Subject: [dpdk-dev] [PATCH v2 0/3] Optimization for DPAA/DPAA2 for PA/VA Addressing
Date: Fri, 27 Apr 2018 22:50:55 +0530 [thread overview]
Message-ID: <20180427172058.26850-1-shreyansh.jain@nxp.com> (raw)
In-Reply-To: <20180427162556.22781-1-shreyansh.jain@nxp.com>
Once the hotplugging (6b42f7563) patchset were merged, DPAA2 Physical
Addressing mode and DPAA observed drastic performance drop (~95%)
This was because of an inherent assumption while doing some memory
translation that memsegs would be physically contiguous
This series attempts to add a workaround for that - a intermediary
one while complete solution is integrated
This work around creates a linked list of referenced buffers and
attempts to search through it during physical to virtual translations.

v2:
- fixed spelling mistakes in patch as commit
