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: Intel GSC — Graphics System Controller

Introduction

This plugin is used to update the Intel graphics system controller via the Intel Management Engine.

Firmware Format

There are two firmware formats in use:

  • $FPT with children FuIfwiFptFirmware, where the FW_DATA_IMAGE is a FuIfwiCpdFirmware
  • A linear array of FuOpromFirmware images, each with a FuIfwiCpdFirmware

This plugin supports the following protocol ID:

  • com.intel.gsc

GUID Generation

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

  • MEI\VID_8086&DEV_4905

They also define custom per-part PCI IDs such as:

  • MEI\VID_8086&DEV_4905&PART_FWCODE
  • MEI\VID_8086&DEV_4905&PART_FWDATA
  • MEI\VID_8086&DEV_4905&PART_OPROMCODE
  • MEI\VID_8086&DEV_4905&PART_OPROMDATA

Vendor ID Security

The vendor ID is set from the PCI vendor, in this instance set to MEI:0x8086

External Interface Access

This plugin requires read/write access to /dev/mei*.
