* 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_linux_tmp_addr): Likewise. (pupa_linux_real_addr): Likewise. (pupa_linux_boot_zimage): New function. (pupa_linux_boot_bzimage): Likewise. * kern/i386/pc/init.c (struct mem_region): New structure. (MAX_REGIONS): New macro. (mem_regions): New variable. (num_regions): Likewise. (pupa_os_area_addr): Likewise. (pupa_os_area_size): Likewise. (pupa_lower_mem): Likewise. (pupa_upper_mem): Likewise. (add_mem_region): New function. (compact_mem_regions): Likewise. (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. |

This is PUPA, the Preliminary Universal Programming Architecture for
GRUB. PUPA is a research project for the next generation of GNU GRUB.
The most important goal is to make GNU GRUB cleaner, safer, more robust,
more powerful, and more portable.
See the file NEWS for a description of recent changes to PUPA.
See the file INSTALL for instructions on how to build and install the
PUPA data and program files.
Please visit the official web page of PUPA, for more information.
The URL is <http://www.nongnu.org/pupa/>.
Because PUPA is still in developmental stage, PUPA is not for general
use (yet). For now, you can install PUPA into a floppy by these
instructions:
$ configure && make
$ ./pupa-mkimage -v -d . -o core.img chain fat
$ dd if=boot.img of=/dev/fd0 bs=512 count=1
$ dd if=core.img of=/dev/fd0 bs=512 seek=1
It would be easier to use Bochs <http://bochs.sf.net/> than a real
machine.
