The kvm_entry function does not exist in the kernel because it is arch dependant. You can use vcpu_enter_guest on x86 or kvm_arch_vcpu_ioctl_run on arm to have what you are looking for. I grepped "trace_kvm_entry" in the kernel source tree to find this information. I hope this helps, Julien _______________________________________________ lttng-dev mailing list [email protected] http://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
