Communication between devices and HID core is mostly done via HID reports In terms of architecture it is much more reassembles like ISH(Intel Integrated Sensor Hub). However the major difference is all the hid reports are generated as part of kernel driver. AMD SFH driver taken reference from ISH in terms of design and functionalities at fewer location. AMD sensor fusion Hub is part of a SOC 17h family based platforms. The solution is working well on several OEM products. AMD SFH uses HID over PCIe bus.
