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.
18 Memory hotplug support for Xen balloon driver allows expanding memory
24 memory ranges to use in order to map foreign memory or grants.

54 int "Hotplugged memory limit (in GiB) for a PV guest"
59 Maximum amount of memory (in GiB) that a PV guest can be
60 expanded to when using memory hotplug.

336 bool "Use unpopulated memory ranges for guest mappings"
340 Use unpopulated memory ranges in order to create mappings for guest
341 memory regions, including grant maps and foreign pages. This avoids
342 having to balloon out RAM regions in order to obtain physical memory
