Acces a VM process address space from dom0.

Acces a VM process address space from dom0.

[Paradox]

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!
