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

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.

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