It is a CPU158 on the chipset and runs a dedicated firmware. AMT (Active Management159 Technology) is one of the applications that run on that CPU. AMT160 allows to control the platform remotely.161 162 This kernel module allows to communicate with the Intel Management163 Engine over Wifi. This is supported starting from Tiger Lake164 platforms and has been tested on 9260 devices only.165 If AMT is configured not to use the wireless device, this module is166 harmless (and useless).167 Enabling this option on a platform that has a different device and168 has Wireless enabled on AMT can prevent WiFi from working correctly.169 170 For more information see171 <https://software.intel.com/en-us/manageability/>172 173 If unsure, say N.174
