[PATCH v2 3/6] wifi: ath12k: Support Uplink OFDMA Trigger Stats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dinesh Karthikeyan <quic_dinek@xxxxxxxxxxx>

Add support to request uplink trigger stats from firmware through
HTT stats type 26. These stats give information about uplink
OFDMA bandwidth, received RSSI, power headroom, QoS, data size,
PPDU info and pass/fail info for each user.

Note: MCC firmware version
WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
does not support tags HTT_STATS_RX_PDEV_UL_TRIG_STATS_TAG(94) and
HTT_STATS_RX_PDEV_UL_OFDMA_USER_STATS_TAG(95), currently.

Sample output:
-------------
echo 26 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type
cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats

quarter_ul_ofdma_rx_bw =  0:0, 1:0, 2:0, 3:0
.....
