AMD SFH(Sensor Fusion Hub) is HID based driver.SFH FW is part of MP2
processor (MP2 which is an ARM core connected to x86 for processing
sensor data) and it runs on MP2 where in the driver resides on X86.
The driver functionalities are divided into three parts:-
1: amd-mp2-pcie:- This part of the module will communicate with MP2
firmware. MP2 which is exposed as a PCI device to the
X86, uses mailboxes to talk to MP2 firmware to
send/receive commands.
2: Client Layer:- This part of the driver will use DRAM data and convert
the data into HID format based on HID reports.
3: Transport layer :- This part of the driver the will communicate with HID
core.Communication between devices and HID core is
mostly done via HID reports
In terms of architecture, it resembles like ISH (Intel Integrated Sensor
Hub). However the major difference is all the hid reports are generated
as part of the kernel driver.
AMD SFH is integrated as a part of SoC, starting from 17h family of
processors. The solution is working well on several OEM products.
AMD SFH uses HID over PCIe bus.

From: Sandeep Singh <[email protected]>
Communication between HID devices and HID core is mostly done
via HID reports. HID reports are formed based on the data received
from the PCI layer into the HID report descriptors.

2.25.1
From: Sandeep Singh <[email protected]>
To support AMD Sensor Fusion Hub (SFH) via the HID client's we need to
register the client with the HID framework. Here we mostly address on
how to register the client with the framework and define the interfaces
for communication.

+AMD Sensor Fusion Hub
+=====================
+AMD Sensor Fusion Hub (SFH) is part of an SOC starting from Ryzen based platforms.
+The solution is working well on several OEM products. AMD SFH uses HID over PCIe bus.
+In terms of architecture it resembles ISH, however the major difference is all
+the HID reports are generated as part of the kernel driver.
+
+1. Block Diagram
+================
+
+::
+
+ ---------------------------------
+ | HID User Space Applications |
+ - -------------------------------
+
+ ---------------------------------------------
+ ---------------------------------
+ | HID Core |
+ ---------------------------------
+
+ ---------------------------------
+ | AMD HID Transport |

+ --------------------------------
+ OS
+ ---------------------------------------------
+ Hardware + Firmware
+ --------------------------------
+ | SFH MP2 Processor |
+ --------------------------------
+
+
+AMD HID Transport Layer
+-----------------------
+AMD SFH transport is also implemented as a bus. Each client application executing in the AMD MP2 is
+registered as a device on this bus. Here: MP2 which is an ARM core connected to x86 for processing
+sensor data. The layer, which binds each device (AMD SFH HID driver) identifies the device type and
+registers with the hid core. Transport layer attach a constant "struct hid_ll_driver" object with
+each device. Once a device is registered with HID core, the callbacks provided via this struct are
+used by HID core to communicate with the device. AMD HID Transport layer implements the synchronous calls.
+
+AMD HID Client Layer
+--------------------
+This layer is responsible to implement HID request and descriptors. As firmware is OS agnostic, HID
+client layer fills the HID request structure and descriptors. HID client layer is complex as it is
+interface between MP2 PCIe layer and HID. HID client layer initialized the MP2 PCIe layer and holds
+the instance of MP2 layer. It identifies the number of sensors connected using MP2-PCIe layer. Base
+on that allocates the DRAM address for each and every sensor and pass it to MP2-PCIe driver.On
+enumeration of each the sensor, client layer fills the HID Descriptor structure and HID input repor
+structure. HID Feature report structure is optional. The report descriptor structure varies from
+sensor to sensor.
+
+AMD MP2 PCIe layer
+------------------
+MP2 PCIe Layer is responsible for making all transactions with the firmware over PCIe.
+The connection establishment between firmware and PCIe happens here.
+
+The communication between X86 and MP2 is split into three parts.
+1. Command transfer via the C2P mailbox registers.
+2. Data transfer via DRAM.
+3. Supported sensor info via P2C registers.
+
+Commands are sent to MP2 using C2P Mailbox registers. Writing into C2P Message registers generate
+interrupt to MP2. The client layer allocates the physical memory and the same is sent to MP2 via
+the PCI layer. MP2 firmware writes the command output to the access DRAM memory which the client
+layer has allocated. Firmware always writes minimum of 32 bytes into DRAM. So as a protocol driver
+shall allocate minimum of 32 bytes DRAM space.

I have now applied the series to hid.git#for-5.11/amd-sfh-hid. Thanks for
all the efforts in tidying this up,

Thank you Jiri and all the community folks for improving this series
with your feedback. I have sent a minor fix which was reported recently
on top of
your branch hid.git#for-5.11/amd-sfh-hid. Can you please review and
apply it?

I do not know where something went wrong here, but it seems that
the git commit 302f0dad8c97 ("SFH: Add maintainers and
documentation for AMD SFH based on HID framework") on next-20201030
dropped the addition of the rst file compared to this patch v8 here.
See: git show --stat 302f0dad8c97a11abcf145ff3c70

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:
warning: no file matches F: Documentation/hid/amd-sfh*
Just that you know...

Thanks for spotting this, that was me fat-fingering conflict resolution.
I've now pushed out a fix.
