Channel active/busy time are showing incorrect(less than previous or sometimes zero) for successive survey dump command. example: Survey data from wlan0 frequency: 5180 MHz [in use] channel active time: 54995 ms channel busy time: 432 ms channel receive time: 0 ms channel transmit time: 59 ms Survey data from wlan0 frequency: 5180 MHz [in use] channel active time: 32592 ms channel busy time: 254 ms channel receive time: 0 ms channel transmit time: 0 ms This patch fix this issue by assigning 'wmi_bss_survey_req_type' as 'WMI_BSS_SURVEY_REQ_TYPE_READ' which accumulate survey data in FW and send survey data to driver upon the driver request. Wrap around is taken care by FW. hardware used : QCA9984 firmware ver : ver 10.4-3.5.3-00057 Signed-off-by: Venkateswara Naralasetty <vnaralas@xxxxxxxxxxxxxx> --- v2: * updated commit log. drivers/net/wireless/ath/ath10k/mac.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/wireless/ath/ath10k/mac.c b/drivers/net/wireless/ath/ath10k/mac.c index f068e2b..db93ab1 100644 --- a/drivers/net/wireless/ath/ath10k/mac.c +++ b/drivers/net/wireless/ath/ath10k/mac.c @@ -6837,7 +6837,7 @@ ath10k_mac_update_bss_chan_survey(struct ath10k *ar, struct ieee80211_channel *channel) { int ret; - enum wmi_bss_survey_req_type type = WMI_BSS_SURVEY_REQ_TYPE_READ_CLEAR; + enum wmi_bss_survey_req_type type = WMI_BSS_SURVEY_REQ_TYPE_READ; lockdep_assert_held(&ar->conf_mutex); -- 2.7.4
