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

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 (EXPERIMENTAL)"
76 depends on B43 && SSB_SDIOHOST_POSSIBLE && EXPERIMENTAL
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 (EXPERIMENTAL)"
107 depends on B43 && EXPERIMENTAL
109 Support for the N-PHY.
111 This enables support for devices with N-PHY.
113 Say N if you expect high stability and performance. Saying Y will not
114 affect other devices support and may provide support for basic needs.
117 bool "Support for low-power (LP-PHY) devices (EXPERIMENTAL)"
118 depends on B43 && EXPERIMENTAL
121 Support for the LP-PHY.
122 The LP-PHY is a low-power PHY built into some notebooks
123 and embedded devices. It supports 802.11a/g
124 (802.11a support is optional, and currently disabled).
127 bool "Support for HT-PHY devices (BROKEN)"
128 depends on B43 && BROKEN
130 Support for the HT-PHY.
132 Say N, this is BROKEN and crashes driver.
135 bool "Support for LCN-PHY devices (BROKEN)"
136 depends on B43 && BROKEN
138 Support for the LCN-PHY.
140 Say N, this is BROKEN and crashes driver.
142 # This config option automatically enables b43 LEDS support,
146 depends on B43 && MAC80211_LEDS && (LEDS_CLASS = y || LEDS_CLASS = B43)
149 # This config option automatically enables b43 HW-RNG support,
150 # if the HW-RNG core is enabled.
153 depends on B43 && (HW_RANDOM = y || HW_RANDOM = B43)
157 bool "Broadcom 43xx debugging"
160 Broadcom 43xx debugging.
162 This adds additional runtime sanity checks and statistics to the driver.
163 These checks and statistics might me expensive and hurt runtime performance
165 This also adds the b43 debugfs interface.
167 Do not enable this, unless you are debugging the driver.
169 Say N, if you are a distributor or user building a release kernel
171 Only say Y, if you are debugging a problem in the b43 driver sourcecode.
174 bool "Force usage of PIO instead of DMA"
175 depends on B43 && B43_DEBUG
177 This will disable DMA and always enable PIO instead.
180 This is only for debugging the PIO engine code. You do
181 _NOT_ want to enable this.
