Implement DMA trace level based on modules. User can switch on/off for DMA trace of one module.
Are there any updates to userspace rmbox tools to use this feature ?
No currently. IMHO, we could use "echo/cat /sys/kernel/debug/sof/trace_level" to control it. So need I also add another control path to control it by rmbox? Thanks.
yeah, we could have a debugFS file "trace_control" and we would send :-
echo "VOL1.1:pipeline:2"
format is component:class:level
Some trace class may not bind with component. E.g. trace_ipc(). May we ignore component key in this case? Thanks.

This would set trace to level 2 on component "VOL1.1" for pipeline operations
cat trace_control
would list each widget and the trace level for that widget.
