From c51d84dc09476d9c06b8aac726220bf3c7d62e8d Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Mon, 23 Sep 2013 17:23:35 -0500 Subject: 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. --- src/shared/boot-timestamps.h | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 src/shared/boot-timestamps.h (limited to 'src/shared/boot-timestamps.h') diff --git a/src/shared/boot-timestamps.h b/src/shared/boot-timestamps.h new file mode 100644 index 0000000000..a3d2405b56 --- /dev/null +++ b/src/shared/boot-timestamps.h @@ -0,0 +1,27 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +#pragma once + +/*** + This file is part of systemd. + + Copyright 2012 Lennart Poettering + Copyright 2013 Kay Sievers + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
