Building The Linux Kernel With LLVM's Clang Yields Comparable Performance

Linux
BSD

We have covered the LLVMLinux project many times with an increasing number of developers from the x86 and ARM world being interested in building the kernel with Clang. Among the reasons for wanting to build the Linux kernel with Clang is for possible performance advantages, faster kernel compilation times when debugging the kernel, using Clang's static analysis abilities on the kernel code itself, improving the quality of LLVM and Clang by finding missing/broken compiler features, and improving the overall code quality of the Linux kernel by making the code compatible with more compilers.

Linux Foundation flings two full-time developers at OpenSSL

Filed under
Linux

The Linux Foundation's new elite tech repair team has named its initial areas of focus as it works to find and seal holes in widely-used open source software.

The Linux Foundation announced on Thursday that members of the "Core Infrastructure Initiative" (CII) will dedicate resources to working on the Network Time Protocol, OpenSSH, and OpenSSL to hunt down and fix flaws in the tech that helps tie the internet together.

"All software development requires support and funding. Open source software is no exception and warrants a level of support on par with the dominant role it plays supporting today's global information infrastructure," said Jim Zemlin, the executive director of the Linux Foundation.

Intel unveils Linux-on-Atom platform for autonomous cars

Filed under
Linux

Intel announced a Linux- and Atom-based hardware/software platform called Intel In-Vehicle Solutions for assisted driving and eventually self-driving cars.

Intel says its Internet of Things Group achieved revenue of $482 million in the first quarter, up 32 percent year-over-year, “driven by strong demand for in-vehicle infotainment (IVI) systems.” While some of that appears to be Windows-based, Linux is the chief platform going forward in its current line-up of Tizen Linux based IVI reference systems. Linux is also the platform driving the newly announced Intel In-Vehicle Solutions (IIVS), which initially combines IVI with advanced driver assistance systems (ADAS) features. IIVS will eventually migrate to semi-autonomous and autonomous vehicles, says Intel.

The Clonezilla team released a new development version for their Linux distro, but this is not a very large update and it only integrates a small number updates and changes.

“The underlying GNU/Linux operating system was upgraded. This release is based on the Debian Sid repository, as of May 27, 2014,” reads the official announcement.

Tiniest Linux COM yet?

Filed under
Linux

An open-spec COM that runs OpenWRT Linux on a MIPS-based Ralink RT5350 SoC has won its Indiegogo funding. The $20, IoT-focused “VoCore” measures 25 x 25mm.

How low can you go? Tiny computer-on-modules (COMs) for Internet of Things (IoT) applications are popping up everywhere, with recent, Linux-ready entries including Intel’s Atom or Quark-based Edison, Ingenic’s MIPS/Xburst-based Newton, Acme Systems’s ARM9/SAM9G25 based Arrietta G25, and SolidRun’s quad-core i.MX6-based MicroSOM. Now, an unnamed Chinese startup has raised over six times its $6,000 Indiegogo funding goal for what could be the smallest, cheapest Linux COM yet.

GOG.com is a digital distribution platform that is specialized mostly in old games, but the company that owns it, CD Projekt Red, wants to also extend the support to include Linux. They are now looking for people to help them with Linux ports, although it seems that some of them will be distributed in Wine wrappers.

System76 Galago UltraPro: Powerful Linux laptop but not quite an ultrabook

Reviews

When I set out to find a new laptop, I was looking for an ultrabook --a 13-inch powerhouse with plenty of battery life and a gorgeous screen. On top of everything, it had to run Linux.

That search led me to the System76 Galago UltraPro. Although not technically an ultrabook (it's too big, doesn't have ultrabook-level battery life, and doesn't contain a solid state drive). What it does have is elegance and power to spare...to the tune of besting most currently available ultrabooks. And, like all System76 devices, it runs Ubuntu Linux.

Let's take a look at what's good and bad with the Galago UltraPro.

Why No Flash Support for Linux Is Good for Open Source

Filed under
GNU
Linux
OSS

Flash, the ubiquitous media framework for the Web, soon will no longer work for Linux users of the Chromium browser, the open source version of Google Chrome. Is it time for the Linux world to panic? Not at all.

Here's what's happening: Soon, the means by which Flash support was traditionally implemented in Chromium, via a plugin originally designed for Netscape, will no longer work. Instead, Flash support will come in the form of a new API called Pepper, which Google has created for Chrome.

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 Opensource.com 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
