Abstract
A nonvolatile memory controller processes a nonvolatile memory command and generates a completion status for the nonvolatile memory command. The nonvolatile memory controller transmits the completion status to a host processing unit for storage in a completion queue of the host processing unit. An interrupt manager in the nonvolatile memory controller determines the completion queue contains an unprocessed completion status and generates an interrupt message packet. The nonvolatile memory controller transmits the interrupt message packet to the host processing unit for triggering an interrupt in the host processing unit and alerting the host processing unit to the unprocessed completion status.
