ath10k: Add wrapper function to ath10k debug ath10k_dbg() is called in ath10k_process_rx() with huge set of arguments which is causing CPU overhead even when debug_mask is not set. Good improvement was observed in the receive side performance when call to ath10k_dbg() is avoided in the RX path. Since currently all debug messages are sent via tracing infrastructure, we cannot entirely avoid calling ath10k_dbg. Therefore, call to ath10k_dbg() is made conditional based on tracing config in the driver. Trasmit performance remains unchanged with this patch; below are some experimental results with this patch and tracing disabled. mesh mode: w/o this patch with this patch Traffic TP CPU Usage TP CPU usage TCP 840Mbps 76.53% 960Mbps 78.14% UDP 1030Mbps 74.58% 1132Mbps 74.31% Infra mode: w/o this patch with this patch Traffic TP CPU Usage TP CPU usage TCP Rx 1241Mbps 80.89% 1270Mbps 73.50% UDP Rx 1433Mbps 81.77% 1472Mbps 72.80% Tested platform : IPQ8064 hardware used : QCA9984 firmware ver : ver 10.4-3.5.3-00057 Signed-off-by: Kan Yan <kyan@chromium.org> Signed-off-by: Venkateswara Naralasetty <vnaralas@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
