Subject: [PATCH v2 0/4] SFH: Add Support for AMD Sensor Fusion Hub
Date: Wed, 29 Jan 2020 09:57:22 +0530 [thread overview]
Message-ID: <1580272046-32101-1-git-send-email-Sandeep.Singh@amd.com> (raw)
From: Sandeep Singh <sandeep.singh@amd.com>
AMD SFH is HID based driver. 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.
Sandeep Singh (4):
SFH: Add maintainer list and documentation for AMD SFH based on HID
framework
SFH: PCI driver to add support of AMD sensor fusion Hub using HID
framework
SFH: Transport Driver to add support of AMD sensor fusion Hub (SFH)
SFH: Create HID report to Enable support of AMD sensor fusion Hub
(SFH)
