2 tristate "Broadcom 43xx wireless support (mac80211 stack)"
3 depends on SSB_POSSIBLE && MAC80211 && HAS_DMA
7 b43 is a driver for the Broadcom 43xx series wireless devices.
9 Check "lspci" for something like
10 "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
11 to determine whether you own such a device.
13 This driver supports the new BCM43xx IEEE 802.11G devices, but not
14 the old IEEE 802.11B devices. Old devices are supported by
16 Note that this has nothing to do with the standard that your AccessPoint
17 supports (A, B, G or a combination).
18 IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
20 It is safe to include both b43 and b43legacy as the underlying glue
21 layer will automatically load the correct version for your device.
23 This driver uses V4 firmware, which must be installed separately using
26 This driver can be built as a module (recommended) that will be called "b43".
30 bool "Support for BCMA bus"
31 depends on B43 && (BCMA = y || BCMA = B43)
35 bool "Hardware support that overlaps with the brcmsmac driver"
42 depends on B43 && (SSB = y || SSB = B43)

46 config B43_PCI_AUTOSELECT
48 depends on B43 && SSB_PCIHOST_POSSIBLE
50 select SSB_B43_PCI_BRIDGE
53 # Auto-select SSB PCICORE driver, if possible

61 bool "Broadcom 43xx PCMCIA device support"
62 depends on B43 && SSB_PCMCIAHOST_POSSIBLE
65 Broadcom 43xx PCMCIA device support.
67 Support for 16bit PCMCIA devices.
68 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
69 devices, but 32bit CardBUS devices. CardBUS devices are supported
70 out of the box by b43.
72 With this config option you can drive b43 cards in
73 CompactFlash formfactor in a PCMCIA adaptor.
74 CF b43 cards can sometimes be found in handheld PCs.
76 It's safe to select Y here, even if you don't have a B43 PCMCIA device.
81 bool "Broadcom 43xx SDIO device support"
82 depends on B43 && SSB_SDIOHOST_POSSIBLE
85 Broadcom 43xx device support for Soft-MAC SDIO devices.
87 With this config option you can drive Soft-MAC b43 cards with a
88 Secure Digital I/O interface.
89 This includes the WLAN daughter card found on the Nintendo Wii
91 Note that this does not support Broadcom 43xx Full-MAC devices.
93 It's safe to select Y here, even if you don't have a B43 SDIO device.
97 #Data transfers to the device via PIO. We want it as a fallback even
112 bool "Support for 802.11n (N-PHY) devices"
116 Support for the N-PHY.
118 This enables support for devices with N-PHY.
120 Say N if you expect high stability and performance. Saying Y will not
121 affect other devices support and may provide support for basic needs.
124 bool "Support for low-power (LP-PHY) devices"
128 Support for the LP-PHY.
129 The LP-PHY is a low-power PHY built into some notebooks
130 and embedded devices. It supports 802.11a/b/g
131 (802.11a support is optional, and currently disabled).
134 bool "Support for HT-PHY (high throughput) devices"
135 depends on B43 && B43_BCMA
138 Support for the HT-PHY.
140 Enables support for BCM4331 and possibly other chipsets with that PHY.
143 bool "Support for LCN-PHY devices (BROKEN)"
144 depends on B43 && BROKEN
146 Support for the LCN-PHY.
148 Say N, this is BROKEN and crashes driver.
150 # This config option automatically enables b43 LEDS support,
154 depends on B43 && MAC80211_LEDS && (LEDS_CLASS = y || LEDS_CLASS = B43)
157 # This config option automatically enables b43 HW-RNG support,
158 # if the HW-RNG core is enabled.
161 depends on B43 && (HW_RANDOM = y || HW_RANDOM = B43)
165 bool "Broadcom 43xx debugging"
168 Broadcom 43xx debugging.
170 This adds additional runtime sanity checks and statistics to the driver.
171 These checks and statistics might be expensive and hurt the runtime
172 performance of your system.
173 This also adds the b43 debugfs interface.
175 Do not enable this, unless you are debugging the driver.
177 Say N, if you are a distributor or user building a release kernel
179 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
