README.md

Synaptics MST

This plugin supports querying and flashing Synaptics MST hubs used in Dell systems and docks.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an unspecified binary file format.

This plugin supports the following protocol ID:

com.synaptics.mst

GUID Generation

These devices use custom GUID values, e.g.

MST-$(device_kind)-$(chip-ID)-$(board-ID)
MST-$(device_kind)-$(board-ID)
MST-$(device_kind)

Please refer to the plugin source for more details about how the GUID is constructed for specific hardware.

Requirements

(Kernel) DP Aux Interface

Kernel 4.6 introduced an DRM DP Aux interface for manipulation of the registers needed to access an MST hub. This patch can be backported to earlier kernels: e94cb37b34

libsmbios

At compilation time and runtime you will need libsmbios_c version 2.3.0 or later

source: https://github.com/dell/libsmbios
rpms: https://apps.fedoraproject.org/packages/libsmbios
debs (Debian): http://tracker.debian.org/pkg/libsmbios
debs (Ubuntu): http://launchpad.net/ubuntu/+source/libsmbios

If you don't want or need this functionality you can use the --disable-dell option.

Usage

Supported devices will be displayed in # fwupdmgr get-devices output.

Here is an example output from a Dell WD15 dock:

Dell WD15/TB16 wired Dock Synaptics VMM3332
  Guid:                 653cd006-5433-57db-8632-0413af4d3fcc
  DeviceID:             MST-1-1-0-0
  Plugin:               synapticsmst
  Flags:                allow-online
  Version:              3.10.002
  Created:              2017-01-13
  Modified:             2017-01-13
  Trusted:              none

Payloads can be flashed just like any other plugin from LVFS.
