Open Source Contributions
MontaVista has a history of being a major contributor to the Linux kernel and the open source community. From the beginning, Jim Ready said he wanted to make it "100% pure Linux" under the GPL. The core changes to make MontaVista Linux into a real-time operating system were made by Nigel Gamble and later updated by Robert Love. Robert Love submitted the changes to the Linux kernel in 2001. The Linux 2.6 stable kernel series is the first to include similar features, such as priority-based preemption. As of 2008, MontaVista had contributed 1.2% of the Linux kernel, making it the 9th-largest corporate contributor to the Linux kernel, according to a survey by the Linux Foundation.
MontaVista has strong connections with the development of Linux under the PowerPC architecture, and hosts a development Linux kernel source tree on http://source.mvista.com/. (Closed down. Patches moved to git kernel)
MontaVista has also spun off independent open source projects based on a number of its features, including dynamic power management, high resolution POSIX timers, the pramfs file system, and the openais implementation of the SA Forum's Application Interface Specification.

Famous quotes containing the words open and/or source:
“Hail ye small sweet courtesies of life, for smooth do ye make the road of it! like grace and beauty which beget inclinations to love at first sight; ‘tis ye who open this door and let the stranger in.”
—Laurence Sterne (1713–1768)
“We are threatened with suffering from three directions: from our own body, which is doomed to decay and dissolution and which cannot even do without pain and anxiety as warning signals; from the external world, which may rage against us with overwhelming and merciless forces of destruction; and finally from our relations to other men. The suffering which comes from this last source is perhaps more painful than any other.”
—Sigmund Freud (1856–1939)
