INTERRUPT HANDLING FOR RECEIVED NETWORK PACKETS
Abstract: embodiments herein describe techniques for providing interrupts from a shared network adapter to a host operating system or control program. a register can store an interrupt state of the host that indicates whether an interrupt is required. for example, the host may still be busy processed previous received data (e.g., a packet received from a network), which means no interrupt is required. when the host has processed each of the requests from the shared network adapter, the interrupt state in the register can be changed that if any additional data is received, an interrupt is required. moreover, the register can include a bitmask to indicate which of a plurality of receive data queues has data ready for the host to process.
