Implementations

impl CapabilityMsixData

pub(super) fn new(dev: &mut PciCommonDevice, cap_ptr: u16) -> Self

pub fn table_size(&self) -> u16

MSI-X Table size

pub fn set_interrupt_vector(&mut self, irq: IrqLine, index: u16)

pub fn irq_mut(&mut self, index: usize) -> Option<&mut IrqLine>

Gets mutable IrqLine. User can register callbacks by using this function.

pub fn is_enabled(&self) -> bool

Returns true if MSI-X Enable bit is set.
