John W. Linville003faaa2008-01-27 22:48:37 -08008 This is an experimental driver for the Broadcom 43xx wireless
9 chip, found in the Apple Airport Extreme and various other
10 devices. This driver is deprecated and will be removed
11 from the kernel in the near future. It has been replaced
12 by the b43 and b43legacy drivers.

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

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

47 If unsure, choose this option.

53 Only include Direct Memory Access (DMA).
54 This reduces the size of the driver module, by omitting the PIO code.

58 select BCM43XX_PIO
59 ---help---
60 Only include Programmed I/O (PIO).
61 This reduces the size of the driver module, by omitting the DMA code.
62 Please note that PIO transfers are slow (compared to DMA).
Michael Buesch8bcab3f2006-02-12 16:52:10 +010063
64 Also note that not all devices of the 43xx series support PIO.
65 The 4306 (Apple Airport Extreme and others) supports PIO, while
66 the 4318 is known to _not_ support PIO.
67
Michael Buesch77db31e2006-02-12 16:47:44 +010068 Only use PIO, if DMA does not work for you.
