On entry to VMXAssist: 1) %edx is the processor number, i.e. vcpu id, and for BSP it's 0. 2) %ebx is the vector number from SIPI. Also removed some ugly tailing space. This looks fine for SMP bootstrap, but will current vmxassist support multiple CPUs concurrently in vmxassisted real mode? I wonder if a lot of global state needs to be made per-cpu to support that. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
