  6. This is an experimental driver for the Broadcom 43xx wireless chip,
  7. found in the Apple Airport Extreme and various other devices.
  8. config BCM43XX_DEBUG

  11. default y
  12. ---help---
  13. Broadcom 43xx debugging messages.
  14. Say Y, because the driver is still very experimental and
  15. this will help you get it running.

  30. ---help---
  31. Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
  32. data transfer modes.
  33. The actually used mode is selectable through the module
  34. parameter "pio". If the module parameter is pio=0, DMA is used.
  35. Otherwise PIO is used. DMA is default.
  36. If unsure, choose this option.
  37. config BCM43XX_DMA_MODE
  38. bool "DMA (Direct Memory Access) only"
  39. select BCM43XX_DMA
  40. ---help---
  41. Only include Direct Memory Access (DMA).
  42. This reduces the size of the driver module, by omitting the PIO code.
  43. config BCM43XX_PIO_MODE
  44. bool "PIO (Programmed I/O) only"
  45. select BCM43XX_PIO
  46. ---help---
  47. Only include Programmed I/O (PIO).
  48. This reduces the size of the driver module, by omitting the DMA code.
  49. Please note that PIO transfers are slow (compared to DMA).
  50. Also note that not all devices of the 43xx series support PIO.
  51. The 4306 (Apple Airport Extreme and others) supports PIO, while
  52. the 4318 is known to _not_ support PIO.
  53. Only use PIO, if DMA does not work for you.
