Represents the state of the PIC.

Fields

last_irr: u8

Edge detection.

irr: u8

Interrupt Request Register.

imr: u8

Interrupt Mask Register.

isr: u8

Interrupt Service Register.

priority_add: u8

Highest priority, for priority rotation.

irq_base: u8

read_reg_select: bool

poll: bool

special_mask: bool

init_state: PicInitState

auto_eoi: bool

rotate_on_auto_eoi: bool

special_fully_nested_mode: bool

use_4_byte_icw: bool

PIC takes either 3 or 4 bytes of initialization command word during initialization. use_4_byte_icw is true if 4 bytes of ICW are needed.

elcr: u8

“Edge/Level Control Registers”, for edge trigger selection. When a particular bit is set, the corresponding IRQ is in level-triggered mode. Otherwise it is in edge-triggered mode.

elcr_mask: u8

Trait Implementations

impl Clone for PicState

fn clone(&self) -> PicState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PicState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PicState

fn default() -> PicState

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PicState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&PicState> for kvm_pic_state

fn from(item: &PicState) -> Self

Converts to this type from the input type.

impl From<&kvm_pic_state> for PicState

fn from(item: &kvm_pic_state) -> Self

Converts to this type from the input type.

impl PartialEq for PicState

fn eq(&self, other: &PicState) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PicState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PicState

impl Eq for PicState

impl StructuralPartialEq for PicState
