Struct MsiCapability

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 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 multiple_message_enable( &self, access: impl ConfigRegionAccess, ) -> MultipleMessageSupport

Return how many interrupts the device is using

pub fn set_message_info( &self, address: u64, data: u32, access: impl ConfigRegionAccess, )

Set the memory address that will be written to when the interrupt fires, and the data that will be written to it.

pub fn set_message_info_lapic( &self, address: u64, vector: u8, trigger_mode: TriggerMode, access: impl ConfigRegionAccess, )

Set the memory address that will be written to when the interrupt fires, and the data that will be written to it, specialised for the message format the LAPIC expects.

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 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, mask: u32, access: impl ConfigRegionAccess)

Set interrupt mask

Note

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

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

Get pending interrupts

Note

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