Hi, Now, SYSTEM_RAM is registerd to resouce list and a user can see memory map from /proc/iomem, like following. == [kamezawa@drpq linux-2.6.23-rc8-mm2]$ grep RAM /proc/iomem 00000000-0009ffff : System RAM 00100000-03ffffff : System RAM 04000000-04f1bfff : System RAM 04f1c000-6b4b9fff : System RAM 6b4ba000-6b797fff : System RAM 6b798000-6b799fff : System RAM 6b79a000-6b79dfff : System RAM 6b79e000-6b79efff : System RAM 6b79f000-6b7fbfff : System RAM 6b7fc000-6c629fff : System RAM 6c62a000-6c800fff : System RAM 6c801000-6c843fff : System RAM 6c844000-6c847fff : System RAM 6c848000-6c849fff : System RAM 6c84a000-6c85dfff : System RAM 6c85e000-6c85efff : System RAM 6c85f000-6cbfbfff : System RAM 6cbfc000-6d349fff : System RAM 6d34a000-6d3fbfff : System RAM 6d3fc000-6d455fff : System RAM 6d4fc000-6d773fff : System RAM 100000000-7ffffffff : System RAM 4080000000-40ffffffff : System RAM 14004000000-147ffffffff : System RAM == But there is a confusion. i386 and x86_64 registers System RAM as IORESOUCE_MEM | IORESOUCE_BUSY. ia64 registers System RAM as IORESOURCE_MEM. Which is better ? I ask this because current memory hotplug treat memory as IORESOUCE_MEM. When memory hot-add occurs on x86_64, new memory is added as IORESOUCE_MEM. memory hot-remove (now) can remove only IORESOUCE_MEM. If ia64 should treat System RAM as IORESOUCE_MEM | IORESOUCE_BUSY, I'll write a fix.
