From 9f9df1a2535f6c890242b80d8538bd90ae540647 Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Thu, 18 Jan 2024 07:53:48 +0200 Subject: wifi: ath12k: add support for collecting firmware log Currently there is no way to collect firmware log because firmware does not send it to host. Also host does not handle WMI_DIAG_EVENTID which is used by firmware to upload firmware log. So add support for it by firstly enabling firmware log upload via a QMI message, and secondly processing WMI DIAG event to expose it to userspace via trace event. This change applies to both WCN7850 and QCN9274.
