| D | halt-polling.rst | 4 The KVM halt polling system
7 The KVM halt polling system provides a feature within KVM whereby the latency
8 of a guest can, under some circumstances, be reduced by polling in the host
14 Polling provides a latency advantage in cases where the guest can be run again
17 dependent. In the event that no wakeup source arrives during the polling
19 invoked. Thus halt polling is especially useful on workloads with very short
20 wakeup periods where the time spent halt polling is minimised and the time
23 The generic halt polling code is implemented in:
