Hi. Can someone explain me what Sigma0 server is for? As far as I know it
serves as a pager of root task and when a page fault occurs, it maps the
page to the physical page with a same address. Am I right? If so, why
should root task request pages if it can simply access them directly?
Furthermore, I need to implement my custom pager for non-privileged tasks
(sigma0 is not accessible for them, I hope), or the root task itself (for
example, if I need a persistent virtual memory). So why should I need
Sigma0? Does it mean I can implement my own Sigma0? Thanks.
