It is a CPU 149 on the chipset and runs a dedicated firmware. AMT (Active Management 150 Technology) is one of the applications that run on that CPU. AMT 151 allows to control the platform remotely. 152 153 This kernel module allows to communicate with the Intel Management 154 Engine over Wifi. This is supported starting from Tiger Lake 155 platforms and has been tested on 9260 devices only. 156 If AMT is configured not to use the wireless device, this module is 157 harmless (and useless). 158 Enabling this option on a platform that has a different device and 159 has Wireless enabled on AMT can prevent WiFi from working correctly. 160 161 For more information see 162 <https://software.intel.com/en-us/manageability/> 163 164 If unsure, say N. 165
