Sending those fixes as separate patches as they stand on their own.
This series improves usability of the hotplug API and fixes a few issues
with existing implementations.
The hotplug API can be tested with the fail-safe PMD[1]. Its
documentation describes how to declare slaves and how to use it.
[1]: http://dpdk.org/ml/archives/dev/2017-July/070529.html
v2:
- Add a new rte_devargs function taylored for hotplug operations.
Upon device hotplug, the device is implicitly whitelisted.
This configuration should supersede any previous existing bus
configuration.
- Merge hotplug add and remove fixes as they are now tied up.
- Do not return an rte_device handle back from hotplug_add.
v3:
- Further explain
- the new rte_eal_devargs_insert function.
- the hotplug add / remove fix
- the PCI device name fix
- Add comments to pci_name_set
v4:
- Free rte_devargs after the device is being removed,
to avoid risks of buses relying on the rte_devargs during the
process.
Gaetan Rivet (8):
vdev: implement plug operation
devargs: introduce removal function
devargs: introduce insert function
eal: fix hotplug add / remove
pci: use given name as generic name
pci: fix generic driver pointer on probe error
pci: fix hotplug operations
bus: remove useless plug parameter
