Zynq-7000 - How do I know the IRQ ID# of F2P_IRQ when I connect interrupt signals from PL to PS?

I am connecting three interrupt signals from PL to PS IRQ_F2P[15:8].

The Port tab in XPS shows the IRQ bits as follows:

IRQ_F2P[2:0]

MHS setting:

PORT IRQ_F2P = GPIO_SW_IP2INTC_Irpt & LEDs_4Bits_IP2INTC_Irpt & axi_timer_0_Interrupt

Table 7-3 in TRM states:

IRQF2P[15:8] is ID#91:84.

Where can I see how the three interrupt signals are connected to IRQF2P[15:8]?

After exporting to SDK, you can check the IRQ ID# in the parameters.h file.

In this case, the interrupt signals are assigned as below:

#define XPAR_FABRIC_GPIO_SW_IP2INTC_IRPT_INTR 91

#define XPAR_FABRIC_LEDS_4BITS_IP2INTC_IRPT_INTR 90

#define XPAR_FABRIC_AXI_TIMER_0_INTERRUPT_INTR 89

The connection between PL and PS is as below.

PL PS

IRQ_F2P[0] - IRQ_F2P[15] ID#91

IRQ_F2P[1:0] - IRQ_F2P[15:14] ID#91:90

IRQ_F2P[2:0] - IRQ_F2P[15:13] ID#91:89
