# 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.
|
|
|
|
