I still have some doubt when analying XEN paging mechanism of EPT.
When run into ept_handle_violation,how to find the HPA relevant to the GPA
not mapped in EPT table yet,from m2p table?
Looking forward any help,source level answer will be appreciated!

(m2p would map HPA->GPA, not GPA->HPA). The answer is, when using ept, the ept table *is* the p2m table. So there''s no such thing as a GPA->HPA mapping that is in the p2m table but not in the ept tables. -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
