From 2289188c273e2ce6aab9ff7a7972da40a8e82efb Mon Sep 17 00:00:00 2001 From: Janusz Dziedzic Date: Mon, 24 Mar 2014 21:24:58 +0100 Subject: [PATCH] ath10k: fix rssi and rate reporting RSSI and RATES fields are valid only when START_VALID bit is set. So, in current implementation we have to remember/caclulate them when START_VALID and report the same when only END_VALID is set. Currently during heavy traffic we could have: - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID - 10 packets with START_VALID - correct RSSI and RATES - 10 packets with END_VALID ... Next using monitor interface we will see: - 10 packets with correct rssi/rates - 10 packets with rssi=-95/rate=6Mbps Signed-off-by: Janusz Dziedzic Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath10k/htt_rx.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) diff --git a/drivers/net/wireless/ath/ath10k/htt_rx.c b/drivers/net/wireless/ath/ath10k/htt_rx.c index be25e160d5f0..f7ecc108ef80 100644 --- a/drivers/net/wireless/ath/ath10k/htt_rx.c +++ b/drivers/net/wireless/ath/ath10k/htt_rx.c @@ -1154,8 +1154,6 @@ static void ath10k_htt_rx_handler(struct ath10k_htt *htt, lockdep_assert_held(&htt->rx_ring.lock); - memset(rx_status, 0, sizeof(*rx_status)); - fw_desc_len = __le16_to_cpu(rx->prefix.fw_rx_desc_bytes); fw_desc = (u8 *)&rx->fw_desc; @@ -1164,8 +1162,11 @@ static void ath10k_htt_rx_handler(struct ath10k_htt *htt, mpdu_ranges = htt_rx_ind_get_mpdu_ranges(rx); /* Fill this once, while this is per-ppdu */ - rx_status->signal = ATH10K_DEFAULT_NOISE_FLOOR; - rx_status->signal += rx->ppdu.combined_rssi; + if (rx->ppdu.info0 & HTT_RX_INDICATION_INFO0_START_VALID) { + memset(rx_status, 0, sizeof(*rx_status)); + rx_status->signal = ATH10K_DEFAULT_NOISE_FLOOR + + rx->ppdu.combined_rssi; + } if (rx->ppdu.info0 & HTT_RX_INDICATION_INFO0_END_VALID) { /* TSF available only in 32-bit */ -- 2.39.5
