30 This driver uses the kernel's mac80211 subsystem.
32 In order to use this driver, you will need a firmware
33 image for it. You can obtain the microcode from:
35 <https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi>.
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
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.

83 menu "Debugging Options"
86 bool "Enable full debugging output in the iwlwifi driver"
88 This option will enable debug tracing output for the iwlwifi drivers
90 This will result in the kernel module being ~100k larger. You can
91 control which debug output is sent to the kernel log by setting the
94 /sys/module/iwlwifi/parameters/debug
96 This entry will only exist if this option is enabled.
98 To set a value, simply echo an 8-byte hex value to the same file:
100 % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
102 You can find the list of debug mask values in:
103 drivers/net/wireless/iwlwifi/iwl-debug.h
105 If this is your first time using this driver, you should say Y here
106 as the debug information can assist others in helping you resolve
107 any problems you may encounter.
109 config IWLWIFI_DEBUGFS
110 bool "iwlwifi debugfs support"
111 depends on MAC80211_DEBUGFS
113 Enable creation of debugfs files for the iwlwifi drivers. This
114 is a low-impact option that allows getting insight into the
115 driver's state at runtime.
117 config IWLWIFI_DEVICE_TRACING
118 bool "iwlwifi device access tracing"
119 depends on EVENT_TRACING
122 Say Y here to trace all commands, including TX frames and IO
123 accesses, sent to the device. If you say yes, iwlwifi will
124 register with the ftrace framework for event tracing and dump
125 all this information to the ringbuffer, you may need to
126 increase the ringbuffer size. See the ftrace documentation
127 for more information.
129 When tracing is not enabled, this option still has some
130 (though rather small) overhead.
132 If unsure, say Y so we can help you better when problems
139 tristate "Intel Management Engine communication over WLAN"
143 Enables the iwlmei kernel module.
145 CSME stands for Converged Security and Management Engine. It is a CPU
146 on the chipset and runs a dedicated firmware. AMT (Active Management
147 Technology) is one of the applications that run on that CPU. AMT
148 allows to control the platform remotely.
150 This kernel module allows to communicate with the Intel Management
151 Engine over Wifi. This is supported starting from Tiger Lake
152 platforms and has been tested on 9260 devices only.
153 If AMT is configured not to use the wireless device, this module is
154 harmless (and useless).
155 Enabling this option on a platform that has a different device and
156 has Wireless enabled on AMT can prevent WiFi from working correctly.
