Abstract
An example method of sharing message-signaled interrupt vectors in multi-processor computer systems comprises: associating an interrupt vector with a first device component, by creating a first interrupt mapping entry of an interrupt mapping table, wherein the first interrupt mapping entry references a first processor and the interrupt vector; associating the interrupt vector with a second device component, by creating a second interrupt mapping entry of the interrupt mapping table, wherein the second interrupt mapping entry references a second processor and the interrupt vector; and creating, in an interrupt descriptor table (IDT) associated with the first processor and the second processor, an interrupt descriptor for the interrupt vector.
