BUS_SET_RESOURCE(9)	 BSD 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 re-
     sources 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 allo-
	     cated.

     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.
