^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		stm_source device linkage to stm device, where its tracing data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		is directed. Reads return an existing connection or "<none>" if
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		this stm_source is not connected to any stm device yet.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		Write an existing (registered) stm device's name here to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		connect that device. If a device is already connected to this
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		stm_source, it will first be disconnected.
