The Firmware sends HTT event to host whenever there is a backpressure on RX rings, Handling such event and dumping info on the console under the "ATH11K_DBG_DP_HTT" debug level. Fetching RX ring backpressure histogram from FW via htt_stats debugfs. #echo "24" > /sys/kernel/debug/ath11k/ipq8074/macX/htt_stats_type #cat /sys/kernel/debug/ath11k/ipq8074/macX/htt_stats Signed-off-by: Vikas Patel <vikpatel@codeaurora.org> Signed-off-by: Sriram R <srirrama@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
