Abstract:
1. A method, in a data processing system, for informing a process of an access to a pre-allocated memory region/memory window (MR/MW) of the data processing system, comprising: receiving, in a channel adapter, a Remote Direct Memory Access (RDMA) message for accessing a MR/MW of the data processing system identified by an identifier of the MR/MW included in the RDMA message; processing the RDMA message in the channel adapter to write data associated with the RDMA message to the MR/MW identified by the identifier; automatically notifying a process associated with the MR/MW of the write of data to the MR/MW in response to the writing of the data to the MR/MW; and processing, by the process, the data in the MR/MW in response to the notification, wherein automatically notifying the process associated with the MR/MW of the write of data to the MR/MW comprises posting an event queue element (EQE) to an event queue (EQ).
