Subject: [dpdk-dev] [PATCH v2 0/5] lpm lookup with sve support
Date: Fri,  8 Jan 2021 08:25:18 +0000
Message-ID: <20210108082523.1062058-1-ruifeng.wang@arm.com> (raw)
In-Reply-To: <20201218101210.356836-1-ruifeng.wang@arm.com>

Added lpm4 lookupx4 implementation by using Arm SVE extension.
The SVE is Scalable Vector Extension which is exposed to the
user with a vector length agnostic interface.
Refer to [1] for more information about SVE.

Configuration was added for Neoverse N2 CPU which has SVE support.

Some bugs were fixed so compiling with sve enabled can pass.

v2:
Fixed tbl8 group index calculation. (Vladimir)
Added N2 config.
Fixed compiling when sve was enabled.
