From 6794be1deea818f21eae0a6b24c96ec5650ba758 Mon Sep 17 00:00:00 2001 From: Ilya Maximets Date: Thu, 11 Oct 2018 15:06:44 +0300 Subject: dpif-netdev-perf: Clarify frequency number. 'dpif-netdev/pmd-perf-show' command prints the frequency number calculated from the total number of cycles spent for iterations for the measured period. This number could be confusing, because users may think that it should be equal to CPU frequency, especially on non-x86 systems where TSC frequency likely does not match with CPU one. Moreover, counted TSC cycles could differ from the HW TSC cycles in case of a large number of PMD reloads, because cycles spent outside of the main polling loop are not taken into account anywhere. In this case the frequency will not match even TSC frequency. Let's clarify the meaning in order to avoid this misunderstanding. 'Cycles' replaced with 'Used TSC cycles', which describes how many TSC cycles consumed by the main polling loop. % of the total TSC cycles now printed instead of GHz frequency, because GHz is unclear for understanding, especially without knowing the exact TSC frequency.
