  • 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.

SUSE/OpenSUSE: Conference and More

  • IDG study “Cloud Native 2022”: Where do European companies stand in their digital transformation? [Ed: IDG as corporate propaganda platform, hardly even hiding it anymore]

    The modernisation of IT infrastructure is picking up speed, but most companies still see a lot of room for improvement in their digital transformation. This is the conclusion of a recent study conducted by IDG Research Services in collaboration with SUSE. Even if in some cases the extent of implementation differs significantly, the companies surveyed from Germany, France and the UK agree on one point: the time to deploy cloud-native technologies is now.

  • The Evolution of Linux: a success story from Fujitsu and SUSE | SUSE Communities [Ed: Revisionism that omits GNU]

    Technological innovations are often considered to be ideas and solutions that take off immediately. But the evolution of Linux tells a different story: From humble beginnings in the 1990s, Linux has grown slowly and steadily to become a leading operating system in the business world, and now a business-critical operating system to run SAP. During this time, Fujitsu and SUSE have continued to innovate together, helping businesses everywhere to realize the benefits of Linux by running their SAP applications on it. I caught up with Jürgen Ellwanger and Martin Werner at the Global Fujitsu SAP Competence Centre to find out more about how Fujitsu and SUSE supported the evolution of Linux through a partnership of collaboration and innovation.

Intel: Intel Alder Support in Linux

  • Alder Lake system features DDR5, six GbE ports, and 20Gbps USB 3.2 Gen2X2

    Neousys unveiled two embedded PCs based on Intel’s 12th Gen S-series with up to 64GB DDR5-4800: The “Nuvo-9000” has up to 6x GbE with optional PoE+, 5x USB 3.2 Gen2 (including a 2×2 port), M.2 with PCIe Gen4, and up to 2x PCIe x16. There is also a smaller, fanless “Nuvo-9531.” Neousys has announced two of the first embedded computers based on Intel’s 7nm 12th Gen Alder Lake processors. Both the PCIe x16 equipped Nuvo-9000 and more compact Nuvo-9531 use the high-end Alder Lake S-series processors.

  • Intel Alder Lake N Support Introduced For Mesa 22.0 - Phoronix

    In addition to this week seeing Raptor Lake S support added for Mesa 22.0, the Alder Lake N additions have also been merged for this quarter's Mesa update. Given the insignificant changes from the driver perspective for the existing Alder Lake (S) support, the Alder Lake N support is namely just adding new PCI IDs and identifying them as Alder Lake family while having "Display13" for the display capabilities.

  • Intel releases patch for Alder Lake's Thread Director Linux support to increase performance and energy efficiency

    With the release of Intel's 12th Gen Core Alder Lake series of CPUs, it was discovered that performance for the new CPUs was more efficient in Microsoft Windows 11 than in the Linux operating system. This is due to Linux not having adequate support for Intel's Thread Director technology that allows for the operating system to access high-performing Golden Cove cores and the energy-efficient Gracemont cores properly. Intel's Thread Director is created from the Enhanced Hardware Feedback Interface or HFI.
