config BCM43XX_MAC80211
tristate "Broadcom BCM43xx wireless support (mac80211 stack)"
depends on MAC80211 && WLAN_80211 && EXPERIMENTAL
select FW_LOADER
select SSB
select HW_RANDOM
---help---
This is an experimental driver for the Broadcom 43xx wireless chip,
found in the Apple Airport Extreme and various other devices.
config BCM43XX_MAC80211_PCI
bool "BCM43xx PCI device support"
depends on BCM43XX_MAC80211 && PCI
select SSB_PCIHOST
select SSB_DRIVER_PCICORE
default y
---help---
Broadcom 43xx PCI device support.
Say Y, if you have a BCM43xx device connected through the PCI bus.
Please note that most PC-CARD devices are (to the kernel) PCI devices,
too and not PCMCIA.
It's safe to select Y here, even if you don't have a BCM43xx PCI device.
config BCM43XX_MAC80211_PCMCIA
bool "BCM43xx PCMCIA device support"
depends on BCM43XX_MAC80211 && PCMCIA
select SSB_PCMCIAHOST
---help---
Broadcom 43xx PCMCIA device support.
Support for 16bit PCMCIA devices.
Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
devices, but 32bit CardBUS devices. CardBUS devices are supported
by "BCM43xx PCI device support".
With this config option you can drive bcm43xx cards in
CompactFlash formfactor in a PCMCIA adaptor.
CF bcm43xx cards can sometimes be found in handheld PCs.
It's safe to select Y here, even if you don't have a BCM43xx PCMCIA device.
If unsure, say N.
config BCM43XX_MAC80211_DEBUG
bool "Broadcom BCM43xx debugging (RECOMMENDED)"
depends on BCM43XX_MAC80211
select SSB_DEBUG if !SSB_SILENT
default y
---help---
Broadcom 43xx debugging messages.
Say Y, because the driver is still very experimental and
this will help you get it running.
config BCM43XX_MAC80211_DMA
bool
depends on BCM43XX_MAC80211
config BCM43XX_MAC80211_PIO
bool
depends on BCM43XX_MAC80211
choice
prompt "BCM43xx data transfer mode"
depends on BCM43XX_MAC80211
default BCM43XX_MAC80211_DMA_AND_PIO_MODE
config BCM43XX_MAC80211_DMA_AND_PIO_MODE
bool "DMA + PIO"
select BCM43XX_MAC80211_DMA
select BCM43XX_MAC80211_PIO
---help---
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.
config BCM43XX_MAC80211_DMA_MODE
bool "DMA (Direct Memory Access) only"
select BCM43XX_MAC80211_DMA
---help---
Only include Direct Memory Access (DMA).
This reduces the size of the driver module, by omitting the PIO code.
config BCM43XX_MAC80211_PIO_MODE
bool "PIO (Programmed I/O) only"
select BCM43XX_MAC80211_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.
