Abstract
A method includes recording a user-level interrupt as undeliverable in a mailbox at least partially based on an interrupt domain identifier and an interrupt recipient identifier included in a user-level interrupt message associated with the user-level interrupt. The recording is at least partially based on an indication that the user-level interrupt is undeliverable to a recipient application thread executing on a processor core of a plurality of processor cores in a multi-core system.
