I'll look at this in more detail later, but in the meantime, do you have any test results to share? Specifically, how did you measure that the fairness part actually works? :) -Toke ___ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
[PATCH 0/6] Move TXQ scheduling and airtime fairness into mac80211
Toke, It is been a while since mac80211 TXQ discussion started. Here is the consolidated series of mac80211, ath9k and ath10k changes to move TXQ scheduling and airtime fairness into mac80211. The major changes w.r.t 5th RFC version are in may_transmit() API. Whenever the driver checks deficit for given TXQ, the list will be reordered so that driver/firmware RR quickly becomes in sync with mac80211 list. Also airtime tasklet approach cumbersome and causing regression in multi client performance. - Removed airtime kickout tasklet - Reworked on ieee80211_txq_may_transmit() API - Provided option to configure driver specific default airtime. - Bundled ath10k changes along with this series. -Rajkumar Rajkumar Manoharan (2): ath10k: migrate to mac80211 txq scheduling ath10k: reporting estimated tx airtime for fairness Toke Høiland-Jørgensen (4): mac80211: Add TXQ scheduling API cfg80211: Add airtime statistics and settings mac80211: Add airtime accounting and scheduling to TXQs ath9k: Switch to mac80211 TXQ scheduling and airtime APIs drivers/net/wireless/ath/ath10k/core.c | 2 - drivers/net/wireless/ath/ath10k/core.h | 8 +- drivers/net/wireless/ath/ath10k/htc.h | 1 - drivers/net/wireless/ath/ath10k/htt_rx.c | 9 ++ drivers/net/wireless/ath/ath10k/mac.c | 155 +++--- drivers/net/wireless/ath/ath10k/txrx.c | 4 + drivers/net/wireless/ath/ath9k/ath9k.h | 14 -- drivers/net/wireless/ath/ath9k/debug.c | 3 - drivers/net/wireless/ath/ath9k/debug.h | 8 - drivers/net/wireless/ath/ath9k/debug_sta.c | 70 - drivers/net/wireless/ath/ath9k/init.c | 3 +- drivers/net/wireless/ath/ath9k/recv.c | 9 +- drivers/net/wireless/ath/ath9k/xmit.c | 244 + include/net/cfg80211.h | 10 +- include/net/mac80211.h | 118 +- include/uapi/linux/nl80211.h | 15 ++ net/mac80211/agg-tx.c | 2 +- net/mac80211/cfg.c | 3 + net/mac80211/debugfs.c | 3 + net/mac80211/debugfs_sta.c | 50 +- net/mac80211/driver-ops.h | 9 ++ net/mac80211/ieee80211_i.h | 12 ++ net/mac80211/main.c| 9 ++ net/mac80211/sta_info.c| 54 ++- net/mac80211/sta_info.h| 13 ++ net/mac80211/status.c | 6 + net/mac80211/tx.c | 140 - net/wireless/nl80211.c | 28 28 files changed, 646 insertions(+), 356 deletions(-) -- 1.9.1 ___ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
