62 * Do not advance a vcpu's time beyond the correct delivery time for
63 * interrupts that have been missed due to preemption. Deliver missed
64 * interrupts when the vcpu is rescheduled and advance the vcpu's virtual
65 * time stepwise for each one.
66 * no_delay_for_missed_ticks:
67 * As above, missed interrupts are delivered, but guest time always tracks
68 * wallclock (i.e., real) time while doing so.
69 * no_missed_ticks_pending:
70 * No missed interrupts are held pending. Instead, to ensure ticks are
71 * delivered at some non-zero rate, if we detect missed ticks then the
72 * internal tick alarm is not disabled if the VCPU is preempted during the
73 * next tick period.
74 * one_missed_tick_pending:
75 * Missed interrupts are collapsed together and delivered as one 'late tick'.
76 * Guest time always tracks wallclock (i.e., real) time.
