Simple data transfer over PCIe for co-processing

I will briefly explain what I am trying do. I have a host PC running linux and connected to an Arria GX II over PCIe. I am trying to send some data over to the FPGA, do some processing on that ( say ...

Hi ,

gpushkar

1. There are no other Linux driver's for that design. You have to write your own kernel module. What do you mean by simple data transfer ? You can modify this driver, and test read / write speed from BAR's for example.

2. DMA test failed. FPGA couldn't read and write from host PC mem. Host PC is 32 bit?

Igor

1. By simple data transfer I mean being able to either use the FPGA as a mapped memory ( already doing this) or stream data to the FPGA ( to do some DSP filtering for example)

2. Yes, Host PC is 32 bit.
