1config B43 2 tristate "Broadcom 43xx wireless support (mac80211 stack)" 3 depends on SSB_POSSIBLE && MAC80211 && HAS_DMA 4 select SSB 5 select FW_LOADER 6 ---help--- 7 b43 is a driver for the Broadcom 43xx series wireless devices. 8 9 Check "lspci" for something like 10 "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller" 11 to determine whether you own such a device. 12 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 15 the b43legacy driver. 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. 19 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. 22 23 This driver uses V4 firmware, which must be installed separately using 24 b43-fwcutter. 25 26 This driver can be built as a module (recommended) that will be called "b43". 27 If unsure, say M. 28 29config B43_BCMA 30 bool "Support for BCMA bus" 31 depends on B43 && BCMA 32 default y 33 34config B43_SSB 35 bool 36 depends on B43 && SSB 37 default y 38 39# Auto-select SSB PCI-HOST support, if possible 40config B43_PCI_AUTOSELECT 41 bool 42 depends on B43 && SSB_PCIHOST_POSSIBLE 43 select SSB_PCIHOST 44 select SSB_B43_PCI_BRIDGE 45 default y 46 47# Auto-select SSB PCICORE driver, if possible 48config B43_PCICORE_AUTOSELECT 49 bool 50 depends on B43 && SSB_DRIVER_PCICORE_POSSIBLE 51 select SSB_DRIVER_PCICORE 52 default y 53 54config B43_PCMCIA 55 bool "Broadcom 43xx PCMCIA device support" 56 depends on B43 && SSB_PCMCIAHOST_POSSIBLE 57 select SSB_PCMCIAHOST 58 ---help--- 59 Broadcom 43xx PCMCIA device support. 60 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. 65 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. 69 70 It's safe to select Y here, even if you don't have a B43 PCMCIA device. 71 72 If unsure, say N. 73 74config B43_SDIO 75 bool "Broadcom 43xx SDIO device support (EXPERIMENTAL)" 76 depends on B43 && SSB_SDIOHOST_POSSIBLE && EXPERIMENTAL 77 select SSB_SDIOHOST 78 ---help--- 79 Broadcom 43xx device support for Soft-MAC SDIO devices. 80 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 84 video game console. 85 Note that this does not support Broadcom 43xx Full-MAC devices. 86 87 It's safe to select Y here, even if you don't have a B43 SDIO device. 88 89 If unsure, say N. 90 91#Data transfers to the device via PIO. We want it as a fallback even 92# if we can do DMA. 93config B43_BCMA_PIO 94 bool 95 depends on B43_BCMA 96 select BCMA_BLOCKIO 97 default y 98 99config B43_PIO 100 bool 101 depends on B43 102 select SSB_BLOCKIO 103 default y 104 105config B43_PHY_N 106 bool "Support for 802.11n (N-PHY) devices (EXPERIMENTAL)" 107 depends on B43 && EXPERIMENTAL 108 ---help--- 109 Support for the N-PHY. 110 111 This enables support for devices with N-PHY. 112 113 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. 115 116config B43_PHY_LP 117 bool "Support for low-power (LP-PHY) devices (EXPERIMENTAL)" 118 depends on B43 && EXPERIMENTAL 119 default y 120 ---help--- 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). 125 126config B43_PHY_HT 127 bool "Support for HT-PHY devices (BROKEN)" 128 depends on B43 && BROKEN 129 ---help--- 130 Support for the HT-PHY. 131 132 Say N, this is BROKEN and crashes driver. 133 134config B43_PHY_LCN 135 bool "Support for LCN-PHY devices (BROKEN)" 136 depends on B43 && BROKEN 137 ---help--- 138 Support for the LCN-PHY. 139 140 Say N, this is BROKEN and crashes driver. 141 142# This config option automatically enables b43 LEDS support, 143# if it's possible. 144config B43_LEDS 145 bool 146 depends on B43 && MAC80211_LEDS && (LEDS_CLASS = y || LEDS_CLASS = B43) 147 default y 148 149# This config option automatically enables b43 HW-RNG support, 150# if the HW-RNG core is enabled. 151config B43_HWRNG 152 bool 153 depends on B43 && (HW_RANDOM = y || HW_RANDOM = B43) 154 default y 155 156config B43_DEBUG 157 bool "Broadcom 43xx debugging" 158 depends on B43 159 ---help--- 160 Broadcom 43xx debugging. 161 162 This adds additional runtime sanity checks and statistics to the driver. 163 These checks and statistics might me expensive and hurt runtime performance 164 of your system. 165 This also adds the b43 debugfs interface. 166 167 Do not enable this, unless you are debugging the driver. 168 169 Say N, if you are a distributor or user building a release kernel 170 for production use. 171 Only say Y, if you are debugging a problem in the b43 driver sourcecode. 172 173config B43_FORCE_PIO 174 bool "Force usage of PIO instead of DMA" 175 depends on B43 && B43_DEBUG 176 ---help--- 177 This will disable DMA and always enable PIO instead. 178 179 Say N! 180 This is only for debugging the PIO engine code. You do 181 _NOT_ want to enable this.
