Date: Wed, 5 Oct 2022 01:31:40 -0700 From: Joe Damato <jdamato@...tly.com> To: intel-wired-lan@...ts.osuosl.org Cc: netdev@...r.kernel.org, kuba@...nel.org, davem@...emloft.net, anthony.l.nguyen@...el.com, jesse.brandeburg@...el.com, Joe Damato <jdamato@...tly.com> Subject: [next-queue 0/3] i40e: Add an i40e_napi_poll tracepoint Greetings: Debugging and tuning the NAPI and i40e NIC parameters can be a bit tricky as there are many different options to test. This change adds a tracepoint to i40e_napi_poll which exposes a lot of helpful debug information for users who'd like to get a better understanding of how their NIC is performing as they adjust various parameters and tuning knobs. Some tweaks to i40e to support this information are made along the way; including a tweak to i40e_clean_tx_irq (and i40e_clean_xdp_tx_irq, etc) which returns the actual number of packets processed. Thanks, Joe Joe Damato (3): i40e: Store the irq number in i40e_q_vector i40e: i40e_clean_tx_irq returns work done i40e: Add i40e_napi_poll tracepoint drivers/net/ethernet/intel/i40e/i40e.h | 1 + drivers/net/ethernet/intel/i40e/i40e_main.c | 1 + drivers/net/ethernet/intel/i40e/i40e_trace.h | 50 ++++++++++++++++++++++++++++ drivers/net/ethernet/intel/i40e/i40e_txrx.c | 27 +++++++++------ drivers/net/ethernet/intel/i40e/i40e_xsk.c | 12 +++---- drivers/net/ethernet/intel/i40e/i40e_xsk.h | 2 +- 6 files changed, 75 insertions(+), 18 deletions(-) -- 2.7.4
