Synaptics RMI4 Support
|
|
======================
|
|
|
|
Introduction
|
|
------------
|
|
|
|
This plugin updates integrated Synaptics RMI4 devices, typically touchpads.
|
|
|
|
GUID Generation
|
|
---------------
|
|
|
|
The HID DeviceInstanceId values are used, e.g. `HIDRAW\VEN_06CB&DEV_4875`.
|
|
|
|
These devices also use custom GUID values constructed using the board ID, e.g.
|
|
|
|
* `SYNAPTICS_RMI\TM3038-002`
|
|
* `SYNAPTICS_RMI\TM3038`
|
|
|
|
|
|
Vendor ID Security
|
|
------------------
|
|
|
|
The vendor ID is set from the udev vendor, in this instance set to `HIDRAW:0x06CB`
|
|
|
|
Firmware Format
|
|
---------------
|
|
|
|
The daemon will decompress the cabinet archive and extract a firmware blob in
|
|
a proprietary (but docucumented) file format.
|
|
|
|
This plugin supports the following protocol ID:
|
|
|
|
* com.synaptics.rmi
|
|
|
|
External interface access
|
|
-------------------------
|
|
This plugin requires ioctl access to `HIDIOCSFEATURE` and `HIDIOCGFEATURE`.
