Subject: [PATCH] ath11k: Add power save state change and power_save_duration
in the debugfs for each client.
This patch adds support to get the below power_save information
of each connected peer to AP. With WMI_PEER_STA_PS_STATECHG_EVENTID
event, below power save information is reported to user space via
debugfs.
Use the below commands in AP DUT to get the above power_save information.
To get the ps state of each sta:
cat /sys/kernel/debug/ieee80211/phyX/netdev::wlanX/stations/
XX:XX:XX:XX:XX:XX/peer_ps_state
If STA is in power save state, we get the peer_ps_state value as 1.
if STA is not in power save state, we get the peer_ps_state value as 0.
If ps_state event is disabled, we get the peer_ps_state value as 2.
We can enable/disable the ps_state events using the debugfs flag
"ps_state_enable"
echo Y > /sys/kernel/debug/ieee80211/phyX/ath11k/ps_state_enable
Y = 1 to enable and Y = 0 to disable
1.power_save_duration
2.time_since_station_in_power_save and
3.PS timekeeper to show a timeline about all PS state changes coming to AP,
with each event having information about MAC address of the peer connected,
Timestamp (real system time to milli seconds granularity) and
power save state.
To know the time_since_station_in_power_save:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/current_ps_duration
To know power_save_duration:
cat /sys/kernel/debug/ieee80211/phyX/netdev:wlanX/stations/
XX:XX:XX:XX:XX:XX/total_ps_duration
To reset the power_save_duration of all stations connected to AP:
echo 1 > /sys/kernel/debug/ieee80211/phyX/ath11k/reset_ps_duration
To enable/disable the ps_timekeeper:
echo Y > /sys/kernel/debug/ieee80211/phyX/ath11k/ps_timekeeper_enable
Y = 1 to enable and Y = 0 to disable.
To record PS timekeeer logs after enabling ps_timekeeper:
trace-cmd record -e ath11k_ps_timekeeper
