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.
