Kernel Log - Coming in 3.7 (Part 4): Drivers

Filed under

The developers of the Nouveau driver have made major changes to the kernel-related part of the open source driver for NVIDIA graphics cores (1, 2, 3, 4, 5, 6 and others). It should now fit better to NVIDIA's chips, which the developers have gotten to know much better through reverse engineering over the years. The overall goal is a clean, simpler driver architecture that makes it easier to implement new features such as support for NVIDIA's Scalable Link Interface (SLI), which is not yet supported in Nouveau. Another addition to Linux 3.7 is rudimentary support for setting up fan management for graphics cores from the NV40 and NV50 series, which are used in series 6xxx through 300 of GeForce cards. For some of the GeForce 600 graphics cards with a Kepler GPU (NVE0), the Nouveau driver now uses its own firmware, although it doesn't yet support any acceleration features.

The code for configuring display outputs will be more robust and flexible thanks to major changes to the i915 Intel graphics driver.

7 tools for analyzing performance in Linux with bcc/BPF

A new technology has arrived in Linux that can provide sysadmins and developers with a large number of new tools and dashboards for performance analysis and troubleshooting. It's called the enhanced Berkeley Packet Filter (eBPF, or just BPF), although these enhancements weren't developed in Berkeley, they operate on much more than just packets, and they do much more than just filtering. I'll discuss one way to use BPF on the Fedora and Red Hat family of Linux distributions, demonstrating on Fedora 26. BPF can run user-defined sandboxed programs in the kernel to add new custom capabilities instantly. It's like adding superpowers to Linux, on demand. Examples of what you can use it for include: Read more

Why the open source community needs a diverse supply chain

Diversity and inclusivity in the technology industry—and in open source communities more specifically—have received a lot of coverage, both on and elsewhere. One approach to the issue foregrounds arguments about concepts that are more abstract—like human decency, for example. But the "supply chain" metaphor works, too. And it can be an effective argument for championing greater inclusivity in our open organizations, especially when people dismiss arguments based on appeals to abstract concepts. Open organizations require inclusivity, which is a necessary input to get the diversity that reduces the risk in our supply chain. Read more
