ABSTRACT:
Described is a fast boot mechanism that generally operates by persisting static data and/or code for a system component, and then providing the system component with access to the static data and/or code during a subsequent device boot. For example, the static data and/or code of one or more components may be restored from non-volatile memory to volatile memory, whereby subsequent reboots need not have the components re-compute their persisted static data, making subsequent reboots faster. A fast boot infrastructure may include an interface set, and provides first mechanism that persists static data and/or code for a system component, and a second mechanism that provides the system component with access to the static data and/or code. The fast boot infrastructure may also provide the component with a way to invalidate static data and/or code, along with a background mechanism that collects static data and/or code from the system component.
