The current interrupt logic is just completely broken. We get a notification from user space, telling us that an interrupt is there. But then user space expects us that we just acknowledge an interrupt once we deliver it to the guest. This is not how real hardware works though. On real hardware, the interrupt controller pulls the external interrupt line until it gets notified that the interrupt was received. So in reality we have two events: pulling and letting go of the interrupt line. To maintain backwards compatibility, I added a new request for the pulling part. The letting go part was implemented earlier already. With this in place, we can now finally start guests that do not randomly stall and stop to work at random times. This patch implements above logic for Book3S. Signed-off-by: Alexander Graf <agraf@suse.de>
