I assume we want the same behavior on ia64. This would mean we definitely need to save an untrimmed EFI memory map. -- Khalid On Mon, 2004-11-15 at 15:03, David Mosberger wrote: > >>>>> On Mon, 15 Nov 2004 13:15:25 -0800, "Luck, Tony" said: > > > Tony> You can add your own new requirement to not modify the > Tony> original EFI tables so that they can be re-scanned by a new > Tony> kernel after kexec (new kernel might have a different granule > Tony> size). > > That certainly would be the right way to go about it.
