DEVICE_QUIET(9) FreeBSD Kernel Developer's Manual DEVICE_QUIET(9)
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.
