Implementations§

impl PvclockSharedData

pub fn new(mem: GuestMemory, addr: GuestAddress) -> Self

fn snapshot(&self) -> GuestAddress

Only the seqlock_addr is needed to re-create this struct at restore time, so that is all our snapshot contains.

pub fn zero_fill(&mut self) -> Result<()>

Set all fields to zero.

pub fn increment_seqlock(&mut self) -> Result<()>

pub fn set_tsc_suspended_delta(&mut self, delta: u64) -> Result<()>

pub fn set_tsc_frequency(&mut self, frequency: u64) -> Result<()>

pub fn enable_pvclock_flags(&mut self, flags: u8) -> Result<()>
