I am developping a kernel that is split in modules for my studies, using GRUB to boot it and load modules in memory. GRUB allocates space for the sections in the kernel ELF, and also reserves space for the bss symbols. Is it possible to tell GRUB to reserve space for the bss symbols, for a module ?

I did not find any information relating to that point, and as of now, all the modules i load are concateneted in memory (page aligned), leaving no space for the bss symbols. Do i really have to parse the elf headers and allocate the space myself ?
