hi, all:

Now, i want to get the information of configuration of physcial memory within the whole physical node.

by refering to some open literature, i focus on some data-structures as follows:

Frame Table, namely, "struct page_info * frame_table";
Machine-to-physical translation table (M2P), which i have not found the definitive structure of it.

my questions is whether the frame_table and M2P table covers all the physical memory (RAM) or not.

in addition, i have found a interface to userspace application running in domain0. the interface is:

XEN_DOMCTLl_getpageframeinfo, and XEN_DOMCTL_getpageframeinfo2

and my question is whether i can get the information of configuration of physcial memory within the whole physical node, or only get the information within a specific domain. furthermore, maybe i can only get the information of inuse page of frame_table, is right?

if anyone can help me, thanks in advance.
