xen-unstable c/s 23874:651aed73b39c added another member to xen_domctl_getdomaininfo struct and bumped domctl version to 8. Add a corresponding domctl v8 struct in xen hypervisor sub-driver and detect domctl v8 during initialization. --- src/xen/xen_hypervisor.c | 129 +++++++++++++++++++++++++++++++++------------ 1 files changed, 94 insertions(+), 35 deletions(-) diff --git a/src/xen/xen_hypervisor.c b/src/xen/xen_hypervisor.c index 941686f..ee3a59c 100644 --- a/src/xen/xen_hypervisor.c +++ b/src/xen/xen_hypervisor.c @@ -243,12 +243,30 @@ struct xen_v2d7_getdomaininfo { }; typedef struct xen_v2d7_getdomaininfo xen_v2d7_getdomaininfo; +struct xen_v2d8_getdomaininfo { + domid_t domain; /* the domain number */ + uint32_t flags; /* flags, see before */ + uint64_t tot_pages ALIGN_64; /* total number of pages used */ + uint64_t max_pages ALIGN_64; /* maximum number of pages allowed */ + uint64_t shr_pages ALIGN_64; /* number of shared pages */ + uint64_t paged_pages ALIGN_64; /* number of paged pages */ + uint64_t shared_info_frame ALIGN_64; /* MFN of shared_info struct */ + uint64_t cpu_time ALIGN_64; /* CPU time used */ + uint32_t nr_online_vcpus; /* Number of VCPUs currently online. */ + uint32_t max_vcpu_id; /* Maximum VCPUID in use by this domain. */ + uint32_t ssidref; + xen_domain_handle_t handle; + uint32_t cpupool; +}; +typedef struct xen_v2d8_getdomaininfo xen_v2d8_getdomaininfo; + union xen_getdomaininfo { struct xen_v0_getdomaininfo v0; struct xen_v2_getdomaininfo v2; struct xen_v2d5_getdomaininfo v2d5; struct xen_v2d6_getdomaininfo v2d6; struct xen_v2d7_getdomaininfo v2d7; + struct xen_v2d8_getdomaininfo v2d8; }; typedef union xen_getdomaininfo xen_getdomaininfo; @@ -258,6 +276,7 @@ union xen_getdomaininfolist { struct xen_v2d5_getdomaininfo *v2d5; struct xen_v2d6_getdomaininfo *v2d6; struct xen_v2d7_getdomaininfo *v2d7; + struct xen_v2d8_getdomaininfo *v2d8; }; typedef union xen_getdomaininfolist xen_getdomaininfolist; @@ -295,179 +314,211 @@ typedef struct xen_v2s5_availheap xen_v2s5_availheap; #define XEN_GETDOMAININFOLIST_ALLOC(domlist, size) \ (hv_versions.hypervisor < 2 ?
