[dpdk-dev] [PATCH v11 00/13] rte_bus + rte_pci_bus

[Thomas Monjalon]

I've continued the work done by Shreyansh for bus abstraction
and PCI implementation.
This change has two benefits:
  - ease future introduction of new bus
  - clean existing buses (only PCI here)
The same kind of work must be done on VDEV in order to move
these implementations as bus drivers.

changes in v11:
- fixes for BSD
- remove useless bus object retrieving
- remove useless bus reference in rte_device
- some rewording and patch reordering

Unfortunately, it is not ready to be integrated in 17.02.
More specifically:
  - the tests need some review/rework
  - the PCI implementation requires more work
  - the documentation must be updated

However there are some new buses waiting for the bus abstraction,
which is simple and good enough.
That's why I have isolated the generic bus model in first patches
and will apply them in 17.02-rc1. It will allow to base new buses
on top of rte_bus.


Shreyansh Jain (13):
  bus: introduce bus abstraction
  bus: add scanning
  bus: add probing
  app/test: check bus registration
  app/test: check bus scan
  app/test: check bus probe
  pci: split match and probe
  pci: remove loop over drivers in device detach
  pci: add bus driver
  app/test: add PCI bus driver
  pci: use bus driver for scan/probe
  pci: use bus driver for attach/detach
  doc: remove deprecation notice for rte_bus
