[dpdk-dev] [PATCH v3 00/10] Cavium Octeontx external mempool driver

[Santosh Shukla]

v3:
- Incorporated mempool handle changes for
  * .get_capabilities
  * .register_memory_area
- Rebased on upstream tip commit: 3fb1ea032bd6ff8317af5dac9af901f1f324cab4


Patch implements the HW mempool offload driver for packets buffer.

A new pool handle called "octeontx_fpavf" introduced and is being configured
using eal arg ----mbuf-pool-ops-name="octeontx_fpavf".
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.
Refer [1] for rebased tree includes octeontx_fpavf mempool pmd + ONA pmd on
top for user to test for.

v2 --> v3:
(Major changes is above, below are minor)
- Incorporated doc review comment (John Macnamara)
- Renamed pool alloc/free/enq/deq/ge count v2 patch title
  from implement pool to add support for. (Identified by Thomas)
- Update doc with correct pool handle name from
  mbuf-pool-ops to mbuf-pool-ops-name.

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.
