MSI uses memory writes to deliver interrupts instead of sharing interrupt request lines. This eliminates interrupt line exhaustion and interrupt sharing problems. It also allows devices to directly provide interrupt payload data to interrupt service routines. Newer extensions like MSI-X further improve performance by supporting more messages and allowi
