[dpdk-dev] [PATCH v2 00/10] Cavium Octeontx external mempool driver

[Santosh Shukla]

v2:
Patch implements the HW mempool offload driver for packets buffer.
This HW mempool offload driver has dependency on:
- IOVA infrastrucure [1].
- Dynamically configure mempool handle (ie.. --mbuf-pool-ops eal arg) [2].
- Infrastructure to support octeontx HW mempool manager [3].

Mempool driver based on v17.11-rc0. Series has dependency
on upstream patches [1],[2],[3]. Git source repo for all those dependancy
patches + external mempool driver patches are located at [4].


A new pool handle called "octeontx_fpavf" introduced and is being configured
using eal arg ----mbuf-pool-ops="octeontx_fpavf", Note that this --eal arg is
under review.
Or
Can be configured statically like below:
CONFIG_RTE_MBUF_DEFAULT_MEMPOOL_OPS="octeontx_fpavf"

A new mempool driver specific CONFIG_RTE_LIBRTE_OCTEONTX_MEMPOOL config
is introduced.

Refer doc patch [10/10] for build and run steps.

v1 --> v2:
- Removed global rte_octeontx_fpa_bufpool_gpool() api, keeping  inline
function name octeontx_fpa_bufpool_gpool() in header file.
- Release doc cleanup.
- removed gpool2handle for loop iterate approach, Now gpool-id stays with
gpool_handle's (lsb 5bit of handle).

v1:
Patch summary:
- [1/10] : add mempool offload HW block definition.
- [2/10] : support for build and log infra, needed for pmd driver.
- [3/10] : probe mempool PCIe vf device
- [4/10] : support pool alloc
- [5/10] : support pool free
- [6/10] : support pool enq and deq
- [7/10] : support pool get count
- [8/10] : support pool get capability
- [9/10] : support pool update range
- [10/10] : doc and release info

Checkpatch status:
- Noticed false positive line over 80 char debug warning
- asm_ false +ve error.

Thanks.
