  7. b43 is a driver for the Broadcom 43xx series wireless devices.
  8. Check "lspci" for something like
  9. "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
  10. to determine whether you own such a device.
  11. This driver supports the new BCM43xx IEEE 802.11G devices, but not
  12. the old IEEE 802.11B devices. Old devices are supported by
  13. the b43legacy driver.
  14. Note that this has nothing to do with the standard that your AccessPoint
  15. supports (A, B, G or a combination).
  16. IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
  17. It is safe to include both b43 and b43legacy as the underlying glue
  18. layer will automatically load the correct version for your device.
  19. This driver uses V4 firmware, which must be installed separately using
  20. b43-fwcutter.
  21. This driver can be built as a module (recommended) that will be called "b43".
  22. If unsure, say M.
  23. config B43_BCMA

  47. select SSB_PCMCIAHOST
  48. ---help---
  49. Broadcom 43xx PCMCIA device support.
  50. Support for 16bit PCMCIA devices.
  51. Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
  52. devices, but 32bit CardBUS devices. CardBUS devices are supported
  53. out of the box by b43.
  54. With this config option you can drive b43 cards in
  55. CompactFlash formfactor in a PCMCIA adaptor.
  56. CF b43 cards can sometimes be found in handheld PCs.
  57. It's safe to select Y here, even if you don't have a B43 PCMCIA device.
  58. If unsure, say N.
  59. config B43_SDIO
  60. bool "Broadcom 43xx SDIO device support (EXPERIMENTAL)"
  61. depends on B43 && SSB_SDIOHOST_POSSIBLE && EXPERIMENTAL
  62. select SSB_SDIOHOST
  63. ---help---
  64. Broadcom 43xx device support for Soft-MAC SDIO devices.
  65. With this config option you can drive Soft-MAC b43 cards with a
  66. Secure Digital I/O interface.
  67. This includes the WLAN daughter card found on the Nintendo Wii
  68. video game console.
  69. Note that this does not support Broadcom 43xx Full-MAC devices.
  70. It's safe to select Y here, even if you don't have a B43 SDIO device.
  71. If unsure, say N.
  72. #Data transfers to the device via PIO. We want it as a fallback even
  73. # if we can do DMA.
  74. config B43_PIO

  81. depends on B43 && EXPERIMENTAL
  82. ---help---
  83. Support for the N-PHY.
  84. This enables support for devices with N-PHY.
  85. Say N if you expect high stability and performance. Saying Y will not
  86. affect other devices support and may provide support for basic needs.
  87. config B43_PHY_LP
  88. bool "Support for low-power (LP-PHY) devices (EXPERIMENTAL)"
  89. depends on B43 && EXPERIMENTAL
  90. default y
  91. ---help---
  92. Support for the LP-PHY.
  93. The LP-PHY is a low-power PHY built into some notebooks
  94. and embedded devices. It supports 802.11a/g
  95. (802.11a support is optional, and currently disabled).
  96. config B43_PHY_HT
  97. bool "Support for HT-PHY devices (BROKEN)"
  98. depends on B43 && BROKEN
  99. ---help---
  100. Support for the HT-PHY.
  101. Say N, this is BROKEN and crashes driver.

  117. ---help---
  118. Broadcom 43xx debugging.
  119. This adds additional runtime sanity checks and statistics to the driver.
  120. These checks and statistics might me expensive and hurt runtime performance
  121. of your system.
  122. This also adds the b43 debugfs interface.
  123. Do not enable this, unless you are debugging the driver.
  124. Say N, if you are a distributor or user building a release kernel
  125. for production use.
  126. Only say Y, if you are debugging a problem in the b43 driver sourcecode.
  127. config B43_FORCE_PIO
  128. bool "Force usage of PIO instead of DMA"
  129. depends on B43 && B43_DEBUG
  130. ---help---
  131. This will disable DMA and always enable PIO instead.
  132. Say N!
  133. This is only for debugging the PIO engine code. You do
  134. _NOT_ want to enable this.
