NAME

       device_quiet, device_verbose, device_is_quiet — manipulate device quiet flag

SYNOPSIS

       #include <sys/param.h>
       #include <sys/bus.h>

       void
       device_quiet(device_t dev);

       void
       device_verbose(device_t dev);

       int
       device_is_quiet(device_t dev);

DESCRIPTION

       Each  device  has a quiet flag associated with it.  A device is verbose by default when it is created but
       may be quieted to prevent printing of the device identification string during attach and  printing  of  a
       message  during detach.  To quiet a device, call device_quiet() during a device driver probe routine.  To
       re-enable probe messages,  call  device_verbose().   To  test  to  see  if  a  device  is  quieted,  call
       device_is_quiet().

       Devices are implicitly marked verbose after a driver detaches.
