Struct PciInterruptMechanism

Source 
pub struct PciInterruptMechanism<'a> { /* private fields */ }
Expand description

Gives you control over a PCI device’s specific interrupt mechanism, which may be INTx, MSI, or MSI-X.

Implementations§

Source§

impl PciInterruptMechanism<'_>

Source

pub fn max(&self) -> usize

Maximum number of vectors that may be enabled for this particular interrupt mechanism.

Source

pub fn enable(&self, eventfds: &[RawFd]) -> Result<()>

Enables vectors 0 through eventfds.len() - 1 of this particular interrupt mechanism.

Fails if eventfds.len() > self.max().

Source

pub fn disable(&self) -> Result<()>

Disables all enabled vectors of this particular interrupt mechanism.
