The HP M2xfd monitors use GenesysLogic GL3523 USB Hub and provides their
own firmwares. Furthermore, HP uses the same VID/PID for other USB Hubs
products, with a different public-key; the HP M24fd and M27fd use
different public-key.
This appends the public-key to the instance-id string to make the
distinction between all the HP USB Hubs, and prevents to install a
firmware with the wrong public-key.
Genesys Logic uses the same VID/PID for its USB Hubs products, whatever
the chip underneath (GL3523, GL3590...). For example, Genesys Logic
USB2.0 Hub uses 05E3/0610; and Genesys Logic USB3.1 Hub uses 05E3/0612.
The manufacturers may reuse the Genesys Logic VID/PID for its products
or may use its own VID such as HP (03F0).
The genesys plugin supports upgrading GL3523 USB and GL3590 USB2.0 Hubs
for now (the latter is not tested).
The quirk file limits the support to HP Hubs only; and the plugin will
allow upgrade Hub with genuine Genesys Logic VID/PID in the future by
adding the following lines to the quirk file:
[USB\VID_05E3&PID_0610]
Plugin = genesys
However, this change in the quirk file will report the errors below for
the Hub with IC that are not supported:
04:26:40:0325 FuEngine failed to add device usb:01:00:01: Unsupported IC GL3521-22
04:26:40:0344 FuEngine failed to add device usb:01:00:01: Unsupported IC GL3521-22
Note: This may be true already if HP uses Hubs with IC that are not
unsupported.
This change returns the error FWUPD_ERROR_NOT_SUPPORTED instead to fail
silently.
The plugin gets the panel-type (i.e. hardware revision) as the firmware
version.
This gets the real firmware version, and appends the panel-type to the
instance-id string as the blobs are specific to panel-types.
The Special Protect Sector structure is 24-bit long.
This replaces the 32-bit integer in union that makes the structure
8-bits too big by an array of 3-bytes.
Provide a device instance builder that allows plugins to easily
create multiple instance IDs based on parent attributes.
Also fix a lot of the instance ID orders, so that we add more generic
IDs first, and more specific IDs after.
tristate features will automatically disable if dependencies marked
as required are missing.
Packagers can manually override using `auto_features`.
