Microkernel Design: Interprocess Communication • Communication between processes or threads in a microkernel OS is via messages. • A message includes: – A header that identifies the sending and receiving process and – A body that contains direct data, a pointer to a block of data, or some control information about the process.
Microkernal Design: I/O and interrupt management • Within a microkernel it is possible to handle hardware interrupts as messages and to include I/O ports in address spaces. – a particular user-level process is assigned to – a particular user-level process is assigned to the interrupt and the kernel maintains the mapping.
