History
Richard Hughes e87fc05ab9 Speed up the daemon startup by ~2% by doing dlsym much less 
We were calling g_module_symbol() 2703 times, which is actually more
expensive than you'd think.

It also means the plugins are actually what we tell people they are:
A set of vfuncs that get run. The reality before that they were dlsym'd
functions that get called at pretty random times.

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:
