From ec6959d0466fb240fe4d94d5f525eebf9ba18b84 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Wed, 13 Apr 2011 01:32:56 +0200 Subject: Redirect cpu_interrupt to callback handler This allows to override the interrupt handling of QEMU in system mode. KVM will make use of it to set a specialized handler.
