8 found in the Apple Airport Extreme and various other devices.

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

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

43 If unsure, choose this option.

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

52config BCM43XX_PIO_MODE
53 bool "PIO (Programmed I/O) only"
54 select BCM43XX_PIO
55 ---help---
56 Only include Programmed I/O (PIO).
57 This reduces the size of the driver module, by omitting the DMA code.
58 Please note that PIO transfers are slow (compared to DMA).

60 Also note that not all devices of the 43xx series support PIO.
61 The 4306 (Apple Airport Extreme and others) supports PIO, while
62 the 4318 is known to _not_ support PIO.
63
Michael Buesch77db31e2006-02-12 16:47:44 +010064 Only use PIO, if DMA does not work for you.
