Struct GicV2mSignalMsi 

pub struct GicV2mSignalMsi { /* private fields */ }

A [SignalMsi] implementation that decodes GIC v2m-style MSIs and delivers them as SPI assertions via ControlGic.

When a device fires an MSI it writes the assigned GIC interrupt ID to the SETSPI_NS register inside the v2m frame (frame_base + 0x0040). The host intercepts that write (or for software devices, synthesises it) and calls signal_msi with address = frame_base + 0x0040 and data = interrupt_id. This struct validates the address and SPI range then calls ControlGic::set_spi_irq.

Implementations

impl GicV2mSignalMsi

pub fn new(v2m: &GicV2mInfo, irqcon: Arc<dyn ControlGic>) -> Self

Create a new GicV2mSignalMsi from v2m frame info and a GIC controller.
