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 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 mem- ory in bytes. RETURN VALUES Zero is returned on success, otherwise an error is returned.
