* 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.
* 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.
(UTIL_DISTFILES): Added biosdisk.c and pupa-setup.c under the
directory util/i386/pc.
(install-local): Added a rule for sbin_UTILITIES.
(uninstall): Likewise.
* util/i386/pc/pupa-mkimage.c (usage): Fix a typo in the doc.
* util/misc.c (xrealloc): New function.
(pupa_malloc): Likewise.
(pupa_free): Likewise.
(pupa_realloc): Likewise.
(pupa_stop): Likewise.
(pupa_putchar): Likewise.
* kern/disk.c (pupa_disk_read): Prevent L from underflowing.
* include/pupa/util/misc.h (xrealloc): Declared.
* include/pupa/i386/pc/boot.h (PUPA_BOOT_MACHINE_BPB_START): New
macro.
(PUPA_BOOT_MACHINE_BPBEND): Renamed to ...
(PUPA_BOOT_MACHINE_BPB_END): ... this.
* include/pupa/fs.h [PUPA_UTIL] (pupa_fat_init): Declared.
[PUPA_UTIL] (pupa_fat_fini): Likewise.
* fs/fat.c [PUPA_UTIL] (pupa_fat_init): Defined. Maybe a better
way should be implemented.
[PUPA_UTIL] (pupa_fat_fini): Likewise.
* disk/i386/pc/biosdisk.c (pupa_biosdisk_call_hook): Increase
the size of NAME for safety.
(pupa_biosdisk_iterate): Search hard disks to 0x90 instead of
0x88.
* conf/i386-pc.rmk (sbin_UTILITIES): New variable.
(pupa_setup_SOURCES): Likewise.
* genmk.rb (Utility#rule): Add $(BUILD_CFLAGS) into the rules.
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.
