Struct ItsSignalMsi 

pub struct ItsSignalMsi { /* private fields */ }

A [SignalMsi] wrapper that prepends the PCI segment to the BDF, producing the ITS device ID.

When devid is Some(bdf), the ITS device ID is (segment << 16) | (bdf & 0xFFFF).

In the normal flow this wrapper is invoked via MsiTarget::signal_msi or MsiTarget::signal_msi_with_rid, both of which always pass Some(bdf), so the None arm is unreachable. It is retained as a defensive guard for direct trait callers that have no BDF to provide.

Implementations

impl ItsSignalMsi

pub fn new(inner: Arc<dyn SignalMsi>, segment: u16) -> Self

Creates a new wrapper for the given segment.
