Okay, I wadding into the process of writing a poll-mode driver for DPDK. First question, is the use of the UIO device a requirement (outside of the need for interrupt support) since it is possible to map the PCI bars via /dev/mem?
Second question, is it expected that the NIC hardware would already have been initialized by the kernel driver for that device? Say to load microcode on an intelligent NIC? I am sure to have more when the water level gets above my head ;-) Thanks, Patrick
