support acpi firmware performance data (FPDT) Prefer firmware-provided performance data over loader-exported ones; if ACPI data is available, always use it, otherwise try to read the loader data. The firmware-provided variables start at the time the first EFI image is executed and end when the operating system exits the boot services; the (loader) time calculated in systemd-analyze increases. 2013-09-24 00:23:35 +02:00			`#pragma once`
