Richard Hughes 40cd18fa97 Allow using a per-device global percentage completion 
It's actually quite hard to build a front-end for fwupd at the moment
as you're never sure when the progress bar is going to zip back to 0%
and start all over again. Some plugins go 0..100% for write, others
go 0..100% for erase, then again for write, then *again* for verify.

By creating a helper object we can easily split up the progress of the
specific task, e.g. write_firmware().

We can encode at the plugin level "the erase takes 50% of the time, the
write takes 40% and the read takes 10%". This means we can have a
progressbar which goes up just once at a consistent speed.

Analogix

Introduction

This plugin can flash the firmware of some Analogix billboard devices.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in a Intel Hex file format. The resulting binary image is either:

  • OCM section only
  • CUSTOM section only
  • Multiple sections excluded CUSTOM -- at fixed offsets and sizes

This plugin supports the following protocol ID:

  • com.analogix.bb

GUID Generation

These devices use the standard USB DeviceInstanceId values, e.g.

  • USB\VID_1F29&PID_7518

Update Behavior

The device is updated at runtime using USB control transfers.

Vendor ID Security

The vendor ID is set from the USB vendor. The list of USB VIDs used is:

  • USB:0x1F29

External Interface Access

This plugin requires read/write access to /dev/bus/usb.
