From: Ping-Ke Shih Date: Mon, 4 May 2020 10:50:08 +0000 (+0800) Subject: rtw88: 8723d: Add chip_ops::false_alarm_statistics X-Git-Tag: v5.15~3723^2~261^2~14 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=439d4a978d4883695d41c38d856676f3a0a806ba;p=platform%2Fkernel%2Flinux-starfive.git rtw88: 8723d: Add chip_ops::false_alarm_statistics This ops is used to do statistics of false alarm periodically, and then fine tune RX initial gain to adaptive different circumstance. There are three steps, hold/get/reset counter, to retrieve false alarm counters that consist of CCK and OFDM. In addition to false alarm counters, it also collects CRC ok/error counters of CCK, OFDM and HT.
