I have a powerpc board with 512BM of memory. The BIOS has a chunk of memory at the top end of physical memory which it does not zero out over a reboot.
What's the proper way to tell linux that this chunk of physical memory should be ignored (so that we can access it later without worrying that Linux will try to allocate it)? Should I be calling lmb_reserve(lmb_end_of_DRAM() - size, size); in early_reserve_mem() or is there a better mechanism? For comparison, in an older kernel this was done in set_phys_avail(), by calling mem_pieces_remove(&phys_avail, total_lowmem - size, size, 1); Thanks, Chris _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
