[dpdk-dev] [PATCH 0/8] Add Port Hotplug support to BSD

[dpdk-dev] [PATCH 0/8] Add Port Hotplug support to BSD

[Tetsuya Mukawa]

This patch series adds port hotplug support to BSD.
Before applying, following patches should be applied.
 - [PATCH v4 1/5] eal: Fix coding style of eal_pci.c and eal_pci_uio.c
 - [PATCH v4 2/5] eal: Close file descriptor of uio configuration
 - [PATCH v4 3/5] eal: Fix memory leaks and needless increment of pci_map_addr
 - [PATCH v4 4/5] eal/bsdapp: Change names of pci related data structure
 - [PATCH v4 5/5] eal: Fix uio mapping differences between linuxapp and bsdapp

Some functions will be consolidated after applying the patches, because
these functions are implemented in both Linux and BSD code.


Tetsuya Mukawa (8):
  eal: Add pci_uio_alloc_uio_resource()
  eal: Add pci_uio_map_uio_resource_by_index()
  eal: Consolidate pci_map and mapped_pci_resource of linuxapp and
    bsdapp
  eal: Consolidate rte_eal_pci_probe/close_one_driver() of linuxapp and
    bsdapp
  eal: Consolidate pci_map/unmap_device() of linuxapp and bsdapp
  eal: Consolidate pci_map/unmap_resource() of linuxapp and bsdapp
  eal: Consolidate pci uio functions of linuxapp and bsdapp
  eal: Enable Port Hotplug as default in Linux and BSD

[dpdk-dev] [PATCH 1/8] eal: Add pci_uio_alloc_uio_resource()

[Tetsuya Mukawa]

This patch adds a new function called pci_uio_alloc_uio_resource().
The function hides how to prepare uio resource in linuxapp and bsdapp.
With the function, pci_uio_map_resource() will be more abstracted.

[dpdk-dev] [PATCH 4/8] eal: Consolidate rte_eal_pci_probe/close_one_driver() of linuxapp and bsdapp

[Tetsuya Mukawa]

This patch consolidates below functions, and implements these in common
eal code.
 - rte_eal_pci_probe_one_driver()
 - rte_eal_pci_close_one_driver()

Because pci_map_device() is only implemented in linuxapp, the patch
implements it in bsdapp too. This implemented function will be merged to
linuxapp one with later patch.

[dpdk-dev] [PATCH v2 0/8] Add Port Hotplug support to BSD

[Tetsuya Mukawa]

This patch series adds port hotplug support to BSD.
Before applying, following patches should be applied.
 - [PATCH v6 1/5] eal: Fix coding style of eal_pci.c and eal_pci_uio.c
 - [PATCH v6 2/5] eal: Close file descriptor of uio configuration
 - [PATCH v6 3/5] eal: Fix memory leaks and needless increment of pci_map_addr
 - [PATCH v6 4/5] eal/bsdapp: Change names of pci related data structure
 - [PATCH v6 5/5] eal: Fix uio mapping differences between linuxapp and bsdapp

Some functions will be consolidated after applying the patches, because
these functions are implemented in both Linux and BSD code.

PATCH v1 changes:
 - Rebase to below latest patch series.
   - [PATCH v6] Clean up pci uio implementations


Tetsuya.Mukawa (8):
  eal: Add pci_uio_alloc_uio_resource()
  eal: Add pci_uio_map_uio_resource_by_index()
  eal: Consolidate pci_map and mapped_pci_resource of linuxapp and
    bsdapp
  eal: Consolidate rte_eal_pci_probe/close_one_driver() of linuxapp and
    bsdapp
  eal: Consolidate pci_map/unmap_device() of linuxapp and bsdapp
  eal: Consolidate pci_map/unmap_resource() of linuxapp and bsdapp
  eal: Consolidate pci uio functions of linuxapp and bsdapp
  eal: Enable Port Hotplug as default in Linux and BSD

[dpdk-dev] [PATCH v2 1/8] eal: Add pci_uio_alloc_uio_resource()

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch adds a new function called pci_uio_alloc_uio_resource().
The function hides how to prepare uio resource in linuxapp and bsdapp.
With the function, pci_uio_map_resource() will be more abstracted.

[dpdk-dev] [PATCH v2 4/8] eal: Consolidate rte_eal_pci_probe/close_one_driver() of linuxapp and bsdapp

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch consolidates below functions, and implements these in common
eal code.
 - rte_eal_pci_probe_one_driver()
 - rte_eal_pci_close_one_driver()

Because pci_map_device() is only implemented in linuxapp, the patch
implements it in bsdapp too. This implemented function will be merged to
linuxapp one with later patch.

[dpdk-dev] [PATCH v2 8/8] eal: Enable Port Hotplug as default in Linux and BSD

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch removes CONFIG_RTE_LIBRTE_EAL_HOTPLUG option, and enables it
as default in both Linux and BSD.
Also, to support port hotplug, rte_eal_pci_scan() and below missing
symbols should be exported to ethdev library.
 - rte_eal_parse_devargs_str()
 - rte_eal_pci_close_one()
 - rte_eal_pci_probe_one()
 - rte_eal_pci_scan()
 - rte_eal_vdev_init()
 - rte_eal_vdev_uninit()

[dpdk-dev] [PATCH v3 0/8] Add Port Hotplug support to BSD

[Tetsuya Mukawa]

This patch series adds port hotplug support to BSD.
Before applying, following patches should be applied.
 - [PATCH v6 1/5] eal: Fix coding style of eal_pci.c and eal_pci_uio.c
 - [PATCH v6 2/5] eal: Close file descriptor of uio configuration
 - [PATCH v6 3/5] eal: Fix memory leaks and needless increment of pci_map_addr
 - [PATCH v6 4/5] eal/bsdapp: Change names of pci related data structure
 - [PATCH v6 5/5] eal: Fix uio mapping differences between linuxapp and bsdapp

Some functions will be consolidated after applying the patches, because
these functions are implemented in both Linux and BSD code.

