Subject: [dpdk-dev] Question regarding PMDs
Date: Wed, 31 Jul 2013 14:23:40 -0700	[thread overview]
Message-ID: <1486472B-BF17-4A85-887A-806E6DB32480@mahan.org> (raw)

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
