use struct sched_object as the main interface of scheduling, then make scheduler as an independent module to vcpu: - add struct sched_object as one field in struct vcpu - define sched_object.thread for switch_to thread - define sched_object.prepare_switch_out/in for prepare_switch before switch_to - move context_switch_out/context_switch_in into vcpu.c as vcpu.sched_obj.prepare_switch_out/in - make default_idle as global idle.thread for idle_thread - make vcpu_thread as vcpu.sched_obj.thread for each vcpu thread - simplify switch_to based on sched_object Tracked-On: #1842 Signed-off-by: Jason Chen CJ <jason.cj.chen@intel.com> Acked-by: Eddie Dong <edide.dong@intel.com>
