[Qemu-devel] qxl: qxl's event named "QXL_INTERRUPT_DISPLAY"

[楼正伟]

Hi, I'm learning about qxl device in KVM VM. I got a problem and asks
for help. Thanks.

The qemu's command is:
        qemu-system-x86_64 -spice port=5900,disable-ticketing -vga qxl
--enable-kvm ...

The code in function 'interface_get_command' is followed:
        SPICE_RING_POP(ring, notify);
        if (notify) {
            qxl_send_events(qxl, QXL_INTERRUPT_DISPLAY);
        }

What is the meaning about 'QXL_INTERRUPT_DISPLAY' ?
Does it means sending a 'QXL_INTERRUPT_DISPLAY' irq to vm?
If so, what's the irq's handler?

Thanks.
