Subject: [Qemu-devel] [PATCH 03/11] update halted state on mp_state sync
Date: Wed,  2 Dec 2009 11:48:14 -0200	[thread overview]
Message-ID: <1259761702-4041-4-git-send-email-glommer@redhat.com> (raw)
In-Reply-To: <1259761702-4041-3-git-send-email-glommer@redhat.com>

If we are using in-kernel irqchip, halted state belongs in the kernel.
So everytime we grab kernel's idea of mpstate, we also need to propagate
halted state to userspace.
