AFAICT the 0x004xxxxx comes from TRC_PV_HYPERCALL_V2_ARG_32, which is used by __trace_hypercall, for __HYPERVISOR_mmuext_op that would be: d.op = __HYPERVISOR_mmuext_op | (0x1 << 22); Roger. _______________________________________________ Xen-devel mailing list Xenfirstname.lastname@example.org https://lists.xenproject.org/mailman/listinfo/xen-devel
