hurd-l4 VM server

[Maurizio Boriani]

Hi,
        first of all I'd like to tell that Marcus' idea of root server 
usage/desin for hurd on L4 and may be others subsys is a really great and 
flexible solution. 
        So as you could had read on l4ka list I'm working on a VM server 
(which I've thinked for HURD but may be used by other subsystems).

That are main ideas I'm implementing/porting:
        * VM server based on UVM 
        * I'm near to finish (I think/hope :) ) reimplementation of pmap.c 
                where substituded i386 direct MMU pages requests with sigma0 
                ipc pages request.
        * I'm starting with main writing in order to start it user-space
        * I'm thinking (and this is my question) which interface VM server 
                should have in order to be contacted and used from other HURD 
                (and others) servers. Should I "simply" code an IDL interface
                mapping it 1-1 with uvm_extern.h or you can suggest something
                better?

Thanks,
baux

P.S. For Marcus, what do you think about?
