I spoke to Paolo about this a while back and thought to post this as RFC while I am thinking of adding some unit tests. Background: ESX refuses to run as L1 if support for EPT execute only isn't found. I am not really sure if it uses it for anything since just advertising the bits seems to work but adding the necessary plumbing seemed like a good idea.

Thank you, Bandan! I really hope all mmu related patches can be CCed to me in case if i am too busy to watch patches in kvm mail list. :) Some points are missed in this patchset: 1) You also need to tech is_present_gpte() about this fact. 2) update_permission_bitmask() need to be fixed as it always expects that read-access is available (actually, read-access is equal with user-access if ept is shadowed). -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