PATCH v2 changes:
 - Fix license of eal_common_pci_uio.c

PATCH v1 changes:
 - Rebase to below latest patch series.
   - [PATCH v6] Clean up pci uio implementations


Tetsuya.Mukawa (8):
  eal: Add pci_uio_alloc_uio_resource()
  eal: Add pci_uio_map_uio_resource_by_index()
  eal: Consolidate pci_map and mapped_pci_resource of linuxapp and
    bsdapp
  eal: Consolidate rte_eal_pci_probe/close_one_driver() of linuxapp and
    bsdapp
  eal: Consolidate pci_map/unmap_device() of linuxapp and bsdapp
  eal: Consolidate pci_map/unmap_resource() of linuxapp and bsdapp
  eal: Consolidate pci uio functions of linuxapp and bsdapp
  eal: Enable Port Hotplug as default in Linux and BSD

[dpdk-dev] [PATCH v3 1/8] eal: Add pci_uio_alloc_uio_resource()

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch adds a new function called pci_uio_alloc_uio_resource().
The function hides how to prepare uio resource in linuxapp and bsdapp.
With the function, pci_uio_map_resource() will be more abstracted.

[dpdk-dev] [PATCH v3 2/8] eal: Add pci_uio_map_uio_resource_by_index()

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch adds a new function called pci_uio_map_resource_by_index().
The function hides how to map uio resource in linuxapp and bsdapp.
With the function, pci_uio_map_resource() will be more abstracted.

[dpdk-dev] [PATCH v3 4/8] eal: Consolidate rte_eal_pci_probe/close_one_driver() of linuxapp and bsdapp

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch consolidates below functions, and implements these in common
eal code.
 - rte_eal_pci_probe_one_driver()
 - rte_eal_pci_close_one_driver()

Because pci_map_device() is only implemented in linuxapp, the patch
implements it in bsdapp too. This implemented function will be merged to
linuxapp one with later patch.

Hi Bernard,

Could I make sure this comment?
Is it okay to change copyright of Intel like below?
- Copyright(c) 2010-2014 Intel Corporation. All rights reserved.
+ Copyright(c) 2010-2015 Intel Corporation. All rights reserved.

Or do you suggest it's better to add my company copyright below Intel?

Regards,
Tetsuya

Hi Bernard,

I haven't involved this fixing in latest patch series.
(Probably deadline will come soon, but my patches still have some
comments, so I will submit the patches that fix such issues.)
Even if we need to change copyright, it'll be very easy. In the case, I
will send new version patch series to fix it.

Regards,
Tetsuya

[dpdk-dev] [PATCH v3 8/8] eal: Enable Port Hotplug as default in Linux and BSD

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch removes CONFIG_RTE_LIBRTE_EAL_HOTPLUG option, and enables it
as default in both Linux and BSD.
Also, to support port hotplug, rte_eal_pci_scan() and below missing
symbols should be exported to ethdev library.
 - rte_eal_parse_devargs_str()
 - rte_eal_pci_close_one()
 - rte_eal_pci_probe_one()
 - rte_eal_pci_scan()
 - rte_eal_vdev_init()
 - rte_eal_vdev_uninit()

[dpdk-dev] [PATCH v4] eal: Enable Port Hotplug as default in Linux and BSD

[Tetsuya Mukawa]

From: "Tetsuya.Mukawa" <mukawa@igel.co.jp>

This patch removes CONFIG_RTE_LIBRTE_EAL_HOTPLUG option, and enables it
as default in both Linux and BSD.
Also, to support port hotplug, rte_eal_pci_scan() and below missing
symbols should be exported to ethdev library.
 - rte_eal_parse_devargs_str()
 - rte_eal_pci_close_one()
 - rte_eal_pci_probe_one()
 - rte_eal_pci_scan()
 - rte_eal_vdev_init()
 - rte_eal_vdev_uninit()

Signed-off-by: Tetsuya Mukawa <mukawa@igel.co.jp>

Hi Tetsuya,

Would it be cleaner to add this patch to the  [PATCH  v7 12/12] patch set as  patch 13 rather than having it as a separate patch?

Regards,

Bernard.

The other patch set is cleanup, merging BSD and Linuxapp code, so I think it's
best kept as a separate set. New features I'd suggest keeping separate from
cleanup. 
That being said, it is only one patch, so it probably doesn't matter much either
way. :-)

The majority of patches in this set seem to be more concerned with cleaning up
common code between linux and FreeBSD rather than adding hotplug support. Are those
changes better made as part of the previous patchset listed as a requirement of
this?

Hi Bruce,

I will move all most all patches to previous patch series.
Also, when I move, I will just add patches to previous series for reviewers.
(I will not change previous patches at all.)

[dpdk-dev] [PATCH 8/8] eal: Enable Port Hotplug as default in Linux and BSD

[Tetsuya Mukawa]

This patch removes CONFIG_RTE_LIBRTE_EAL_HOTPLUG option, and enables it
as default in both Linux and BSD.
Also, to support port hotplug, rte_eal_pci_scan() and below missing
symbols should be exported to ethdev library.
 - rte_eal_parse_devargs_str()
 - rte_eal_pci_close_one()
 - rte_eal_pci_probe_one()
 - rte_eal_pci_scan()
 - rte_eal_vdev_init()
 - rte_eal_vdev_uninit()
