hi all, i am reading kvm code , the folllowing is my understanding. 1, see if guest page table is not mapped , inject fault to the guest. 2, see if gpte dirty is set ,in order to synchronize the pte dirty with spte 3, if not , see if spte it not mapped or write protection ,to handler it. i do not know whether my analysis is right . or can any body detail it ? the page fault handler processing. thanks. -- 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
