Hello all,
this may be a stupid question, but...
It seems to me that address spaces and activities (to avoid the words "task" and "thread") are othogal concepts. What is the reason for L4 to not keep them seperate in it's API ? (i.e. there is task_new to create an activity _and_ an address space and there is lthread_ex_regs to create an activity in an already existing address space). It would seem a lot "cleaner" to me if there was one system call to create an address space (without any activity in it) and another one to create an activity, specifying as a parameter the address space in which it will execute. Is there a reason (perhaps security ?) why it wasn't done like that in L4 ?
Thanks for any insights.
Rob
