[Qemu-devel] [PATCH v3 16/16] kvm: Arm in-kernel irqchip support


From: Jan Kiszka
Subject: [Qemu-devel] [PATCH v3 16/16] kvm: Arm in-kernel irqchip support
Date: Tue, 6 Dec 2011 13:58:16 +0100

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.
