Struct MsixCapability

pub struct MsixCapability { /* private fields */ }

Implementations

impl MsixCapability

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

Enable MSI-X on the specified device feature.

Unlike with MSI, the MSI message data and delivery address is not contained within the capability, but instead in system memory, and pointed to by the BAR specified by MsixCapability::table_bar and MsixCapability::table_offset. The caller is therefore responsible for configuring this separately, as this crate does not have access to arbitrary physical memory.

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

pub fn set_function_mask(&mut self, mask: bool, access: impl ConfigRegionAccess)

Enable/disable masking of all interrupts for this PCI function.

Individual interrupt sources can be masked using mask field of the corresponding entry in the MSI-X table.

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

pub fn table_bar(&self) -> u8

The index of the BAR that contains the MSI-X table.

pub fn table_offset(&self) -> u32

The offset, in bytes, of the MSI-X table within its BAR.

pub fn table_size(&self) -> u16

pub fn pba_bar(&self) -> u8

pub fn pba_offset(&self) -> u32
