Web18 jun. 2024 · In the monolithic system, the service is obtained by a single system call, which requires two mode switches (changes of the processor’s ring or CPU mode). In the microkernel-based system, the service is obtained by sending an IPC message to a server, and obtaining the result in another IPC message from the server.

WebStarting from the IPC implementation in L4/Alpha, we also implemented a lower-level communication prim-itive, similar to Exokernel’s protected control trans-fer [12], to ﬁnd out whether and to what extent the L4 IPC abstraction can be outperformed by a lower-level primitive.
