[dpdk-dev] [PATCH v13 0/7] rte_bus_pci

[Gaetan Rivet]

I have rebased the work done by Shreyansh and Thomas to follow
the bus abstraction introduced in v17.02 for the PCI bus
implementation.
This series is only a partial version of the previous one, because
some of the patches have already been integrated, and others still
need rework.

Additionally, Jan Blunck sent this RFC:

[RFC] eal: use busname and devargs to attach devices

That has not been considered for this version as it had not yet spawned
a discussion.

changes in v13:
  - Removed the PCI tests. They cannot follow the bus implementation
    anymore, and it is an opportunity to update their original design.
  - Changed the rte_pci_match function semantic to match its name.
  - Made the rte_pci_match function private.
  - Made the rte_bus_list private
  - Made rte_eal_pci_add_device,
         rte_eal_pci_insert_device,
         rte_eal_pci_remove_device,
     functions private.

Additional work is needed:
  - The PCI bus should be moved to the relevant bus sub-directory.
  - The documentation must be updated.

But this version should allow for the PCI bus implementation to be
integrated in v17.05-rc2.

Gaetan Rivet (1):
  test: remove pci tests

Shreyansh Jain (6):
  pci: split match and probe
  pci: remove loop over drivers in device detach
  pci: add bus driver
  pci: use bus driver for scan/probe
  pci: use bus driver for attach/detach
  doc: remove deprecation notice for rte_bus
