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

99         Say Y here to enable runtime power management for PCIe
100         devices.  If enabled, the device will go into low power mode
101         when idle for a short period of time, allowing for improved
102         power saving during runtime. Note that this feature requires
103         a tight integration with the platform. It is not recommended
104         to enable this feature without proper validation with the
105         specific target platform.

112	bool "Enable full debugging output in the iwlwifi driver"
113	---help---
114	  This option will enable debug tracing output for the iwlwifi drivers
115
116	  This will result in the kernel module being ~100k larger.  You can
117	  control which debug output is sent to the kernel log by setting the
118	  value in
119
120		/sys/module/iwlwifi/parameters/debug
121
122	  This entry will only exist if this option is enabled.
123
124	  To set a value, simply echo an 8-byte hex value to the same file:
125
126		  % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
127
128	  You can find the list of debug mask values in:
129		  drivers/net/wireless/iwlwifi/iwl-debug.h
130
131	  If this is your first time using this driver, you should say Y here
132	  as the debug information can assist others in helping you resolve
133	  any problems you may encounter.

140	  is a low-impact option that allows getting insight into the
141	  driver's state at runtime.

143config IWLWIFI_DEVICE_TRACING
144	bool "iwlwifi device access tracing"
145	depends on EVENT_TRACING
146	default y
147	help
148	  Say Y here to trace all commands, including TX frames and IO
149	  accesses, sent to the device. If you say yes, iwlwifi will
150	  register with the ftrace framework for event tracing and dump
151	  all this information to the ringbuffer, you may need to
152	  increase the ringbuffer size. See the ftrace documentation
153	  for more information.
154
155	  When tracing is not enabled, this option still has some
156	  (though rather small) overhead.
157
158	  If unsure, say Y so we can help you better when problems
159	  occur.
