Hello,
I'm slowly researching amd64 BSP multiboot domain and I'm curious if it is possible based on waf BSP's options to change either (or both) linker/gcc linking options (E.g. to add -z max-page-size=1000) and or process generated exe by other tool like objcopy (to create elf32 from elf64). My findings so far: - GRUB is able to load 64bit ELF for both multiboot and multiboot2 standards. - GRUB is able to load 32bit ELF generated from 64bit for multiboot - Qemu supports multiboot only (not multiboot2!) - Qemu is picky and supports only 32bit ELF for multiboot load Caveat: by "load" I mean (in case of GRUB) that multiboot or multiboot2 command invoked with <elf file> parameter executes without complain from GRUB itself. Also that grub-file --is-x86-multiboot(2) <file> exits with 0 result which signals GRUB claims that's multiboot(2) file. Note: all my experiments so far are "how the heck to put multiboot(2) header into RTEMS AMD64 BSP exe and make GRUB or Qemu or even both happy" category. So it's just the first step for now. Putting multiboot header into elf and in recognizable way... For this, knowing some examples how to modify waf/wscript of the bsp would be great to have... Thanks!
