Subject: [dpdk-dev] [PATCH 08/14] eal/common: introduce rte_bus_addr
Date: Mon, 4 Jan 2016 21:08:20 +0100 [thread overview]
Message-ID: <1451938106-12145-9-git-send-email-viktorin@rehivetech.com> (raw)
In-Reply-To: <1451938106-12145-1-git-send-email-viktorin@rehivetech.com>
To support a generic manipulation with devices we need to have a general
representation of the rte_*_addr which replaces the rte_pci_addr in the code.
Here we introduce the rte_bus_addr consisting of a union of various rte_*_addr
fields and the device magic to discriminate among them.
A wrapper around rte_eal_compare_pci_addr is introduced and it will be extended
while adding a new non-PCI infra.
