6 * These structs MUST NOT be changed.
7 * They are the ABI between hypervisor and guest OS.
8 * Both Xen and KVM are using this.
9 *
10 * pvclock_vcpu_time_info holds the system time and the tsc timestamp
11 * of the last update. So the guest can use the tsc delta to get a
12 * more precise system time. There is one per virtual cpu.
13 *
14 * pvclock_wall_clock references the point in time when the system
15 * time was zero (usually boot time), thus the guest calculates the
16 * current wall clock by adding the system time.
17 *
18 * Protocol for the "version" fields is: hypervisor raises it (making
19 * it uneven) before it starts updating the fields and raises it again
20 * (making it even) when it is done. Thus the guest can make sure the
21 * time values it got are consistent by checking the version before
22 * and after reading them.
