In order to ensure that all the data has arrived in memory, the interrupt handler must read a register on the device which raised the interrupt.

Using MSIs avoids this problem as the interrupt-generating write cannot pass the data writes, so by the time the interrupt is raised, the driver knows that all the data has arrived in memory. |
