SFH FW is part of MP2 processor and it runs on MP2 where in driver resides on X86. The driver functionalities are divided into three parts:- 1: amd-mp2-pcie:- This module will communicate with MP2 FW and provide that data into DRAM. 2: Client driver :- This part for driver will use dram data and convert that data into HID format based on HID reports. 3: Transport driver :- This part of driver will communicate with HID core. Communication between devices and HID core is mostly done via HID reports In terms of architecture it is much more reassembles like ISH. However the major difference is all The hid reports are generated as part of kernel driver. AMD SFH driver has taken reference from ISH in terms of design and functionalities at fewer location. AMD sensor fusion Hub is part of a SOC starting from Ryzen based platforms. The solution is working well on windows OS in several OEM products. AMD SFH uses HID over PCIe bus.
