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.

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

133	default y
134	help
135	  Say Y here to trace all commands, including TX frames and IO
136	  accesses, sent to the device. If you say yes, iwlwifi will
137	  register with the ftrace framework for event tracing and dump
138	  all this information to the ringbuffer, you may need to
139	  increase the ringbuffer size. See the ftrace documentation
140	  for more information.
141
142	  When tracing is not enabled, this option still has some
143	  (though rather small) overhead.
144

146	  occur.

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