Linux Kernel Adds Real-Time Features

Filed under
Linux

Embedded developers have long maintained real-time patch sets outside the mainline Linux kernel, but those days may be coming to an end, according to representatives of Linux developer service provider TimeSys Corp. That company announced Thursday (Oct. 12) that basic support for real-time features has been added to the mainline Linux kernel.

The new real-time features are available in the Linux 2.6.18 kernel, and will be further extended in future kernel releases. TimeSys, meanwhile, has expanded its LinuxLink developer service to include real-time Linux extensions.

Real-time performance enhancements available in the 2.6.18 kernel include priority inheritance support to prevent priority inversions, and extensions to the generic interrupt handling layer across all architectures, including embedded architectures such as ARM. Technology contributors include Ingo Molnar of Red Hat and Thomas Gleixner, senior open source developer at TimeSys. Additional real-time features that are currently available as patches will continue to be merged into subsequent kernels.

The Linux desktop-a-week review: LXDE

Over the last two weeks I’ve run nothing but LXDE as my primary Linux Desktop Environment (other than a few excursions into Android land). Been using LXDE. Been enjoying LXDE. But I have practically nothing to really say about LXDE. I feel like, after all this time, I should have something interesting to talk about. But I just plain don’t. It’s fast, blisteringly fast. And it’s damned lightweight too. After that, things get pretty boring. Read more

LG’s first SoC debuts on 5.9-inch G3 Screen phone

LG announced its first SoC, a Cortex-15 and –A7 octa-core “Nuclun” with LTE-A Cat.6 tech that debuts this week in a Korea-bound LG G3 Screen Android phone. LG Electronics has decided to follow in Samsung’s footsteps and create its own ARM system-on-chip for its mobile devices. LG, which has mostly used Qualcomm processors in the past, announced an octa-core Nuclun SoC, which will debut on a 5.9-inch, Android 4.4 based LG G3 Screen phablet that will go on sale this week in Korea.

Neptune OS 4.2 Features a Refreshing KDE Desktop

ZevenOS-Neptune 4.x branch is called "It's all about you" and it was initially made available back in June. This is the second update for the distribution and the devs have refined some of the features and have added some new packages into the mix. The system is based on KDE, but don't expect to find a regular stock version implemented. It's clear that the devs have put a lot of effort into making the DE experiences unique. Users can immediately recognize what distribution they are looking at just with a glance, and that's always a good sign. Read more

How to Get Open Source Android

Android is an astonishing commercial success, and is often touted as a Linux success. In some ways it is; Google was able to leverage Linux and free/open source software to get Android to market in record time, and to offer a feature set that quickly outstripped the old champion iOS. But it's not Linux as we know it. Most Android devices are locked-down, and we can't freely download and install whatever operating systems we want like we can with our Linux PCs, or install whatever apps we want without jailbreaking our own devices that we own. We can't set up a business to sell Google Android devices without jumping through a lot of expensive hoops (see The hidden costs of building an Android device and Secret Ties in Google's "Open" Android.) We can't even respin Google Android however we want to and redistribute it, because Google requires bundling a set of Google apps. Read more
