From 52e528e057d7fd8d55116edf40500e0c0b3b75e8 Mon Sep 17 00:00:00 2001 From: Torne Wuff Date: Thu, 1 Apr 2010 16:27:21 +0000 Subject: Boot charting support. Select (B)ootchart in advanced options in configure, and logf will record timings for various stages of boot, for performance comparisons. Format logged is: BC:>function_name,123,80 where 123 is the line number, 80 is the number of ticks since boot. This can be loaded as CSV into a spreadsheet. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25426 a1c6a512-1295-4272-9138-f99709370657 --- firmware/export/bootchart.h | 42 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) create mode 100644 firmware/export/bootchart.h (limited to 'firmware/export') diff --git a/firmware/export/bootchart.h b/firmware/export/bootchart.h new file mode 100644 index 0000000000..cad41ee50c --- /dev/null +++ b/firmware/export/bootchart.h @@ -0,0 +1,42 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Copyright (C) 2010 by Torne Wuff + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License + * as published by the Free Software Foundation; either version 2 + * of the License, or (at your option) any later version. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ****************************************************************************/ +#ifndef BOOTCHART_H +#define BOOTCHART_H +#include +#include +#include "../include/_ansi.h" +#include "logf.h" +#include "kernel.h" + +#ifdef DO_BOOTCHART + +/* we call _logf directly to avoid needing LOGF_ENABLE per-file */ +#define CHART2(x,y) _logf("BC:%s%s,%d,%ld", (x), (y), __LINE__, current_tick) +#define CHART(x) CHART2(x,"") + +#else /* !DO_BOOTCHART */ + +#define CHART2(x,y) +#define CHART(x) + +#endif /* DO_BOOTCHART */ + +#endif /* BOOTCHART_H */ -- cgit v1.2.3
