  • Allwinner ARM Boards With SATA See Big Speed Boost From Single Line Patch

    Right now the low-end Allwinner ARM SBC boards featuring a SATA port have been running at a measly 36~45MB/s but with changing around a single line of kernel code, that can jump to 120MB/s.

    ARM SBCs are notorious with slow I/O particularly when piggybacking off USB or just relying upon a microSD card, but for those using SATA HDD/SSD storage with Allwinner boards, that performance is about to get a whole lot better. Uenal Mutlu discovered that by changing around some bits for increasing the SATA/AHCI DMA TX/RX FIFOs, the performance can improve by multiple times for hardware relying upon the Linux kernel's AHCI_SUNXI driver.

    [...]

    For now the patch is on the kernel mailing list but hopefully will be deemed reliable enough for making it into Linux 5.3.

  • F2FS For Linux 5.2 Sees Better SMR Drive Support, Various Fixes

    While no flashy features like EXT4's case-insensitive option with Linux 5.2, the Flash-Friendly File-System (F2FS) did see a good amount of fixes and other improvements for this new kernel round.

    F2FS continues seeing more adoption particularly on Google Android devices and that has led into an uptick in fixes now that more vendors are evaluating this file-system optimized for non-rotating drives. Jaegeuk Kim sent in the F2FS changes for Linux 5.2 on Monday and it's again heavy on the fixes.

  • LF Energy Ecosystem Gains Momentum for Open Source Innovation With New Members and Projects

    LF Energy, a Linux Foundation initiative developing and sustaining open source technology innovation in the energy and electricity sectors, is rapidly growing its community with additional founding Premier member, Faraday Grid, joining RTE. New General members include IBM, OSISoft, and Recurve; while Elering AS, Energinet, Energy Foundation, École Polytechnique Fédérale de Lausanne, Fraunhofer IEE, FIWARE Foundation, Iowa State University, Monash University, National Renewable Energy Laboratory (NREL), North Carolina State University FREEDM Center, Project Haystack, Stanford University, TenneT, The Energy Coalition, University of Kassel, and Washington State University join European Network of Transmission System Operators (ENTSO-E) and Vanderbilt University as new Associate members.

Intel Tries Again To Auto Enable GuC/HuC Functionality For Their Linux Graphics Driver

Intel previously tried auto-enabling GuC and HuC functionality within their Linux kernel graphics driver but ended up reverting the support since the driver didn't gracefully handle the scenarios of missing/corrupt firmware files. The driver should now be more robust in such situations so they will try again for turning on the automatic behavior, possibly for the upcoming Linux 5.4 cycle. Intel GuC and HuC have been around since Skylake and used for graphics workload scheduling, some power management bits, and for select media capabilities. For newer hardware is also being used as part of HEVC/H.265 handling. Read more

KDE Frameworks 5.61, Applications 19.08 in FreeBSD

Recent releases were KDE Frameworks 5.61 and KDE Applications 19.08. These have both landed in the official FreeBSD ports tree, after Tobias did most of the work and I pushed the big red button. Your FreeBSD machine will need to be following current ports – not the quarterly release branches, since we don’t backport to those. All the modern bits have arrived, maintaining the KDE-FreeBSD team’s commitment to up-to-date software for the FreeBSD desktop. The one thing we’re currently lagging on is Qt 5.13. There’s a FreeBSD problem report tracking that update. Read more
