[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 2/4] xen: update for interface changes in Xen 4.3 release.
New hypercalls:
- VKI_XENMEM_claim_pages
- VKI_XEN_DOMCTL_getnodeaffinity
- VKI_XEN_DOMCTL_setnodeaffinity
Plus placeholders for other new hypercalls which we don't yet support here.
New revision of sysctl and domctl interfaces, due to new field in
outstanding_pages field in physinfo and dominfo.
Xen changed the API but not ABI of cpumasks to be a more generic bitmask.
Switch to using the latest names.
