Struct x86_64::registers::control::Cr0Flags

pub struct Cr0Flags { /* fields omitted */ }

Configuration flags of the Cr0 register.

Implementations

impl Cr0Flags

pub const PROTECTED_MODE_ENABLE: Cr0Flags

Enables protected mode.

pub const MONITOR_COPROCESSOR: Cr0Flags

Enables monitoring of the coprocessor, typical for x87 instructions.

Controls together with the TASK_SWITCHED flag whether a wait or fwait instruction should cause a device-not-available exception.

pub const EMULATE_COPROCESSOR: Cr0Flags

Force all x87 and MMX instructions to cause an exception.

pub const TASK_SWITCHED: Cr0Flags

Automatically set to 1 on hardware task switch.

This flags allows lazily saving x87/MMX/SSE instructions on hardware context switches.

pub const NUMERIC_ERROR: Cr0Flags

Enables the native error reporting mechanism for x87 FPU errors.

pub const WRITE_PROTECT: Cr0Flags

Controls whether supervisor-level writes to read-only pages are inhibited.

When set, it is not possible to write to read-only pages from ring 0.

pub const ALIGNMENT_MASK: Cr0Flags

Enables automatic alignment checking.

pub const NOT_WRITE_THROUGH: Cr0Flags

Ignored. Used to control write-back/write-through cache strategy on older CPUs.

pub const CACHE_DISABLE: Cr0Flags

Disables internal caches (only for some cases).

pub const PAGING: Cr0Flags

Enables page translation.

pub fn empty() -> Cr0Flags

Returns an empty set of flags

pub fn all() -> Cr0Flags

Returns the set containing all flags.

pub fn bits(&self) -> u64

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u64) -> Option<Cr0Flags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u64) -> Cr0Flags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub unsafe fn from_bits_unchecked(bits: u64) -> Cr0Flags

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: Cr0Flags) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: Cr0Flags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: Cr0Flags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: Cr0Flags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Cr0Flags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Cr0Flags, value: bool)

Inserts or removes the specified flags depending on the passed value.
