2004-04-04 Yoshinori K. Okuji <okuji@enbug.org> All symbols prefixed with PUPA_ and pupa_ are renamed to GRUB_ and grub_, respectively. Because the conversion is trivial and mechanical, I omit the details here. Please refer to the CVS if you need more information.

New in 1.90:
* Rename the project name PUPA to GRUB. Now this version is the
developmental version of GRUB officially.
* The GRUB emulator ``grub-emu'' is added.
* Add support for newworld Mac. This should work with other
PowerPC-based machines as well, if they use IEEE 1275
(Open Firmware).
2002-12-27 Yoshinori K. Okuji <okuji@enbug.org> * configure.ac: Check ld. Replace CFLAGS and CPPFLAGS with BUILD_CFLAGS and BUILD_CPPFLAGS respectively, before checking endianness and sizes. * Makefile.in (LD): New variable.
2002-12-27 14:14:06 +00:00
New in 0.7:
* Problems in cross-compiling PUPA are fixed.
2002-12-28 Yoshinori K. Okuji <okuji@enbug.org> Use -mrtd and -mregparm=3 to reduce the generated code sizes. This means that any missing prototypes could be fatal. Also, you must take care when writing assembly code. See the comments at the beginning of startup.S, for more details. * kern/i386/pc/startup.S (pupa_halt): Modified for the new compilation mechanism. (pupa_chainloader_real_boot): Likewise. (pupa_biosdisk_rw_int13_extensions): Likewise. (pupa_biosdisk_rw_standard): Likewise. (pupa_biosdisk_check_int13_extensions): Likewise. (pupa_biosdisk_get_diskinfo_int13_extensions): Likewise. (pupa_biosdisk_get_diskinfo_standard): Likewise. (pupa_get_memsize): Likewise. (pupa_get_mmap_entry): Likewise. (pupa_console_putchar): Likewise. (pupa_console_setcursor): Likewise. (pupa_getrtsecs): Use pushl instead of push. * kern/i386/pc/init.c (pupa_machine_init): Use the scratch memory instead of the stack for a mmap entry, because some BIOSes may ignore the maximum size and overflow. * conf/i386-pc.rmk (COMMON_CFLAGS): Added -mrtd and -mregparm=3. * genmk.rb (PModule#rule): Compile automatically generated sources with module-specific CFLAGS as well as other sources.

* Use -mrtd and -mregparm=3 to reduce the generated code sizes. This
means that any missing prototypes could be fatal. Also, you must take
care when writing assembly code. See the comments at the beginning of
startup.S, for more details.
2003-01-03 Yoshinori K. Okuji <okuji@enbug.org> * util/i386/pc/pupa-setup.c (setup): Define the internal function find_first_partition_start at the top level, because GCC 3.0.x cannot compile internal functions in deeper scopes correctly. (find_root_device): Use lstat instead of stat. Don't follow symbolic links. Fix the path-constructing code. * util/i386/pc/biosdisk.c [__linux__] (BLKFLSBUF): New macro. (pupa_util_biosdisk_open) [__linux__]: Get the size of a device by a BLKGETSIZE ioctl first, because block devices don't fill the member st_mode of the structure stat on Linux. [__linux__] (linux_find_partition): Use a temporary buffer REAL_DEV for the working space. Copy it to DEV before returning. (open_device) [__linux__]: Call ioctl with BLKFLSBUF to make the buffer cache consistent. (get_os_disk) [__linux__]: Use the length 5 instead of 4 for strncmp. The previous value was merely wrong. (pupa_util_biosdisk_get_pupa_dev): Use stat instead of lstat. * fs/fat.c (pupa_fat_read_data): Shift 4 instead of 12 when the FAT size is 12. The previous value was merely wrong. * kern/main.c (pupa_main): Don't split the starting message from newlines. * kern/term.c (pupa_putchar): Put CR after LF instead of before LF, because BIOS goes crazy about character attributes in this case.
2003-01-02 23:46:21 +00:00
* New utility, ``pupa-setup''. This sets up PUPA to make it bootable
from a real disk.

(pupa_dl_get_prefix): New function. * include/pupa/i386/pc/kernel.h: Include pupa/types.h. (PUPA_KERNEL_MACHINE_INSTALL_DOS_PART): New macro. (PUPA_KERNEL_MACHINE_INSTALL_BSD_PART): Likewise. (PUPA_KERNEL_MACHINE_PREFIX): Likewise. (pupa_install_dos_part): Declared. (pupa_install_bsd_part): Likewise. (pupa_prefix): Likewise. (pupa_boot_drive): Likewise. * include/pupa/types.h: Fix a typo. * include/pupa/misc.h (pupa_memcpy): New macro. Just an alias to pupa_memmove. (pupa_memmove): Declared. (pupa_strcpy): Likewise. * include/pupa/dl.h (PUPA_MOD_INIT): Change the prototype. Now pupa_mod_init takes one argument, its own module. (pupa_dl_unload_unneeded): Declared. (pupa_dl_unload_all): Likewise. (pupa_dl_ref): Likewise. (pupa_dl_unref): Likewise. (pupa_dl_iterate): Likewise. (pupa_dl_init): Renamed to ... (pupa_dl_set_prefix): ... this.

