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)
36 depends on B43 && (SSB = y || SSB = B43)

40 config B43_PCI_AUTOSELECT
42 depends on B43 && SSB_PCIHOST_POSSIBLE
44 select SSB_B43_PCI_BRIDGE

55 bool "Broadcom 43xx PCMCIA device support"
56 depends on B43 && SSB_PCMCIAHOST_POSSIBLE
59 Broadcom 43xx PCMCIA device support.
61 Support for 16bit PCMCIA devices.
62 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
63 devices, but 32bit CardBUS devices. CardBUS devices are supported
64 out of the box by b43.
66 With this config option you can drive b43 cards in
67 CompactFlash formfactor in a PCMCIA adaptor.
68 CF b43 cards can sometimes be found in handheld PCs.
70 It's safe to select Y here, even if you don't have a B43 PCMCIA device.
75 bool "Broadcom 43xx SDIO device support"
76 depends on B43 && SSB_SDIOHOST_POSSIBLE
79 Broadcom 43xx device support for Soft-MAC SDIO devices.
81 With this config option you can drive Soft-MAC b43 cards with a
82 Secure Digital I/O interface.
83 This includes the WLAN daughter card found on the Nintendo Wii
85 Note that this does not support Broadcom 43xx Full-MAC devices.
87 It's safe to select Y here, even if you don't have a B43 SDIO device.
91 #Data transfers to the device via PIO. We want it as a fallback even
106 bool "Support for 802.11n (N-PHY) devices"
110 Support for the N-PHY.
112 This enables support for devices with N-PHY.
114 Say N if you expect high stability and performance. Saying Y will not
115 affect other devices support and may provide support for basic needs.
118 bool "Support for low-power (LP-PHY) devices"
122 Support for the LP-PHY.
123 The LP-PHY is a low-power PHY built into some notebooks
124 and embedded devices. It supports 802.11a/b/g
125 (802.11a support is optional, and currently disabled).
128 bool "Support for HT-PHY (high throughput) devices"
129 depends on B43 && B43_BCMA
132 Support for the HT-PHY.
134 Enables support for BCM4331 and possibly other chipsets with that PHY.
137 bool "Support for LCN-PHY devices (BROKEN)"
138 depends on B43 && BROKEN
140 Support for the LCN-PHY.
142 Say N, this is BROKEN and crashes driver.
144 # This config option automatically enables b43 LEDS support,
148 depends on B43 && MAC80211_LEDS && (LEDS_CLASS = y || LEDS_CLASS = B43)
151 # This config option automatically enables b43 HW-RNG support,
152 # if the HW-RNG core is enabled.
155 depends on B43 && (HW_RANDOM = y || HW_RANDOM = B43)
159 bool "Broadcom 43xx debugging"
162 Broadcom 43xx debugging.
164 This adds additional runtime sanity checks and statistics to the driver.
165 These checks and statistics might be expensive and hurt the runtime
166 performance of your system.
167 This also adds the b43 debugfs interface.
169 Do not enable this, unless you are debugging the driver.
171 Say N, if you are a distributor or user building a release kernel
173 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
