6 	bool "Xen memory balloon driver"
9 	  The balloon driver allows the Xen domain to request more memory from
10 	  the system to expand the domain's memory allocation, or alternatively
11 	  return unneeded memory to the system.
14 	bool "Memory hotplug support for Xen balloon driver"
18 	  Memory hotplug support for Xen balloon driver allows expanding memory
24 	  memory ranges to use in order to map foreign memory or grants.
26 	  Memory could be hotplugged in following steps:
28 	    1) target domain: ensure that memory auto online policy is in
29 	       effect by checking /sys/devices/system/memory/auto_online_blocks
33 	       where <maxmem> is >= requested memory size,
35 	    3) control domain: xl mem-set <target-domain> <memory>
36 	       where <memory> is requested memory size; alternatively memory
42 	  Alternatively, if memory auto onlining was not requested at step 1
43 	  the newly added memory can be manually onlined in the target domain

54 	int "Hotplugged memory limit (in GiB) for a PV guest"
59 	  Maxmium amount of memory (in GiB) that a PV guest can be

255 	  This is Xen ACPI memory hotplug.
257 	  Currently Xen only support ACPI memory hot-add. If you want

329 	bool "Use unpopulated memory ranges for guest mappings"
333 	  Use unpopulated memory ranges in order to create mappings for guest
334 	  memory regions, including grant maps and foreign pages. This avoids
335 	  having to balloon out RAM regions in order to obtain physical memory
