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.

Wacom RAW

Introduction

This plugin updates integrated Wacom AES and EMR devices. They are typically connected using I²C and not USB.

GUID Generation

The HID DeviceInstanceId values are used, e.g. HIDRAW\VEN_056A&DEV_4875.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in Intel HEX file format.

This plugin supports the following protocol ID:

  • com.wacom.raw

Quirk Use

This plugin uses the following plugin-specific quirks:

WacomI2cFlashBlockSize

Block size to transfer firmware.

Since: 1.2.4

WacomI2cFlashBaseAddr

Base address for firmware.

Since: 1.2.4

WacomI2cFlashSize

Maximum size of the firmware zone.

Since: 1.2.4

Update Behavior

The device usually presents in runtime mode, but on detach re-enumerates with a different HIDRAW PID in a bootloader mode. On attach the device re-enumerates back to the runtime mode.

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.

Vendor ID Security

The vendor ID is set from the udev vendor, in this instance set to HIDRAW:0x056A

External Interface Access

This plugin requires ioctl HIDIOCSFEATURE access.
