The PitChannelState represents the state of one of the PIT’s three counters.

Fields

count: u32

The starting value for the counter.

latched_count: u16

Stores the channel count from the last time the count was latched.

count_latched: PitRWState

Indicates the PitRWState state of reading the latch value.

status_latched: bool

Indicates whether ReadBack status has been latched.

status: u8

Stores the channel status from the last time the status was latched. The status contains information about the access mode of this channel, but changing those bits in the status will not change the behavior of the pit.

read_state: PitRWState

Indicates the PitRWState state of reading the counter.

write_state: PitRWState

Indicates the PitRWState state of writing the counter.

reload_value: u16

Stores the value with which the counter was initialized. Counters are 16- bit values with an effective range of 1-65536 (65536 represented by 0).

rw_mode: PitRWMode

The command access mode of this channel.

mode: u8

The operation mode of this channel.

bcd: bool

Whether or not we are in bcd mode. Not supported by KVM or crosvm’s PIT implementation.

gate: bool

Value of the gate input pin. This only applies to channel 2.

count_load_time: u64

Nanosecond timestamp of when the count value was loaded.

Trait Implementations

impl Clone for PitChannelState

fn clone(&self) -> PitChannelState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PitChannelState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PitChannelState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&PitChannelState> for kvm_pit_channel_state

fn from(item: &PitChannelState) -> Self

Converts to this type from the input type.

impl From<&kvm_pit_channel_state> for PitChannelState

fn from(item: &kvm_pit_channel_state) -> Self

Converts to this type from the input type.

impl PartialEq for PitChannelState

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for PitChannelState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
