takes you on the next step in the journey, where we explore the most demanding challenges facing manufacturers of tightly embedded IoT devices.

  • CyberDog: a four legged robot revolution with Ubuntu

    Late this year, Chinese tech giant Xiaomi unveiled CyberDog: a quadrupedal, experimental, open-source robot that the firm claims will improve the robot development environment and promote the development of the robot industry. Today, Canonical dives into the specifications of this four legged robot and discover how Ubuntu is helping the device become an open source technological platform. Xiaomi has a clear vision for its product. As Huang Changjiang, PM at Xiaomi, explains, “CyberDog is developers’ technological partner from the future. It equips inhouse-made high-performance servo motors, high computing ability, with built-in AI for visual detection system and voice interaction system, supporting a variety of bionic motion gestures.”

  • ZeroDown® Software Targets Open Source with New Canonical Partnership

    As businesses around the world and in every major industry define and accelerate their cloud strategies, the lack of open, flexible and complete high availability has become a major concern. The ZeroDown platform, built upon Canonical’s industry-leading operating system, Ubuntu, aims at integrating into Canonical’s broader Charmed OpenStack platform with its ZeroDown Ultra High-Availability TM Software, eliminating downtime and data loss for its customers, running seamlessly through planned or unplanned downtime events.

  • Data centre networking: what is OVS? | Ubuntu

    In one of our preceding blogs, we spoke about Software-Defined Networking (SDN) and the key drivers behind it. Virtualisation is one of the fundamental aspects that characterises SDN, and has influenced the architecture of network switching in the data centre. OVS (Open vSwitch) is a fundamental component of modern and open data centre SDNs, where it aggregates all the virtual machines at the server hypervisor layer. It represents the ingress point for all the traffic exiting VMs, and can be used to forward traffic between multiple virtual network functions in the form of service chains. Let’s take a closer look in order to understand what OVS is.
