Hi, VMX maintainers, I was looking at the nested EPT code while following up on Ed's email about altp2m design, and I can't see where nested-EPT entries get removed when a host EPT entry is removed/changed.
On nested NPT, this is handled in hap_write_p2m_entry(), which detects that the domain has nested p2ms and calls p2m_flush_nestedp2m() if necessary. But nested EPT doesn't use the ->write_p2m_entry() hook to update entries, it uses atomic_write_ept_entry() instead. AFAICS the only flushing done on that path is ept_sync_domain(), which doesn't do anything about nested p2ms. Am I forgetting something? Cheers, Tim. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
