As an End Point, PCIe subsystem reports errors to root complex so that corrective action may be taken. These messages become error interrupts on the Root Complex side. In addition, the errors that are detected by the PCIe subsystem locally are also reported to software via interrupts.
Note that for several errors of the same type that are detected in close succession, the PCIe subsystem will not necessarily send as many error messages to Root Complex. It is guaranteed to send at least one such error message.
