Here is my first work about porting grub2 to ultrasparc : sun's partition map support. The code was inspired by libparted (structs and the checksum function that I slightly modified). This patch also enables i386-pc to test it, maybe it should also be done for apple. Tested to work with parted-generated disk images, not tested with a real disk. 2005-01-02 Vincent Pelletier * partmap/sun.c: Added * conf/i386-pc.rmk, include/grub/partition.h, util/grub-emu.c: References to partmap/sun.c added Vincent Pelletier --------------050503000105000207020602 Content-Type: text/plain; name="partmap_sun.diff" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="partmap_sun.diff" Index: conf/i386-pc.rmk =================================================================== RCS file: /cvsroot/grub/grub2/conf/i386-pc.rmk,v retrieving revision 1.23 diff -u -p -r1.23 i386-pc.rmk --- conf/i386-pc.rmk 4 Dec 2004 18:45:45 -0000 1.23 +++ conf/i386-pc.rmk 2 Jan 2005 17:41:34 -0000 @@ -62,6 +62,7 @@ grub_setup_SOURCES = util/i386/pc/grub-s util/misc.c util/i386/pc/getroot.c kern/device.c kern/disk.c \ kern/err.c kern/misc.c fs/fat.c fs/ext2.c \ kern/partition.c partmap/amiga.c partmap/apple.c partmap/pc.c \ + partmap/sun.c \ fs/ufs.c fs/minix.c fs/hfs.c fs/jfs.c kern/file.c kern/fs.c kern/env.c fs/fshelp.c # For grub @@ -70,6 +71,7 @@ grub_emu_SOURCES = kern/main.c kern/devi kern/misc.c kern/loader.c kern/rescue.c kern/term.c \ kern/partition.c kern/env.c commands/ls.c partmap/amiga.c \ partmap/pc.c partmap/apple.c \ + partmap/sun.c \ commands/terminal.c commands/boot.c commands/cmp.c commands/cat.c \ util/i386/pc/biosdisk.c fs/fat.c fs/ext2.c fs/ufs.c fs/minix.c fs/hfs.c fs/jfs.c fs/iso9660.c \ normal/cmdline.c normal/command.c normal/main.c normal/menu.c normal/arg.c \ @@ -83,7 +85,7 @@ genmoddep_SOURCES = util/genmoddep.c pkgdata_MODULES = _chain.mod _linux.mod linux.mod fat.mod ufs.mod ext2.mod minix.mod \ hfs.mod jfs.mod normal.mod hello.mod vga.mod font.mod _multiboot.mod ls.mod \ boot.mod cmp.mod cat.mod terminal.mod fshelp.mod chain.mod multiboot.mod \ - amiga.mod apple.mod pc.mod + amiga.mod apple.mod pc.mod sun.mod # For _chain.mod. _chain_mod_SOURCES = loader/i386/pc/chainloader.c @@ -190,3 +192,12 @@ apple_mod_CFLAGS = $(COMMON_CFLAGS) # For pc.mod pc_mod_SOURCES = partmap/pc.c pc_mod_CFLAGS = $(COMMON_CFLAGS) + +# For sun.mod +sun_mod_SOURCES = partmap/sun.c +sun_mod_CFLAGS = $(COMMON_CFLAGS) + Index: include/grub/partition.h =================================================================== RCS file: /cvsroot/grub/grub2/include/grub/partition.h,v retrieving revision 1.1 diff -u -p -r1.1 partition.h --- include/grub/partition.h 4 Dec 2004 18:45:45 -0000 1.1 +++ include/grub/partition.h 2 Jan 2005 17:41:35 -0000 @@ -89,6 +89,8 @@ void grub_amiga_partition_map_init (void void grub_amiga_partition_map_fini (void); void grub_apple_partition_map_init (void); void grub_apple_partition_map_fini (void); +void grub_sun_partition_map_init (void); +void grub_sun_partition_map_fini (void); #endif static inline unsigned long Index: partmap/sun.c =================================================================== RCS file: partmap/sun.c diff -N partmap/sun.c --- /dev/null 1 Jan 1970 00:00:00 -0000 +++ partmap/sun.c 2 Jan 2005 17:41:37 -0000 @@ -0,0 +1,204 @@ +/* sun.c - Read SUN style partition tables. */ +/* + * GRUB -- GRand Unified Bootloader + * Copyright (C) 2002, 2004 Free Software Foundation, Inc. + * + * GRUB 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 program 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.
