Hi
I'm newbe in xen developing. I must perform an access to a process
address space that run in a VM from dom0. I have a virtual address, so I
must know a paging mode enabled (from cr0 and cr4) and I must acces to
page table of current process via cr3. You can suggest me some examples
that perform this task? I see that exist some function like
map_domain_va() and similar but I must verify the proper name in xen
3.1. You can help me?
TNX in advance.
Best Regards

I think the functions in xc_ptrace.c that you've already found are probably
along the right lines for you. map_domain_va sounds like it should do what
you want. There are probably other functions in there you'll find useful
too!
Cheers,
Mark
