[dpdk-users] How DPDK initialize PCIe DMA engine?

[Yuan Kevin]

Dear DPDK Community members,

I am new to DPDK. After reading through the documentation and doing web search a couple of days, I am still not clear how DPDK initialize PCIe DMA engine.

As far as I know, the PCIe scan / probe / intialization is pretty standardized, but the DMA engines along with the PCIe are very different from vendor to vendor.

My question is, what's the best place to implement the DMA initilization code within the DPDK framework and how?

Could you give me an example ?

Best regards.



Thanks,


Kevin Yuan
