From d1ce37b7831ac6445c60f34b680f7214359e87ab Mon Sep 17 00:00:00 2001 From: Kan Yan Date: Mon, 11 Feb 2019 18:47:52 +0200 Subject: ath10k: report estimated frame transmit airtime to improve fairness MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The airtime of a transmitted frame will be estimated from last used tx rate which the firmware reports with the peer stats feature (WMI_SERVICE_PEER_STATS). The airtime is computed on the tx path and it will be reported to mac80211 upon tx completion. This change is based on Kan's orginal commit in Chromium tree ("CHROMIUM: ath10k: Implementing airtime fairness based TX scheduler") ref: https://chromium-review.googlesource.com/588190 Tested on QCA4019 with firmware version 10.4-3.2.1.1-00015 Tested on QCA9984 with firmware version 10.4-3.9.0.1-00005 Signed-off-by: Kan Yan [rmanohar@codeaurora.org: ported only the airtime computation] Signed-off-by: Rajkumar Manoharan [toke@redhat.com: Rebase to mac80211-next, add test note] Signed-off-by: Toke Høiland-Jørgensen Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath10k/htt_rx.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/net/wireless/ath/ath10k/htt_rx.c') diff --git a/drivers/net/wireless/ath/ath10k/htt_rx.c b/drivers/net/wireless/ath/ath10k/htt_rx.c index 98c525189087..77f494d52ec3 100644 --- a/drivers/net/wireless/ath/ath10k/htt_rx.c +++ b/drivers/net/wireless/ath/ath10k/htt_rx.c @@ -3080,6 +3080,7 @@ ath10k_update_per_peer_tx_stats(struct ath10k *ar, arsta->txrate.nss = txrate.nss; arsta->txrate.bw = ath10k_bw_to_mac80211_bw(txrate.bw); + arsta->last_tx_bitrate = cfg80211_calculate_bitrate(&arsta->txrate); if (sgi) arsta->txrate.flags |= RATE_INFO_FLAGS_SHORT_GI; -- cgit
