I am seeing some crashes in iwlwifi, wanting to capture more info to debug it. So like outlined here,
I'm trying to enable / run trace-cmd. I added it to my build, but when I try to execute it,
root@OpenWrt:/# trace-cmd record -e iwlwifi trace-cmd: No such file or directory opening '/sys/kernel/debug/tracing/tracing_on'
Is this a known issue, or something I need to change to get the tracing working?
