| D | halt-polling.txt | 1 The KVM halt polling system
4 The KVM halt polling system provides a feature within KVM whereby the latency
5 of a guest can, under some circumstances, be reduced by polling in the host
14 dependant. In the event that no wakeup source arrives during the polling
16 invoked. Thus halt polling is especially useful on workloads with very short
17 wakeup periods where the time spent halt polling is minimised and the time
20 The generic halt polling code is implemented in:
32 as the halt polling interval, is increased and decreased based on the perceived
33 effectiveness of the polling in an attempt to limit pointless polling.
44 During polling if a wakeup source is received within the halt polling interval,
