  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 depends on BROKEN 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.
