My device is ZYNQ7000 and I run petalinux on it.
In vivado, I use IP core "concat" to connect the hardware irq to arm, and the GIC irq number is 63. Now I want to request an irq in petalinux by the function "request_irq", but what the irq number is, or how can I now the irq number?

you can directly use the irq number mentioned for your IP in device tree(petalinux path: images/linux/system.dtb)
convert system.dtb into system.dts using below command.
dtc -I dtb -O dts -o system.dts system.dtb
you can check in system.dts file.

Thank you for reply!
But in my project, this interrupt is just a normal output port connected to the GIC. There is no message about it in device tree. I just know the GIC number is 63(because the pl gic number is added from 61). So what should I do to solve this problem?
