Hello, <br><br> I have two questions about Lguest I'd like to ask:<br><br>1) I'm trying to add support for 3 level paging (for PAE) to lguest. When the guest wants to set_pte_at() or set_pmd() , the host just releases the shadow versions of these guys, and demand_page will do the rest. But for releasing the right entries, this functions use some information like the top level page table.
<br><br>I don't know how to implement the PAE version of guest_set_pmd. I guess I should follow the release_pmd technic, but I'd need some extra information. Should I use the release_all_pagetables, like the set_pte() case ??
<br><br><br>2) I need to invoke some hypercall and send a 64bit value but I don't have two 32bit argument "slots" available. Is it a good idea to use lguest_data for transferring the 64bit value ? <br><br>thank you in advance
