Subject: [dpdk-dev] [PATCH] ethdev: support PCI domains
Date: Fri, 22 Jul 2016 11:34:10 -0400 [thread overview]
Message-ID: <1469201650-32447-1-git-send-email-okaya@codeaurora.org> (raw)
The current code is enumerating devices based on bus, device and function
pairs. This does not work well for architectures with multiple PCI
segments/domains. Multiple PCI devices will have the same BDF value but
different segment numbers (01:01:01.0 and 02:01:01.0) for instance.
Adding segment numbers to device naming so that we can uniquely identify
devices.
