From 25f49617b5c9c9afa829030f14606be6351d4771 Mon Sep 17 00:00:00 2001 From: Eric Huang Date: Fri, 21 Oct 2022 17:16:01 +0800 Subject: [PATCH] wifi: rtw89: add BW info for both TX and RX in phy_info In order to debug performance issue intuitively, add bandwidth information into debugfs entry phy_info. After applying this patch, it looks like: TX rate [0]: HE 2SS MCS-11 GI:0.8 BW:80 (hw_rate=0x19b) ==> agg_wait=1 (3500) RX rate [0]: HE 2SS MCS-9 GI:0.8 BW:80 (hw_rate=0x199) Signed-off-by: Eric Huang Signed-off-by: Ping-Ke Shih Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20221021091601.39884-1-pkshih@realtek.com --- drivers/net/wireless/realtek/rtw89/debug.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/drivers/net/wireless/realtek/rtw89/debug.c b/drivers/net/wireless/realtek/rtw89/debug.c index 8f27c88..cd44d9a 100644 --- a/drivers/net/wireless/realtek/rtw89/debug.c +++ b/drivers/net/wireless/realtek/rtw89/debug.c @@ -51,6 +51,22 @@ struct rtw89_debugfs_priv { }; }; +static const u16 rtw89_rate_info_bw_to_mhz_map[] = { + [RATE_INFO_BW_20] = 20, + [RATE_INFO_BW_40] = 40, + [RATE_INFO_BW_80] = 80, + [RATE_INFO_BW_160] = 160, + [RATE_INFO_BW_320] = 320, +}; + +static u16 rtw89_rate_info_bw_to_mhz(enum rate_info_bw bw) +{ + if (bw < ARRAY_SIZE(rtw89_rate_info_bw_to_mhz_map)) + return rtw89_rate_info_bw_to_mhz_map[bw]; + + return 0; +} + static int rtw89_debugfs_single_show(struct seq_file *m, void *v) { struct rtw89_debugfs_priv *debugfs_priv = m->private; @@ -2379,6 +2395,7 @@ static void rtw89_sta_info_get_iter(void *data, struct ieee80211_sta *sta) else seq_printf(m, "Legacy %d", rate->legacy); seq_printf(m, "%s", rtwsta->ra_report.might_fallback_legacy ?
