Hi @oska874,

 

Yes, RPU can send the Interrupt to the APU using IPI (inter processor interrupts).

Here we have an  IPI example for the PMU and RPU. 

http://www.wiki.xilinx.com/Zynq+UltraScale+Plus+MPSoC+-+IPI+Messaging+Example

 

Also Please check the "IPI Interrupts and Message Buffers section" in Zynq MP TRM (ug1085).

 

Best Regards,
Srikanth

RPU has seperate GIC interface to handle RPU peripheral interrupts.
