Detailed Description

Virtual address-space management.

The central purpose of the region-map API is to provide means to manage the virtual memory address space of an L4 task. A region-map object implements two protocols. The first protocol is the kernel page-fault protocol, to resolve page faults for threads running in an L4 task. The second protocol is the region-map protocol itself, that allows to attach a data-space object to a region of the virtual address space.

There are two basic concepts provided by a region-map abstraction:
