From: Shreyansh Jain Date: Mon, 15 Oct 2018 12:01:54 +0000 (+0530) Subject: common/dpaax: add library for PA/VA translation table X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2f3d633aa593c89c86dfb0e7df75e49ee05ad808;p=dpdk.git common/dpaax: add library for PA/VA translation table A common library, valid for dpaaX drivers, which is used to maintain a local copy of PA->VA translations. In case of physical addressing mode (one of the option for FSLMC, and only option for DPAA bus), the addresses of descriptors Rx'd are physical. These need to be converted into equivalent VA for rte_mbuf and other similar calls. Using the rte_mem_virt2iova or rte_mem_virt2phy is expensive. This library is an attempt to reduce the overall cost associated with this translation. A small table is maintained, containing continuous entries representing a continguous physical range. Each of these entries stores the equivalent VA, which is fed during mempool creation, or memory allocation/deallocation callbacks.
