Richard Hughes 99df74f0c2 Add API to wait for a device 
This allows us to ignore all the delays when the device is emulated, with the
idea being to do dozens of device emulations in the CI tests.

Also, do not call fu_progress_sleep() when the device is emulated.

title: Plugin: Fastboot

Introduction

This plugin is used to update hardware that uses the fastboot protocol.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in ZIP file format. Inside the zip file must be all the firmware images for each partition and a manifest file. The partition images can be in any format, but the manifest must be either an Android flashfile.xml format file, or a QFIL partition_nand.xml format file.

For both types, all partitions with a defined image found in the zip file will be updated.

This plugin supports the following protocol ID:

  • com.google.fastboot

GUID Generation

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

  • USB\VID_18D1&PID_4EE0&REV_0001
  • USB\VID_18D1&PID_4EE0
  • USB\VID_18D1

Update Behavior

A fastboot device usually presents in runtime mode (or with no interface), but if the user puts the device into fastboot mode using a physical button it then enumerates with a USB descriptor. On attach the device reboots to runtime mode which may mean the device "goes away".

For this reason the REPLUG_MATCH_GUID internal device flag is used so that the bootloader and runtime modes are treated as the same device.

Quirk Use

This plugin uses the following plugin-specific quirk:

FastbootBlockSize

Block size to use for transfers.

Since: 1.2.2

FastbootOperationDelay

Time in ms to delay after a read or write operation.

Since: 1.7.4

Vendor ID Security

The vendor ID is set from the USB vendor, for example USB:0x18D1

External Interface Access

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