Can AST2400 generate MSI to Host after xdma-engine complete a dma cycle?

I am using AST2400's xdma-engine to read and write memory of host. As the datasheet says, xdma-engine can generate a msi or intx interrupt to both BMC and host after complete a dma read or write. However I can only receive the interrupt in the BMC side, and the host side does not receive any interrupt.
Can some one help me?
