1. I'm using altera FPGA as PCIe end point that connected to TI's 816x EVM ARM board.
2. By using the pcie driver example provided by altera, I'm able to read and write to FPGA
through BAR.
3. However, triggering write from FPGA side into ARM memory space keep failing.

The only different I see from the kernel message from my project and others are the message below , this message doesn't show up in my system:

"altera 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16"

Did I forget to enable any interrupt stuff either inside ARM linux or FPGA side?
