Member Function Documentation

uint32_t uart::read_ioport	(	l4_port_t	port,
		access_size	access_size
	)			[virtual]

Stub implementation, which always returns an invalid value.

Implemented here as a dummy to avoid unnecessary overriding in descendant classes. This function is intended to be overridden.

Reimplemented from device_base.

References device_base::change_iospace(), iospace_handler::INVALID, device_base::name(), and resource_manager::PHYSICAL.

int uart::write_ioport	(	l4_port_t	port,
		uint32_t	data,
		access_size	access_size
	)			[virtual]

Stub implementation, which always returns -L4_ENOTSUPP.

Implemented here as a dummy to avoid unnecessary overriding in descendant classes. This function is intended to be overridden.

Reimplemented from device_base.

References device_base::change_iospace(), device_base::name(), resource_manager::PHYSICAL, and serial_driver::write().
