[dpdk-dev] [PATCH v3 04/10] mempool/octeontx: add support for alloc

Santosh Shukla santosh.shukla at caviumnetworks.com
Sun Oct 8 14:40:05 CEST 2017


Upon pool allocation request by application, Octeontx FPA alloc
does following:
- Gets free pool from pci fpavf array.
- Uses mbox to communicate fpapf driver about,
  * gpool-id
  * pool block_sz
  * alignemnt
- Programs fpavf pool boundary.
