Hi Adithiya,


I just try to understand what you going to do before we actually go into your question.


  1. BAR0 ( MemWr, MemRd) --- ( BFM, PTILE_EP---> Custom Logic)
  2. Similarly, we can also initiate MemWr, MemRd ( Custom Logic ---> PTILE_EP ---> BFMs Shared Memory)

>> Okay, if I understand correctly that will be the reason you using custom logic instead of build in Intel BFM right ?


  1. But in the current BFM, is there a provision to exercise Interrupt ( legacy, MSI/MSI-X)?

>> I not sure how you perform your custom logic , but theoretically you can enable these capabilities in your custom BFM instance

>> BUT ensure your custom logic generates the correct signals or memory writes as per the PCIe specification.
