This PCIE_PWR_STATE_PULSE interrupt is generated to let the software know of the power management events.The PCIE_PWR_STATE_PULSE interrupt is generated by aggregating the POWER_STATE_CHANGE_INTERRUPT and DPA_INTERRUPT outputs of the PCIe core.
In EP mode, software can check the PCIE_USER_LINKSTATUS[23-16] POWER_STATE_CHANGE_FUNCTION_NUM bit field to determine the physical function for which power state change occurred.
The PCIE_USER_PMCMD[2] POWER_STATE_CHANGE_ACK bit can be used to acknowledge the POWER_STATE_CHANGE_INTERRUPT.
