By default shared mem DIAG based fw logging is enabled. To support WMI copy engine based fw logging add QMI control message to enable WMI copy engine based fw logging. Enable WMI based fw logging using fw_diag_log module parameter. insmod ath10k_core.ko fw_diag_log=1 DIAG utility(https://github.com/andersson/diag) implements extraction of diagnostics related messages between application processor and various subsystems while shared mem DIAG based fw logging is enabled.
