Only a concern about the implementation, 'RTE_TEST_PMD_RECORD_CORE_CYCLES' and 'RTE_TEST_PMD_RECORD_CORE_RX_CYCLES' are both using same variable, like 'start_rx_tsc', is there an assumption that both won't be enabled at same time? I think better to able to enable CORE_CYCLES, RX_CYCLES and TX_CYCLES separately / independently. Another think to consider, for long term - not for this patch, to move introduce RX/TX ifdefs to ethdev Rx/Tx functions so that all applications can use them, not just testpmd. >> >> Bruce, if proposed runtime extension is acceptable - I will update the patch. >> > Ok for me.> > Thanks, > /Bruce >
