  • Interrupt recovery management
    Patent number: 11126575
    Abstract: An interrupt recovery manager detects that a compute instance has exited a state in which interrupts from one or more interrupt sources were not processed at the compute instance. The recovery manager identifies a source from which interrupts may have been missed by the compute instance, and causes an indication of a potential missed interrupt from that source to be delivered to the compute instance.
