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.

Platform Health Assessment Table

Introduction

The PHAT is an ACPI table where a platform can expose health related telemetry that may be useful for software running within the constraints of an OS.

These elements are typically going to encompass things that are likely otherwise not enumerable during the OS runtime phase of operations, such as version of pre-OS components.

The daemon includes some of the PHAT data in the report data sent to the LVFS so that we can debug failures with the help of the IHV. This allows us to find the root cause of the problem, and so we know what other OEMs may be affected.

See https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html#platform-health-assessment-table for more information.
