Linux: Documenting Memory Hotplug

07/29/2007  
Relevance: 7.36
Yasunori Goto posted some documentation for memory hotplugging which can be used to increase or decrease the amount of memory available to a live kernel. The documentation explains that this functionality is useful for virtualization and capacity on demand solutions, as well as for physically adding and removing RAM from NUMA-nodes. The document itself,"is about memory hotplug including how-to-use and current status. Because Memory Hotplug is still under development, contents of this text will be changed often."
