This is an experimental driver for the Broadcom 43xx wireless chip,

found in the Apple Airport Extreme and various other devices.

Say Y, because the driver is still very experimental and
|
|
this will help you get it running.

Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
|
|
data transfer modes.
|
|
The actually used mode is selectable through the module
|
|
parameter "pio". If the module parameter is pio=0, DMA is used.
|
|
Otherwise PIO is used. DMA is default.
|
|
|
|
If unsure, choose this option.

|

select BCM43XX_DMA
|

---help---
|

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

config BCM43XX_PIO_MODE

bool "PIO (Programmed I/O) only"
|

select BCM43XX_PIO
|
|
---help---
|
|
Only include Programmed I/O (PIO).
|
|
This reduces the size of the driver module, by omitting the DMA code.
|
|
Please note that PIO transfers are slow (compared to DMA).
|
|
|
|
Also note that not all devices of the 43xx series support PIO.
|
|
The 4306 (Apple Airport Extreme and others) supports PIO, while
|
|
the 4318 is known to _not_ support PIO.
|
|
|
|
Only use PIO, if DMA does not work for you.
