H A D | trace.c | 9d740d63 Mon May 27 07:32:13 CDT 2019 Venkateswara Naralasetty <vnaralas@codeaurora.org> 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.