2003-01-06 00:01:35 +00:00
* New commands, "prefix", "insmod", "rmmod" and "lsmod" are added into
the rescue mode to manipulate PUPA modules.
2003-01-17 Yoshinori K. Okuji <okuji@enbug.org> * include/pupa/i386/pc/linux.h: New file. * loader/i386/pc/linux.c: Likewise. * loader/i386/pc/chainloader.c (pupa_chainloader_boot_sector): Removed. (pupa_chainloader_unload): Return PUPA_ERR_NONE. (pupa_rescue_cmd_chainloader): Read the image to 0x7C00 instead of PUPA_CHAINLOADER_BOOT_SECTOR. * kern/i386/pc/startup.S: Include pupa/machine/linux.h. (pupa_linux_prot_size): New variable.

(pupa_machine_init): Set PUPA_LOWER_MEM and PUPA_UPPER_MEM to the size of the conventional memory and that of so-called upper memory (before the first memory hole). Instead of adding each found region to free memory, use add_mem_region and add them after removing overlaps. Also, add only 1/4 of the upper memory to free memory. The rest is used for loading OS images. Maybe this is ad hoc, but this makes it much easier to relocate OS images when booting. * kern/rescue.c (pupa_rescue_cmd_module): Removed. (pupa_enter_rescue_mode): Don't register initrd and module. * kern/mm.c: Include pupa/dl.h. * kern/main.c: Include pupa/file.h and pupa/device.h. * kern/loader.c (pupa_loader_load_module_func): Removed. (pupa_loader_load_module): Likewise. * kern/dl.c (pupa_dl_load): Use the suffix ``.mod'' instead of ``.o''. * include/pupa/i386/pc/loader.h (pupa_linux_prot_size): Declared. (pupa_linux_tmp_addr): Likewise. (pupa_linux_real_addr): Likewise. (pupa_linux_boot_zimage): Likewise. (pupa_linux_boot_bzimage): Likewise. * include/pupa/i386/pc/init.h (pupa_lower_mem): Declared. (pupa_upper_mem): Likewise. (pupa_gate_a20): Don't export, because turning off Gate A20 in a module is too dangerous. * include/pupa/loader.h (pupa_os_area_addr): Declared. (pupa_os_area_size): Likewise. (pupa_loader_set): Remove the first argument. Loader doesn't manage modules or initrd any longer. (pupa_loader_load_module): Removed. * conf/i386-pc.rmk (pkgdata_MODULES): Added linux.mod. (linux_mod_SOURCES): New variable. (linux_mod_CFLAGS): Likewise.
2003-01-17 02:52:05 +00:00

(pupa_util_load_image): New function. * kern/i386/pc/startup.S: Include pupa/machine/kernel.h. (pupa_compressed_size): New variable. (codestart): Enable Gate A20 here. Decompress the compressed part of the core image. Rearrange the code to put functions and variables which are required for initialization in the non-compressed part. Include lzo1x.S. * kern/i386/pc/init.c (pupa_machine_init): Don't enable Gate A20 here. * include/pupa/util/misc.h (pupa_util_write_image): Declared. * include/pupa/i386/pc/kernel.h (PUPA_KERNEL_MACHINE_COMPRESSED_SIZE): New macro. (PUPA_KERNEL_MACHINE_INSTALL_DOS_PART): Increased by 4. (PUPA_KERNEL_MACHINE_INSTALL_BSD_PART): Likewise. (PUPA_KERNEL_MACHINE_PREFIX): Likewise. (PUPA_KERNEL_MACHINE_RAW_SIZE): New macro. * conf/i386-pc.rmk (pupa_mkimage_LDFLAGS): New variable. * genmk.rb (Image#rule): Put LDFLAGS at the end of a line. (Utility#rule): Likewise. * configure.ac: Check if LZO is available.
2003-01-31 03:26:56 +00:00
* Reduce the size of a core image significantly by compressing a large
part of the core image and decompressing itself at boot time. The
currently used algorithm is LZO (more precisely, LZO1X-999). So you
have to install LZO to build PUPA. See
<http://www.oberhumer.com/opensource/lzo/>, for more information.
