ACP port under Linux

Hi, Is there any trick to using the ACP port from FPGA under Linux (3.9)? I'm setting the f2h AR & AW CACHE/PROT/USER by hand, post-qsys, but don't see any indication that the SCU cares at all...

Hi Sir, I am trying to interface a linux program to a FPGA master using the ACP port, what address do I need to use to ensure read and writes go through the ACP port?

Actually I am not familiar with using the ACP port at all, if you can give me some guide, I will appreciate it.

I configured the AXI port cache settings as you said. Any example or reference where I can find information related to it.

Thanks.
