[dpdk-dev] [PATCH v7 00/12] Clean up pci uio implementations

[Tetsuya Mukawa <mukawa@igel.co.jp>]

Currently Linux implementation and BSD implementation have almost same
code about pci uio. This patch series cleans up it.

PATCH v7 changes:
 - Add below patches. Also, the order of patches are changed.
   - eal: Add pci_uio_alloc_resource()
   - eal: Add pci_uio_map_resource_by_index()
   - eal: Consolidate pci_map and mapped_pci_resource of linuxapp and bsdapp
   - eal: Consolidate pci_map/unmap_resource() of linuxapp and bsdapp
   - eal: Consolidate pci uio functions of linuxapp and bsdapp
   - eal: Consolidate pci_map/unmap_device() of linuxapp and bsdapp
   - eal: Consolidate rte_eal_pci_probe/close_one_driver() of linuxapp and bsdapp
   (Thanks to Bruce Richardson)
 - While adding above, below patches are not changed at all.
   - eal: Fix coding style of eal_pci.c and eal_pci_uio.c
   - eal: Close file descriptor of uio configuration
   - eal: Fix memory leaks and needless increment of pci_map_addr
   - eal/bsdapp: Change names of pci related data structure
   - eal: Fix uio mapping differences between linuxapp and bsdapp
 - some function names are changed like below.
   - pci_uio_alloc_uio_resource() to pci_uio_alloc_resource().
   - pci_uio_map_uio_resource_by_index() to pci_uio_map_resource_by_index().
   (Thanks to Iremonger, Bernard)

PATCH v6 changes:
 - Free mapped resources in pci_uio_map_resource().
 - Fix error handling in pci_uio_map_resource().
   (Thanks to David, Marchand)

PATCH v5 changes:
 - Rebase to latest master branch.

PATCH v4 changes:
 - Rebase to latest master branch.
 - Fix bug in pci_uio_map_resource() of BSD code. 'maps[i].path' shouldn't be freed.
     Fixed in below patch:
     [PATCH 3/5] eal: Fix memory leaks and needless increment of pci_map_addr
 - 'path' member of 'struct mapped_pci_resource' should not be removed because it will be used in BSD code.
     Fixed in below patch:
     [PATCH 5/5] eal: Fix uio mapping differences between linuxapp and bsdapp

PATCH v3 changes:
 - Squash patches related with pci_map_resource().
 - Free maps[].path to easy to understand.
   (Thanks to Iremonger, Bernard)
 - Close fds opened in this function.
 - Remove unused path variable from mapped_pci_resource structure.

PATCH v2 changes:
 - Move 'if-condition' to later patch series.
 - Fix memory leaks of path.
 - Fix typos.
   (Thanks to David Marchand)
 - Fix commit title and body.
 - Fix pci_map_resource() to handle MAP_FAILED.
   (Thanks to Iremonger, Bernard)

Changes:
 - This patch set is derived from below.
   "[PATCH v2] eal: Port Hotplug support for BSD"
 - Set cfg_fd as -1, when cfg_fd is closed.
   (Thanks to Iremonger, Bernard)
 - Remove needless coding style fixings.
 - Fix coding style of if-else condition.
   (Thanks to Richardson, Bruce)
