16 Broadcom 43xx debugging messages.
17 Say Y, because the driver is still very experimental and
18 this will help you get it running.

38 Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
39 data transfer modes.
40 The actually used mode is selectable through the module
41 parameter "pio". If the module parameter is pio=0, DMA is used.
42 Otherwise PIO is used. DMA is default.

44 If unsure, choose this option.

48 select BCM43XX_DMA
49 ---help---
50 Only include Direct Memory Access (DMA).
51 This reduces the size of the driver module, by omitting the PIO code.

53config BCM43XX_PIO_MODE
54 bool "PIO (Programmed I/O) only"
55 select BCM43XX_PIO
56 ---help---
57 Only include Programmed I/O (PIO).
58 This reduces the size of the driver module, by omitting the DMA code.
59 Please note that PIO transfers are slow (compared to DMA).

61 Also note that not all devices of the 43xx series support PIO.
62 The 4306 (Apple Airport Extreme and others) supports PIO, while
63 the 4318 is known to _not_ support PIO.
64
Michael Buesch77db31e2006-02-12 16:47:44 +010065 Only use PIO, if DMA does not work for you.
