Explain the program linkage requirements that must be met if a server is to be dynamically loaded into the kernel’s address space, and how these differ from the case of executing a server at user level.
What will be an ideal response?
Portions of the kernel’s address space must be allocated for the new code and data. Symbols within the new code and data must be resolved to items in the kernel’s address space. For example, it would use the kernel’s message-handling functions.
By contrast, if the server was to execute as a separate process then it would run from a standard address in its own address space and, apart from references to shared libraries, its linked image would be self-contained.
