From 1eca02d86384bd399f3d3b0fce5e6be48ce8156f Mon Sep 17 00:00:00 2001 From: Dave Chapman Date: Tue, 4 Aug 2009 20:32:30 +0000 Subject: Add support (on Linux and win32 only - I couldn't figure this out on OS X) for reading the XML device information from ipods. This information includes the RAM size, which is potentially useful for rbutil to distinguish between the two ipod video builds. This is implemented as both a new --dump-xml option (to dump the entire XML to a file) and a new 'ramsize' field in struct ipod_t. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22165 a1c6a512-1295-4272-9138-f99709370657 --- rbutil/ipodpatcher/ipodio-win32-scsi.c | 118 +++++++++++++++++++++++++++++++++ 1 file changed, 118 insertions(+) create mode 100644 rbutil/ipodpatcher/ipodio-win32-scsi.c (limited to 'rbutil/ipodpatcher/ipodio-win32-scsi.c') diff --git a/rbutil/ipodpatcher/ipodio-win32-scsi.c b/rbutil/ipodpatcher/ipodio-win32-scsi.c new file mode 100644 index 0000000000..5843ce5d2f --- /dev/null +++ b/rbutil/ipodpatcher/ipodio-win32-scsi.c @@ -0,0 +1,118 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id: ipodio-win32.c 17847 2008-06-28 18:10:04Z bagder $ + * + * Copyright (C) 2009 Dave Chapman + * + * 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. + * + * + * Based on the getCapsUsingSCSIPassThrough() function from "cddrv.cpp": + * - http://www.farmanager.com/svn/trunk/unicode_far/cddrv.cpp + * + * Copyright (c) 1996 Eugene Roshal + * Copyright (c) 2000 Far Group + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
