The Vendor Specific Capability signals of the PCIe core, F0_VSEC_INTERRUPT_OUT, F1_VSEC_INTERRUPT_OUT, F2_VSEC_INTERRUPT_OUT, F3_VSEC_INTERRUPT_OUT, F4_VSEC_INTERRUPT_OUT and F5_VSEC_INTERRUPT_OUT, are used to generate interrupts to the EP from the RP. F0_VSEC_INTERRUPT_OUT represents the interrupt for the EP Physical Function 0, F1_VSEC_INTERRUPT_OUT is the interrupt output for EP Physical Function 1 and so on. These signals are aggregated into the PCIE_DOWNSTREAM_PULSE interrupt to the local host.
The RP can write to the Vendor specific control registers to assert these signals at the EP and this will trigger the PCIE_DOWNSTREAM_PULSE interrupt to the EP host.
