Add support for HAP feature to xen drivers
|
|
|
|
xen-unstable c/s 16931 introduced a per-domain setting for hvm
|
|
guests to enable/disable hardware assisted paging. If disabled,
|
|
software techniques such as shadow page tables are used. If enabled,
|
|
and the feature exists in underlying hardware, hardware support for
|
|
paging is used.
|
|
|
|
This provides implementation for mapping HAP setting to/from
|
|
domxml/native formats in xen drivers.
