MODULE_DRIVER(9)					   Device drivers infrastructure					  MODULE_DRIVER(9)

module_driver - Helper macro for drivers that don't do anything special in module init/exit. This eliminates a lot of boilerplate. Each module may only use this macro once, and calling it replaces module_init and module_exit. SYNOPSIS
module_driver(__driver, __register, __unregister, ...); ARGUMENTS
__driver driver name __register register function for this driver type __unregister unregister function for this driver type @...: Additional arguments to be passed to __register and __unregister. ... variable arguments DESCRIPTION
Use this macro to construct bus specific macros for registering drivers, and do not use it on its own. COPYRIGHT

DRIVER_MODULE -- kernel driver declaration macro SYNOPSIS
#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); DESCRIPTION
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 supplied 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. SEE ALSO
