Struct Spcr 

pub struct Spcr {
    pub header: SdtHeader,
    pub parity: u8,
    pub stop_bits: u8,
    pub language: u8,
    pub pci_flags: u32,
    pub pci_segment: u8,
    /* private fields */
}

Serial Port Console Redirection (SPCR) Table.

The table provides information about the configuration and use of the serial port or non-legacy UART interface. On a system where the BIOS or system firmware uses the serial port for console input/output, this table should be used to convey information about the settings.

For more information, see the official documentation.

Fields

header: SdtHeader

parity: u8

stop_bits: u8

language: u8

Language which the BIOS was redirecting. Must be 0.

pci_flags: u32

pci_segment: u8

PCI segment number. systems with fewer than 255 PCI buses, this number will be 0.

Implementations

impl Spcr

pub fn interface_type(&self) -> SpcrInterfaceType

Gets the type of the register interface.

pub fn base_address(&self) -> Option<AcpiResult<GenericAddress>>

The base address of the Serial Port register set, if if console redirection is enabled.

pub fn baud_rate(&self) -> Option<NonZeroU32>

The baud rate the BIOS used for redirection, if configured.

pub fn flow_control(&self) -> SpcrFlowControl

Flow control flags for the UART.

pub fn interrupt_type(&self) -> SpcrInterruptType

Interrupt type(s) used by the UART.

pub fn irq(&self) -> Option<u8>

The PC-AT-compatible IRQ used by the UART, if the UART supports it. Support is indicated by the interrupt_type.

pub fn global_system_interrupt(&self) -> Option<u32>

The Global System Interrupt (GSIV) used by the UART, if the UART supports it. Support is indicated by the interrupt_type.

pub fn terminal_type(&self) -> SpcrTerminalType

The terminal protocol the BIOS was using for console redirection.

pub fn pci_device_id(&self) -> Option<u16>

If the UART is a PCI device, returns its Device ID.

pub fn pci_vendor_id(&self) -> Option<u16>

If the UART is a PCI device, returns its Vendor ID.

pub fn pci_bus_number(&self) -> Option<NonZeroU8>

If the UART is a PCI device, returns its bus number.

pub fn pci_device_number(&self) -> Option<NonZeroU8>

If the UART is a PCI device, returns its device number.

pub fn pci_function_number(&self) -> Option<NonZeroU8>

If the UART is a PCI device, returns its function number.

pub const fn uart_clock_frequency(&self) -> Option<NonZeroU32>

The UART clock frequency in Hz, if it can be determined.

pub fn namespace_string(&self) -> Result<&str, Utf8Error>

An ASCII string to uniquely identify this device. This string consists of a fully qualified reference to the object that represents this device in the ACPI namespace. If no namespace device exists, the namespace string must only contain a single ‘.’.
