[Bug 1052]: https://bugs.dpdk.org/show_bug.cgi?id=3D1052 Refer to patch v2 and RFC discussions: http://inbox.dpdk.org/dev/20221116180419.98937-1-mb@smartsharesystems.com= / http://inbox.dpdk.org/dev/98CBD80474FA8B44BF855DF32C47DC35D87489@smartser= ver.smartshare.dk/ Non-temporal memory copy ------------------------ The primary purpose of this feature is to avoid polluting the CPU's data cache when copying packets using the CPU, e.g. when capturing packets. E.g. copying a 32 packet burst of 1514 B packets reads 48 KB and writes 48 KB, and thus pollutes the entire L1 cache of a typical x86 CPU core with 64 KB data cache. The API for this feature is generic, but we will initially only = implement the feature for x86 architecture. This implementation can be used as inspiration for implementations for other architectures.
