1 | config XEN_BALLOON |
2 | bool "Xen memory balloon driver" | |
3 | depends on XEN | |
4 | default y | |
5 | help | |
6 | The balloon driver allows the Xen domain to request more memory from | |
7 | the system to expand the domain's memory allocation, or alternatively | |
8 | return unneeded memory to the system. | |

12 | depends on XEN_BALLOON | |

14 | help | |
15 | Scrub pages before returning them to the system for reuse by | |
16 | other domains. This makes sure that any confidential data | |
17 | is not accidentally visible to other domains. Is it more | |
18 | secure, but slightly less efficient. | |
19 | If in doubt, say yes. | |

21 | config XENFS | |
22 | tristate "Xen filesystem" | |
23 | depends on XEN | |
24 | default y | |
25 | help | |
26 | The xen filesystem provides a way for domains to share | |
27 | information with each other and with the hypervisor. | |
28 | For example, by reading and writing the "xenbus" file, guests | |
29 | may pass arbitrary information to the initial domain. | |
30 | If in doubt, say yes. | |

32 | config XEN_COMPAT_XENFS | |
33 | bool "Create compatibility mount point /proc/xen" | |
34 | depends on XENFS | |
35 | default y | |
36 | help | |
37 | The old xenstore userspace tools expect to find "xenbus" | |
38 | under /proc/xen, but "xenbus" is now found at the root of the | |
39 | xenfs filesystem. Selecting this causes the kernel to create | |
40 | the compatibilty mount point /proc/xen if it is running on | |
41 | a xen platform. | |
42 | If in doubt, say yes. | |
