Subject: [dpdk-dev] [PATCH 0/9] rte_bus parse API
Date: Wed, 24 May 2017 17:12:32 +0200 [thread overview]
Message-ID: <cover.1495629122.git.gaetan.rivet@6wind.com> (raw)
Following the evolutions announced in [1], here is the first part of
the rte_devargs rework planned for 17.08. The rationale has been partially
explained in [2].
This first part covers the introduction of the necessary facilities in
rte_bus to allow for generic device parsing. This API is implemented for
the virtual and PCI buses. Additionally, this rte_bus evolution is being
used within rte_devargs to characterize a device type by its bus.
This work is the first of two parts to reduce the dependency of the EAL
upon specific bus implementations.
Two public functions are added to rte_bus to help bus recognition:
- rte_bus_from_name
- rte_bus_from_dev
These functions are made public because the bus handle within devargs
becomes the generic device type. Recognizing device types is useful for
buses and PMDs alike.
The modified rte_devargs parsing allows declaring on the EAL command line
explicit buses to handle a device. The format is as follow:
--vdev="virtual:net_ring0" --vdev="net_tap0,iface=tap0"
-w PCI:00:02.0 -w 00:03.0
This explicit bus designation is optional; no evolution is currently
forced on users to migrate to this new format. The separating character is
arbitrary and can be any character illegal within a bus name.
Subsequently, what is allowed within a bus name has been formally
defined and is now enforced.

This patchset depends on:
bus: attach / detach API
