.Dd March 29, 2003 .Dt BUS_SET_RESOURCE 9 .Os .Sh NAME .Nm bus_set_resource .Nd "associate a definite resource with a given resource ID" .Sh SYNOPSIS n sys/param.h n sys/bus.h
p n machine/bus.h n sys/rman.h n machine/resource.h .Ft int .Fo bus_set_resource .Fa "device_t dev" "int type" "int rid" "u_long start" "u_long count" .Fc .Sh DESCRIPTION The .Fn bus_set_resource function sets the start address of the resource .Fa type , rid pair to be .Fa 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.
p The arguments are as follows: l -tag -width indent t Fa dev The device to set the resource on. t Fa type The type of resource you want to allocate. It is one of:
p l -tag -width ".Dv SYS_RES_MEMORY" -compact t Dv SYS_RES_IRQ for IRQs t Dv SYS_RES_DRQ for ISA DMA lines t Dv SYS_RES_IOPORT for I/O ports t Dv SYS_RES_MEMORY for I/O memory .El t Fa rid A bus-specific handle that identifies the resource being allocated. t Fa start The start address of this resource. t Fa count The length of the resource. For example, the size of the memory in bytes. .El .Sh RETURN VALUES Zero is returned on success, otherwise an error is returned. .Sh SEE ALSO .Xr bus_alloc_resource 9 , .Xr bus_get_resource 9 , .Xr device 9 , .Xr driver 9 .Sh AUTHORS This manual page was written by .An Warner Losh Aq imp@FreeBSD.org .
