From fb0e843a11abae5b959a4b02be7aef617c023b4e Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Thu, 13 Feb 2014 12:08:35 +1100 Subject: xics-kvm: Fix reset function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently interrupt priorities are set to 0 (highest) at the very beginning of the guest execution which is not correct and makes the guest produce random interrupt error messages such as: "Interrupt 0x1001 (real) is invalid, disabling it". This also prevents interrupt states from correct migration. This initializes priority to 0xFF as the emulated XICS does.
