Interface InterruptAllocator

public interface InterruptAllocator
Allows reserving interrupts on the primary interrupt controller of a virtual machine during a VMDevice.mount(VMContext) call.

Allocated interrupts should be persisted and used in claimInterrupt(int) when restoring from a saved state to ensure correct behavior of the loaded virtual machine.

    • claimInterrupt

      boolean claimInterrupt(int interrupt)
      Tries to reserve an interrupt with the specified index. This may fail if the interrupt has already been claimed. Use claimInterrupt() to obtain a free interrupt.
      Parameters:
      interrupt - the interrupt to claim.
      Returns:
      true if the interrupt could be claimed; false otherwise.

      OptionalInt claimInterrupt()

      Returns:
      the interrupt that was claimed, if any.
