device_quiet, device_verbose, device_is_quiet — manipulate device quiet flag


#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);


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() dur‐ ing 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.
