  • Fedora Linux 34 available for download

    Woo-hoo! Today is officially the day many of us have been waiting for. Yes, Fedora Linux 34 is finally available for download. For many Linux users, Fedora is considered the best overall operating system to be based on that open source kernel. The distro focuses on truly free and open source software -- a pure Linux experience. It is also fairly bleeding edge, but at the same time, it remains stable for everyday use.

    What makes Fedora 34 so exciting? Well, this version of the Linux-based operating system uses GNOME 40 as its default desktop environment, and version 40 is the most electrifying version of GNOME in years. GNOME 40 is notable for a horizontal workspace switcher and having the Dash (favorites launcher) moved to the bottom of the screen. Despite being released last week, Ubuntu 21.04 fails to comes with this version of GNOME.

  • Red Hat boss on Linus Torvalds: 'He's changed the world' | ZDNet

    Red Hat CEO Paul Cormier has continued his regional virtual tour this week, sharing with media in the Asia Pacific region on Thursday his thoughts on what the work Linus Torvalds has done over the last 30 years means for the world.

    "Oh, my gosh, where do you start?," he began.

    "I mean, he's changed the world. Just his vision of an open operating system."

    It's not just the operating system that came out of it, Cormier said.

    "That was the very beginning. Even when we got started with Linux 20-plus years ago, it really wasn't -- it was for hobbyists, but what Linus did was really show the world that open was a better way to develop new innovation," the CEO said. "And I think where Red Hat took it from there, from an enterprise perspective, we showed the world that we really could run critical enterprise workloads on open source-developed software."

  • DRM Driver Posted For AI Processing Unit - Initially Focused On Mediatek SoCs - Phoronix

    BayLibre developer Alexandre Bailon has posted a "request for comments" of a new open-source Direct Rendering Manager (DRM) driver for AI Processing Unit (APU) functionality. Initially the driver is catering to Mediatek SoCs with an AI co-processor but this DRM "APU" driver could be adapted to other hardware too. Alexandre Bailon sums up this DRM AI Processing Unit driver as "a DRM driver that implements communication between the CPU and an APU. This uses VirtIO buffer to exchange messages. For the data, we allocate a GEM object and map it using IOMMU to make it available to the APU. The driver is relatively generic, and should work with any SoC implementing hardware accelerator for AI if they use support remoteproc and VirtIO."
