From ac71494934c475e3f51e5e3e64a12f57618d82a4 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 8 Nov 2015 07:47:13 +0100 Subject: Bluetooth: Add support for controller specific logging To enable controller specific logging, the userspace daemon has to have the ability to log per controller. To facilitate this support, provide a dedicated logging channel. Messages in this channel will be included in the monitor queue and with that also forwarded to monitoring tools along with the actual hardware traces. All messages from the logging channel are timestamped and with that allow an easy correlation between userspace messages and hardware events. This will increase the ability to debug problems faster.
