Subject: [dpdk-dev] [PATCH v2 2/2] net/mlx5: optimize mprq memcpy for AMD EPYC2 plaform
Date: Tue, 19 Oct 2021 16:17:24 +0530 [thread overview]
Message-ID: <20211019104724.19416-2-aman.kumar@vvdntech.in> (raw)
In-Reply-To: <20211019104724.19416-1-aman.kumar@vvdntech.in>
add non temporal load and temporal store for mprq memcpy.
This utilizes AMD EPYC2 optimized rte_memcpy* routines and
only enabled if config/x86/x86_amd_epyc_linux_gcc is build.
