[shafi] thanks for taking time to do this, the change looks fine to me ! since 'ath10k_sta_update_rx_duration' is called right after 'ath10k_wmi_pull_fw_stats' this should properly update the rx_duration based on the current data > > Here's a diff of what I did: > > diff --git a/drivers/net/wireless/ath/ath10k/core.c b/drivers/net/wireless/ath/ath10k/core.c > index 58932c09efc5..b734345ab598 100644 > --- a/drivers/net/wireless/ath/ath10k/core.c > +++ b/drivers/net/wireless/ath/ath10k/core.c > @@ -180,7 +180,6 @@ static const struct ath10k_hw_params ath10k_hw_params_list[] = { > .board = QCA99X0_HW_2_0_BOARD_DATA_FILE, > .board_size = QCA99X0_BOARD_DATA_SZ, > .board_ext_size = QCA99X0_BOARD_EXT_DATA_SZ, > - .extd_peer_stats = true, > }, > }, > { > @@ -203,7 +202,6 @@ static const struct ath10k_hw_params ath10k_hw_params_list[] = { > .board = QCA9984_HW_1_0_BOARD_DATA_FILE, > .board_size = QCA99X0_BOARD_DATA_SZ, > .board_ext_size = QCA99X0_BOARD_EXT_DATA_SZ, > - .extd_peer_stats = true, > }, > }, > { > @@ -261,7 +259,6 @@ static const struct ath10k_hw_params ath10k_hw_params_list[] = { > .board = QCA4019_HW_1_0_BOARD_DATA_FILE, > .board_size = QCA4019_BOARD_DATA_SZ, > .board_ext_size = QCA4019_BOARD_EXT_DATA_SZ, > - .extd_peer_stats = true, > }, > }, > }; > diff --git a/drivers/net/wireless/ath/ath10k/core.h b/drivers/net/wireless/ath/ath10k/core.h > index 73a0b1ae1559..3707d8a707a2 100644 > --- a/drivers/net/wireless/ath/ath10k/core.h > +++ b/drivers/net/wireless/ath/ath10k/core.h > @@ -263,6 +263,7 @@ struct ath10k_fw_stats_pdev { > }; > > struct ath10k_fw_stats { > + bool extended; > struct list_head pdevs; > struct list_head vdevs; > struct list_head peers; > @@ -754,7 +755,6 @@ struct ath10k { > const char *board; > size_t board_size; > size_t board_ext_size; > - bool extd_peer_stats; > } fw; > } hw_params; > > diff --git a/drivers/net/wireless/ath/ath10k/debug.c b/drivers/net/wireless/ath/ath10k/debug.c > index 001c0a144614..355e1ae665f9 100644 > --- a/drivers/net/wireless/ath/ath10k/debug.c > +++ b/drivers/net/wireless/ath/ath10k/debug.c > @@ -327,6 +327,7 @@ static void ath10k_debug_fw_stats_reset(struct ath10k *ar) > { > spin_lock_bh(&ar->data_lock); > ar->debug.fw_stats_done = false; > + ar->debug.fw_stats.extended = false; > ath10k_fw_stats_pdevs_free(&ar->debug.fw_stats.pdevs); > ath10k_fw_stats_vdevs_free(&ar->debug.fw_stats.vdevs); > ath10k_fw_stats_peers_free(&ar->debug.fw_stats.peers); > diff --git a/drivers/net/wireless/ath/ath10k/debugfs_sta.c b/drivers/net/wireless/ath/ath10k/debugfs_sta.c > index af3d49af9eab..0da8a57e0ba7 100644 > --- a/drivers/net/wireless/ath/ath10k/debugfs_sta.c > +++ b/drivers/net/wireless/ath/ath10k/debugfs_sta.c > @@ -19,14 +19,14 @@ > #include "debug.h" > > static void ath10k_sta_update_extd_stats_rx_duration(struct ath10k *ar, > - struct list_head *head) > + struct ath10k_fw_stats *stats) > { > - struct ieee80211_sta *sta; > struct ath10k_fw_extd_stats_peer *peer; > + struct ieee80211_sta *sta; > struct ath10k_sta *arsta; > > rcu_read_lock(); > - list_for_each_entry(peer, head, list) { > + list_for_each_entry(peer, &stats->peers_extd, list) { > sta = ieee80211_find_sta_by_ifaddr(ar->hw, peer->peer_macaddr, > NULL); > if (!sta) > @@ -38,13 +38,14 @@ static void ath10k_sta_update_extd_stats_rx_duration(struct ath10k *ar, > } > > static void ath10k_sta_update_stats_rx_duration(struct ath10k *ar, > - struct list_head *head) > -{ struct ieee80211_sta *sta; > + struct ath10k_fw_stats *stats) > +{ > struct ath10k_fw_stats_peer *peer; > + struct ieee80211_sta *sta; > struct ath10k_sta *arsta; > > rcu_read_lock(); > - list_for_each_entry(peer, head, list) { > + list_for_each_entry(peer, &stats->peers, list) { > sta = ieee80211_find_sta_by_ifaddr(ar->hw, peer->peer_macaddr, > NULL); > if (!sta) > @@ -58,11 +59,10 @@ static void ath10k_sta_update_stats_rx_duration(struct ath10k *ar, > void ath10k_sta_update_rx_duration(struct ath10k *ar, > struct ath10k_fw_stats *stats) > { > - if (ar->hw_params.fw.extd_peer_stats) > - ath10k_sta_update_stats_rx_duration(ar, &stats->peers); > + if (stats->extended) > + ath10k_sta_update_extd_stats_rx_duration(ar, stats); > else > - ath10k_sta_update_extd_stats_rx_duration(ar, > - &stats->peers_extd); > + ath10k_sta_update_stats_rx_duration(ar, stats); > } > > static ssize_t ath10k_dbg_sta_read_aggr_mode(struct file *file, > diff --git a/drivers/net/wireless/ath/ath10k/wmi.c b/drivers/net/wireless/ath/ath10k/wmi.c > index 5f2d423b1c33..16bd79716a6c 100644 > --- a/drivers/net/wireless/ath/ath10k/wmi.c > +++ b/drivers/net/wireless/ath/ath10k/wmi.c > @@ -3008,6 +3008,8 @@ static int ath10k_wmi_10_4_op_pull_fw_stats(struct ath10k *ar, > if ((stats_id & WMI_10_4_STAT_PEER_EXTD) == 0) > return 0; > > + stats->extended = true; > + > for (i = 0; i < num_peer_stats; i++) { > const struct wmi_10_4_peer_extd_stats *src; > struct ath10k_fw_extd_stats_peer *dst; > > > -- > Kalle Valo
