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.

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.
2003-01-06 Yoshinori K. Okuji <okuji@enbug.org> * util/i386/pc/pupa-setup.c: Include pupa/machine/kernel.h. (setup): Configure the installed partition information and the dl prefix. * loader/i386/pc/chainloader.c (my_mod): New variable. (pupa_chainloader_unload): New function. (pupa_rescue_cmd_chainloader): Refer itself. (PUPA_MOD_INIT): Save its own module in MY_MOD. * kern/i386/pc/startup.S (install_partition): Removed. (version_string): Likewise. (config_file): Likewise. (pupa_install_dos_part): New variable. (pupa_install_bsd_part): Likewise. (pupa_prefix): Likewise. (pupa_chainloader_real_boot): Call pupa_dl_unload_all. * kern/i386/pc/init.c: Include pupa/machine/kernel.h, pupa/dl.h and pupa/misc.h. (make_install_device): New function. (pupa_machine_init): Set the dl prefix. * kern/rescue.c: Include pupa/rescue.h and pupa/dl.h. (buf): Renamed to ... (linebuf): ... this. (pupa_rescue_cmd_prefix): New function. (pupa_rescue_cmd_insmod): Likewise. (pupa_rescue_cmd_rmmod): Likewise. (pupa_rescue_cmd_lsmod): Likewise. (pupa_enter_rescue_mode): Register new commands: prefix, insmod, rmmod and lsmod. * kern/mm.c (pupa_memalign): If failed even after invalidating disk caches, unload unneeded modules and retry. * kern/misc.c (pupa_memmove): New function. (pupa_memcpy): Removed. (pupa_strcpy): New function. (pupa_itoa): Made static. * kern/dl.c (pupa_dl_iterate): New function. (pupa_dl_ref): Likewise. (pupa_dl_unref): Likewise. (pupa_dl_unload): Return if succeeded or not. (pupa_dl_unload_unneeded): New function. (pupa_dl_unload_all): Likewise. (pupa_dl_init): Renamed to ... (pupa_dl_set_prefix): ... this. (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. (pupa_dl_get_prefix): Declared. * fs/fat.c [!PUPA_UTIL] (my_mod): New variable. (pupa_fat_dir) [!PUPA_UTIL]: Prevent the fat module from being unloaded. (pupa_fat_open) [!PUPA_UTIL]: Refer itself if succeeded. (pupa_fat_close) [!PUPA_UTIL]: Unrefer itself. * configure.ac (tmp_CFLAGS): Added -Wshadow, -Wpointer-arith, -Wmissing-prototypes, -Wundef and -Wstrict-prototypes.
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.
Initial revision

New in 0.6 - 2002-12-27, Yoshinori K. Okuji:
* The chainloader and the FAT filesystem are modularized.
* The structure of the source tree is a bit changed.
* Support for building loadable modules is added.
* Some generic parts of pupa-mkimage are segregated.
* Some documentation files are added, according to the GNU Coding
Standards.
