Kernel-Kernel communication in a shared-memory multiprocessor
1993
Concurrency Practice and Experience
Preserved Fulltext
Either approach to interkernel communication can be used in a large-scale shared-memory multiprocessor. ...
In the standard kernel organization on a bus-based multiprocessor, all processors share the code and data of the operating system; explicit synchronization is used to control access to kernel data structures ...
