From: Sven Eckelmann <seckelmann@xxxxxxxxx> Hi, it was observed that ath9k provides accumulated survey counters but ath10k neither provides deltas nor accumulated counters. Instead it returns some value which was returned at some point from the firmware. But as it turns out, this data is not reliable. To make it more useful, ath10k has to: * retrieve counters rather frequently for hardware which is known to use firmware versions with low number counter bits (for only 14-30s) * clean up received counter values * accumulate counters from firmware A comparison of the resulting output with these fixes can be seen under https://stats.freifunk-vogtland.net/d/ffv_node/nodeinfo?orgId=1&var-node=ac86749f4d60&fullscreen&panelId=5&from=1568782046974&to=1568807068706 The left side of the graph shows the output before the patches were applied and the right side the output with the patches applied. Just as reference, an ath9k device in the same building is https://stats.freifunk-vogtland.net/d/ffv_node/nodeinfo?orgId=1&var-node=ac86740037e0&fullscreen&panelId=5&from=1568782046974&to=1568807068706 Kind regards, Sven Sven Eckelmann (2): ath10k: report survey info as accumulated values ath10k: regularly fetch survey counters drivers/net/wireless/ath/ath10k/core.c | 8 ++++ drivers/net/wireless/ath/ath10k/core.h | 3 ++ drivers/net/wireless/ath/ath10k/hw.c | 13 +++-- drivers/net/wireless/ath/ath10k/mac.c | 52 ++++++++++++++++++++ drivers/net/wireless/ath/ath10k/mac.h | 3 ++ drivers/net/wireless/ath/ath10k/wmi.c | 66 ++++++++++++++++++++++---- 6 files changed, 130 insertions(+), 15 deletions(-) -- 2.20.1
