This invention generally relates to a methods and system in the field of independent programs operating within an operating system such as Linux and more particularly to computer software embodied in a computer readable medium including: an independent program for running autonomously in a native mode within an associated computer processor; an operating system program for running autonomously within an associated computer processor; a mode switcher process for switching operation from the independent program to the operating system program whereby the independent program functions as an embedded entity of the operating system; and wherein the mode switcher program switches the independent program from the operating system program whereby the independent program runs autonomously in the native mode.

System and methods for migrating independently executing program into and out of an operating system

A method and apparatus is disclosed herein for performing operating system (OS) switching. In one embodiment, the method comprising enabling a plurality of operating systems to run concurrently on a computer, wherein a first operating system in the plurality of operating systems is actively being run, the method comprising, identifying a second operating system of a plurality of operating systems that is to be active next, exchanging information between the first and second operating systems using a storage area accessible by the first and second operating systems, causing the first operating system to become inactive by performing a suspend operation; and causing the second operating system to become active by performing a resume operation to cause the second operating system to resume operation, wherein the information controls which operations are performed as part of one or both of the suspend and resume operations.
