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

96	bool "Enable full debugging output in the iwlwifi driver"
97	help
98	  This option will enable debug tracing output for the iwlwifi drivers
99
100	  This will result in the kernel module being ~100k larger.  You can
101	  control which debug output is sent to the kernel log by setting the
102	  value in
103
104		/sys/module/iwlwifi/parameters/debug
105
106	  This entry will only exist if this option is enabled.
107
108	  To set a value, simply echo an 8-byte hex value to the same file:
109
110		  % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
111
112	  You can find the list of debug mask values in:
113		  drivers/net/wireless/iwlwifi/iwl-debug.h
114
115	  If this is your first time using this driver, you should say Y here
116	  as the debug information can assist others in helping you resolve
117	  any problems you may encounter.

132	  Say Y here to trace all commands, including TX frames and IO
133	  accesses, sent to the device. If you say yes, iwlwifi will
134	  register with the ftrace framework for event tracing and dump
135	  all this information to the ringbuffer, you may need to
136	  increase the ringbuffer size. See the ftrace documentation
137	  for more information.
138
139	  When tracing is not enabled, this option still has some
140	  (though rather small) overhead.
141
142	  If unsure, say Y so we can help you better when problems
143	  occur.

156
157	  CSME stands for Converged Security and Management Engine. It is a CPU
158	  on the chipset and runs a dedicated firmware. AMT (Active Management
159	  Technology) is one of the applications that run on that CPU. AMT
160	  allows to control the platform remotely.
161
162	  This kernel module allows to communicate with the Intel Management
163	  Engine over Wifi. This is supported starting from Tiger Lake
164	  platforms and has been tested on 9260 devices only.
165	  If AMT is configured not to use the wireless device, this module is
166	  harmless (and useless).
167	  Enabling this option on a platform that has a different device and
168	  has Wireless enabled on AMT can prevent WiFi from working correctly.
