Hi Alain, > From a high level, this looks good for me although I agree, this is an > order of magnitude bigger in terms of scope.

I like to get some review on my idea first. What we could do is work on the BT_DBG etc infrastructure to allow switching when dynamic_debug is not available. Then you would use some debugfs toggle in /sys/kernel/debug/bluetooth since that is no stable API for us (and of course the clear understanding that this toggle is temporary). Regards Marcel
