RE: [Xen-devel] Need information related to shadowing

["Sameer Ahuja" <sameer.ahuja@xxxxxxxxxxx>]

Hi,

Thanks a lot to all of you for your previous replies. That helped me a
lot in understanding the code. I still have some queries.

Can you please tell me how is Shadow Page Table generated/maintained?
What is the flow for the page fault handler of VMM in context of x86_64
(Intel EM64T)?

If possible, please tell me the code flow related to shadow page table
handling in XEN.

I have gone through the links you sent earlier as well as some of the
code files especially through following:

xen\arch\x86\mm\shadow\multi.c
xen\arch\x86\mm\shadow\common.c
xen\arch\x86\mm\mm.c

But I have not been able to establish the code flow based on Intel
EM64T.
Regards,
Sameer

Although the website seems to be down right now, the student project
here: http://www.cs.aau.dk/library/cgi-bin/detail.cgi?id=1136884892
actually has a pretty good explanation of xen memory management.  It
will get you started before looking at the code at least.
