Subject: [PATCHv2 0/4] Add support to dump tx stats histogram
Date: Tue, 4 Sep 2018 12:15:12 +0530 [thread overview]
Message-ID: <1536043516-12462-1-git-send-email-akolli@codeaurora.org> (raw)
From: Anilkumar Kolli <akolli@codeaurora.org>
This patch series adds support to dump per station tx stats histogram.
These stats can be enabled through ath10k/enable_extd_tx_stats debugfs entry,
enabling this may impact in cpu usage and throughput.
ath10k/enable_extd_tx_stats is disabled by default.
Tx histogram has Per station tx stats which includes,
- pkts/bytes transmitted at all possible rates(mcs/nss/bw/gi).
- ACK fails count
- ampdu bytes/pkts transmitted at all possible rates(mcs/nss/bw/gi).
- BA fails count
- tx duration
Tested on QCA9984/QCA4019/QCA988x
Firmware: 10.4-3.5.3-00057
10.2.4-1.0-00037
Example output format:
