Dynamically control the log verbosity with a module parameter. This enables us to dynamically enable debugging messages (or disable info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose. This increases the module size by about 3k. But in practice it reduces the module size for the user, because some distributions ship the b43 module with CONFIG_B43_DEBUG set, which increases the module by about 15k. So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG. There is no reason to keep it in a production-release kernel. So we have a net reduction in size by about 12k. This patch also adds a printk of the wireless core revision, so people don't have to enable SSB debugging to get the wireless core revision.

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

Broadcom 43xx PCMCIA device support.

Support for 16bit PCMCIA devices.
|
|
Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
|
|
devices, but 32bit CardBUS devices. CardBUS devices are supported
|
|
out of the box by b43.
|
|
|

With this config option you can drive b43 cards in
|
|
CompactFlash formfactor in a PCMCIA adaptor.
|
|
CF b43 cards can sometimes be found in handheld PCs.

It's safe to select Y here, even if you don't have a B43 PCMCIA device.

Broadcom 43xx debugging.

|
|
|
This adds additional runtime sanity checks and statistics to the driver.
|
|
These checks and statistics might me expensive and hurt runtime performance
|
|
of your system.
|
|
This also adds the b43 debugfs interface.
|
|
|
|
Do not enable this, unless you are debugging the driver.
|
|
|
|
Say N, if you are a distributor or user building a release kernel
|
|
for production use.
|
|
Only say Y, if you are debugging a problem in the b43 driver sourcecode.
|

This will disable DMA and always enable PIO instead.

|
Say N!
|

This is only for debugging the PIO engine code. You do
|
|
_NOT_ want to enable this.
