[Xen-devel] check if a page is modified



Hi,
How can I check if a page is dirty or not in xen source code?
I am debugging the hvm_hap_nested_page_fault function in hvm.c and want to see when a page  fault occurs, see what is written on
the page.
Does the page_mark_dirty makes a page dirty or not?

Regards,
