0030 This driver uses the kernel's mac80211 subsystem.
0031
0032 In order to use this driver, you will need a firmware
0033 image for it. You can obtain the microcode from:
0034
0035 <https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi>.
0036
0037 The firmware is typically installed in /lib/firmware. You can
0038 look in the hotplug script /etc/hotplug/firmware.agent to
0039 determine which directory FIRMWARE_DIR is set to when the script
0040 runs.
0041
0042 If you want to compile the driver as a module ( = code which can be
0043 inserted in and removed from the running kernel whenever you want),
0044 say M here and read <file:Documentation/kbuild/modules.rst>. The
0045 module will be called iwlwifi.

0086 bool "Enable full debugging output in the iwlwifi driver"
0087 help
0088 This option will enable debug tracing output for the iwlwifi drivers
0089
0090 This will result in the kernel module being ~100k larger. You can
0091 control which debug output is sent to the kernel log by setting the
0092 value in
0093
0094 /sys/module/iwlwifi/parameters/debug
0095
0096 This entry will only exist if this option is enabled.
0097
0098 To set a value, simply echo an 8-byte hex value to the same file:
0099
0100 % echo 0x43fff > /sys/module/iwlwifi/parameters/debug
0101
0102 You can find the list of debug mask values in:
0103 drivers/net/wireless/iwlwifi/iwl-debug.h
0104
0105 If this is your first time using this driver, you should say Y here
0106 as the debug information can assist others in helping you resolve
0107 any problems you may encounter.

0121 help
0122 Say Y here to trace all commands, including TX frames and IO
0123 accesses, sent to the device. If you say yes, iwlwifi will
0124 register with the ftrace framework for event tracing and dump
0125 all this information to the ringbuffer, you may need to
0126 increase the ringbuffer size. See the ftrace documentation
0127 for more information.
0128
0129 When tracing is not enabled, this option still has some
0130 (though rather small) overhead.
0131
0132 If unsure, say Y so we can help you better when problems
0133 occur.

0146
0147 CSME stands for Converged Security and Management Engine. It is a CPU
0148 on the chipset and runs a dedicated firmware. AMT (Active Management
0149 Technology) is one of the applications that run on that CPU. AMT
0150 allows to control the platform remotely.
0151
0152 This kernel module allows to communicate with the Intel Management
0153 Engine over Wifi. This is supported starting from Tiger Lake
0154 platforms and has been tested on 9260 devices only.
0155 If AMT is configured not to use the wireless device, this module is
0156 harmless (and useless).
0157 Enabling this option on a platform that has a different device and
0158 has Wireless enabled on AMT can prevent WiFi from working correctly.
