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.

menu "Debugging Options"
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.
config IWLWIFI_DEBUGFS
bool "iwlwifi debugfs support"
depends on MAC80211_DEBUGFS
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.

config IWLMEI
tristate "Intel Management Engine communication over WLAN"
depends on INTEL_MEI
depends on PM
depends on CFG80211
help
Enables the iwlmei kernel module.
CSME stands for Converged Security and Management Engine. It is a CPU
on the chipset and runs a dedicated firmware. AMT (Active Management
Technology) is one of the applications that run on that CPU. AMT
allows to control the platform remotely.
This kernel module allows to communicate with the Intel Management
Engine over Wifi. This is supported starting from Tiger Lake
platforms and has been tested on 9260 devices only.
If AMT is configured not to use the wireless device, this module is
harmless (and useless).
Enabling this option on a platform that has a different device and
has Wireless enabled on AMT can prevent WiFi from working correctly.

If unsure, say N.
