Abstract
A method of providing fast and efficient kernel functions including those usually performed by kernel daemons and other kernel processes such as those which service interrupts. The method consists of using minimal-context processes that carry only the system-related information needed to do the work they are created to do. Compared to the full-context processes presently used to do kernel functions, minimal-context processes are created quickly and switch economically. If associated with a work queue, the minimal-context process performs a series of tasks within a single active session. If no queue is used, a minimal-context process can wake up and accomplish a single task rapidly. The method generally relates to kernel-based operating systems.
