BUS_ADJUST_RESOURCE(9)					   BSD Kernel Developer's Manual				    BUS_ADJUST_RESOURCE(9)

NAME
bus_adjust_resource -- adjust resource allocated from a parent bus SYNOPSIS
#include <sys/param.h> #include <sys/bus.h> #include <machine/bus.h> #include <sys/rman.h> #include <machine/resource.h> int bus_adjust_resource(device_t dev, int type, struct resource *r, u_long start, u_long end); DESCRIPTION
This function is used to ask the parent bus to adjust the resource range assigned to an allocated resource. The resource r should have been allocated by a previous call to bus_alloc_resource(9). The new resource range must overlap the existing range of r. The type argument should match the type argument passed to bus_alloc_resource(9) when the resource was initially allocated. Note that none of the constraints of the original allocation request such as alignment or boundary restrictions are checked by bus_adjust_resource(). It is the caller's responsibility to enforce any such requirements. RETURN VALUES
The bus_adjust_resource() method returns zero on success or an error code on failure. EXAMPLES
Grow an existing memory resource by 4096 bytes. struct resource *res; int error; error = bus_adjust_resource(dev, SYS_RES_MEMORY, res, rman_get_start(res), rman_get_end(res) + 0x1000); ERRORS
bus_adjust_resource() will fail if: [EINVAL] The dev device does not have a parent device. [EINVAL] The r resource is a shared resource. [EINVAL] The new address range does not overlap with the existing address range of r. [EBUSY] The new address range conflicts with another allocated resource. SEE ALSO
