31 Note(1): x86_64's has special implementation for memory hotplug.
40 1.1 purpose of memory hotplug
53 Linux memory hotplug is designed for both purpose.
56 1.2. Phases of memory hotplug
85 (However, if you writes udev's hotplug scripts for memory hotplug, these
91 Memory hotplug uses SPARSEMEM memory model which allows memory to be divided
110 To use memory hotplug feature, kernel must be compiled with following
113 - For all memory hotplug
121 - For ACPI memory hotplug, the followings are also necessary
122 Memory hotplug (under ACPI Support menu) (CONFIG_ACPI_HOTPLUG_MEMORY)
125 - As a related configuration, if your box has a feature of NUMA-node hotplug
133 3 sysfs files for memory hotplug
144 the existence of one should not affect the hotplug capabilities of the memory
185 These directories/files appear after physical memory hotplug phase.
203 On x86_64/ia64 platform, memory hotplug by ACPI is supported.
205 In general, the firmware (ACPI) which supports memory hotplug defines
207 Linux's ACPI handler does hot-add memory to the system and calls a hotplug udev
210 But scripts for memory hotplug are not contained in generic udev package(now).
214 If firmware supports NUMA-node hotplug, and defines an object _HID "ACPI0004",
216 calls hotplug code for all of objects which are defined in it.
217 If memory device is found, memory hotplug code will be called.
