There are two types of chores that execute in the supervisor supervisor-promoted chores SPChores are created as a result of a user chore entering the OS via a call to a supervisor library routine, and execute within the users address space supervisor daemons SvDaemons exist independently of any particular user task, and execute within the OS domain on each processor. SPChores execute on behalf of the user to fulfill a particular request for system services, whereas SvDaemons provide assistance for system-wide services such as networking and file systems. The runtime model for SPChores has been defined elsewhere. This document presents a design for the SvDaemon runtime model and interface. This is a preliminary design, and subject to change.
