src/sys/rump/include/rump: rump.h
Log Message:
Add proof-of-concept code for enabling system calls to rump virtual
kernels running in other processes on the same machine or on an
entirely different host. I wrote this a while ago and am now
committing it mainly to avoid losing it. It works, but could do
with a little tuning here and there.
What this will hopefully eventually buy us is the ability to use
standard userland tools to configure rump kernels, e.g. ifconfig(8)
and route(8) could be used to configure the networking stack provided
by a rump kernel. Also some distributed OS implications may apply.
fun fact: a system call which just does copyin/copyout takes >1000x
longer when made over the LAN as compared to when made on the same
machine.
