From: Mohammed Shafi Shajakhan <mohammed@xxxxxxxxxxxxxxxx> Enable support for 'drv_sta_statistics' callback. Export rx_duration support if available to cfg80211/nl80211 This can also act as a placeholder for any new per STA stats support Signed-off-by: Mohammed Shafi Shajakhan <mohammed@xxxxxxxxxxxxxxxx> --- [v2] fixed condition for ath10k state Dependencies: 1. cfg80211/nl80211: Add support for NL80211_STA_INFO_RX_DURATION 2. iw: Add support for NL80211_STA_INFO_RX_DURATION netlink attribute 3. ath10k: Enable debugfs provision to enable Peer Stats feature drivers/net/wireless/ath/ath10k/debug.h | 4 ++++ drivers/net/wireless/ath/ath10k/debugfs_sta.c | 22 ++++++++++++++++++++++ drivers/net/wireless/ath/ath10k/mac.c | 1 + 3 files changed, 27 insertions(+) diff --git a/drivers/net/wireless/ath/ath10k/debug.h b/drivers/net/wireless/ath/ath10k/debug.h index 6206edd..01c500f 100644 --- a/drivers/net/wireless/ath/ath10k/debug.h +++ b/drivers/net/wireless/ath/ath10k/debug.h @@ -155,6 +155,10 @@ ath10k_debug_get_new_fw_crash_data(struct ath10k *ar) void ath10k_sta_add_debugfs(struct ieee80211_hw *hw, struct ieee80211_vif *vif, struct ieee80211_sta *sta, struct dentry *dir); void ath10k_sta_update_rx_duration(struct ath10k *ar, struct list_head *peer); +void ath10k_sta_statistics(struct ieee80211_hw *hw, struct ieee80211_vif *vif, + struct ieee80211_sta *sta, + struct station_info *sinfo); + #else static inline void ath10k_sta_update_rx_duration(struct ath10k *ar, struct list_head *peer) diff --git a/drivers/net/wireless/ath/ath10k/debugfs_sta.c b/drivers/net/wireless/ath/ath10k/debugfs_sta.c index 67ef75b..4c459f2 100644 --- a/drivers/net/wireless/ath/ath10k/debugfs_sta.c +++ b/drivers/net/wireless/ath/ath10k/debugfs_sta.c @@ -35,6 +35,28 @@ void ath10k_sta_update_rx_duration(struct ath10k *ar, struct list_head *head) rcu_read_unlock(); } +void ath10k_sta_statistics(struct ieee80211_hw *hw, struct ieee80211_vif *vif, + struct ieee80211_sta *sta, + struct station_info *sinfo) +{ + struct ath10k_sta *arsta = (struct ath10k_sta *)sta->drv_priv; + struct ath10k *ar = arsta->arvif->ar; + + mutex_lock(&ar->conf_mutex); + + if (ar->state != ATH10K_STATE_ON && + ar->state != ATH10K_STATE_RESTARTED) + goto out; + + if (!ath10k_peer_stats_enabled(ar)) + goto out; + + sinfo->rx_duration = arsta->rx_duration; + sinfo->filled |= 1ULL << NL80211_STA_INFO_RX_DURATION; +out: + mutex_unlock(&ar->conf_mutex); +} + static ssize_t ath10k_dbg_sta_read_aggr_mode(struct file *file, char __user *user_buf, size_t count, loff_t *ppos) diff --git a/drivers/net/wireless/ath/ath10k/mac.c b/drivers/net/wireless/ath/ath10k/mac.c index d5ef201..69a1dcf 100644 --- a/drivers/net/wireless/ath/ath10k/mac.c +++ b/drivers/net/wireless/ath/ath10k/mac.c @@ -6852,6 +6852,7 @@ static const struct ieee80211_ops ath10k_ops = { #endif #ifdef CONFIG_MAC80211_DEBUGFS .sta_add_debugfs = ath10k_sta_add_debugfs, + .sta_statistics = ath10k_sta_statistics, #endif }; -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
