Struct devices::virtio::pvclock::PvClockState

struct PvClockState {
    tsc_frequency: u64,
    paused_main_worker: Option<PvClockWorkerSnapshot>,
    total_suspend_ns: Arc<AtomicU64>,
    features: u64,
    acked_features: u64,
}

Serializable part of the PvClock struct which will be used by the virtio_snapshot / restore.

Fields

tsc_frequency: u64

paused_main_worker: Option<PvClockWorkerSnapshot>

If the device is sleeping, a PvClockWorkerSnapshot that can re-create the worker will be stored here. (We can’t just store the worker itself as it contains an object tree with references to GuestMemory.)

total_suspend_ns: Arc<AtomicU64>

The total time the vm has been suspended, this is in an Arc<AtomicU64>> because it’s set by the PvClockWorker thread but read by PvClock from the mmio bus in the main thread.

features: u64

acked_features: u64
