  • Kontainer Korner: CNCF Welcomes CRI-O, Graduates Fluentd

    The revolving door of hosted projects within the Cloud Native Computing Foundation continued to turn this week as the organization welcomed in a new incubated project and saw one of its prized pupils walk the graduation stage.

    Coming into CNCF is the CRI-O container runtime, which is an implementation of the Kubernetes container runtime interface (CRI) that provides an integration path between Open Containers Initiative (OCI) conformant runtimes and Kubernetes kubelets. It was initially developed by Red Hat and Google under the guise of the OCI Daemon and adopted in CNCF in late 2016.

    A container runtime basically provides an API and tools that abstract low-level technical details in the container. CRI-O was developed as a “slimmer” version of regularly available container runtime options.

  • Horovod: an open-source distributed training framework by Uber for TensorFlow, Keras, PyTorch, and MXNet

    The LF Deep Learning Foundation, a community umbrella project of The Linux Foundation, announced Horovod, started by Uber in 2017, as their new project, last year in December. Uber joined Linux Foundation in November 2018 to support LF Deep Learning Foundation open source projects.

    Horovod (named after a traditional Russian dance) announced at 2018 KubeCon + CloudNativeCon North America, is an open source distributed training framework for TensorFlow, Keras, MXNet, and PyTorch. It helps improve speed, as well as scales and resource allocation in machine learning training activities. The main goal of Horovod is to simplify distributed Deep Learning and make it fast.

Graphics: Mesa 19.2's Feature Freeze and Display Stream Compression (DSC) for AMD Navi

  • Mesa 19.2's Feature Freeze / Release Candidate Process Beginning Tomorrow

    Mesa 19.2 was supposed to be branched marking its feature freeze two weeks ago on 6 August along with the issuing of the first release candidate. That milestone has yet to be crossed but should happen tomorrow. Mesa 19.2 development dragged on for the extra two weeks to allow some extra features to land. Those extra features were metrics/counters support for Intel Iris Gallium3D, CCS_E modifier support, and slice/sub-slice hashing optimizations for Intel -- a big performance win. Now that those blockers have landed, the release process is expected to get underway on Tuesday.

  • Display Stream Compression (DSC) for AMD Navi
    This patchset enables Display Stream Compression (DSC) on DP 
    connectors on Navi ASICs, both SST and DSC.
    
    8k60 and 4k144 support requires ODM combine, an AMD internal
    feature that may be a bit buggy right now.
    
    Patches 1 through 5 enable DSC for SST. Most of the work was
    already done in the Navi promotion patches; this just hooks
    it up to the atomic interface. The first two reverts are of temporary
    changes to block off DSC. The third is of a commit that was
    accidentally promoted twice. The fourth and last revert fixes a 
    potential issue with ODM combine.
    
    Patches 6 and 7 are fixes for bugs that would be exposed by 
    MST DSC. One fix is with the MST code and the other in the DSC code.
    
    Patches 8, 9, and 10 are small DRM changes required for DSC MST:
    FEC, a new bit in the standard; some export definitions; and
    a previously uninitialized variable.
    
    Patches 11 through 14 are the DSC MST policy itself. This includes
    the code for detecting and validating DSC capabilities, enabling
    DSC over a link, computing the fair DSC configurations for
    multiple DSC displays, and adding to atomic state crtcs that might 
    need reprogramming due to DSC.
    
  • AMD Posts Navi Display Stream Compression Support For Linux

    One of the kernel-side features not yet in place for AMD's newest Navi graphics processors on Linux has been Display Stream Compression support but that is being squared away with a new patch series. Fourteen patches posted today adding more than six hundred lines of code to the AMDGPU Linux kernel driver enable Display Stream Compression support for DisplayPort connectors on Navi GPUs. VESA's Display Stream Compression is for low-latency lossless compression performance for power-savings and higher resolution/refresh-rates based on bandwidth and enabling the likes of DisplayPort Multi-Stream Transport (MST) technology.

KMyMoney 5.0.6 released

The KMyMoney development team today announces the immediate availability of version 5.0.6 of its open source Personal Finance Manager. Another maintenance release is ready: KMyMoney 5.0.6 comes with some important bugfixes. As usual, problems have been reported by our users and the development team fixed some of them in the meantime. The result of this effort is the brand new KMyMoney 5.0.6 release. Despite even more testing we understand that some bugs may have slipped past our best efforts. If you find one of them, please forgive us, and be sure to report it, either to the mailing list or on bugs.kde.org. Read more
