2 tristate "Broadcom BCM43xx wireless support"
3 depends on PCI && IEEE80211 && IEEE80211_SOFTMAC && NET_RADIO && EXPERIMENTAL
7 This is an experimental driver for the Broadcom 43xx wireless chip,
8 found in the Apple Airport Extreme and various other devices.
11 bool "Broadcom BCM43xx debugging (RECOMMENDED)"
15 Broadcom 43xx debugging messages.
16 Say Y, because the driver is still very experimental and
17 this will help you get it running.
28 prompt "BCM43xx data transfer mode"
30 default BCM43XX_DMA_AND_PIO_MODE
32 config BCM43XX_DMA_AND_PIO_MODE
37 Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
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.
45 config BCM43XX_DMA_MODE
46 bool "DMA (Direct Memory Access) only"
49 Only include Direct Memory Access (DMA).
50 This reduces the size of the driver module, by omitting the PIO code.
52 config BCM43XX_PIO_MODE
53 bool "PIO (Programmed I/O) only"
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.
64 Only use PIO, if DMA does not work for you.
