From 6a48ffaaa732b2142c1b5030178f2d4a0fa499fe Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Sat, 15 Oct 2011 13:43:48 +0200 Subject: [PATCH] kvm: Activate in-kernel irqchip support Make the basic in-kernel irqchip support selectable via -machine ...,kernel_irqchip=on. Leave it off by default until it can fully replace user space models.
