Following discussions with Jan [1] and some cleanup I started on pci code,
here is a patchset that reworks pdev drivers registration and hotplug api.
The structures changes mentioned in [1] are still to be done, but at least,
I think we are one step closer to it.
Before this patchset, rte_driver .init semantics differed whether it
concerned a pdev or a vdev driver:
- for vdev, it actually meant that a devargs is given to the driver so
that it creates ethdev / crypto objects, so it was a probing action
- for pdev, it only registered the driver triggering no ethdev / crypto
objects
>From my pov, eal hotplug api introduced in this patchset still needs more
work so that it does not need to know about devargs. So a new devargs api
is needed.
Changes since v1:
- rebased on HEAD, new drivers should be okay
- patches have been split into smaller pieces
- RTE_INIT macro has been added, but in the end, I am not sure it is useful
- device type has been removed from ethdev, as it was used only by hotplug
- getting rid of pmd type in eal patch (patch 5 of initial series) has been
dropped for now, we can do this once vdev drivers have been converted
