For AVMM, you can use rxm_irq_<n> signals for interrupt request. What do you mean customize PCIe interrupt? Any difference with the standard one?

Thanks @SK,

​

My scenario is: when Arria10 received one wireless frame (data) of 1ms from the air attenna, I need trigger an (event) interrupt to notify x86 Host by using PCIe bus, that's what I mean " customize PCIe interrupt".

​

in your opinion, is there any Arria10 refrence design for this ？ ​
