  • Acer Chromebook 13 and Chromebook Spin 13 Will Support Linux Apps on Day One

    Acer's recently announced Chromebook 13 and Chromebook Spin 13 appear to be the first Chromebooks to ship with support for Linux apps out-of-the-box at launch.

    Google already announced that it worked on implementing support for Linux apps on Chrome OS during the Google I/O conference last month, and the first Chromebook to run Linux apps is Google's Pixelbook, as expected, and the functionality was later discovered to be available on the Samsung Chromebook Plus as well.

  • Locks in the classroom – 2018

    For the sixth year now, our grade nine students have been doing 3D modeling using Blender. We ran late this year, but the final locks were finished a couple of weeks ago, and they’re finally ready for publishing.

  • CVE-2018-3665: Lazy State Save/Restore As The Latest CPU Speculative Execution Issue

    The latest speculative execution vulnerability affecting modern CPUs has now been made public: Lazy State Save/Restore, a.k.a. CVE-2018-3665.

    This vulnerability concerns saving/restore state when switching between applications. The newly-disclosed vulnerability exploits lazy-state restores for floating-point state when context switching, which is done as a performance optimization, to obtain information about the activity of other applications on the system.

  • AI Is Coming to Edge Computing Devices

    Very few non-server systems run software that could be called machine learning (ML) and artificial intelligence (AI). Yet, server-class “AI on the Edge” applications are coming to embedded devices, and Arm intends to fight with Intel and AMD over every last one of them.

  • Cortex-A76, Mali-G76, and ML chip designs pump up AI

    Arm’s Cortex-A76 design offers speed/efficiency improvements including a 4x boost in AI performance, and is paired with a new Mali-G76 GPU that is also said to aid AI. Meanwhile, Arm revealed more details on its upcoming ML co-processors.

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.
