Test-Label: intel-Functional Test-Status: SUCCESS _Functional PASS_ DPDK git repo: dpdk commit b4a635d5e5c072461e2c560a7501d8ebc73727af Author: Sivaprasad Tummala Date: Fri Oct 24 14:16:31 2025 +0000 test/ring_perf: add optional cross L3 core selection Enhances test_ring_perf to optionally select two cores on the same socket but on different L3 caches using hwloc. This allows performance characterization of ring library on processors with split L3 cache architectures, providing more realistic measurements of inter-core communication and cache effects. The feature is conditional on hwloc being present, ensuring builds succeed on systems without hwloc. Signed-off-by: Sivaprasad Tummala v3: * Localized hwloc dependency only to app/test for targeted linking. v2: * Localized hwloc dependency to app only. * Optimized get_two_l3caches() by moving socket and L3 cache ID retrieval to the outer loop.
