BUS_GENERIC_PRINT_CHILD(9) FreeBSD Kernel Developer's Manual NAME bus_generic_print_child, bus_print_child_domain, bus_print_child_footer, bus_print_child_header - generic implementation of BUS_PRINT_CHILD(9) SYNOPSIS #include <sys/param.h> #include <sys/bus.h> int bus_generic_print_child(device_t dev, device_t child); int bus_print_child_domain(device_t dev, device_t child); int bus_print_child_footer(device_t dev, device_t child); int bus_print_child_header(device_t dev, device_t child); DESCRIPTION bus_generic_print_child() prints out the default device announcement message. Given device `foo0' on bus `bar0' where foo0 has the description "FooCard 1234" and is associated with the NUMA domain 1, the following would be printed: foo0: <FooCard 1234> numa-domain 1 on bar0 bus_generic_print_child() calls the three helper functions bus_print_child_header(), bus_print_child_domain(), and bus_print_child_footer(). bus_print_child_header() outputs the device name and unit followed by the device description in angle brackets ("foo0: <FooCard 1234>"). bus_print_child_domain() outputs " numa-domain" followed by the domain number if bus_get_domain() returns a valid domain for the device ("numa-domain 1"). If dev is not associated witha valid domain, nothing is output. bus_print_child_footer() outputs the string " on" followed by the parent device's name and unit (" on bar0"). These functions can be used to implement BUS_PRINT_CHILD(9) in a bus driver if bus_generic_print_child() is not sufficient. RETURN VALUES The number of characters output.
