DRIVER_MODULE(9)	 BSD Kernel Developer's Manual	      DRIVER_MODULE(9)

     DRIVER_MODULE — kernel driver declaration macro

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

     DRIVER_MODULE(name, busname, driver_t driver, devclass_t devclass,
	 modeventhand_t evh, void *arg);

     MULTI_DRIVER_MODULE(name, busname, driver_t drivers[],
	 devclass_t devclass, modeventhand_t evh, void *arg);

     The DRIVER_MODULE() macro declares a kernel driver.  DRIVER_MODULE()
     expands to the real driver declaration, where the phrase name is used as
     the naming prefix for the driver and its functions.  Note that it is sup‐
     plied as plain text, and not a char or char *.

     busname is the parent bus of the driver (PCI, ISA, PPBUS and others),
     e.g. ‘pci’, ‘isa’, or ‘ppbus’.

     The identifier used in DRIVER_MODULE() can be different from the driver
     name.  Also, the same driver identifier can exist on different busses,
     which is a pretty clean way of making front ends for different cards
     using the same driver on the same or different busses.  For example, the
     following is allowed:

     DRIVER_MODULE(foo, isa, foo_driver, foo_devclass, NULL, NULL);

     DRIVER_MODULE(foo, pci, foo_driver, foo_devclass, NULL, NULL);

     driver is the driver of type driver_t, which contains the information
     about the driver and is therefore one of the two most important parts of
     the call to DRIVER_MODULE().

     The devclass argument contains the kernel-internal information about the
     device, which will be used within the kernel driver module.

     The evh argument is the event handler which is called when the driver (or
     module) is loaded or unloaded (see module(9)).

     The arg is unused at this time and should be a NULL pointer.

     MULTI_DRIVER_MODULE() is a special version of DRIVER_MODULE(), which
     takes a list of drivers instead of a single driver instance.
