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.
