impl MsiAddress

source

pub fn virt_destination(&self) -> u16

Returns a 15-bit destination encoded in the MSI address. This is not architectural–normally only an 8-bit destination is supported unless interrupt redirection is enabled–but this is supported by some virtualization platforms (including Hyper-V and KVM).

The high 7 bits are encoded as the high 7 bits of the extended destination field. The low bit of that field is ignored and presumed to be zero in this configuration.

source

pub fn with_virt_destination(self, destination: u16) -> Self

Returns a value with a 15-bit destination encoded as guests expect when running with Hyper-V or KVM virtualization extensions.

This updates the destination and extended destination fields.

source

pub fn set_virt_destination(&mut self, destination: u16)

Updates the value with a 15-bit destination encoded as guests expect when running with Hyper-V or KVM virtualization extensions.

This updates the destination and extended destination fields.
