Function tdx_guest::tdvmcall::setup_event_notify_interrupt
source · pub fn setup_event_notify_interrupt(
interrupt_vector: u64,
) -> Result<(), TdVmcallError>Expand description
The guest TD may request that the host VMM specify which interrupt vector to use as an
event-notify vector. This is designed as an untrusted operation; thus, the TD OS should be
designed not to use the event notification for trusted operations. Example of an operation
that can use the event notify is the host VMM signaling a device removal to the TD, in
response to which a TD may unload a device driver.
The host VMM should use SEAMCALL [TDWRVPS] leaf to inject an interrupt at the requestedinterrupt vector into the TD VCPU that executed TDG.VP.VMCALL
