Richard Hughes d99f86023f trivial: Add getters to FuChunk 
At the moment FuChunks are sometimes mutable, and sometimes immutable, and it's
all a bit too low level for comfort.

Before we can do any kind of optimisation or verification we need plugins to
stop reading directly from the C structure. The aim here is to make FuChunk
optionally mutable without making assumptions about the memory model, and also
to be able to introspect it for the docs.

VIA Support

Introduction

This plugin is used to update USB hubs from VIA.

Firmware Format

The daemon will decompress the cabinet archive and extract a firmware blob in an undisclosed binary file format.

This plugin supports the following protocol ID:

  • com.vli.i2c
  • com.vli.pd
  • com.vli.usbhub

GUID Generation

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

  • USB\VID_17EF&PID_3083&REV_0001
  • USB\VID_17EF&PID_3083
  • USB\VID_17EF

All VLI devices also use custom GUID values for the device type, e.g.

  • USB\VID_17EF&PID_3083&DEV_VL812B3

These devices also use custom GUID values for the SPI flash configuration, e.g.

  • VLI_USBHUB\SPI_37303840
  • VLI_USBHUB\SPI_3730
  • VLI_USBHUB\SPI_37

Optional PD child devices sharing the SPI flash use two extra GUIDs, e.g.

  • USB\VID_17EF&PID_3083&DEV_VL102
  • USB\VID_17EF&PID_3083&APP_26

Optional I²C child devices use just one extra GUID, e.g.

  • USB\VID_17EF&PID_3083&I2C_MSP430
  • USB\VID_17EF&PID_3083&I2C_PS186

Vendor ID Security

The vendor ID is set from the USB vendor, for example set to USB:0x2109

Quirk Use

This plugin uses the following plugin-specific quirks:

Quirk Description Minimum fwupd version
DeviceKind Device kind, e.g. VL102 1.3.7
SpiAutoDetect SPI autodetect (default 0x1) 1.3.7
SpiCmdChipErase Flash command to erase chip 1.3.3
SpiCmdChipErase Flash command to erase sector 1.3.3
SpiCmdReadId Flash command to read the ID 1.3.3
SpiCmdReadIdSz Size of the ReadId response 1.3.3

The SpiCmdReadId and SpiCmdReadIdSz quirks have to be assigned to the device instance attribute, rather then the flash part as the ID is required to query the other flash chip parameters. For example:

[DeviceInstanceId=USB\VID_2109&PID_0210]
Plugin = vli
GType = FuVliUsbhubDevice
SpiCmdReadId = 0xf8
SpiCmdReadIdSz = 4

# W3IRDFLASHxxx
[Guid=VLI_USBHUB\\SPI_37303840]
SpiCmdChipErase = 0xc7
SpiCmdSectorErase = 0x20

External interface access

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