How do I verify that intel DDIO technology is used

[Hz12]

Hi，

I wonder if FPGA as an I/O device can use DDIO technology? What are the requirements for drivers of the Linux operating system kernel using DDIO technology?

Hi,
the fact that an I/O device can be FPGA based, e.g. an accelerator board doesn't make the DDIO question FPGA specific, I think.

DDIO is still solely happening inside the processor.

I understand you are asking about a FPGA based GBit ethernet peer and want to setup DDIO communication with it in the processor.

Hi,

I believe DDIO used in the Quartus and Altera IP's, is taken care in the linux drivers.

you can refer the below user guide for General Purpose IO's overview.
