| D | Kconfig | 74 bool "DMA + PIO"
78 Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
81 default DMA is used, otherwise PIO is used.
90 This reduces the size of the driver module, by omitting the PIO code.
93 bool "PIO (Programmed I/O) only"
96 Only include Programmed I/O (PIO).
98 Please note that PIO transfers are slow (compared to DMA).
100 Also note that not all devices of the b43legacy series support PIO.
102 You should use PIO only if DMA does not work for you.
