MontaVista Software is a company that develops embedded Linux system software, development tools, and related software. Its products are made for other corporations developing embedded systems such as automotive electronics, communications equipment, mobile phones, and other electronic devices and infrastructure. MontaVista is based in Santa Clara, California and was founded in 1999 by James "Jim" Ready (formerly at Mentor Graphics and creator of Versatile Real-Time Executive (VRTX)) and others. On November 10, 2009 Cavium Networks announced that it had signed a definitive agreement to purchase MontaVista for $50 million. After Cavium got acquired by Marvell, Montavista operated as an independent entity. May 12, 2009, MontaVista announced MontaVista Linux 6 (MVL6) comprising Market Specific Distributions, MontaVista Integration Platform, Software Development Kit, MontaVista Zone Content Server, and support and services. There are several differences between MVL6 and prior MontaVista Linux products. The main ones are: Market Specific Distributions (MSD) Linux operating systems (kernel + userland) optimized for each specific semiconductor vendor's hardware. MontaVista Integration Platform based on BitBake, analogous to make, which analyzes a set of directives and then builds a task dependency tree to satisfy a user command. BitBake then executes the defined tasks to completion. MontaVista Zone Content Server accessed from behind a proxy server, or local web mirror for offline operations, to fetch software and updates. Rather than depending on a mix of public HTTP, Concurrent Versions System (CVS), Git, and Subversion servers across the Internet, there is one source for each original source and patch. MontaVista Linux (formerly named Hard Hat Linux) is a Linux distribution that has been enhanced to become a full real-time operating system. The work on real-time performance has since continued to a point where MontaVista claims to support hard real-time tasks on embedded Linux as of MontaVista Linux 4.
