BUS_ACTIVATE_RESOURCE(9) BSD Kernel Developer's Manual BUS_ACTIVATE_RESOURCE(9)NAME
bus_activate_resource, bus_deactivate_resource -- activate or deactivate a resource
bus_activate_resource(device_t dev, int type, int rid, struct resource *r);
bus_deactivate_resource(device_t dev, int type, int rid, struct resource *r);
These functions activate or deactivate a previously allocated resource. In general, resources must be activated before they can be accessed
by the driver so that the bus driver can map the resource into the devices space.
The arguments are as follows:
dev The device that requests ownership of the resource. Before allocation, the resource is owned by the parent bus.
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 pointer to a bus specific handle that identifies the resource being allocated.
r A pointer to the struct resource returned by bus_alloc_resource(9).
Zero is returned on success, otherwise an error is returned.
