Struct MsiCapability 

pub struct MsiCapability { /* private fields */ }

MSI capability implementation for PCI configuration space.

Implementations

impl MsiCapability

pub fn new( multiple_message_capable: u8, addr_64bit: bool, per_vector_masking: bool, register_msi: &mut dyn RegisterMsi, ) -> Self

Create a new MSI capability.

Arguments

• multiple_message_capable - log2 of maximum number of messages (0-5)
• addr_64bit - Whether 64-bit addressing is supported
• per_vector_masking - Whether per-vector masking is supported
• register_msi - MSI registration interface

pub fn interrupt(&self) -> Option<Interrupt>

Get the interrupt object for signaling MSI.
