30e705c121SKalle Valo	  This driver uses the kernel's mac80211 subsystem.
31e705c121SKalle Valo
32e705c121SKalle Valo	  In order to use this driver, you will need a firmware
33e705c121SKalle Valo	  image for it. You can obtain the microcode from:
34e705c121SKalle Valo
35e00c6d8dSFlavio Suligoi	          <https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi>.
36e705c121SKalle Valo
37e705c121SKalle Valo	  The firmware is typically installed in /lib/firmware. You can
38e705c121SKalle Valo	  look in the hotplug script /etc/hotplug/firmware.agent to
39e705c121SKalle Valo	  determine which directory FIRMWARE_DIR is set to when the script
40e705c121SKalle Valo	  runs.
41e705c121SKalle Valo
42e705c121SKalle Valo	  If you want to compile the driver as a module ( = code which can be
43e705c121SKalle Valo	  inserted in and removed from the running kernel whenever you want),
44cd238effSMauro Carvalho Chehab	  say M here and read <file:Documentation/kbuild/modules.rst>.  The
45e705c121SKalle Valo	  module will be called iwlwifi.

125e705c121SKalle Valo	  all this information to the ringbuffer, you may need to
126e705c121SKalle Valo	  increase the ringbuffer size. See the ftrace documentation

146977df8bdSArnd Bergmann
147977df8bdSArnd Bergmann	  CSME stands for Converged Security and Management Engine. It is a CPU
148977df8bdSArnd Bergmann	  on the chipset and runs a dedicated firmware. AMT (Active Management
149977df8bdSArnd Bergmann	  Technology) is one of the applications that run on that CPU. AMT
150977df8bdSArnd Bergmann	  allows to control the platform remotely.
151977df8bdSArnd Bergmann
152977df8bdSArnd Bergmann	  This kernel module allows to communicate with the Intel Management
153977df8bdSArnd Bergmann	  Engine over Wifi. This is supported starting from Tiger Lake
154977df8bdSArnd Bergmann	  platforms and has been tested on 9260 devices only.
155977df8bdSArnd Bergmann	  If AMT is configured not to use the wireless device, this module is
156977df8bdSArnd Bergmann	  harmless (and useless).
157977df8bdSArnd Bergmann	  Enabling this option on a platform that has a different device and
158977df8bdSArnd Bergmann	  has Wireless enabled on AMT can prevent WiFi from working correctly.
