Richard Hughes e87fc05ab9 Speed up the daemon startup by ~2% by doing dlsym much less 
We were calling g_module_symbol() 2703 times, which is actually more
expensive than you'd think.

It also means the plugins are actually what we tell people they are:
A set of vfuncs that get run. The reality before that they were dlsym'd
functions that get called at pretty random times.

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.
