Richard Hughes eddaed0c11 Allow specifying more than one VendorID for a device 
Asking the user for the UID mapping isn't working very well, as it requires lots
of manual handholding. It also doesn't work very well when the device vendor
does not actually have a PCI ID or if the vendor has split into two entities.

Just use the OUI address as an additional VendorID and match any of the device
IDs against any of the metadata-supplied values.

Dell ESRT Support

Introduction

This allows enabling the BIOS setup option for UEFI capsule updates without manually going into BIOS setup.

GUID Generation

These device uses a hardcoded GUID of 2d47f29b-83a2-4f31-a2e8-63474f4d4c2e.

Vendor ID Security

The vendor ID is hardcoded to PCI:0x1028.

Build Requirements

For Dell support you will need libsmbios_c version 2.4.0 or later.

If you don't want or need this functionality you can use the -Dplugin_dell=false option.

Devices powered by the Dell Plugin

The Dell ESRT plugin allows the user to enable the UpdateCapsule functionality at runtime. A reboot will be required and the BIOS administrator password must not be set.

Machines that offer this functionality will display an extra device in # fwupdmgr get-devices output.

Example:

UEFI dummy device
  Guid:                 2d47f29b-83a2-4f31-a2e8-63474f4d4c2e

  • read/write access to /dev/wmi/dell-smbios and /sys/bus/platform/devices/dcdbas.
  • read access to /sys/firmware/efi/esrt.
