Struct MmHandle 

pub struct MmHandle { /* private fields */ }

Explicit process ownership of an address space.

Implementations

impl MmHandle

pub fn id(&self) -> AddressSpaceId

pub fn state(&self) -> MmState

pub fn user_refs(&self) -> usize

pub fn kernel_pins(&self) -> usize

pub fn active_cpus(&self) -> usize

pub fn active_cpu_mask(&self) -> usize

pub fn cpu_state(&self) -> AddressSpaceCpuState

Returns an observation of the single scheduler-owned CPU footprint.

This value is deliberately read-only: callers cannot publish a second active mask beside the ActivationLease counters in MmInner.

pub fn installed(&self) -> InstalledAddressSpace

pub fn transparent_huge_page_mode(&self) -> TransparentHugePageMode

Returns the process policy attached to this MM identity.

pub fn set_transparent_huge_page_mode(&self, mode: TransparentHugePageMode)

Changes the process-wide THP policy while excluding concurrent faults.

pub fn refresh_installation(&self)

Refreshes the software view after a page-table root replacement.

pub fn clone_user_ref(&self) -> Result<Self, CloneUserRefError>

Explicitly duplicates a process owner (fork, CLONE_VM, or vfork).

pub fn pin(&self) -> Result<MmPin, PinError>

pub fn activation(&self, cpu: usize) -> Result<ActivationLease, ActivationError>

pub fn retire_if_quiescent(&self) -> Option<RetirePermit>

Transitions the last user owner to Retiring without reclaiming data.

pub fn release_user_ref(&self) -> Option<RetirePermit>

Releases this handle’s process ownership while retaining a non-owning view of the address space. This is the operation used by process exit; unlike cloning and dropping a temporary handle, it cannot keep the owner count artificially non-zero.

Trait Implementations

impl Drop for MmHandle

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
