hello:
Recently, I consider implementation heritical scheduler on top of the l4 microkernel, But we meet a problem, the Pistachio handled the interrupt in microkernel internal, In that time, I remember a project in TU-Dresden is build on top of microkernel, But it`s implementation in the old l4 interface, just like the Hazelnut that not handled the interrupt (?), The suitation is some microkernel abstract the interrupt and some microkernel not abstract the interrupt. Can we implementation a real time soft mechanism with interrupt abstracted microkernel, the real time ipc, feature as: interrupt generated then a ipc send to handler and switch to the handler at once
Neil
