I don't understand how you came up with the conclusion that 128MB will be removed from Dom0. We only have the requirement that the first bank is at least 128MB. So can you expand it?
IIRC Linux kernel requires that the machine RAM start must be 128MB aligned. Look at `allocate_memory_11()`, `min_low_order` variable usage. It affects all low memory 1:1 allocation and makes all low memory banks 128MB aligned both start and end. So that having a module in a low memory poisons the whole 128MB region. -- Sincerely, Andrii Anisov. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
