.Sh DESCRIPTION
|
2003-10-23 01:54:06 +00:00
|
|
|
Each device has a quiet flag associated with it.
|
|
|
|
A device is
|
1999-06-22 18:09:54 +00:00
|
|
|
verbose by default when it is created but may be quieted to prevent
|
2016-09-12 18:06:42 +00:00
|
|
|
printing of the device identification string during attach
|
|
|
|
and printing of a message during detach.
|
1999-06-22 18:09:54 +00:00
|
|
|
To quiet a device, call
|
2016-09-12 18:06:42 +00:00
|
|
|
.Fn device_quiet
|
|
|
|
during a device driver probe routine.
|
|
|
|
To re-enable probe messages,
|
2000-12-29 09:18:45 +00:00
|
|
|
call
|
2002-12-24 13:41:48 +00:00
|
|
|
.Fn device_verbose .
|
2000-12-29 09:18:45 +00:00
|
|
|
To test to see if a device is quieted, call
|
2002-12-24 13:41:48 +00:00
|
|
|
.Fn device_is_quiet .
|
2016-09-12 18:06:42 +00:00
|
|
|
.Pp
|
|
|
|
Devices are implicitly marked verbose after a driver detaches.
