We need a entry address and boot up code AP. For that purpose, I reuse VCPUOP_initialise and VCPUOP_up hypercall. The former guest set the entry address of AP, the later one boot up them. For this, I add some code in arch_set_info_guest() to initialize the AP(mostly what we did after INIT-SIPI-SIPI sequence), that's what I means here... -- regards Yang, Sheng _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
