Real-Time Base Technology Accepted in Mainline Linux Kernel.TimeSys Contributes to Mainline mainline Drug slang verb To inject a drug Linux Kernel The nucleus of the Linux operating system. The Linux kernel, which was developed by Linus Torvalds, was integrated with software from the GNU Project and other sources to create the actual Linux operating system. See Linux, GNU/Linux and kernel. Support for Real-Time Technology; Announces Real-Time Extensions Now Standard in LinuxLink Subscription PITTSBURGH -- Basic support for real-time Linux features is now available in the 2.6.18 kernel and will be further extended in future kernel versions. Core technologies related to real-time performance accepted for inclusion into the mainline Linux kernel source have resulted from the leadership of open source contributors such as Red Hat's Ingo Molnar and TimeSys Senior Open Source Developer Thomas Gleixner. These key technologies submitted by developers at companies such as TimeSys, Red Hat and others are being permanently merged by Linus Torvalds Linus Benedict Torvalds (born December 28 1969 in Helsinki, Finland) is a Finnish software engineer best known for initiating the development of the Linux kernel. into the mainline Linux kernel. This marks a significant shift from the traditional approach of having individual kernel developers maintain different real-time patch sets outside of the mainline tree. "I am pleased that we can simplify development for real-time embedded Inserted into. See embedded system. devices by bringing this technology into the mainline kernel," said Gleixner. Additional real-time features, currently available as kernel patches, will continue to be merged into subsequent kernels, increasing the open source availability of core real-time capabilities and associated infrastructure in the Linux kernel. In a related announcement, the LinuxLink by TimeSys developer service has been expanded to provide all LinuxLink subscribers with access to these real-time patches. A LinuxLink subscription is a web-based service that provides tools, open source code, detailed technical reference information, and other embedded development resources for helping software engineers to customize Linux for their devices. LinuxLink subscribers will realize the value of continuous updates as real-time enhancements continue to be merged into the mainline kernel, with support for more features and architectures. In addition to the latest technology, subscribers have access to expert resources for help and advice on integrating and tuning real-time capabilities for their unique hardware platforms Each hardware platform, or CPU family, has a unique machine language. All software presented to the computer for execution must be in the binary coded machine language of that CPU. Following is a list of the major hardware platforms in existence today. See platform. . "The inclusion of real-time capabilities in the kernel validates the work of TimeSys in this space," said Larry Weidman, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of TimeSys. "Our customers that require real-time capabilities can be confident that they are on a path that has a clear future, not only with TimeSys, but with the broader Linux community. TimeSys continues to be a leader in real-time who contributes back to the open source community and, by making the real-time extensions available to all LinuxLink customers, we hope to make a supported real-time solution affordable to a wider audience." Real-Time performance enhancements available in the 2.6.18 kernel include priority inheritance (parallel) priority inheritance - A technique for avoiding priority inversion by temporarily raising the prioriry of all processes that want to access a shared resource to the highest priority level of any of them. support to prevent priority inversions (parallel) priority inversion - The state of a concurrent system where a high priority task is waiting for a low priority task which is waiting for a medium priority task. The system may become unstable and crash under these circumstances. , and extensions to the generic interrupt handling layer across all architectures, including established embedded architectures such as ARM. These features are key infrastructure components that enable predictable and consistent performance in Linux, as required for real-time applications. Customers subscribed to LinuxLink have a solution that is based directly on the same real-time technology in the 2.6.18 kernel release, the real-time preemption preemption U.S. policy that allowed the first settlers, or squatters, on public land to buy the land they had improved. Since improved land, coveted by speculators, was often priced too high for squatters to buy at auction, temporary preemptive laws allowed them to acquire patch, and additional real-time enhancements that are in the process of being merged into the mainline Linux kernel. The LinuxLink developer service is aligned with the forward-moving direction of the open source Linux community, rather than locking developers into propriety pro·pri·e·ty n. pl. pro·pri·e·ties 1.
