Struct ProcessorVtlHv

pub struct ProcessorVtlHv {
    pub synic: ProcessorSynic,
    /* private fields */
}

A virtual processor’s per-VTL hypervisor state.

Fields

synic: ProcessorSynic

The virtual processor’s synic state.

Implementations

impl ProcessorVtlHv

pub fn ref_time_now(&self) -> u64

The current reference time.

pub fn reset(&mut self)

Resets the processor’s state.

pub fn msr_write_guest_os_id(&mut self, v: u64)

Emulates an MSR write for the guest OS ID MSR.

pub fn msr_write_vp_assist_page(&mut self, v: u64) -> Result<(), MsrError>

Emulates an MSR write for the VP assist page MSR.

pub fn msr_write( &mut self, n: u32, v: u64, overlay_access: &mut dyn VtlProtectHypercallOverlay, ) -> Result<(), MsrError>

Emulates an MSR write for an HV#1 synthetic MSR.

pub fn vsm_code_page_offsets(&self, bit64: bool) -> HvRegisterVsmCodePageOffsets

Gets the VSM code page offset register that corresponds to the hypercall page generated by this emulator.

pub fn msr_read(&self, msr: u32) -> Result<u64, MsrError>

Emulates an MSR read for an HV#1 synthetic MSR.

pub fn vp_assist_page(&self) -> u64

Returns the current value of the VP assist page register.

pub fn set_lazy_eoi(&mut self) -> bool

Sets the lazy EOI bit in the VP assist page.

If this returns true, the caller must call clear_lazy_eoi after the next VP exit but before manipulating the APIC.

pub fn clear_lazy_eoi(&mut self) -> bool

Clears the lazy EOI bit in the VP assist page.

Must only be called if set_lazy_eoi returned true.

If the bit was already clear, returns true; the caller must then send an EOI to the APIC.

pub fn return_registers(&self) -> Result<[u64; 2], GuestMemoryError>

Get the register values to restore on vtl return

pub fn set_return_reason( &self, reason: HvVtlEntryReason, ) -> Result<(), GuestMemoryError>

Set the reason for the vtl return into the vp assist page

pub fn vina_asserted(&self) -> Result<bool, GuestMemoryError>

Gets whether VINA is currently asserted.

pub fn set_vina_asserted(&self, value: bool) -> Result<(), GuestMemoryError>

Sets whether VINA is currently asserted.

Trait Implementations

impl Inspect for ProcessorVtlHv

fn inspect(&self, req: Request<'_>)

Inspects the object.
