From e88975ca37d10a486cf3a3c7199a669eb393c123 Mon Sep 17 00:00:00 2001 From: Anilkumar Kolli Date: Fri, 12 Oct 2018 11:33:28 +0530 Subject: ath10k: dump tx stats in rate table format This patch adds the tx statistics pkts/bytes dump in rate table format. Dump format table is similar to http://mcsindex.com/ Tested on QCA9984/QCA4019/QCA988x Firmware: 10.4-3.5.3-00057 10.2.4-1.0-00037 command: cat /sys/kernel/debug/ieee80211/phy0/netdev\:wlan0/ stations//tx_stats Signed-off-by: Anilkumar Kolli Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath10k/core.h | 1 + drivers/net/wireless/ath/ath10k/debugfs_sta.c | 12 +++++++++++- drivers/net/wireless/ath/ath10k/htt_rx.c | 17 ++++++++++++++++- drivers/net/wireless/ath/ath10k/wmi.h | 1 + 4 files changed, 29 insertions(+), 2 deletions(-) (limited to 'drivers/net/wireless/ath/ath10k') diff --git a/drivers/net/wireless/ath/ath10k/core.h b/drivers/net/wireless/ath/ath10k/core.h index 009a4936a7ed..7d8d4e004e31 100644 --- a/drivers/net/wireless/ath/ath10k/core.h +++ b/drivers/net/wireless/ath/ath10k/core.h @@ -474,6 +474,7 @@ struct ath10k_htt_data_stats { u64 bw[ATH10K_COUNTER_TYPE_MAX][ATH10K_BW_NUM]; u64 nss[ATH10K_COUNTER_TYPE_MAX][ATH10K_NSS_NUM]; u64 gi[ATH10K_COUNTER_TYPE_MAX][ATH10K_GI_NUM]; + u64 rate_table[ATH10K_COUNTER_TYPE_MAX][ATH10K_RATE_TABLE_NUM]; }; struct ath10k_htt_tx_stats { diff --git a/drivers/net/wireless/ath/ath10k/debugfs_sta.c b/drivers/net/wireless/ath/ath10k/debugfs_sta.c index b09cdc699c69..0f3fd65a459e 100644 --- a/drivers/net/wireless/ath/ath10k/debugfs_sta.c +++ b/drivers/net/wireless/ath/ath10k/debugfs_sta.c @@ -665,7 +665,7 @@ static ssize_t ath10k_dbg_sta_dump_tx_stats(struct file *file, "retry", "ampdu"}; const char *str[ATH10K_COUNTER_TYPE_MAX] = {"bytes", "packets"}; int len = 0, i, j, k, retval = 0; - const int size = 2 * 4096; + const int size = 16 * 4096; char *buf; buf = kzalloc(size, GFP_KERNEL); @@ -719,6 +719,16 @@ static ssize_t ath10k_dbg_sta_dump_tx_stats(struct file *file, len += scnprintf(buf + len, size - len, "%llu ", stats->legacy[j][i]); len += scnprintf(buf + len, size - len, "\n"); + len += scnprintf(buf + len, size - len, + " Rate table %s (1,2 ...
