PCI Express devices communicate via a logical connection called an interconnect or link.A link is a point-to-point communication channel between two PCI Express ports allowing both of them to send and receive ordinary PCI requests (configuration, I/O or memory read/write) and interrupts (INTx, MSI or MSI-X).. PCI-X added Message Signaled Interrupts, an interrupt system using writes to host-memory. In MSI-mode, the function's interrupt is not signaled by asserting an INTx line. Instead, the function performs a memory-write to a system-configured region in host-memory. ...

This doesn't work for two reasons: (1) the wake-up widget grabs the interrupt in exclusive mode, and (2) the PCI interrupt is still routed to the RC, leading to a screaming interrupt. This simply cannot work. To sort out this mess, we need to lift the confusion between the two interrupts.
