Subject: [PATCH v5 0/4] SFH: Add Support for AMD Sensor Fusion Hub
From: Sandeep Singh <sandeep.singh@....com>
AMD SFH(Sensor Fusion Hub) is HID based driver.SFH FW
is part of MP2 processor (MP2 which is an ARM® Cortex-M4
core based co-processor to x86) 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(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.
