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.
