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 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 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.
