They are obviously picked by Xen and provided to dom0 > somehow, but how and where? I'm not sure I understand your question fully. It comes from memory descriptor which xen creates. I.e. it is calculated based on ia64_boot_param->efi_memmap. dom_fw_init() creates it in xen. Presumably you have heavily modified those code and real memory map which boot loader(elilo?) creates is passed thourgh to dom0. -- yamahata _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-ia64-devel |
