pub struct MsiCapability { /* private fields */ }

Implementations

impl MsiCapability

pub fn has_per_vector_masking(&self) -> bool

Does device supports masking individual vectors?

pub fn is_64bit(&self) -> bool

Is device using 64-bit addressing?

pub fn get_multiple_message_capable(&self) -> MultipleMessageSupport

How many interrupts this device has?

pub fn ctrl(&self, access: &impl ConfigRegionAccess) -> u32

pub fn is_enabled(&self, access: &impl ConfigRegionAccess) -> bool

Is MSI capability enabled?

pub fn set_enabled(&self, enabled: bool, access: &impl ConfigRegionAccess)

Enable or disable MSI capability

pub fn set_multiple_message_enable( &self, data: MultipleMessageSupport, access: &impl ConfigRegionAccess )

Set how many interrupts the device will use. If requested count is bigger than supported count, the second will be used.

pub fn get_multiple_message_enable( &self, access: &impl ConfigRegionAccess ) -> MultipleMessageSupport

Return how many interrupts the device is using

pub fn set_message_info( &self, address: u32, vector: u8, trigger_mode: TriggerMode, access: &impl ConfigRegionAccess )

Set where the interrupts will be sent to

Arguments

• address - Target Local APIC address (if not changed, can be calculated with 0xFEE00000 | (processor << 12))
• vector - Which interrupt vector should be triggered on LAPIC
• trigger_mode - When interrupt should be triggered
• access - PCI Configuration Space accessor

pub fn get_message_mask(&self, access: &impl ConfigRegionAccess) -> u32

Get interrupt mask

Note

Only supported on when device supports 64-bit addressing and per-vector masking. Otherwise returns 0

pub fn set_message_mask(&self, access: &impl ConfigRegionAccess, mask: u32)

Set interrupt mask

Note

Only supported on when device supports 64-bit addressing and per-vector masking. Otherwise will do nothing

pub fn get_pending(&self, access: &impl ConfigRegionAccess) -> u32

Get pending interrupts

Note

Only supported on when device supports 64-bit addressing. Otherwise will return 0

Trait Implementations

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MsiCapability

fn fmt(&self, f: &mut Formatter<'_>) -> Result
