[Xen-devel] check if a page is modified

2016-08-20 Thread sepanta s
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,
