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.
