From 2e3d069236777cd62f755a02f4a239306b4ad21a Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Sat, 19 Jan 2013 04:20:23 +0100 Subject: core: if the bootloader supports it, determine firmware and boot loader delay This allows us to print simple performance data of all parts of the boot now: - firmware - boot loader - kernel - initrd - userspace This only works for bootloaders which support passing TSC data via EFI variables. As of now that's only gummiboot. --- src/shared/efivars.h | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 src/shared/efivars.h (limited to 'src/shared/efivars.h') diff --git a/src/shared/efivars.h b/src/shared/efivars.h new file mode 100644 index 0000000000..7b65c9264e --- /dev/null +++ b/src/shared/efivars.h @@ -0,0 +1,30 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +#pragma once + +/*** + This file is part of systemd. + + Copyright 2013 Lennart Poettering + + 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.
