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>.

See the ftrace documentation 127 for more information. 128 129 When tracing is not enabled, this option still has some 130 (though rather small) overhead. 131 132 If unsure, say Y so we can help you better when problems 133 occur. 134endmenu 135 136endif 137 138config IWLMEI 139 tristate "Intel Management Engine communication over WLAN" 140 depends on INTEL_MEI 141 depends on PM 142 depends on CFG80211 143 help 144 Enables the iwlmei kernel module. 145 146 CSME stands for Converged Security and Management Engine. It is a CPU 147 on the chipset and runs a dedicated firmware. AMT (Active Management 148 Technology) is one of the applications that run on that CPU. AMT 149 allows to control the platform remotely. 150 151 This kernel module allows to communicate with the Intel Management 152 Engine over Wifi. This is supported starting from Tiger Lake 153 platforms and has been tested on 9260 devices only. 154 If AMT is configured not to use the wireless device, this module is 155 harmless (and useless). 156 Enabling this option on a platform that has a different device and 157 has Wireless enabled on AMT can prevent WiFi from working correctly. 158 159 For more information see 160 <https://software.intel.com/en-us/manageability/> 161 162 If unsure, say N.
