BUS_SET_RESOURCE(9)	    Kernel Developer's Manual	     BUS_SET_RESOURCE(9)

NAME
     bus_set_resource -- associate a definite resource with a given resource ID

SYNOPSIS
     #include <sys/param.h>
     #include <sys/bus.h>

     #include <machine/bus.h>
     #include <sys/rman.h>
     #include <machine/resource.h>

     int
     bus_set_resource(device_t dev, int type, int rid, rman_res_t start,
	 rman_res_t count);

DESCRIPTION
     The  bus_set_resource()  function	sets  the  start address of the resource
     type, rid pair to be count long.  Typically, client drivers do not use this
     interface.  Bus drivers, however, often use it to set up  the  resources  a
     client driver uses.

     The arguments are as follows:

     dev     The device to set the resource on.

     type    The type of resource you want to allocate.  It is one of:

	     SYS_RES_IRQ     for IRQs
	     SYS_RES_DRQ     for ISA DMA lines
	     SYS_RES_IOPORT  for I/O ports
	     SYS_RES_MEMORY  for I/O memory

     rid     A bus-specific handle that identifies the resource being allocated.

     start   The start address of this resource.

     count   The length of the resource.  For example, the size of the memory in
	     bytes.

RETURN VALUES
     Zero is returned on success, otherwise an error is returned.
