Abstract
Systems and methods are provided for a flexible and scalable operating system achieving a fast boot. A computing system is described that includes a reserved static object memory configured to store predefined static threads, and a secure kernel configured to be executed in a fast boot mode. The secure kernel further may be configured to chain the static threads to a secure kernel thread queue stored in a secure kernel work memory, and to create temporary threads in the secure kernel work memory during the fast boot mode. The computing system may include a main kernel configured to be initialized by creating dynamic threads in a main kernel work memory during the fast boot mode. The main kernel may be configured to chain the static threads to a main kernel thread queue, and to assume control of the static threads from the secure kernel.
