Each IPC request +to a server temporarily maps the server's address space etc. into the calling +functions address space, except for the callstack. Callstack should be a bunch +of 4K pages, so they can easily be mapped to be unreachable by deeper nested +server calls, whereas the normal stack can be mapped to higher order pages to +save a little bit of memory access latency when the client is operating +normally. |
