Plugin: ACPI PHAT — Platform Health Assessment Table


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.
