This driver uses the kernel's mac80211 subsystem.
|
|
In order to use this driver, you will need a firmware
|
image for it. You can obtain the microcode from:
|
|
<https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi>.
|
|
The firmware is typically installed in /lib/firmware. You can
|
look in the hotplug script /etc/hotplug/firmware.agent to
|
determine which directory FIRMWARE_DIR is set to when the script
|
runs.
|
|
If you want to compile the driver as a module ( = code which can be
|
inserted in and removed from the running kernel whenever you want),
|
say M here and read <file:Documentation/kbuild/modules.rst>. The
|
module will be called iwlwifi.

help

Say Y here to enable default bcast filtering configuration.
|
|
Enabling broadcast filtering will drop any incoming wireless
|
broadcast frames, except some very specific predefined
|
patterns (e.g. incoming arp requests).
|
|
If unsure, don't enable this option, as some programs might
|
expect incoming broadcasts for their normal operations.

|
|
config IWLWIFI_DEBUG
|
bool "Enable full debugging output in the iwlwifi driver"
|
help
|
This option will enable debug tracing output for the iwlwifi drivers
|
|
This will result in the kernel module being ~100k larger. You can
|
control which debug output is sent to the kernel log by setting the
|
value in
|
|
/sys/module/iwlwifi/parameters/debug
|
|
This entry will only exist if this option is enabled.
|
|
To set a value, simply echo an 8-byte hex value to the same file:
|
|
% echo 0x43fff > /sys/module/iwlwifi/parameters/debug
|
|
You can find the list of debug mask values in:
|
drivers/net/wireless/iwlwifi/iwl-debug.h
|
|
If this is your first time using this driver, you should say Y here
|
as the debug information can assist others in helping you resolve
|
any problems you may encounter.

help

Enable creation of debugfs files for the iwlwifi drivers. This
|
is a low-impact option that allows getting insight into the
|
driver's state at runtime.

config IWLWIFI_DEVICE_TRACING

bool "iwlwifi device access tracing"
|
depends on EVENT_TRACING
|
default y
|
help
|
Say Y here to trace all commands, including TX frames and IO
|
accesses, sent to the device. If you say yes, iwlwifi will
|
register with the ftrace framework for event tracing and dump
|
all this information to the ringbuffer, you may need to
|
increase the ringbuffer size. See the ftrace documentation
|
for more information.
|
|
When tracing is not enabled, this option still has some
|
(though rather small) overhead.
|
|
If unsure, say Y so we can help you better when problems
|
occur.
