The recommended state 328c2ecf20Sopenharmony_ci for Input ports and Output ports should be disabled. When 338c2ecf20Sopenharmony_ci this switch is set the RapidIO subsystem will enable all 348c2ecf20Sopenharmony_ci ports for Input/Output direction to allow other traffic 358c2ecf20Sopenharmony_ci than Maintenance transfers. 368c2ecf20Sopenharmony_ci 378c2ecf20Sopenharmony_ciconfig RAPIDIO_DMA_ENGINE 388c2ecf20Sopenharmony_ci bool "DMA Engine support for RapidIO" 398c2ecf20Sopenharmony_ci depends on RAPIDIO 408c2ecf20Sopenharmony_ci depends on DMADEVICES 418c2ecf20Sopenharmony_ci select DMA_ENGINE 428c2ecf20Sopenharmony_ci help 438c2ecf20Sopenharmony_ci Say Y here if you want to use DMA Engine frameork for RapidIO data 448c2ecf20Sopenharmony_ci transfers to/from target RIO devices.
