New in 0.7:
* Problems in cross-compiling PUPA are fixed.
* 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.
* New utility, ``pupa-setup''. This sets up PUPA to make it bootable
from a real disk.

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_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_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
