[dpdk-dev] [PATCH v4 0/7] Infrastructure to support octeontx HW mempool manager

[Santosh Shukla]

v4:
Include 
- mempool deprecation changes, refer [1], 
- patches are rebased against v17.11-rc0.

v3:
In order to support octeontx HW mempool manager, the common mempool layer must
meet below condition.
- Object start address should be block size (total elem size) aligned.
- Object must have the physically contiguous address within the pool.

And right now mempool doesn't support both.

Patchset adds infrastrucure to support both condition in a _generic_ way.
Proposed solution won't effect existing mempool drivers or its functionality.

Summary:
Introducing capability flag. Now mempool drivers can advertise their
capabilities to common mempool layer(at the pool creation time).
Handlers are introduced in order to support capability flag.

Flags:
* MEMPOOL_F_CAPA_PHYS_CONTIG - If flag is set then Detect whether the object
has the physically contiguous address with in a hugepage.

* MEMPOOL_F_POOL_BLK_SZ_ALIGNED - If flag is set then make sure that object
addresses are block size aligned.

API:
Two handles are introduced:
* rte_mempool_ops_get_capability - advertise mempool manager capability.
* rte_mempool_ops_update_range - Update start and end address range to
HW mempool manager.

v3 --> v4:
* [01 - 02 - 03/07] mempool deprecation notice changes.
* [04 - 05 - 06 - 07/07] are v3 patches.

v2 --> v3:
(Note: v3 work is based on deprecation notice [1], It's for 17.11)
* Changed _version.map from 17.08 to 17.11.
* build fixes reported by stv_sys.
* Patchset rebased on upstream commit: da94a999.


v1 --> v2 :
* [01/06] Per deprecation notice [1], Changed rte_mempool 'flag'
  data type from int to unsigned int and removed flag param
  from _xmem_size/usage api.
* [02/06] Incorporated review feedback from v1 [2] (Suggested by Olivier)
* [03/06] Renamed flag to MEMPOOL_F_CAPA_PHYS_CONTIG
  and comment reworded. (Suggested by Olivier per v1 [3])
* [04/06] added new mempool arg in xmem_size/usage. (Suggested by Olivier)
* [05/06] patch description changed.
        - Removed elseif brakcet mix
        - removed sanity check for alignment
        - removed extra var delta
        - Removed __rte_unused from xmem_usage/size and added _BLK_SZ_ALIGN check.
        (Suggeted by Olivier per v1[4])
* [06/06] Added RTE_FUNC_PTR_OR_RET in rte_mempool_ops_update_ops.

Checkpatch status:
* WARNING: line over 80 characters
Noticed for debug messages.

Work history:
For v1, refer [5].
