Abstract

A method includes receiving a first interrupt request from a first device instance of a plurality of device instances. The first interrupt request is requesting an interrupt of a processor. The method also includes updating a bit vector based on the first interrupt request. The bit vector comprises a plurality of bits representing an accumulation of interrupt requests. The method further includes generating a gang interrupt comprising the updated bit vector. The method also includes transmitting the gang interrupt to call a first device driver associated with the first interrupt request based on the bits in the bit vector.
