Struct Version

pub struct Version(/* private fields */);

Value of the VERSION register in the local APIC.

Implementations

impl Version

pub const VERSION: Pack32<u8, Self>

The version numbers of the local APIC:

• 0XH: 82489DX discrete APIC. -10H - 15H: Integrated APIC. Other values reserved.

pub const MAX_LVT: Pack32<u8, Self>

The maximum number of LVT entries in the local APIC, minus one.

For the Pentium 4 and Intel Xeon processors (which have 6 LVT entries), the value returned in the Max LVT field is 5; for the P6 family processors (which have 5 LVT entries), the value returned is 4; for the Pentium processor (which has 4 LVT entries), the value returned is 3. For processors based on the Nehalem microarchitecture (which has 7 LVT entries) and onward, the value returned is 6.

pub const EOI_SUPPRESSION: Pack32<bool, Self>

Indicates whether software can inhibit the broadcast of EOI message by setting bit 12 of the Spurious Interrupt Vector Register; see Section 12.8.5 and Section 12.9. in Ch. 7 of Vol. 3A of the Intel SDM for details.

pub const fn from_bits(bits: u32) -> Self

Constructs a new instance of Self from the provided raw bits.

pub const fn new() -> Self

Constructs a new instance of Self with all bits set to 0.

pub const fn bits(self) -> u32

Returns the raw bit representatiion of self as an integer.

pub fn with<T>(self, field: Pack32<T, Self>, value: T) -> Self

where T: FromBits<u32>,

Packs the bit representation of value into self at the bit range designated by field, returning a new bitfield.

pub fn set<T>(&mut self, field: Pack32<T, Self>, value: T) -> &mut Self

where T: FromBits<u32>,

Packs the bit representation of value into self at the range designated by field, mutating self in place.

pub fn get<T>(self, field: Pack32<T, Self>) -> T

where T: FromBits<u32>,

Unpacks the bit range represented by field from self, and converts it into a T-typed value.

Panics

This method panics if self does not contain a valid bit pattern for a T-typed value, as determined by T’s FromBits::try_from_bits implementation.

pub fn try_get<T>(self, field: Pack32<T, Self>) -> Result<T, T::Error>

where T: FromBits<u32>,

Unpacks the bit range represented by field from self and attempts to convert it into a T-typed value.

Returns

• Ok(T) if a T-typed value could be constructed from the bits in src
• Err(T::Error) if src does not contain a valid bit pattern for a T-typed value, as determined by T’s [FromBits::try_from_bits implementation.

pub fn assert_valid()

Asserts that all the packing specs for this type are valid.

This is intended to be used in unit tests.

pub fn display_ascii(&self) -> impl Display

Returns a value that formats this bitfield in a multi-line format, using only ASCII characters.

This is equivalent to formatting this bitfield using a {} display specifier, but will never use Unicode box-drawing characters, even when an upstream formatter uses the {:#} fmt::Display specifier. This is intended for use on platforms where Unicode box drawing characters are never available.

pub fn display_unicode(&self) -> impl Display

Returns a value that formats this bitfield in a multi-line format, always using Unicode box-drawing characters.

This is equivalent to formatting this bitfield using a {:#} format specifier, but will always use Unicode box-drawing characters, even when an upstream formatter uses the {} fmt::Display specifier.
