2003-09-25 Yoshinori K. Okuji * genmk.rb (PModule#rule): Make sure to get only symbol names from the output of nm. Reported by Robert Millan . 2003-09-25 Yoshinori K. Okuji I forgot to check in these changes for a long time. This adds incomplete support for VGA console, and this is still very buggy.

(pupa_dl_unload): Unload depending modules explicitly, if possible. 2003-01-17 Yoshinori K. Okuji * 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_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.

Okuji * 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. 2003-01-03 Yoshinori K. Okuji * include/i386/pc/util/biosdisk.h: New file. * util/i386/pc/biosdisk.c: Likewise. * util/i386/pc/pupa-setup.c: Likewise. * Makefile.in (INCLUDE_DISTFILES): Added include/pupa/i386/pc/util/biosdisk.h.

Okuji * kern/i386/pc/startup.S (push_get_mmap_entry): Revert to a bunch of pushl's from pusha, because this destroys the return value. 2002-12-28 Yoshinori K. Okuji 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_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. 2002-12-27 Yoshinori K. Okuji * 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 Yoshinori K. Okuji * Makefile.in (BUILD_CC): CC -> BUILD_CC. 2002-12-27 Yoshinori K. Okuji * Changelog: New file.
