Method and system for conditional interrupts
Abstract:
A method for issuing interrupts includes a receiving communication adapter receiving a first remote directed memory access (RDMA) write with immediate, identifying a completion queue descriptor corresponding to the first RDMA write with immediate and to a receiving entity, incrementing an interrupt counter in response to the first RDMA write with immediate. The method includes storing, by the receiving communication adapter, in response to determining that the interrupt counter value is less than the interrupt threshold value, data in the first RDMA write with immediate on the receiving device without triggering an interrupt to the receiving entity. The receiving communication adapter receives a second RDMA write with immediate, and increments the interrupt counter value corresponding to the completion queue descriptor in response to the second RDMA write with immediate. The method includes triggering the interrupt to the receiving entity in response to the interrupt counter value exceeding the interrupt threshold.
