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*.
